1. Legacy of apartheid: Misallocation of labour and firm productivity

Abstract:
This paper investigates the extent to which the historical legacy of apartheid laws explains contemporary misallocation and firm productivity in South Africa. During the apartheid era (1948–1994), job reservations, closed-shop agreements, and minimum-wage policies were implemented to restrict occupational mobility for Black workers and to insulate White employees from competition. Using digitized historical data from government gazettes combined with contemporary employer-employee panel data, we identify sectors and districts where these restrictions applied and find persistent impacts on labour allocation today. Results show that historically restricted sector-district pairs exhibit between 4 and 14% more labour misallocation compared to unaffected counterparts. In contrast, we find no significant differences in average firm productivity in treated cells, suggesting that apartheid’s legacy on production persists primarily through allocative inefficiencies rather than observable differences in average firm efficiency. These findings underscore the persistent influence of discriminatory institutions on market efficiency and highlight the importance of policies aimed at correcting historical distortions in labour allocation.

Abstract:
This paper explores the role of informal taxation in the Democratic Republic of Congo and aims to shed light on informal fiscal realities and the implications of informal tax institutions for governance and state legitimacy. Relying on mixed-methods data from household surveys, interviews, and focus group discussions across Kinshasa and North Kivu, it focuses on three areas of inquiry: the nature of informal taxation; citizens’ perceptions of formal and informal taxing authorities; and the impact of informal taxation on perceptions of the state’s legitimacy. The paper finds that, while informal taxes place a significant burden on citizens, they may support local governance by supplementing public services and reinforcing perceptions of state legitimacy, particularly in the case of customary contributions. Overall, these findings highlight the complex interplay between informal and formal institutions, challenging assumptions that informal taxation solely undermines state authority. Its insights hold critical implications for scholars of informal governance and policy makers aiming to navigate hybrid governance structures in fragile states.

Abstract:
This paper examines the impact of temperature shocks on individual earnings and income inequality in South Africa. We leverage high-resolution satellite temperature data, merged with administrative tax records from the South African National Treasury and UNU-WIDER. Data from 2009 to 2022 shows that temperature shocks significantly reduce income, with a one-standard-deviation increase in average temperature associated with a 1 per cent decline in earnings and a 1.3 per cent decline in total income. However, we observe no statistically significant effects on income inequality. Temperature projections from the most recent climate models of the Coupled Model Intercomparison Project (CMIP6) are used to simulate the impact of global warming on income in the short, medium, and long term. By 2100, income is projected to decline by 5 per cent without mitigation and adaptation strategies, relative to a ‘best case’ scenario characterized by widespread adoption of renewable energy and climate change mitigation.

4. Social protection in South Africa

Working Paper
Institution:
United Nations University
Abstract:
South Africa has a relatively well-developed social protection system for a middle-income country. Despite its roots in the country’s racially discriminatory past, the system has been repurposed post-apartheid to address deep poverty and severe inequality. This paper explores key characteristics of the current social protection system, highlighting its large scale and reach. Given high unemployment, the scope of social insurance is relatively limited and the social protection system is largely geared toward s social assistance. Social assistance is well-targeted and has been found to have significant beneficial impacts on poverty and inequality, but also various other socioeconomic outcomes. A key gap in the formal social assistance system is the working-age population: able-bodied working-age adults are covered only by the COVID-19 social relief of distress grant, the introduction of which has reignited calls for the implementation of basic income support despite South Africa’s significantly constrained fiscal environment.

5. Gender and intergenerational mobility: Unequal economic outcomes between siblings

Author:

Publication Date:

Content Type:
Working Paper

Abstract:
This paper examines the role of sibling sex composition as a potential explanation of the transmission of parental advantages to the next generation. The presence of a brother affects the family environment and parents’ decisions, influencing the siblings’ labour market outcomes in the long term. The results show a negative effect of approximately 2% on the permanent income of women for the presence of a younger brother. This effect does not modify the intergenerational persistence of income. Regarding mechanisms, we find evidence that the effect is amplified when households face tighter budget constraints. Moreover, it is more pronounced in households with traditional gender norms, shaping permanent income, educational choices, and motherhood decisions. These findings underscore the importance of sociocultural mechanisms in accounting for the persistence of inequality.

Abstract:
The paper examines the structure of the social protection system in Egypt including its contributory and non-contributory components. It begins by examining the historical evolution of the system, its scale and reach, and its sources of financing. The book then assesses the de jure and de facto coverage of the system and the adequacy of payments for different kinds of workers and socio-economic groups. We end by examining the effectiveness of existing institutions in delivering social protection in light of the limited implementation capacity of the state, the incentive of firms to operate in the formal economy, and the potential tensions between individual participation in contributory social insurance and access to noncontributory social assistance.

7. Mapping mobility and opportunity: How place, gender, and ethnicity shape economic outcomes in Ecuador

Abstract:
Integrating administrative data from the civil registry, social security, and national censuses, we provide novel evidence on intergenerational income mobility and equality of opportunity among 514,890 formal workers in Ecuador. Our results show substantial intergenerational mobility (rank–rank slope 0.22, elasticity 0.17). Formal employment substantially equalizes mobility: gender differences are minimal, and ethnic disparities are compressed, although ethnic minorities face barriers at the bottom. Model-based recursive partitioning (MOB) endogenously identifies 63 spatially homogeneous areas based on intergenerational income elasticity (IGE) and highlights a large degree of variation, with elasticities ranging from 0.09 to 0.23. We complement our analysis with a Roemerian equality of opportunity framework using transformation trees, which shows that equality of opportunity is relatively limited: the worst-off earn 74% of average income, and circumstances predict 33% of total inequality. Our findings suggest that stable formal employment serves as an important equalizing mechanism for intergenerational mobility among formal sector workers, though the persistent ethnic disparities and spatial heterogeneity we observe point to remaining challenges in achieving equality of opportunity across all groups and regions in Ecuador.

Institution:

Abstract:
South Korea’s social protection system has undergone a profound transformation from a developmental welfare state, in which social protection policies were subordinated to the economic development goal, to a universal welfare state. This study traces this trajectory by examining six key programmes—Industrial Accident Compensation Insurance, National Health Insurance, National Pension, Employment Insurance, the National Basic Livelihood Security Scheme, and the Basic Pension—focusing on their functions, policy design, coverage expansion, and responses to new social risks. Findings show that initial programmes targeted formal-sector workers to support industrialization, but were gradually expanded to encompass broader populations. They were sequentially extended from large enterprises to small firms and then to the general population, with contribution rates increased incrementally to ensure administrative feasibility and fiscal sustainability. Democratization and electoral competition opened policy windows for universalization, while economic crises accelerated programme inclusivity. The analysis reveals that social protection facilitated structural economic transformation while progressively recognizing social rights. However, persistent labour market dualism, population aging, and high elderly poverty underscore the need for recalibrating Korea’s welfare system toward greater inclusivity and sustainability.

9. Intergenerational mobility through the lens of the elderly: New estimates from India and a comparison with existing measures

Abstract:
The literature on intergenerational mobility for many countries in the world focus on household surveys that capture the education of parents and their children. While they pay particular attention to issues regarding co-residency of fathers and son, they are somewhat weaker in information on women: daughters who live with their in-laws as well as resident women outside the reproductive age group (15--49), for whom information on parents is typically missing. In this paper we examine how estimates from a nationally representative survey of the elderly in India (LASI)---that over-samples adults who are 45 years and above and contains information about their parents---compare with existing studies that provide analogous estimates. We find that while estimates using father-son pairs are similar to extant literature on India, we can provide robust estimates for pairs that involve women, as parents and daughters, due to a relatively larger sample size, especially for the period before 1970s. Thus, we contend that LASI can be especially useful for studying temporal changes in human capital investment in daughters relative to sons.

Abstract:
The need for developing countries to increase their domestic revenue has always been relevant, especially after the COVID-19 pandemic, which weakened their public finances. This paper analyses the dynamic treatment effects of the Extractive Industries Transparency Initiative (EITI) implementation on resource revenue mobilization. We use a sample of 83 developing countries from 1995 to 2019, and our empirical strategy relies on the recent dynamic heterogeneity-robust difference-in-differences estimator. Our results show that implementing the EITI increases resource revenue in member countries through improved governance from greater transparency, increased foreign direct investment, and extractive resource exports. These findings are robust to several robustness checks. This study highlights the significant contribution of the EITI implementation in domestic revenue mobilization and the necessity to improve transparency in natural resources management, especially as international demand for critical mineral resources is expected to grow strongly.

Abstract:
This paper explores the forms of taxation practised by Al Qaeda and the Islamic State branches operating in Mali and Niger. It builds on insights from the rebel governance literature and an original conceptualisation of jihadist taxation and its effects. Unlike classic perspectives in the rebel governance literature, we argue for an ‘all at once’ approach to jihadist governance and warfare, where taxation is the beginning and the end of acts of warfare due to the fundamental political nature of Islamic taxation. Empirically, we stress the adaptiveness of jihadist groups to local circumstances, alternatively for doctrinal or pragmatic reasons.

Institution:

Abstract:
This paper examines the state and evolution of the rule of law in Mozambique, focusing on key dimensions such as voice and political participation, judicial independence and accessibility, corruption, access to basic services, personal security, and property rights. Drawing on Afrobarometer surveys, voting data, and conflict records, the paper offer insights into the perceptions and experiences of Mozambican citizens. The findings indicate a deterioration in institutional trust over the past two decades, alongside declining voter turnout in general elections and increasing election-related and political violence. Despite reforms aimed at improving judicial autonomy and accessibility, the legal system remains affected by inefficiencies and regional disparities. Citizens are often subject to bribery when accessing essential public services, and perception of corruption in key institutions remains high. Concerns about fairness and integrity in the land registration process can also weaken confidence in land security and property rights protection. The paper highlights the continued challenges Mozambique faces in consolidating the rule of law, exacerbated by legacies of conflict, political instability, and uneven socioeconomic development.

Abstract:
Since 1950, agricultural productivity has been increasing even as labourers leave agriculture. However, while average productivity of the sector has been converging, within-sector inequality has been increasing. Agricultural income inequality is still less than overall income inequality, but it measures significantly higher when we use higher-quality and more comprehensive survey data. This means not only to observe the entirety of household farm income, but also to measure the magnitude of capital income and corporate profits in the sector. Given the likely increase in agricultural inequality during the process of structural change, I show also the extent to which social protection programmes are both insufficient and poorly targeted for rural populations.

14. How reliable are national accounts estimates of agricultural output?

Author:
Sam Jones and Marcelo Mucocana
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
Measurement errors in macroeconomic aggregates such as GDP have been widely lamented, particularly in low-income contexts. This study investigates the reliability of one component of national accounts, agricultural sector output. Focusing first on the case of Mozambique, we use a series of 12 harmonized national agricultural micro-surveys to construct estimates of gross annual output in the sector. Compared to corresponding national accounts values for the period 2002–20, the micro-survey estimates are about 50% lower. A decomposition exercise indicates this gap is primarily driven by differences in base year levels, offset by higher rates of inflation observed in survey-based producer prices. Triangulating these estimates using household budget surveys, market price, and FAO production data, we find consistent support for the agricultural micro-survey estimates, suggesting real rates of total GDP growth may have been overestimated by 1 percentage point over the period. A cross-country comparison of national accounts and FAO production data indicates positive differences between estimates of agricultural output from the two sources are not unique to Mozambique, but with larger discrepancies among lower-income countries. Systematic investment in reliable and timely agricultural statistics is essential to track progress in the sector.

Abstract:
This study assesses the effectiveness of Mozambique's flagship social pension programme, the elderly component of the Programa de Subsídio Social Básico (PSSB). Focusing on three key criteria— programme targeting, reliability, and materiality—we combine administrative data on the universe of beneficiaries with the complete records of the 2017 Population and Housing Census. Merging these datasets at the localidade level, we provide a highly granular view of programme coverage rates and payment delivery regularity. We estimate that in the best case with zero targeting errors, the PSSB-Elderly programme reaches two-thirds of its target group. However, significant regional disparities persist, including undercoverage in poorer regions. Additionally, we document substantial delays in payments since 2023, as well as various inaccuracies in the beneficiary registry. These findings underscore the importance of simple and robust designs for social protection in resource-constrained contexts. They also suggest that expanding programme coverage towards a quasi-universal subsidy in high-poverty locations merits serious consideration.

Abstract:
In this paper, we first test the validity of the Environmental Kuznets Curve (EKC) hypothesis, using a large sample of approximately 190 advanced and developing countries, over a period of 34 years (1989– 2022). We find that (CO2) emissions respond positively to increasing income per capita, up to a turning point of approximately US$25,000. In a departure from the previous literature, we allow the relationship between economic development and emissions to depend on the stringency of environmental regulation. Our results indicate that environmental policies—and particularly market-based instruments, such as carbon taxes and emissions trading systems—make the EKC lower and flatter. These results are robust to several sensitivity checks, and to the use of regional (rather than global) data. Overall, our results have important policy implications, as they identify economic development as a pathway to environmental improvements. Moreover, we show that environmental policies are an essential means to achieving decoupling of emissions and economic output over the longer term.

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper investigates the effect of commodity price shocks in a commodity-exporting small open economy, and the role of fiscal policy in transmitting these shocks to the rest of the economy. Using South African data, we first estimate an empirical model using a Bayesian vector autoregression model. We then develop a New Keynesian small open economy with labour market hysteresis and commodity price shocks. We find that a commodity price shock typically has an expansionary effect as real GDP and employment increase, which translates into higher tax revenue. The results from our dynamic stochastic general equilibrium model match the data. In addition, despite not modelling the tradable and non-tradable sectors explicitly, we find that there is an opportunity cost associated with taxing the commodity sector more than home production. This results in a higher trade deficit and government spending. Consequently, we also explore the role of countercyclical fiscal policy during a commodity boom.

Publication Date:

Content Type:
Working Paper

Abstract:
According to the Kuznets hypothesis, inequality first tends to increase and then decrease as a country develops. Whether borne out empirically, this inverted-U Kuznets curve, as a stylized ‘fact’, has shaped the discourse on economic development and income inequality for decades. In this paper we investigate whether a similar relationship holds between national income per capita and inequality of opportunity: the inequality associated with inherited individual circumstances such as gender, ethnicity, and family background. As, empirically, inequality of opportunity is positively correlated with income inequality (a relationship known as the ‘Great Gatsby’ curve), the relationship between inequality of opportunity and ‘development’ is expected to display the same inverted-U shape. We suggest that the existence of a Kuznets inequality of opportunity curve can be the result of a ‘triangular’ relationship between development, income inequality, and inequality of opportunity. We propose a simple theoretical model that links the three concepts and describes two possible mechanisms. A numerical simulation based on the model illustrates the process. We then draw on the newly published Global Estimates of Opportunity and Mobility database to shed new light on this ‘triangular’ relationship, primarily in a cross-sectional context.

19. Surviving the storm: How climate-related disasters reshape tax morale in sub-Saharan Africa

Author:

Content Type:
Working Paper
Institution:

Abstract:
Climate-related disasters have increased over recent decades, with severe human and economic consequences. While research has examined their macroeconomic effects and impact on households’ income and consumption patterns, little attention has been given to their impact on tax morale—taxpayers’ intrinsic motivation to comply with tax obligations. This study fills this gap by estimating the impact of climaterelated disasters on tax morale in 26 sub-Saharan African countries using Afrobarometer survey data from 2011 to 2021. The analysis considers six climate-related shocks: droughts, earthquakes, extreme temperatures, floods, storms, and wildfires. We hypothesize that the impact of climate-related disasters on tax morale depends on the specific disasters considered, and that these heterogeneous effects work through two key mechanisms: economic inequality and trust in public institutions. First, they can exacerbate inequality by reducing government revenue, increasing economic hardship for vulnerable groups (through loss of livelihoods), and eliciting unequal policy responses from government. Climate-related disasters can also reduce inequality when associated with increased economic hardship for richer households (by destroying their productive assets. Second, tax morale declines when citizens perceive government responses as inadequate or unfair; conversely, it increases if citizens perceive the government to be responding adequately. Logistic regression results confirm this heterogeneity. Droughts, extreme temperatures, floods, and storms reduce tax morale, while earthquakes and wildfires increase it. Incorporating regional heterogeneity shows that the negative effects of disasters on tax morale are more profound in rural areas. Mediation analysis confirms inequality and institutional trust as key transmission channels. These findings underscore the need for inclusive tax policies and effective post-disaster governance to sustain revenue mobilization in sub-Saharan Africa.

Abstract:
This paper provides the first comprehensive analysis of how firms in emerging economies respond to carbon taxation, leveraging detailed administrative data from South Africa—a potential trailblazer for other developing countries with limited state capacity amid the growing global push for carbon pricing. We examine the dynamic impacts of the carbon tax on firm-level outcomes—such as profits, sales, capital, and labour inputs—across manufacturing and mining firms, which are key sectors in the context of the carbon tax. Contrary to concerns that carbon taxes may hinder economic growth or reduce employment, our findings show no evidence of negative average impacts on firm performance or jobs. However, this overall result masks significant heterogeneity in the tax’s effects across sectors, driven by the sector-specific design elements of the South African carbon tax. Firms expecting higher effective tax rates may have intensified their use of emission-intensive machinery and depreciated capital in anticipation of the tax. This behaviour appears to stem from firms resolving regulatory uncertainty or seeking to recover costs from stranded assets.

21. Rethinking development finance in Tajikistan: Towards more sustainable and inclusive fiscal pathways

Author:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper rethinks development finance in Tajikistan through the lens of fiscal sociology, arguing that sustained reliance on foreign aid and external borrowing may weaken state-society trust and erode institutional legitimacy. Anchored in the political economy of development finance, the paper explores how alternative financing strategies, such as tax reform, diaspora bonds, thematic bonds, and blended finance, interact with domestic institutions, investor confidence, and citizen perceptions of fiscal fairness. While external flows have financed essential infrastructure and social programmes, they have also limited incentives for domestic resource mobilization and weakened public accountability. Issues of debt sustainability increasingly constrain long-term planning, while climate finance is emerging as both a challenge and an opportunity for diversifying development funding. Drawing on policy analysis and secondary data, the paper shows that financial instruments succeed not only through technical design but through their ability to reinforce the fiscal social contract. Tajikistan’s case illustrates that without improvements in governance, transparency, and citizen engagement, even well-structured innovations in development finance may fail to gain traction. The findings offer practical insights for low-income countries seeking to reduce aid dependency while building more credible and inclusive systems of public finance.

22. Twenty-five years of inflation-targeting in South Africa: Going from 6% to 3%?

Author:
Philippe Burger
Publication Date:
06-2025
Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper proposes that the South African Reserve Bank should pursue a 3% inflation target, instead of the current 4.5% midpoint of a 3%-to-6% target range. Doing so may also result in lower inflation volatility, thereby reducing nominal exchange rate risk for investment and trade, and may thus support economic growth. Using a two-regime Markov-switching model, the analysis shows that since the global financial crisis, periods of higher inflation volatility are much shorter. Thus, inflation is relatively better anchored since the global financial crisis. But there are still shocks that coincide with periods of exchange rate volatility. Lastly, the analysis shows that the budget deficit/gross domestic product ratio, constraints on electricity supply, and administered prices contribute significantly to inflation, while the effect of real gross domestic product growth (as a demand variable) is limited. The analysis also argues that the sacrifice ratio, measuring the sacrifice of growth and employment that is required to reduce inflation, is of limited use once the potential role that other variables can play in the reduction of inflation and inflationary expectations is considered. The government has an especially significant role to play in supporting the South African Reserve Bank in lowering the inflation rate to an average of 3% by lowering the level and volatility of administered price inflation, reducing the budget deficit, and improving electricity supply.

Abstract:
Do criminal groups which help maintain order strengthen the fiscal contract or weaken it? This paper examines how the presence of organized-crime groups shapes Mexican municipalities’ ability to collect revenue, deliver public goods, and earn citizens’ trust. Survey data show that residents living in neighbourhoods home to organized crime report lower levels of trust in local government, regardless of whether those groups provide ‘order’ or engage in extortion and violence. Municipality-level data further reveal that both local revenue collection and public spending decline over time in areas with such a presence, independent of whether they are dominated by a single group (whereby crime syndicates’ provision of order is more likely) or see multiple organizations vie for supremacy (leading to extortion and violence being more commonplace). Evidence from Mexico suggests that criminal governance fractures the social contract locally: it erodes institutional trust, weakens municipalities’ fiscal capacity, and harms publicgood provision.

24. Digitalization and the politics of tax in low-income states

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
The digitalization of low-income economies has made it easier for governments to collect tax, yet many still fail to raise adequate revenues. Why would policy makers in urgent need of resources not fully leverage these new tools? I argue that governments remain constrained by public opinion: digital taxes are perceived as unfair, unaccountable, and lacking tangible benefit among the large groups of voters they affect. As a result, public support for digital taxes depends heavily on how they are designed. I test this argument with a conjoint experiment in Malawi focused on mobile transaction levies, a common form of digital tax introduced across Africa that has provoked strong backlash. Specific design choices, like earmarking revenues for local services or exempting small-scale users, can significantly affect support. This underscores broader political constraints on building fiscal capacity, even as technical limits on the state recede.

Abstract:
Knowledge of the factors driving people’s views on redistribution in the Global South remains limited. While these societies occupy top positions in inequality rankings, redistribution levels tend to be lower. We combine survey and experimental data from Mozambique and Viet Nam to test whether redistributive preferences vary depending on the source of inequality, focusing on two channels, fairness views and communication. First, we confirm the finding that inequality resulting from differences in merit is more accepted than inequality due to luck or factors outside of individual control. We also observe heterogeneity in fairness views. Second, we extend the analysis to consider whether allowing for communication between a receiver, who can suggest a distribution, and a dictator, who makes the final decision, affects redistribution preferences. We find that the relevance of the source of inequality remains. However, whether the expectation of the receiver is met by the dictator varies across samples and depends on the source of inequality. Overall, our results provide important insights into the universality of fairness views and point to the need for more analysis across contexts with different institutional and economic backgrounds.

Working Paper
Institution:

Abstract:
Sub-Saharan Africa (SSA)’s public debt burden remains a challenge to development. Key drivers of public debt include large-scale financing of infrastructure development, adverse impact of multiple shocks including COVID-19 pandemic, maturity mismatches, and high vulnerability to exchange rate and interest rate volatility. The tight financial conditions following interest rate hikes in advanced economies have exacerbated the debt burden and heightened debt sustainability risks. Half of the SSA low-income countries are either in debt distress or at high risk of it. Countries in debt distress include middle-income economies. Given the high cost of debt servicing and lack of fiscal space, achievement of sustainable development goals is in jeopardy. A long-term sustainable solution requires a multi-pronged approach. The G20 Common Framework for debt treatment remains limited in scope, coverage, and impact. More needs to be done including consideration for debt relief. Other strategies include access to long-term concessional finance, domestic resource mobilization, and improved efficiency in public spending and fiscal management.

Abstract:
Using publicly available databases and drawing on a wide range of indicators, this paper reviews the institutional performance of Mozambique across seven broad categories: rule of law and judicial independence; voice and freedom of expression/association; political participation; accountability and transparency; political instability and violence, and external relations; state legitimacy and political leadership; and governance and state capacity. Overall, the selected indicators point to similar trends within each dimension and suggest limited progress during the last decades. Still, it is fundamental that these insights and the scores presented by the indicators are put into context, and that we understand the historical path of Mozambique, the internal and external factors at play, and the fact that it takes time for progress achieved to be reflected in this type of data.

Abstract:
Following the abolition of slavery, various forms of compulsory labour were adopted by colonial powers to develop their economies. This paper analyses the contemporary consequences of compulsory cotton production—a forced labour system that operated in colonial Mozambique from 1926 to 1961. During this period, the Portuguese colonial government granted geographic concessions to private companies, within which smallholder farmers were forced to cultivate cotton for payment in cash. Women bore the brunt of this regime, but in doing so often took on responsibilities traditionally reserved for men and engaged in active resistance strategies. Employing a spatial regression discontinuity, we explore the enduring impact of this exposure to forced cotton cultivation on present-day human and social capital, focusing specifically on rural southern Mozambique. Our estimation strategy relies on the arbitrarily defined historical borders of the concessions, which reflected the tendency of concessionaires to absorb as much territory as possible, often ignoring agronomic conditions. Drawing on bespoke individual-level survey data collected along the concession border, we find lower educational outcomes among women in former concession areas. However, this is counterbalanced by positive effects on social capital, in the form of higher levels of civil participation, more progressive attitudes towards gender norms, and an increased presence of women in leadership positions. These results suggest that exogenous ruptures that push women outside traditional boundaries can help to reinforce their role in society.

Abstract:
Despite advancements for gender equality in some spheres, labour market outcomes for women continue to be worse than for men. Gender gaps in pay, labour force participation rates, and measures of job quality are stubbornly persistent and continue to hamper women’s economic empowerment globally. Economic development and social change should improve women’s labour market outcomes, but even with large-scale public policy actions, gender-based inequalities are difficult to address.

Abstract:
ross-border traders face a choice between official and unofficial border crossings. The latter allow them to evade taxes, but expose them to other risks, such as bribes, fines, and arrest. We investigate the perceptions of cross-border traders about the risks of trading officially vs unofficially at the border between Kenya and Uganda. We find that traders overestimate the risks of trading officially relative to the same risks when trading unofficially. In reality, the measured risks of trading through the official border are lower.

Abstract:
Frequent electricity outages threaten to impede the benefits of expanded access achieved by many developing countries in recent decades. A large literature documents these negative effects, however almost none consider labour market effects. This paper merges labour force survey microdata with high-frequency electricity supply and demand data to provide the first estimates of the relationships between outages and labour market outcomes in South Africa, a country characterized by frequent, severe outages referred to as load shedding. Exploiting temporal variation in outage incidence and intensity, we find that load shedding is associated with significantly lower employment rates, working hours, and earnings on average. Employment appears more sensitive relative to intensive margin outcomes, threatening job creation and preservation efforts. These negative relationships, however, are not evident for low levels of load shedding, but their strength markedly increases with load shedding intensity. We document further heterogeneity by firm size and industry, highlighting the vulnerability of jobs in manufacturing. Overall, our findings suggest that the South African labour market is largely insensitive to relatively low levels of load shedding; however, high levels appear especially costly.

Abstract:
We examine the nature of labour market inequality in Indonesia and India, using a common conceptual approach drawing from the job ladder framework. In the framework, we differentiate between self-employment and wage-informal and between formal, upper tier informal, and lower tier informal jobs. We find that both countries have a large proportion of workers in lower tier jobs, though the importance of wage-employment is larger in Indonesia. There are more workers in formal wage-employment in Indonesia than India. There are also sharp disparities in the earnings of workers in different tiers of the labour market in Indonesia and India, and there is limited evidence of convergence of the earnings of the lower tier informal workers to that of formal workers, at least for Indonesia. We also find that gender and educational level are important correlates of work status in both countries. Females and less educated workers occupy the lower tiers of the labour markets in the two countries.

Abstract:
We show that the Russia–Ukraine-war-induced changes in the international price of wheat affected political violence in Asia. Using data from 13 countries and more than four million cell-level observations, we show that a higher wheat price increases political violence in areas that are more suitable to produce that crop. We interpret this evidence as consistent with a rapacity effect being at play: the higher value of agricultural output increases the incentive to violently appropriate it. Our result is robust to a number of falsification and robustness tests. The effect is heterogeneous across countries and cell types: in line with our interpretation of the empirical findings, the effect is larger in countries that are net exporters of wheat and in cells that are rural. We also show that a higher price of wheat increases political violence more in countries that are low-income, fragile, and characterized by the presence of anti-government or terrorist groups, indicating that a higher value of crop production is more likely to fuel violence in areas that are poor or not politically stable.

Abstract:
We estimate structural, materials, and labour markups for the South African economy at the three-digit industry level for 2012–19. The fall in structural labour and materials markups found for the numerical majority of industries are generally isolated to smaller industries, with industries accounting for a higher proportion of sales generally experiencing smaller downward shifts. We show that materials-based markups are increasing over this period. Upward markup pressure in structural and labour markups are primarily driven by compositional shifts of surviving firms, while materials markup growth is driven by the average firm in a given sector. We show that merger intensity is positively related to structural markup growth, with a 1% increase in the proportion of cumulative mergers over 2013–18 being related to around a 0.27% increase in structural markup growth over the period from 2012 to 2019. We find that large vertical mergers are positively related to structural and materials markup growth while being negatively related to labour markup growth. Large horizontal mergers generally increase labour and structural markups.

Abstract:
Low-income countries face the combined challenges of climate shocks and limited domestic revenue mobilization, yet these issues are rarely studied together. This paper provides new evidence on the impact of climate shocks on firm performance and tax revenue in a low-income country context, using firm-level data from Zambia. We find that extreme weather events, such as excessive rainfall and high temperatures, significantly reduce firms’ sales, input purchases, and tax collection, particularly in sectors such as manufacturing, retail, accommodation, and construction. Firms respond by reducing employment and wages, reflecting a decline in productivity. Our findings highlight the need to consider the combined effects of climate shocks on both formal sector productivity and government revenue in developing countries, where taxation on services and goods (e.g. VAT) represents a larger share of government budgets.

Abstract:
Climate change and violent conflict are defining challenges of our time. However, it is not yet understood how they interact in shaping human welfare and food security, how their interaction shapes gendered outcomes, or how social protection systems can mitigate their impact. To address these knowledge gaps, we first examine how household food insecurity relates to conflict and climate shocks and whether these associations are gender-sensitive. Second, we test what mechanisms can reduce the negative impacts of these shocks. Our empirical analysis relies on novel survey data of 7,908 rural households collected across 14 states in Sudan in 2022. Sudan currently faces floods, droughts, and violent conflict affecting agricultural production and food supply. We find that climate shocks do not significantly affect food consumption scores (FCS), while exposure to violent conflict leads to a substantial decrease in FCS. Both productive and nonproductive assets increase FCS for all households, especially female-headed households. Longer distances to agricultural input and output markets correlate with lower FCS, particularly for maleheaded households. Women’s social group membership positively impacts on FCS for femaleheaded households. However, women do not receive additional benefits from other social networks during climate and conflict exposure, while male-headed households benefit from all types of social networks. Income diversification is identified as a key strategy for improving FCS, particularly for female-headed households during conflict. Informal cash transfers significantly improve FCS, especially for female-headed households. In contrast, formal cash transfers negatively correlate with FCS, although they positively impact on male-headed households during violent conflict. Overall, we recommend targeted social protection programmes that address gender disparities and enhance resilience among vulnerable populations.

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This study examines the sectoral impacts of electricity supply shortages in South Africa, using the cost share information available from the 2015 social accounting matrix. A simulation conducted under each of two technological assumptions, Cobb-Douglas and Leontief, reveals that a productivity decline in the electricity, gas, steam, and hot water supply (EGSH) sector increases the price of the EGSH sector substantially, while it affects the other sectors marginally due to the small cost shares of the EGSH factor in these sectors. The total cost of supplying the baseline final demand increases by ZAR19 billion or 0.46% of the baseline gross value added (GVA) when EGSH productivity declines by 10%. This cost impact expands to ZAR150 billion or 3.57% of GVA when EGSH productivity is halved. Large shares of these cost increments are incurred by the EGSH and manufacturing sectors, owning to the direct physical impact of productivity decline for the former and a large share of its sectoral GVA in the aggregate economy for the latter. The simulation also indicates that the equilibrium wage should increase by a greater extent for workers with a lower education than for those with a higher education if the baseline final demands are to be met at the higher EGSH output price after the sector’s productivity decline

Abstract:
This paper exploits several waves of two major nationwide representative surveys to document the impacts of climate shocks on individuals and households in Zambia. We merge these datasets with historical precipitation and temperature data at the district level. First, we show the gendered effects of the shocks, which have a higher negative impact on women. Women have a lower probability of being in the labourforce and fewer hours of work when experiencing shocks. Second, we show that households affected by climate shocks have 16% lower consumption, which is mainly explained by female-headed households. We show that social protection policies mitigate income reduction but not consumption, which may suggest that climate shocks affect households directly by reducing their income, but also indirectly by raising food prices.

Abstract:
Zambia’s reliance on rain-fed agriculture makes its economy and population highly vulnerable to frequent droughts and irregular rainfall. This paper assesses the role of social protection, specifically the Social Cash Transfer (SCT) program, in mitigating drought-induced poverty and consumption declines. Using the MicroZAMOD microsimulation model and districtlevel rainfall data, we find that rainfall shocks significantly increase poverty and reduce household consumption, disproportionately affecting the poorest households. While the current SCT program provides some relief, reforms to eligibility criteria, particularly removing the household composition requirement, could improve targeting, expand coverage, and strengthen resilience against climate-related economic shocks.

Abstract:
In this paper, we use a static fiscal incidence analysis model to evaluate the poverty and inequality impacts of using fiscal policy to finance expanded social spending in South Africa. We assess three methods to enhance the social protection system’s equity objectives: increasing the size and/or coverage of the existing Social Relief of Distress grant and introducing a universal or working-age basic income grant. The implications of financing these reforms are examined using four tax instruments: increasing the value-added tax rate, increasing personal income tax rates, reducing the personal income tax primary annual rebate, and introducing a surcharge on incomes. While we discuss behavioural effects, they are not included in the model. Our analysis indicates that an expansion of the social security system financed through increased taxation could substantially reduce poverty and inequality to varying degrees depending on the taxes and transfers used.

Institution:
United Nations University
Abstract:
The public-debt-to-GDP ratio in South Africa increased from 26 per cent in the 2008/09 fiscal year to 73.9 per cent in 2023/24, raising fears that fiscal policy is not sustainable. This raises the question: did the government take steps to arrest the increase in the debt-to-GDP ratio and regain fiscal sustainability, and if so, why did they fail? Establishing fiscal sustainability can be done directly or indirectly. Doing it directly entails the government increasing the primary balance in reaction to higher debt levels. Hence, this paper presents a fiscal reaction function. The analysis shows that during the period in which the public-debt-to-GDP ratio rose, the primary balance did indeed react to an increased debt burden, but its level remained too low to arrest the increase in the public-debt-to-GDP ratio. The analysis also assesses whether fiscal fatigue set in, wherein the responsiveness of the primary balance to the debt burden is positive but eventually weakens. Some evidence for the presence of fiscal fatigue is present. One indirect approach to establishing fiscal sustainability is through the impact of expenditure and revenue on economic growth. Leaving revenue for further study later, this paper presents an adapted growth equation to investigate the impact on growth of general government investment and consumption expenditure, and of public (and private) corporation investment. While the effect of private sector investment is positive, neither general government nor public corporation investment has a statistically significant impact on growth. Furthermore, government consumption has a negative impact on growth.

Carlos Gradín

Working Paper
Institution:
United Nations University
Abstract:
In this paper, I show that the trend in spatial inequality in Mozambique almost entirely explains the outstanding surge in inequality in the country over the past decade, as well as its decline immediately after the pandemic, in contrast to its secondary role in the earliest years. For this analysis, I use an innovative regression-based decomposition framework based on the Recentred Influence Function to estimate each area’s contribution to inequality and a Blinder– Oaxaca approach to disentangle the nature of their contribution to spatial and non-spatial inequality trends. This rise in inequality was mainly due to a generalized drop in consumption experienced by households in the afflicted rural areas in the north and centre of the country, affected by natural disasters and growing conflict. This was aggravated by disproportionally larger economic growth in two urban areas: the Maputo area, which encompassed the capital, during the expansive phase, and the urban area of coal-rich Tete province during the recession that followed. In more recent years, the crisis disproportionally affected the capital and other urban areas, producing a strong mitigating effect on inequality that might be only temporary. The findings of this research have the potential to significantly inform policy decisions to address inequality in Mozambique, thereby contributing to the country’s economic development substantially.

Abstract:
This study examines how different policy mix regimes affect the impact of recent US contractionary monetary policy on South Africa’s inflation and business cycles. The study uses a small open economy New Keynesian Dynamic Stochastic General Equilibrium model with an integrated fiscal block to analyse these effects. Regime M (active monetary policy) is more effective at containing the spillover effects but leads to higher public debt, requiring larger future fiscal surpluses. The commitment to price stability under Regime M increases real interest rates, raising domestic debt service costs and the debt-to-GDP ratio. Regime F (active fiscal policy), in contrast, stabilizes debt more quickly but at the cost of higher inflation, as it does not use future surpluses to manage public debt. These spillover effects are more amplified under both Regime M and Regime F in the case of a complete exchange rate pass-through and a higher degree of trade openness, with Regime F exhibiting a stronger amplification effect.

Content Type:

Institution:

Abstract:
South Africa’s current electricity crises have worsened, placing the country on an uncertain and turbulent economic trajectory. To identify the manufacturing sub-sectors that are most vulnerable to this crises, we use the input–output matrices for the period between 1993 and 2021 to develop a sub-sector energy vulnerability index. Second, we employ the self-constructed energy vulnerability index in a flexible empirical framework to examine the effect of the electricity crises on manufacturing sector jobs in the country. We find that energy vulnerability has a high degree of heterogeneity across manufacturing sub-sectors, highlighting cross-sector differences in the level of exposure and susceptibility to the energy-related crises. Results from the empirical analysis, on the other hand, suggest that electricity crises are associated with significant job destruction, with this adverse effect severe for manufacturing sectors with higher energy vulnerability intensity. The severity of this adverse effect holds irrespective of the nature of jobs, whether formal or informal.

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper critically examines the shortcomings of post-conflict reconstruction efforts in Afghanistan from 2001 to 2021, arguing that an overemphasis on measurable results and causal inference led to overly narrow, community-driven development interventions that failed to appreciate the complex political realities of the country. While these interventions espoused community control, they were in fact the result of a top-down approach reminiscent of earlier state-building efforts, neglected the importance of customary authority structures, and treated Afghanistan as a blank slate for experimentation. Such community-based programmes also lead to a myopic focus on quantifiable metrics at the expense of political considerations, reflecting a broader methodological bias in development studies exemplified by the popularity of randomized controlled trials. Drawing on extensive field observations, the paper contends that such programmes worked against the grain of Afghan society and paradoxically undermined the legitimacy and effectiveness of local governance institutions. The paper concludes by advocating a more holistic, adaptive, and politically informed approach to grassroots development in conflictaffected regions—one that empowers authentic local ownership, aligns with endogenous social and political structures, and grapples with the messy realities of fostering legitimate governance in fragile contexts. The hard-earned lessons from Afghanistan’s recent past should prompt a fundamental rethinking of what constitutes effective development assistance in post-conflict environments.

Working Paper
Institution:

Abstract:
Supporting state capacity is a priority for the international community, yet the record of internationally supported statebuilding to date has been mixed at best. A key question for continuing research concerns the factors influencing more versus less successful interventions. We show that the quality of past ‘stateness’ is crucial in understanding contemporary state fragility and statebuilding. Extending beyond previous work, we introduce the concept of past stateness, consider theoretically its relationship to contemporary fragility, and explore this relationship empirically, drawing on cross-national data and newly developed indicators. In line with our expectations, descriptive and inferential analysis shows that lack of experience of two core features of stateness—monopoly of violence and existence of a professional bureaucracy—in the past century predicts chronic fragility today. This association is mainly driven by monopoly of violence rather than existence of a professional bureaucracy. Our analysis sheds new light on the underlying heterogeneity among states today labelled as ‘fragile’. From a policy perspective, a key implication is that, in designing interventions, the most relevant experiences are likely to be from other countries with similar stateness legacies, rather than from ‘fragile states’ more generally. Our analysis does not imply that statebuilding is impossible in contexts with weak stateness legacies, but it does underscore the challenges of this and the importance of setting expectations appropriately.

Content Type:
Working Paper

Abstract:
In this paper, we use the new economic geography (NEG) framework to estimate the extent to which spatial wage disparities in the South African manufacturing sector are an outcome of economic forces such as market access. To test the relationship, we use the anonymized tax data on employers and employees made available by the South African Revenue Service and National Treasury in collaboration with UNU-WIDER. We first document the key stylized facts that characterize the spatial distribution of wages across regions in South Africa using exploratory spatial data analysis (ESDA) techniques. We then test for the existence of a wage structure across South African local and metropolitan municipalities, controlling for individual and firm characteristics using a two-stage estimation method. Consistent with the NEG predictions, we find that wages are higher in municipalities that are closer to large markets, as measured by the Harris market potential index. However, much of the wage effect is driven by the income and employment density of the municipality’s own market, and not that of surrounding areas. These results point to a combination of large spatial rigidities leading to highly localized effects of market potential, together with wage and productivity effects arising from urban agglomeration economies.
