Abstract:
We provide evidence for heterogeneous consumer preferences for product quality and game outcome uncertainty (GOU) in Major League Baseball. Using attendance data from 2013 to 2019, we explore func-tional data clustering techniques to detect common patterns in predictive margins of team-specific win-ning probability. As a central result, we identify five groups of teams with similar GOU effects. However, only a few teams’ fans show GOU preferences that resemble the typical hump-shape that is postulated by the uncertainty of outcome hypothesis; the largest cluster is comprised of teams with fans whose at-tendance behavior is relatively insensitive to differences in GOU.

302. Consumer and employer discrimination in professional sports markets – New evidence from Major League Baseball

Chair for Economic Policy, University of Hamburg
Abstract:
We investigate the relationship between consumer discrimination, racial matching strategies, and employer discrimination in Major League Baseball (MLB) from 1985 to 2016. To this end, we assess the extent to which both fan attendance and team performance respond to changes in teams’ and their local market areas’ racial compositions. We innovate by using a significantly enhanced data basis with individual player data that we derive from combining web scraping and using facial recognition techniques to identify player race and using County-level Census data instead of Metropolitan Statistical Area data. We find that fans in both MLB Leagues developed a taste for racial diversity in the late 1980s; since the 2000s, discrimination starts to increase again. However, this discrimination is not fully rationalizing the performance gap across athletes of different race and ethnicity; employer discrimination is not primarily driven by fans’ racial preferences.

Abstract:
The evidence can no longer be ignored: when women and feminist activists are able to use their collective power to challenge inequalities, they are having a transformational impact. From women’s rights organizations and movements breaking down harmful social norms, to political leaders advancing highly progressive policies, there is a growing body of evidence from feminist organizing across the world that when decisions are made more equally and inclusively, and are rooted in locally-owned, intersectional feminist movements and political agendas, they have immediate and long-term human development benefits for all.

304. Centring Gender and Power in Evaluation and Research: Sharing experiences from Oxfam GB’s quantitative impact evaluations

Institution:
Oxfam Publishing
Abstract:
Bringing a feminist intent to research, monitoring and evaluation practices leads to defining these as tools to contribute to transforming the lives of women, girls and non-binary people, and to bringing about social justice. This has meant putting gender and power at the centre of our practice, which has in turn shaped the technical choices made specifically in quantitative impact evaluations. This paper focuses on describing how these technical choices, as well as ethical considerations, are changed by this feminist intent. The paper also presents the lessons learned and questions raised along the way, which may be useful for MEAL and research practitioners, as well as programme managers. How can we bring intersectionality to the fore? What does it mean to go beyond the gender binary? How can this work be transformative?

Abstract:
As we continue to fight against the COVID-19 pandemic, it is vital that no one is excluded from vaccine coverage. This briefing note addresses some of the challenges faced by displaced people – including refugees, asylum seekers, IDPs, stateless people, and others in displacement contexts – in accessing COVID-19 vaccinations. It identifies a range of administrative and logistical barriers, the issue of lack of information and vaccine hesitancy, and gender-specific barriers to access for these populations. The briefing note provides recommendations to governments, UN agencies, and other actors to help address these challenges and ensure vaccine access for all displaced people.

306. Can climate change be tackled without ditching economic growth?

Author:

Content Type:
Working Paper
Institution:

Abstract:
Higher levels of economic activity tend to go hand-in-hand with additional energy use and consumption of natural resources. As fossil fuels still account for 80 percent of the global energy mix, energy consumption remains closely related to greenhouse gas emissions and hence to climate forcing. This paper explores whether decarbonisation and economic growth are compatible or whether the world economy needs to grow less to be able to reduce greenhouse gas emissions fast enough to reach net zero in 2050. The literature provides profoundly different answers to this question, with scholars positioning along a spectrum that extends from the most optimist version of ‘green growth’ theories to sceptical ‘degrowth’ theories. While globally, CO2 emissions per unit of GDP are declining, the decoupling rate from 1995 to 2018 was only -1.8 percent annually. To achieve net zero by 2050, the rate would have to accelerate to -8.7 percent, assuming population and GDP growth projections as given, or by a factor of almost five. To keep GDP growth and population at their projections and thus reject the proposition of de-growth, decoupling would have to accelerate massively. Two avenues are crucial: reducing the energy intensity of production and/or the emissions intensity of energy. The huge fall in the price of renewable energy provides hope that decoupling can accelerate. Decoupling rates have accelerated in the last decade and decoupling is substantially faster in the European Union. In the EU, we estimate that decoupling only has to accelerate by a factor of 2.5. We do not think degrowth propositions advanced in the literature will be pursued and therefore focus on the main challenges that must be tackled to achieve decoupling. Unprecedented efforts are required to achieve green growth. But hoping for humanity to sacrifice growth appears unrealistic.

307. Does money growth tell us anything about inflation?

Author:
Francesco Papadia and Leonardo Cadamuro
Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
Economists and central bankers no longer consider monetary aggregates relevant for inflation forecasts. We explain this neglect by advancing and testing the hypothesis that monetary aggregates are only relevant for inflation in unsettled monetary and inflationary conditions. When inflation is basically stable around the central bank target (1.9 percent), as it has been in most of the last two decades, there is no apparent relationship between monetary aggregates and inflation. This is not surprising: there is not much to be explained about a constant.

308. Towards efficient information sharing in network markets

Publication Date:

Content Type:
Working Paper
Institution:

Abstract:
Digital platforms facilitate interactions between consumers and merchants that allow collection of profiling information, which drives innovation and welfare. Private incentives, however, lead to information asymmetries resulting in market failures both on-platform, among merchants, and off-platform, among competing platforms. This paper develops two product-differentiation models to study private and social incentives to share information within and between platforms. We show that there is scope for ex-ante regulation of mandatory data sharing that improves social welfare better than competing interventions, such as barring entry, break-up, forced divestiture or limiting recommendation steering. These alternate proposals do not make efficient use of information. We argue that the location of data access matters and develop a regulatory framework that introduces a new data right for platform users, the in-situ data right, which is associated with positive welfare gains. By construction, this right enables effective sharing of information together with its context, without reducing the value created by network effects. It also enables regulatory oversight but limits data privacy leakages. We discuss crucial elements of its implementation in order to achieve innovation-friendly and competitive digital markets.

309. mRNA vaccines: a lucky shot?

Abstract:
MRNA technology has proved in the context of the COVID-19 pandemic its breakthrough value as a basis for vaccines. There has been rapid development of highly safe, effective and robust mRNA vaccines, and these can be delivered at large scale. Yet the technology is the result of a long process of accumulation of innovation and capacity. It was a bumpy process that could easily have turned out differently. The mRNA vaccines story suggests that a vibrant vaccine ecosystem cannot be taken for granted in terms of delivering the breakthroughs needed for global pandemic preparedness and response. This paper examines the background of mRNA technology development to understand better how public vaccine research and development policy can be improved to generate the full global social benefits from breakthrough novel vaccine technologies, like mRNA.

310. Market power and artificial intelligence work on online labour markets

Abstract:
The views are those of the authors and should not be regarded as stating an official position of the European Commission. Frank Mueller-Langer gratefully acknowledges financial support from a research grant of the University of the Bundeswehr Munich. We investigate three alternative but complementary indicators of market power on one of the largest online labour markets (OLMs) in Europe: (1) the elasticity of labour demand, (2) the elasticity of labour supply, and (3) the concentration of market shares. We explore how these indicators relate to an exogenous change in platform policy. In the middle of the observation period, the platform made it mandatory for employers to signal the rates they were willing to pay, as given by the level of experience required to perform a project: entry, intermediate or expert level. We find a positive labour supply elasticity ranging between 0.06 and 0.15, which is higher for expert-level projects. We also find that the labour demand elasticity increased while the labour supply elasticity decreased after the policy change. Based on this, we argue that market-designing platform providers can influence the labour demand and supply elasticities on OLMs with the terms and conditions they set for the platform. We also explore the demand for and supply of AI-related labour on the OLM under study. We provide evidence of a significantly higher demand for AI-related labour (ranging from +1.4 percent to +4.1 percent) and a significantly lower supply of AI-related labour (ranging from -6.8 percent to -1.6 percent) than for other types of labour. We also find that workers on AI projects receive 3.0 percent to 3.2 percent higher wages than workers on non-AI projects.

311. Timely measurement of real effective exchange rates

Author:
Zsolt Darvas
Publication Date:
12-2021
Content Type:
Working Paper
Institution:
Bruegel
Abstract:
We demonstrate that short-run real exchange effective rate changes are dominated by nominal effective exchange rate changes, while inflation rates are sticky and contribute little to short-run real exchange rate changes. These observations allow a rather accurate real-time approximation of the real effective exchange rate using actual nominal exchange rate data and forecast inflation data. We measure the approximation error and find it is minor for most countries and sizeable only for a few countries experiencing high and volatile inflation. For a set of countries, the revision in our estimates using real-time data is slightly lower than the revision in World Bank estimates and much lower than International Monetary Fund estimates. By considering two widely studied economic issues, unit root testing in real exchange rates and nominal exchange rate forecasting with the real exchange rate, we find that using a version of real exchange rates based on approximated monthly price level data instead of actual price level data hardly changes the conclusions on unit roots and forecasting. By combining alternative data sources for exchange rates and consumer prices, we calculate up-to-date monthly real effective exchange rates for 177 countries and the euro area. Our dataset, which is frequently updated, includes more than twice as many observations as the second most comprehensive dataset.

312. Climate-related Security Risks in the 2020 Updated Nationally Determined Contributions

Author:
Elise Remling and Amar Causevic
Publication Date:

Content Type:
Working Paper
Institution:
Stockholm International Peace Research Institute
Abstract:
Nationally determined contributions (NDCs) are the central instrument for states to communicate their con­tribution to the 2016 Paris Agreement on climate change and reflect their wider approach to climate mitigation and adaptation. This SIPRI Insights paper analyses how the 2020 updated NDCs (16 submissions as of October 2020) discuss climate-related security risks and compares them with 2015. It finds that climate change is mainly seen as a risk to socio-economic development and human security and almost never as a risk to societal stability or the functioning of the state. The assessment of risks in NDCs largely focuses on direct climate impacts. This suggests that countries are currently not considering the risks from indirect climate impacts, including those that cross national borders, or the unintended adverse con­sequences of adaptation or mitigation responses. Going forward, countries will need to take account of the multi­faceted and transboundary character of climate risks in their NDCs in order to meet global expectations and goals.

Abstract:
Artificial Intelligence (AI) is slowly moving past the public bewilderment phase that is common to most revolutionary technologies. In the past decade, AI has often been portrayed as either a sentient technology with an apocalyptic destiny, or as a silver bullet for most if not all conceivable problems ranging from the climate emergency to global crime prevention. This article contributes to a more recent and realistic assessment that is beginning to see the light: AI is a powerful technology that can help us address a wide range of well-defined problems given proper design, development, integration and monitoring.

Abstract:
How does immigration affect export performance? To answer this question, we propose a unified empirical framework allowing to disentangle various mechanisms put forth in previous literature. These include the role of networks in reducing bilateral transaction costs as well as productivity shifts arising from migration-induced knowledge diffusion and increased workforce diversity. While we find evidence supporting all three channels (at both the intensive and the extensive margins of trade), our framework allows to gauge their relative importance. We then focus on diversity and find stronger results in sectors characterized by more complex production processes and more intense teamwork cooperation. This is consistent with theories linking the distribution of skills to the comparative advantage of nations. The results are robust to using a theoretically grounded IV approach combining three variations on the shift share methodology.

315. Better Two Eyes than One: A Synthesis Classification of Exchange Rate Regimes

Working Paper
Institution:
Centre d'Etudes Prospectives et d'Informations Internationales (CEPII)
Abstract:
This paper proposes a new de facto classification of exchange rate regimes, the synthesis classification. The proposed framework has several advantages over existing de facto classifications. First, it offers a unified framework based on the most divergent classifications, the RR and LYS classifications, leading not only to a broader coverage but also to encompass a broad spectrum of exchange systems. Second, it fits better with the known history of exchange rate regimes developments in the post-Bretton Woods era. Among others, it brings an interesting nuance to the so-called hollowing-out hypothesis by showing that the evolution of de facto regimes —especially in emerging economies since the late 1990s— has essentially involved movement toward more tightly “managed” intermediate regimes and not a shift away from such regimes. As an illustration of the insightfulness of our classification, we empirically revisit the nexus between currency crises and exchange rate regimes. In addition to associate a higher probability of currency crisis to both intermediate and floating regimes, our classification, also displays better statistical performances than other classifications in predicting currency crises.

316. The Impact of Common Law on the Volume of Legal Services: An International Study

Abstract:
We show that the heavy use of legal services relative to output in the US is not a peculiarity of the country but applies to common law countries in general. It stems largely from better ability to contract and easier access to justice. Yet in close association, common law also opens significantly more room for rentseeking by lawyers than civil law. Thereby the costs could outweigh the benefits. Both real GDP per capita and openness emerge as further factors making room for lawyers.

317. Love of Variety and Gains from Trade

Author:
Christophe Gouel and Sébastien Jean
Publication Date:

Content Type:
Working Paper
Institution:
Centre d'Etudes Prospectives et d'Informations Internationales (CEPII)
Abstract:
This paper shows how gains from trade are conditioned by love of variety, defined as the extent to which an additional product variety generates benefits in either final or intermediate consumption. We develop a multi-country, multisector gravity trade model where love of variety is parameterized separately from product substitutability using a generalized CES demand function, and show analytically how gains from trade depend on love of variety through different channels that we identify and interpret. In this context, except for very specific parameterizations, gains from trade differ between a heterogeneous- and a homogeneous-firm model. Counterfactual simulations based on a calibrated version of this model show that, all other things being equal, the assessed gains from trade commonly vary by a proportion of one to three depending on the value of the love-of-variety elasticity, in a way that differs significantly across countries. Trade war simulations also point to the strong sensitivity of the assessed impacts. We conclude that love of variety is a key determinant of the gains from trade, an aspect that has so far been overlooked for the sake of convenience in the modeling framework and due to lack of empirical estimates.

Abstract:
Many of the measures to contain Covid-19 severely reduced business travel. Using provisions to ease the movement of business visitors in trade agreements, we show that removing barriers to the movement of business people promotes trade. To do this, we first document the increasing complexity of Free Trade Agreements. We then develop an algorithm that combines machine learning and text analysis techniques to examine the content of FTAs. We use the algorithm to determine which FTAs include provisions to facilitate the movement of business people and whether those provisions are included in dispute settlement mechanisms. Using these data and accounting for the overall depth of FTAs, we show that provisions facilitating business travel indeed facilitate business travel (but not permanent migration) and, eventually, increase bilateral trade flows.

319. Poor Substitutes? Counterfactual methods in IO and Trade compared

Author:
Keith Head and Thierry Mayer
Publication Date:
12-2021
Content Type:
Working Paper
Institution:
Centre d'Etudes Prospectives et d'Informations Internationales (CEPII)
Abstract:
Constant elasticity of substitution (CES) demand for monopolistically competitive firm-varieties is a standard tool for models in international trade and macroeconomics. Inter-variety substitution in this model follows a simple share proportionality rule. In contrast, the standard toolkit in industrial organization (IO) estimates a demand system in which cross-elasticities depend on similarity in observable attributes. The gain in realism from the IO approach comes at the expense of requiring richer data and greater computational challenges. This paper uses the dataset of Berry et al. 1995, who established the modern IO method, to simulate counterfactual trade policy experiments. We use the CES model as an approximation of the more complex underlying demand system and market structure. Although the CES model omits key elements of the data generating process, the errors are offsetting, leading to reasonably accurate counterfactual predictions. For aggregate outcomes, it turns out that incorporating non-unitary pass-through matters more than fixing over-simplified substitution patterns. We do so by extending the commonly used methods of Exact Hat Algebra and tariff elasticity estimation to take into account oligopoly.

Abstract:
What will the global economy look like in a generation? The answer depends on the multiple forces driving long-term growth (demography, education, diffusion of technical progress, energy costs, investment and saving behaviour, international capital mobility) and requires a comprehensive framework to conceptualise them. We re-estimate the three-factor (capital, energy, labour) MAcro-econometric model of the Global Economy (MaGE), initially developed by Fouré et al. (2013), with a database covering 170 countries using state-of-the-art methods. We thus establish the long-term structural relationships that drive the dynamics of the World economy. The model projections to 2050 illustrate the expected changes in the World economy and their driving forces. In light of the projected volume of energy consumption, making these projections compatible with climate imperatives calls for increased technology sharing at the international level in order to decouple economic growth from energy use.
