United Nations University
Abstract:
Reasoning about a distributed system that exhibits a combination of probabilistic and temporal behaviour does not seem to be easy with current techniques. The reason is the interaction between probability and abstraction, made worse by remote synchronisation. In this paper the recently proposed language ptsc (for probability, time and shared-variable concurrency) is extended by constructs for interleaving and local block. Both enhance a designer's ability to modularise a design; the latter also permits a design to be compared with its more abstract specification, by concealing appropriately chosen design variables. Laws of the extended language are studied and applied in a case study consisting of a faulty register-transfer-level design.

2. Growth, Inequality, and Poverty Reduction in Developing Countries

Working Paper
Institution:
United Nations University
Abstract:
The study presents recent global evidence on the transformation of economic growth to poverty reduction in developing countries, with emphasis on the role of income inequality. The focus is on the period since the early/mid-1990s when growth in these countries as a group has been relatively strong, surpassing that of the advanced economies. Both regional and country-specific data are analysed for the US$1.25 andUS$2.50 level poverty headcount ratios using the most recent World Bank data. The study finds that on average income growth has been the major driving force behind both the declines and increases in poverty. The study, however, documents substantial regional and country differences that are masked by this 'average' dominant growth story. While in the majority of countries growth was the major factor behind falling...

Abstract:
By exploring the export performances and specialization patterns of China and India, we assess their trade competitiveness and complementarity vis-à-vis each other as well as with the rest of the world. Our analysis indicates that (i) India faces tough competition from China in the third markets especially in clothing, textile and leather products; (ii) there is a moderate potential for expanding trade between the two countries; (iii) China poses a challenge for the East Asian economies, the US, and most of the European countries especially in medium-technology industries; (iv) India appears to be a competitor mainly for its neighbouring South Asian countries; and (v) complementarity exists between the imports of China and India, and the exports of the US, some European states and East Asian countries, especially Japan, Korea, Malaysia, Singapore and Thailand, implying opportunities for trade expansion; and finally (vi) the export structure of China is changing with the exports of skill intensive and high-technology products increasing and those of labour-intensive products decreasing gradually. This suggests that challenges created by China in traditional labour-intensive products might reduce in the long run.

4. China's Development Strategy and Energy Security: Growth, Distribution and Regional Cooperation

Author:
Haider A. Khan
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper analyses both global and regional approaches to solving problems of energy security and ecological imbalance by addressing specifically the problems of China's energy security. China's growing energy dependence has become a major concern for both economic and national security policymakers in that country. The ambitious goal of modernization of the economy along the lines of the other newly industrialized economies (NIEs) of Asia has succeeded only too well, and it is difficult to reorient economic priorities. If examined rigorously, such an economic strategic assumption can be seen to entail the goal of creating further technological capabilities. In particular, China seems to be firmly committed to the creation of a largely self-sustaining innovation system as part of a knowledge-based economy of the future. Such innovation systems, called positive feedback loop innovation systems or POLIS have been created by advanced countries, and NIEs such as South Korea and Taiwan are proceeding to create these as well. But this will add to its energy burden and further dependence on the US as the power which controls the key sea lanes. Only a strategic reorientation to building a self-sustaining POLIS and appropriate regional cooperation institutions can lead to the way out of the current dilemma for China. Fortunately, such a model of POLIS which is distributionally and ecologically sensitive can be built for China and applied strategically to lead towards a sustainable development trajectory.

5. China's Exports in ICT and its Impact on Asian Countries

Abstract:
This paper analyses China's ICT exports grow thin its two major markets Japan and the US from 1992 to 2004. It focuses on ICT products classified in SITC 75, 76 and 77. The empirical results show that Chinese exports had maintained two-digit annual growth during the period. The growth was much higher than the corresponding growth of the overall markets. By 2004, Chinese ICT exports accounted for 26 per cent of the total Japanese imports and 19 per cent of the total imports of the US in ICT products. In addition, the paper investigates whether the rapid growth of Chinese ICT exports crowded out that of other Asian countries: Indonesia, Malaysia, Philippines, Singapore, South Korea and Thailand. The empirical analysis shows that the crowding out effect differs across countries and products. The exports of Singapore and Philippines have been negatively affected by the growth of Chinese exports, but no crowding effect existed at all with Indonesia's exports.

6. Concentration among the Rich

Working Paper
Institution:
United Nations University
Abstract:
The aim of this paper is to examine the concentration of wealth among the group of top wealth holders, defined as those with wealth in excess of a high cut off. The paper begins by considering the definition of this cut off, analogous to the definition of a poverty line at the other end of the distribution. It then considers what can be learned about the proportion classified as 'rich' and about the concentration among the rich from four non-survey sources: journalists' lists, estate data, wealth tax data, and investment income tax data. It starts off from the world's billionaires in 2006, but is particularly concerned with changes over time within countries, taking France, Germany, the UK, and the USA, to illustrate the different sources.

Abstract:
Food insecurity and hunger have traditionally been measured by aggregate food supplies or by variables correlated with food insecurity. Because these measures often poorly reflect individuals' true deprivation, economists have turned to surveys with direct questions about food insecurity. Using these surveys, households have then been classified into broad categories, a classification system which ignores the richness of the multiple questions. In this paper, we propose food insecurity measures, along the lines of the well established poverty measures, which incorporates this richness and allow us to reflect the depth and severity, in addition to the incidence, of food insecurity. Using these indices, we calculate the extent of food insecurity and hunger in the United States. Along with giving a richer picture of food insecurity in the US, these food insecurity measures demonstrates that the ordering of various demographic categories differs depends on the choice of measure.

8. The Role of Federalism in Developing the US during Nineteenth-century Globalization

Working Paper
Institution:

Abstract:
During its development into a continental empire, the US, like other countries relied on the investment of capital and labour from abroad; unlike other countries, the US had a peculiar political institution, federalism, which channeled these resources and also determined the course of protest against these resources. The paper argues that federalism played a key role in determining the course of US economic development and reaction to this early instance of globalization, a role with possible lessons for other countries today.

9. Central Banks as Agents of Economic Development

Author:
Gerald Epstein
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
In the last two decades, there has been a global sea change in the theory and practice of central banking. The currently dominant 'best practice' approach to central banking consists of the following: (1) central bank independence (2) a focus on inflation fighting (including adopting formal 'inflation targeting') and (3) the use of indirect methods of monetary policy (that is, short-term interest rates as opposed to direct methods such as credit ceilings). This paper argues that this neo-liberal approach to central banking is highly idiosyncratic in that, as a package, it is dramatically different from the historically dominant theory and practice of central banking, not only in the developing world, but, notably, in the now developed countries themselves. Throughout the early and recent history of central banking in the US, England, Europe, and elsewhere, financing governments, managing exchange rates, and supporting economic sectors by using 'direct methods' of intervention have been among the most important tasks of central banking and, indeed, in many cases, were among the reasons for their existence. The neo-liberal central bank policy package, then, is drastically out of step with the history and dominant practice of central banking throughout most of its history.

Abstract:
Much has changed in international finance in the twenty years since UNU-WIDER was founded. This paper identifies five broad contours of what we might expect in the next twenty years: the flow of capital from ageing societies to the more youthful economies of the South; the growth in the financial services industry in emerging economies and the consequences for their capital flows; the current strength in emerging market debt, and whether this represents a change in fundamentals or merely the effect of low global interest rates; the impact of globalization in goods markets in lowering inflation expectations, and therefore global bond yields; and the implications of the adjustment in global imbalances between Asia (in particular China) and the United States for emerging bond markets as a whole. The paper ends by noting the paradox that today we see ever larger amounts of capital flowing across the globe in search of superior investment returns, and yet the financing needs of the poorer countries are still largely unmet.

11. Constitution Writing and Conflict Resolution

Author:
Jennifer Widner
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
Over 1975-2003 nearly 200 new constitutions were drawn up in countries at risk of conflict, as part of peace processes and the adoption of multiparty political systems. The process of writing constitutions is considered to be very important to the chances of sustaining peace, and The Commonwealth and the US Institute for Peace have developed good practice guidelines in this area. These emphasize consultation, openness to diverse points of view and representative ratification procedures. But assessing the impact of constitution-writing processes on violence is methodologically difficult, since there are many channels of influence in the relationship. This paper reports on preliminary findings from an ongoing research project into the effects of processes in constitution-writing. Regression analysis is used to control for important contextual features such as differences in income levels and ethnic diversity across countries. A key finding is that differences in the degree of participation in the drafting of constitutions has no major effect on post-ratification levels of violence in some parts of the world, such as Europe, but does make a difference in Africa, the Americas, and the Pacific together.

Working Paper
Institution:

Abstract:
This paper discusses development policy objectives, noting how these have changed over the years, with a more explicit focus on poverty reduction coming recently to the fore. It also examines the relationship between economic growth and poverty reduction. The paper then discusses how to achieve economic growth, starting with the caveat that growth must be environmentally sustainable, and moves on to the big question of the respective roles for the market mechanism and the state in allocating society's productive resources. The paper next discusses how economic reform has been implemented, and the political difficulties that arise. It concludes that getting development policy right has the potential to lift millions out of poverty.

13. The Economic Integration of Immigrants in the United States: Lessons for Policy

Working Paper
Institution:
United Nations University
Abstract:
The most important economic feature of immigration to the United States in the post-1965 period has been a significant deterioration in the economic performance of successive immigrant waves. The policy reaction to this trend would obviously differ if the entry wage disadvantage disappeared quickly, as the immigrants assimilated in the American economy and acquired skills and information valuable in the American labour market. This paper examines the determinants of economic assimilation, and discusses how the experience of earlier immigrant waves can provide valuable information about the assimilation process the new immigrants will likely experience.

14. Illegal Immigration, Human Trafficking, and Organized Crime

Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
It is important to make a careful distinction between illegal immigration, human smuggling, and human trafficking which are nested, but yet different concepts. This distinction is relevant because these different categories of the illegal movement of people across borders have quite different legal and political consequences. Human smuggling and trafficking have become a world-wide industry that 'employs' every year millions of people and leads to the annual turnover of billions of dollars. Many of the routes and enclaves used by the smugglers have become institutionalized; for instance, from Mexico and Central America to the United States, from West Asia through Greece and Turkey to Western Europe, and within East and Southeast Asia. More often than not flourishing smuggling routes are made possible by weak legislation, lax border controls, corrupted police officers, and the power of the organized crime. Naturally, poverty and warfare contribute to the rising tide of migration, both legal and illegal.

15. Regional Output Differences in International Perspective

Author:

Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
Accurate regional estimates of output are desired as an indicator of level of development and as a variable used to explain internal migration, demand patterns, fertility and other aspects of behaviour. This chapter explores one often neglected aspect of regional income differences, namely that due to price differences or regional purchasing power parities. When nominal regional income measures are adjusted for these price level differences they are termed real regional incomes. The preferred method of estimating regional purchasing power parities by detailed price comparisons is discussed for Brazil, the United States and the European Union. The empirical thrust of the chapter is an investigation of different methods for estimating regional real incomes based on PPP data for 167 countries and nominal regional incomes and other data for about 870 administrative areas at the subnational level. Even in their present form we believe the real income estimates provided for the geographical units present opportunities for understanding the world economic structure.

16. Irregular Migration and Asylum Seekers in the Caribbean

Author:
Elizabeth Thomas-Hope
Publication Date:

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
Irregular migration is increasing in the Caribbean while the opportunities for applying for asylum hardly exist. The policy regarding most Caribbean irregular migrants is based on the view of the potential destinations, namely that the migrants are economic rather than political refugees. Whatever the specific cause of a migrant's departure, the movement is rooted in a complex amalgam of political, socioeconomic and (increasingly) environmental, factors. Thus irregular movements are part of the wider Caribbean migration process. The irregular movements differ from other forms of migration in that they represent the informal sector of migration, providing an alternative to those sectors of national populations that for political or economic reasons fall outside the immigration categories for entry to the United States. Locations in the Caribbean largely provide the intended transit stops to the United States, but with the implementation of policies to interdict migrants at sea, many of these intermediary locations become final destinations and, ultimately, marginalized communities of the migrants themselves and successive generations. These centres are the nodal points of an established transnational network that sustains the ongoing process of irregular migration. The economic and emotional cost and risks faced by the migrants are high, and the economic and political cost and challenges faced by host governments are also high. Irregular migration and the issue of asylum poignantly reflect various aspects of poverty and the vast economic disparities that exist within the region. Further, irregular migration and the question of asylum greatly affect diplomatic relations between Caribbean countries of migration source and destination. Better and more thoughtful policies are needed to address the continuing issues relating to irregular migration.

17. Developed Country Trade Barriers and the Least Developed Countries: The Economic Results of Freeing Trade

Working Paper
Institution:
United Nations University
Abstract:
The Doha Ministerial Declaration emphasized that priority should be given to improving market access for products originating in the Least Developed Countries (LDCs). In this paper, we analyze the importance of this proposition with respect to market access in the Triad economies. We first present a brief history of non-reciprocal preferences granted by the Triad. This covers Generalized System of Preference (GSP) programmes in each, and further preferences granted to African, Caribbean and Pacific countries by the EU and preferences granted to Caribbean Basin, Andean, and African countries by the US. This history is followed by an assessment of trade generated by these preferences in the year 2000, and of the extent to which LDC exports might be expected to increase should the preferences be made comprehensive. Preferences in 2000 are shown to have led to an increase of US$3.5 billion in LDC exports, while a complete duty-free treatment could expand LDC exports by as much as US$7.6 billion, 90 per cent of which will be absorbed by the US. As this represents a doubling of LDC exports to these countries, we interpret these results as an endorsement of this priority in the Doha Round of negotiations.

18. Economic Integration and Migration: The Mexico-US Case

Abstract:
This paper explains the evolution and effects of Mexico-US migration, and highlights the NAFTA approach to economic integration, viz., free up trade and investment while stepping up efforts to prevent unauthorized migration. The European Union approach is different: provide aid first, and later free up trade and migration in the expectation that moves toward convergence will ensure minimal migration because trade has become a substitute for migration. The paper concludes that NAFTA will reduce unwanted Mexico-US migration in the medium to long term, and that different initial conditions in Europe mean that there will be relatively little east-west migration when nationals of new entrant EU members achieve freedom of movement.

Abstract:
The purpose of this paper is to outline trends and patterns in movements of asylumseekers to Western so-called industrialized countries from 1990-2001. The paper begins by characterizing three distinct phases of asylum migration since the end of the Second World War. It then provides background material on global refugee and asylum movements, using statistics from UNHCR. The data for selected receiving countries and regions is discussed, followed by some remarks on changing routes used by asylumseekers. The selected countries and regions are Australia, Canada, the EU and the USA. Finally, we examine some of the causal factors behind asylum migration and attempt to identify their significance upon flows migration.

Abstract:
This paper analyzes the "Silicon Valley model" as a novel economic institution in the domain of technological product system innovation such as computers. We focus on the information structural relationship as well as governance relationships between venture capitalists and a cluster of entrepreneurial firms. The informational conditions under which the Silicon Valley model is efficient are identified, leading to understanding the significance of standardization of interfaces, modularization and information encapsulation. We then examine the governance/incentive aspect of the model by integrating the models by Aoki (2001) and Baldwin and Clark (2000) to give comparative statics results regarding the optimal number of entrepreneurial firms competing in the same component product. The analyses enable us to evaluate the applicability of the model beyond specific localities and industries.
