Vibert's European union: A United Nations or a United States?

In his book, Europe: A Constitution for the Millennium, Frank Vibert explores every major issue that will arise in the design of a constitution for a European political union. Can the theoretical constructs of constitutional economics be used to aid in the practical design of a European constitution? This is what Vibert attempts to do in his book. This review contains a more detailed discussion and analysis of a few of Vibert's main theses. In particular, it focuses, on several key issues that will be the major determinants of whether the European Union will achieve lasting success.     

The brain drain and the world distribution of income

Skilled emigration (or brain drain) from developing to developed countries is becoming the dominant pattern of international migration today. Such migration is likely to affect the world distribution of income both directly, through the mobility of people, and indirectly, as the prospect of migration affects the rate of return to education in both the sending and receiving economies. This migration pattern will therefore affect human capital accumulation and fertility decisions in both the sending and receiving economies. This paper analyzes these effects in a dynamic two country model of the world economy where agents in both countries make optimal fertility and human capital decisions. The implications of the analysis for the world distribution of income are derived in the light of recent empirical findings of the brain drain literature. The analysis shows that the current trend towards predominantly skilled emigration from poor to rich countries may in the long run increase inequality in the world distribution of income as relatively poor countries grow large in terms of population. In the short run however, it is possible for world inequality to fall due to rises in GDP per capita in large developing economies with sufficiently low skilled emigration rates.     

An Empirical Analysis of the Effect of Aid on Growth

The fact that so many countries register low per capita income after receiving enormous amounts of foreign aid questions its effectiveness as a tool for economic growth and consequently as an instrument of poverty alleviation. The impact of foreign aid on economic growth is ultimately an empirical question and one that will be addressed in this paper. The paper uses the most recent data and incorporates most of the salient features of the new growth literature to test the effect of aid on economic growth. Three important conclusions emerged from the empirical analysis of the paper. First, it shows that the effect of aid on growth is nonlinear. The nonlinearity of the relationship indicates a threshold for foreign aid beyond which more aid is detrimental to economic growth. Second, the empirical results of this paper support Burnside and Dollars findings that a good policy environment is important for aid to work effectively. Aid effectiveness can only be sustained in an environment of good economic policy. Finally, using etholinguistic fractionalization as an instrument, the empirical results of the paper indicate that the relationship between AID/GDP and economic growth is sequential. More and more aid leads to lower economic growth.The authors would like to thank W. Mark Crain, G.

The optimal sequencing of carrots

When aid organizations contract with local agents aid funds have the potential to be diverted to purposes other than the intended project. A multi-stage game is presented where the benefit from the project is cumulative, with the application of funds in each stage increasing both the agent's and the organization's benefit from the project. As the agent's utility of diversion increases, the allocation in each stage decreases and the project takes more stages to complete. When contracting with agents with high utilities of diversion the optimal contract involves bloated projects and a side payment to the agent upon completion. If the organization's commitment to the contract is not credible both the agent's and the organization's benefit is reduced.     

The trade balance and the terms of trade in a two-country two-sector OLG economy

We consider a two-country, two-sector OLG model. It is shown that the trade balance and the relative price of exports are always positively related when exports are labor intensive regardless of the elasticity of intertemporal substitution in consumption. A large response of savings to future prices becomes a sufficient condition for an inverse relation between these variables only if exports are capital intensive. In this case, a rise in the terms of trade can be followed by a trade balance decline if consumption goods are capital intensive and the income effect implied on savings is negative and large.     

Nationalism and government effectiveness

Nation-building is believed to have a positive influence on economic and political outcomes, especially in countries with ethnically fragmented populations. Yet nationalism, an indicator of successful nation-building, has been empirically linked to protectionism and intolerance, which suggests that dismal performance is a more likely outcome. This paper empirically identifies an inverted U-shaped relationship between nationalism and government effectiveness. The results suggest that the level of nationalism in the population is higher than optimal in most countries. It is further shown that nationalism may mitigate the negative effects of ethnic heterogeneity in former colonies. We find no clear linkages between nationalism and trade openness.     

The economic constitution of the European community: From Rome to Maastricht

The present paper analyzes the changes in the economic constitution of the European Community since its foundation in 1958. In order to identify the various changes, we start by developing a frame of reference. Our proposition is that theconstitutional charter of the European Economic Community (EEC)—the EEC Treaty—came closest to this frame of reference, being an economic constitution for a market system, whereas the subsequentprocess of European integration—including several modifications of the Treaty—was largely based on the introduction of non-market elements. Our argument is that as far as the economic constitution is concerned, the Treaty of Maastricht is dominated by traits which are characteristic of modern welfare states.     

A UNIFIED ANALYSIS OF TRADE GAINS IN THE PRESENCE OF PUBLIC GOODS*

It has long been known that free trade is potentially (after lumpsum compensatory transfers) beneficial for each trading country if the autarkic and post‐compensation free‐trade equilibria are perfectly competitive, with market distortions limited to non‐negative taxes on imports and exports. However these conditions are merely sufficient. It can now be shown that, under alternative sufficient conditions, free trade is potentially beneficial to each trading country even in the context of public goods.     

Measuring absorptive capacity constraints to foreign aid

To assist with progress towards the United Nations Millennium Development Goals (MDGs) in developing countries, the international community is scaling-up foreign aid to record levels. Concurrently, there are concerns that additional aid will not be used effectively due to a problem of absorptive capacity in recipient countries. Empirical studies lend support to these concerns with many finding that there are diminishing returns to foreign aid. This paper reviews the extensive aid effectiveness literature to identify the various dimensions of absorptive capacity. It proceeds by devising a composite index of absorptive capacity for individual recipient countries which can assist policymakers in guiding the allocation of their aid. The relevance of the index is confirmed through its employment in a standard empirical model of aid effectiveness. The paper highlights the developing countries that currently receive high levels of aid relative to their estimated level of absorptive capacity.     

Stages of diversification in a neoclassical world

Recent research has documented a U-shaped industrial concentration curve over an economy’s development path. How far can neoclassical trade theory take us in explaining this pattern? We estimate the production side of the Heckscher–Ohlin model using industry data on 44 developed and developing countries for the period 1976–2000. Decomposing the implied changes in industrial concentration over time shows that at least one third of these changes seems to be explained by a Rybczynski effect. This result suggests that capital accumulation led poor countries to diversify their industrial production, while rich countries made their production more concentrated in highly capital-intensive industries.     

Walrasian General Equilibrium Allocations and Dynamics in Two-Sector Growth Models

This paper analyzes and solves miniature Walrasian general equilibrium systems of momentary and moving equilibria. The Walrasian framework encompasses the fundamental neoclassical and classical two‐sector growth models; the families of solutions of steady‐state and persistent growth per capita in various competitive two‐sector economies are parametrically characterized. Moreover, the endogenous behavior of relative prices and the sectoral allocation of primary factors are analyzed in detail. The technology parameters of the capital good industry are decisive for obtaining long‐run per capita growth in closed (global) economies. A review of the literature complements the theorems on the general equilibrium allocations, dynamic systems, and the time paths of Walrasian two‐sector economies.     

Are external shocks responsible for the instability of output in low-income countries?

External shocks, such as commodity price fluctuations, natural disasters, and the role of the international economy, are often blamed for the poor economic performance of low-income countries. This paper quantifies the impact of these different external shocks using a panel vector auto-regression approach and determines their contributions to output volatility in low-income countries. We find that they can only explain a small fraction of the output variance of a typical low-income country. Other factors, most likely internal causes, are the main source of fluctuations. From a quantitative perspective, the output effect of external shocks is typically small in absolute terms, but significant relative to the historic performance of these countries.     

Constitutional protection of economic rights: The Swiss and U.S. experience in comparison

This paper analyzes the contribution of the Swiss and the U.S. Constitution to protect economic liberties, and compares the different strategies that both constitutions rely on to achieve this goal. Pertinent provisions in the Swiss Constitution are rather precise but relatively easy to change, whereas the U.S. Constitution is characterized by vaguely formulated constraints that are difficult to amend formally and that are interpreted by the Supreme Court. Nevertheless, the substantial constitutional changes that did occur in both countries seem to have followed strikingly similar patterns: Initially, regional integration through reciprocal market opening within both countries facilitated the constitutional protection of economic liberties. Subsequently, the constitutional protection of economic liberties eroded in both countries, especially against federal legislation, due to changes in the interpretation of the constitution through the courts, or by formal amendment. Lastly, both constitutions were not immune against sudden demands by special interest groups that were being raised during times of crisis or war. I wish to thank Beat Blankart, Ludger Schuknecht and Barry Weingast for helpful comments.     

Does international mobility of high-skilled workers aggravate between-country inequality?

This paper analyzes the interaction of international migration of high-skilled labor and relative wage income between source and destination economies of expatriates. We develop an overlapping-generations model with increasing returns which suggests that international integration of the market for skilled labor aggravates between-country inequality by harming those which are source economies to begin with while benefiting host economies. The result is robust to allowing governments to optimally adjust productivity-enhancing investments which could potentially attenuate brain drain. Optimal public investment tends to decrease in response to higher emigration.     

Does membership in international organizations increase governments’ credibility? Testing the effects of delegating powers

This paper analyzes whether nation-state governments can increase their credibility by becoming members of international organizations. It is hypothesized that the degree of delegation to international organizations can improve the credibility of nation-state governments. This hypothesis is tested by introducing three new indicators for international delegation. On the basis of panel data for up to 136 countries and the time period from 1984 to 2004, membership in international organizations is significantly and robustly linked with better credibility, here proxied for by country risk ratings.     

A century of economic growth in Latin America

This paper makes a contribution to the study of economic growth in developing countries by analyzing the six largest Latin American economies over 105 years within a two-equation framework. Confirming previous findings, physical and human capital prove to be key determinants of GDP per head growth. However, a more controversial result is an overall negative conditional correlation between trade openness and GDP per head growth — though openness has a positive link via investment. The evidence also shows that macroeconomic instability has been a drag on long-term growth in the region.
