On the existence of lindahl equilibria in economies with a measure space of non-transitive consumers

We present a generalization of Roberts' theorem on the existence of Lindahl equilibria in economies with a measure space of agents. The principal contribution of this paper is methodological. We show that by formulating the problem in what we consider to be its natural infinite dimensional setting, the basic structure of Debreu's proof in the theory of value can be applied. Our proof makes use of functional analysis and relies, in particular, on Artstein's characterization of weak sequential convergence in L₁(μ).     

Physical quality of life index and inter-country inequality

Treating the ‘physical quality of life index’ (PQLI) as a measure of national well-being, Theil's cross-country inequality index is computed and compared with those based on nominal and real GNP per capita. The index based on PQLI seems to understate drastically inter-country inequality, and suggests a pattern of inequality change that appears implausible.     

Bootstrapping for standard errors of instrumental variable estimates

Theil and Finke (1983) used the distance from the equator as an instrumental variable (IV) in the estimation of a cross-country demand system. Here we obtain standard errors of the IV estimates using Efron's (1979) bootstrap technique.     

Formal institutions and subjective well-being: Revisiting the cross-country evidence

A long tradition in economics explores the association between the quality of formal institutions and economic performance. The literature on the relationship between such institutions and happiness is, however, rather limited, and inconclusive. In this paper, we revisit the findings from recent cross-country studies on the institution–happiness association. Our findings suggest that their conclusions are qualitatively rather insensitive to the specific measure of ‘happiness’ used, while the associations between formal institutions and subjective well-being differ among poor and rich countries. Separating different types of institutional quality, we find that in low-income countries the effects of economic–judicial institutions on happiness dominate those of political institutions, while analyses restricted to middle- and high-income countries show strong support for an additional beneficial effect of political institutions. Our results bear important implications that we discuss in the concluding section of the paper.

INFLATION HISTORY AND THE SACRIFICE RATIO: EPISODE-SPECIFIC EVIDENCE

This article examines whether episode-specific analysis can show a negative relationship between inflation and the slope of the Phillips curve that has been found in cross-country analysis. While the relationship between inflation and the Phillips curve slope is widely accepted from cross-country analysis, it has remained unproven in previous episode-specific studies. By defining inflation history as a weighted average of past inflation, this study finds a negative effect of inflation history on the sacrifice ratio, which is what is expected from the cross-country analysis. The negative relationship does not disappear even after including other conventional determinants of the sacrifice ratio. ( JEL E52, E31)     

State and religion

State and religion have historically had an uneasy relationship, at times being close allies, at others harsh adversaries, and at still others largely independent. This paper develops an economic model of this relationship, where the state’s objective is to maximize net tax revenue. Religious goods benefit the state in two ways: first, they provide utility to citizens, thus allowing the state to extract more taxes before running up against citizens’ reservation utility (the point at which they would revolt), and second, they potentially provide legitimacy to the state, thereby lowering the costs of tax collection. If the latter effect is strong enough, the state may find it optimal to take control of religion, either to enhance its legitimizing effect, or to suppress its de-legitimizing effect. Greater competition in the religion market and democratic polity make it less likely for the state to control religion. To evaluate the model’s implications, we use recent cross-country data on the relationship between religion and state, including variables from the “Religion and State Project” and measures coded from the 2001, 2003, and 2005 International Religious Freedom reports. We also examine in more detail some of the paradigmatic cases indicated by the model, presenting various types of evidence from current and historical examples of each case.     

Military Spending, Government Disarray, and Economic Growth: A Cross-Country Empirical Analysis

Recent years have seen a spate of empirical studies that have used cross-country regressions to examine a variety of possible determinants of long-term economic growth. The present study considers an additional, largely overlooked, explanatory variable: military spending. Consistent with Thompson’s (1974) hypothesis that enhanced national defense fosters economic growth by increasing the security of property rights, the military expenditures share of GDP is found to have a statistically significant positive impact on the growth rate of per capita GDP. This result is obtained for two alternative model specifications, a Barro-regression and a LISREL variant of that regression. The LISREL variant is motivated by Sala-i-Martin’s (1994) claim that the impact of government economic policies jointly, rather than extant government policies individually and separately, is "the phenomenon that really matters" for long-term economic growth.     

Individual decisions and group decisions: The fundamental differences

The paper contains a unified development of Arrow's impossibility theorem for rational group decisions, Gibbard and Satterthwaite's impossibility theorem for strategy-proof group decisions, and the close reciprocal relationship that exists between these two theorems.     

Trade, regulations, and income

We examine the relationship between openness and per-capita income using cross-country data from 126 countries. We find that trade leads to a higher standard of living in flexible economies, but not in rigid economies. Business regulation, especially on firm entry, is more important than financial development, higher education, or rule of law as a complementary policy to trade liberalization. Specifically, after controlling for the standard determinants of per-capita income, our results imply that a 1% increase in trade is associated with more than a one-half percent rise in per-capita income in economies that facilitate firm entry, but has no positive income effects in more rigid economies. The findings are consistent with Schumpeterian “creative destruction”, which highlights the importance of new business entry in economic performance, and with previous firm-level studies showing that the beneficial effects of trade liberalization come largely from an intra-sectoral reallocation of resources.     

Social choice and telling the truth

This paper presents a straightforward proof of Gibbard's theorem that any non-manipulable choice rule with at least three outcomes is dictatorial. The proof is similar to proofs of Arrow's impossibility theorem, but does not rely on that theorem. The last part of the paper discusses the relation between Gibbard's and Arrow's theorems. The paper contains no new result, and is intended to make this important area of social choice theory accessible to a wider audience.     

State of the “life span revolution” between 1980 and 2000

Using data for 163 countries, state of the “life span revolution” over the period 1980–2000 is studied in terms of measures of cross-country inequality and through least-squares and quantile-regression estimation of simple convergence models. Four main points are noted. First, dynamics of the cross-country distribution of life expectancy during these 20 years seem markedly different from those for the preceding decades: instead of the sharp “convergence” noted until the 1980s, there is lack of convergence and an indication of “divergence”. Second, the divergence is particularly marked during the 1990s. Third, spread of HIV/AIDS has probably been a significant factor in generating divergence during the 1990s. Fourth, besides the sizable temporal heterogeneity, quantile-regression estimates of convergence models reveal a substantial heterogeneity across the top and the bottom quartiles within each period.     

Balance sheet identity and Walras' Law

The balance sheet identity is interpreted to imply that if n ? 1 of n assets are in stock equilibrium, so is the remaining asset. Under the notion of the end-of-period equilibrium, the following are shown. (1) This interpretation leads to the contradiction that the system does not allow enough independent equilibrium relations to determine uniquely the equilibrium values of its endogenous variables. (2) The balance sheet identity is equivalent to Walras' Law in flow form. Thus, Foley's methodological precept is verified; transforming a period model into its continuous time analogue does not lead to different outcomes from period analysis.     

Income Inequality and Economic Growth: Evidence from American Data

While most cross-country studies find a negative relationship between income inequality and economic growth, studies that use panel data suggest the presence of a positive relationship between inequality and growth. This paper uses a cross-state panel for the United States to assess the relationship between inequality and growth. Using both standard fixed effects and GMM estimations, this paper does not find evidence of a positive relationship between inequality and growth but finds some evidence in support of a negative relationship between inequality and growth. The paper, however, shows that the relationship between inequality and growth is not robust and that small differences in the method used to measure inequality can result in large differences in the estimated relationship between inequality and growth.     

On the mechanism of international technology diffusion for energy technological progress

As a needed methodological complement to the existing large-scale complex policy modelling for energy technology diffusion, this paper contributes to an analytical exposition of the fundamental mechanism of international technology diffusion (ITD) for energy technological progress. We offer two different and complementary perspectives to explore the dynamics of energy technology diffusion and progress. We first develop a Solow-type efficiency-improving model of energy technological progress which is described by improvements in primary energy-augmenting efficiency. We further provide a Romer-type variety-expanding model of energy technological progress which is represented by the expansion of differentiated varieties of primary energy technology blueprints. Analysis based on two different models reaches consistent results: there are potential forces in the world economy – working through ITD – that pull individual countries to advance energy technology, ensuring a cross-country convergence in the growth rates of energy technology in the balanced growth path. While ITD plays a role in a cross-country convergence in technological growth rates, cross-country differences in the efficiency of undertaking indigenous research and the capacity of absorbing foreign technology spillovers would lead to a cross-country divergence in the absolute levels of energy technology.

Convergence or divergence in cross-country growth?

In the traditional empirical convergence literature, a negative coefficient on initial income in a cross-country growth regression is interpreted as evidence of poor countries growing faster than richer ones. A key assumption in this work is that the relationship between initial income and income growth is linear. The linearity assumption is challenged in some new growth theories, and studies adopting an alternative (semi-parametric or nonlinear) econometric methodology provide support for a nonlinear specification. This paper finds evidence for nonlinear convergence. Using semi-parametric estimation we find that convergence occurs among countries with very low and very high initial incomes, suggesting that convergence clubs characterize the cross-country growth process. Our results provide further evidence for multiple-regime steady states.     

On the optimal income taxation: Some further numerical results

Using numerical calculations we show in the optimal income tax model that a realistic value for the elasticity of substitution between consumption and leisure (?=0.5) leads to conclusions different from some of those drawn by Mirrlees (1971) and Atkinson (1973). The marginal tax rates are not so low and the shape of the tax schedule is for a great majority of the population substantially nonlinear. A new feature in our calculations is that both results come out without going to maximin, as done by Atkinson (1973). We study in special cases the locality of the zero limit of the marginal tax rate at the upper end of the ability distribution and we achieve a very definite conclusion: this result is really very local. We also present an interesting approximation result concerning the relationship between the level of the government revenue and the marginal tax rate for individuals with high ability. An important methodological remark analogous to Sen's critique on the ethical measures of inequality is made on the interpretation of optimal income tax calculations.     

Determinants of long-term growth: New results applying robust estimation and extreme bounds analysis

Two important problems exist in cross-country growth studies: outliers and model uncertainty. Employing Sala-i-Martin’s (1997a,b) data set, we first use robust estimation and analyze to what extent outliers influence OLS regressions. We then use both OLS and robust estimation techniques in applying the Extreme Bounds Analysis (EBA) to deal with the problem of model uncertainty. We find that the use of robust estimation affects the list of variables that are significant determinants of economic growth. Also the magnitude of the impact of these variables differs sometimes under the various approaches.First version received: March 2003 / Final version received: June 2004We like to thank two referees for their very helpful comments on a previous version of this paper.

Corruption and the effects of economic freedom

The prediction that economic freedom is beneficial in reducing corruption has not been found to be universally robust in empirical studies. The present work reviews this relationship by using firms' data in a cross-country survey and argues that approaches using aggregated macro data have not been able to explain it appropriately. We model cross-country variations of the microfounded economic freedom–corruption relationship using multilevel models. Additionally, we analyse this relationship by disentangling the determinants for several components of economic freedom because not all areas affect corruption equally. The results show that the extent of the macro-effects on the measures of (micro)economic freedom for corruption, identified by the degree of economic development of a country, can explain why a lack of competition policies and government regulations may yield more corruption. Estimations for Africa and transition economy subsamples confirm our conjectures.
