Brain-drain taxes for non-benevolent governments

This paper investigates the welfare effects of brain-drain taxes levied by non-benevolent governments, whereby a country collects a tax from skilled emigrants but potentially wastes a sizable portion of the revenue. Using a model in which taxes are chosen to maximize expected political rents, I show that the availability of a brain-drain tax increases a weighted sum of citizen utilities. However, the government's optimal brain-drain tax is found to be higher than the level that maximizes this weighted sum. In another model, a brain-drain tax is found to be desirable when governments use public good expenditures to compete for mobile residents.     

Agriculture production versus biodiversity protection: The impact of North-South unconditional transfers

The purpose of this paper is to explore whether international income transfers can improve or worsen the global level of biodiversity and global social welfare by changing the relative contributions to biodiversity protection and to agricultural production. Because of the public good nature of biodiversity, Warr's neutrality theorem suggests that such transfers may have no effects at all (Warr, 1983). A model is developed, based on the simplifying assumption that northern countries have little biodiversity whereas southern countries are endowed with natural capital in the form of (generally unspoilt) biodiversity-rich land. Southern countries allocate optimally land and capital to two competing productive activities, agriculture and eco-tourism. When transfers are organized from the North to the South, we show that Warr's neutrality theorem collapses. Transfers can either reduce or increase the natural capital in the South, depending on some empirically verifiable hypotheses concerning the characteristics of the eco-tourism and agricultural production functions. In addition, we demonstrate that welfare improvements can be obtained even with reductions in the level of biodiversity.     

On representative social capital

This paper analyzes the behavior of subjects randomly drawn from the Dutch population who reveal their capacity to provide and sustain social capital by their propensity to invest and reward investments in an economic experiment. We find that heterogeneity in behavior is characterized by several asymmetries—men, the young and elderly, and low educated individuals invest relatively less, but reward significantly more investments. The age effects are found to corroborate existing findings, whereas those of gender and education do not. Higher expected levels of investments by others are found to have a positive and significant effect on own investments. Finally, a laboratory experiment with student subjects is found to provide a lower bound of the population level of social capital.     

Europe as social reality

What is “Europe”? There exist European legal rules, emergent from the institutional structure constructed from the treaties negotiated among the separate nation-states over the half-century since World War II. The social reality that is Europe in 1996 remains far removed from the social reality that is the United States, where individuals are directly subject to federal laws as well as those laws promulgated through the separate states. Europe is not yet a federal union or a federalism, but may qualify as a confederation of nation-states. Europe, as observed, does not correspond to the theorists' model for political federalism. It remains open as to whether or not any approximation to this model will ultimately be realized.     

Ethnic networks and trade: Intensive versus extensive margins

Ethnic networks have been associated with increased international trade, although studies have not differentiated between entry into foreign markets and trade expansion. We find that ethnic networks increase trade on the intensive margin but not on the extensive margin.     

Institutional competition among jurisdictions: An evolutionary approach

The purpose of this paper is to outline an evolutionary approach to the process of competition among institutions. We shall focus, in particular, on two issues: first, the role of the competitive process as a knowledge-creating process; and, second, the issue of what inferences, if any, can be drawn from the nature of this process regarding the desirability of its outcomes. In discussing both issues we will draw a parallel between ordinary market competition and competition in the realm of institutions. Some clarifying comments in order to narrow down what we mean by “evolutionary approach” and “institutional competition” precede the analysis. The authors wish to thank Richard Wagner for helpful criticism.     

The political economy of public health expenditure and wait times in a public‐private mixed health care system

Abstract This paper investigates the determinants of public health expenditure in a public‐private mixed health care system, where a longer wait time for public care is the major difference between public and private sectors. Voter preferences for health care vary according to their age and by income, and public policy choices are part of a multi‐dimensional, competitive political equilibrium. We show how equilibrium public health expenditure and wait times depend on demographics and explain why they are independent of the distributions of income and political influence. We also show that population aging may not always lead to more public health expenditure.     

Profits and politics: Coordinating technology adoption in agriculture

This paper examines the political economy of government-led coordination of economic activity in a simple two-sector model in which individuals' choice of agricultural technology affects industrialization. We demonstrate the existence of multiple equilibria; the economy is either characterized by the use of a traditional agricultural technology and a low level of industrialization or the use of a mechanized technology and a high level of industrialization. Relative to the traditional technology, use of the mechanized technology increases output but leaves some population groups worse off. We show that the distributional implications of choosing the mechanized technology restrict the possibility of Pareto-improving coordination by an elected policy-maker, even when we allow for income redistribution.     

Expressive and Instrumental Voting: The Scylla and Charybdis of Constitutional Political Economy

Brennan and Hamlin [(2002) Constitutional Political Economy 13(4): 299–311] noted that expressive voting still holds at the constitutional phase. The argument, when taken to its necessary conclusion, proves quite problematic for Constitutional Political Economy. Veil mechanisms following Buchanan induce expressive voting at the constitutional phase, removing the normative benefits ascribed to the hypothetical unanimity principle. If the constitution is authored by a small group and the veil is thereby removed, instrumental considerations come to bear and the authors of the constitution establish themselves as Oligarch.     

What determines foreign aid? The donors' perspective

This paper examines the factors affecting the support for foreign aid among voters in donor countries. A simple theoretical model, which considers an endogenous determination of official and private aid flows, relates individual income to aid support and also suggests that government efficiency is an important factor in this regard. The empirical analysis of individual attitudes, based on the World Values Surveys, reveals that satisfaction with own government performance and individual relative income are positively related to the willingness to provide foreign aid. Furthermore, using actual donor country data we find that aid is adversely affected by own government inefficiency.     

Optimal redistribution with unobservable disability: Welfarist versus non-welfarist social objectives

This paper examines the optimal non-linear income and commodity tax when the same labor disutility can receive two alternative interpretations, taste for leisure or disability, but the disability is not readily observable. We compare the optimal policy under alternative social objectives, welfarist and non-welfarist, and conclude that the non-welfarist objective, in which the planner gives a higher weight to the disutility of labor of the disabled individuals, is the only reasonable specification. It has some foundation in the theory of responsibility; further, unlike the other specifications it yields an optimal solution that may involve a lower labor supply requirement from disabled individuals.     

Global terrorism: deterrence versus pre-emption

Abstract .  This paper analyses two anti-terrorism policies when a targeted nation's people and property are in jeopardy at home and abroad. A country's deterrence decision involves both external benefits and costs as the terrorist threat is deflected, while its preemption decision typically gives external benefits when the threat is reduced for all potential targets. With damages limited to home interests, a country will overdeter, while, for globalized terror, a country will underdeter. Pre-emption is usually undersupplied. Leader-follower behaviour is apt to lessen inefficiency for deterrence, but worsen inefficiency for pre-emption, compared with simultaneous-choice equilibrium allocations. Targeted nations can never achieve the proper counterterrorism policy through leadership.     

Child welfare programs and child nutrition: Evidence from a mandated school meal program in India

Utilizing the data I collected on a nationally mandated school meal program in India, I examine the extent to which children benefit from the targeted public transfer. Relying upon built-in randomness in whether a child's 24-hour food consumption recall was for a school or non-school day, I find that the daily nutrient intake of program participants increased substantially by 49% to 100% of the transfers. The results are robust to the potential endogeneity of program placement and individual participation. The findings suggest that for as low a cost as 3 cents per child per school day the scheme reduced the daily protein deficiency of a primary school student by 100%, the calorie deficiency by almost 30% and the daily iron deficiency by nearly 10%. At least in the short-run, therefore, the program had a substantial effect on reducing hunger at school and protein-energy malnutrition.     

Old‐age Social Security versus Forward Intergenerational Public Goods Provision

This paper introduces an overlapping‐generations model with earnings heterogeneity and borrowing constraints. The labour income tax and the allocation of tax revenue between social security and forward intergenerational public goods are determined in a bidimensional majoritarian voting game played by successive generations. The political equilibrium is characterized by an ends‐against‐the‐middle equilibrium where low‐income and high‐income individuals form a coalition in favour of a lower tax rate and less social security while middle‐income individuals favour a higher tax rate and greater social security. Government spending then shifts from social security to public goods provision if higher wage inequality is associated with a borrowing constraint and a high elasticity of marginal utility of youth consumption.     

A spatial analysis of provincial corporate income tax responses: evidence from Canada

Abstract.  Using a model of interdependent tax choices, and accounting for equalization entitlements and general transfers, this paper estimates – making use of a spatial econometric framework – corporate income tax-setting functions for all Canadian provincial governments. The results show that there is a statistically significant positive fiscal interaction among a subset of provinces and between all provinces and the federal government. Provincial corporate income taxes are also found to be negatively related to equalization entitlements, general federal transfers, and the federal corporate income tax. A robustness check on the fiscal relationship between Ontario and Quebec verifies the existence of significant bi-directional fiscal interdependencies. The paper also introduces U.S state corporate income taxes as covariates and examines their interaction with Canadian provinces.     

Public versus private risk sharing

Can public income insurance through progressive income taxation improve the allocation of risk in an economy where private risk sharing is incomplete? The answer depends crucially on the fundamental friction that limits private risk sharing in the first place. If risk sharing is limited because insurance markets are missing for model-exogenous reasons (as in Bewley (1986) [8]) publicly provided risk sharing improves on the allocation of risk. If instead private insurance markets exist but their use is limited by limited enforcement (as in Kehoe and Levine (1993) [23]) then the provision of public insurance interacts with equilibrium private insurance, as, by providing risk sharing, the government affects the value of exclusion from private insurance markets and thus the enforcement mechanism of these contracts. We characterize consumption allocations in an economy with limited enforcement and a continuum of agents facing plausible income risk and tax systems with various degrees of progressivity (public risk sharing). We provide conditions under which more publicly provided insurance actually reduces total insurance for agents (excess crowding-out), or under which more public insurance increases total insurance (partial crowding-out).     

Convergence of numerical solutions for a class of stochastic age-dependent capital system with Markovian switching

Recently, numerical solutions of stochastic differential equations have received a great deal of attention. Numerical approximation schemes are invaluable tools for exploring its properties. In this paper, we introduce a class of stochastic age-dependent (vintage) capital system with Markovian switching, and investigate the convergence of numerical approximation. It is proved that the numerical approximation solutions converge to the analytic solutions of the equations under the given conditions. A numerical example is provided to illustrate the theoretical results.     

Company taxation and tax spillovers: Separate accounting versus formula apportionment

It is observed in the real world that taxes matter for location decisions and that multinationals shift profits by transfer pricing. The US and Canada use so-called formula apportionment (FA) to tax corporate income, and the EU is debating a switch from separate accounting (SA) to FA. This paper develops a theoretical model that compares basic properties of FA to SA. The focal point of the analysis is how changes in tax rates affect capital formation, input choice, and transfer pricing, as well as on spillovers on tax revenue in other countries. The analysis shows that a move from SA to FA will not eliminate such spillovers and will, in cases identified in the paper, actually aggravate them.
