Public expenditure distribution,voting, and growth

In this paper, we study why the misallocation of resources across different productive sectors tends to persist over time. To this end, we propose a general equilibrium model that delivers two structural relations. On one hand, the public expenditure distribution influences the future sectoral composition of the economy. On the other hand, the distribution of vested interests across sectors determines public policy decisions. The model predicts that different initial sectoral compositions entail different future streams of public expenditure and therefore different development paths.     

Infant mortality,relative income and public policy

Do health outcomes depend on relative income as well as on an individual's absolute level of income? We use infant mortality as a health status indicator and find a significant and positive link between infant mortality and income inequality using cross-national data for 93 countries. Holding constant the income of each of the three poorest quintiles of a country's population, we find that an increase in the income of the upper 20% of the income distribution is associated with higher, not the lower infant mortality. Our results are robust and not just caused by the concave relationship between income and health. The estimates imply a decrease in infant mortality by 1.5% for a one percentage point decrease in the income share of the richest quintile. The overall results are sensitive to public policy: public health care expenditure, educational outcomes, and access to basic sanitation and safe water can explain the inequality–health relationship. Thus, our findings support the hypothesis of public disinvestment in human capital in countries with high income inequality. However, we are not able to determine whether public policy is a confounder or mediator of the relationship between income distribution and health. Relative deprivation caused by the income distance between an individual and the individual's reference group is another possible explanation for a direct effect from income inequality to health.     

Individual welfare,majority voting,and the properties of a linear income tax

A fundamental problem in public finance is the determination of parameters of income tax functions. This paper focuses on this problem in the context of a linear tax function whose parameters are chosen according to majority vote by the taxpayers. The possibility of conflict between high national income and distributional equity is explored and it is found that, even when the distribution of earning power is rightward skew, majority voting does not necessarily lead to the adoption of a tax function which has the average tax rate rising with income.     

Growth, income distribution, and fiscal policy volatility

The relationship between income distribution and economic growth has long been an important economic research subject. Despite substantial evidence on the negative impact on long-term growth of inequality in the literature, however, there is not much consensus on the specific channels through which inequality affects growth. The empirical validity of two most prominent political economy channels - redistributive fiscal spending and taxes, and sociopolitical instability - has recently been challenged. We advance a new political economy channel for the negative link between inequality and growth, a fiscal policy volatility channel, and present strong supporting econometric evidence in a large sample of countries over the period of 1960-2000. Our finding also sheds light on another commonly observed negative relation between macroeconomic volatility and growth. We carefully address the robustness of the results in terms of data, estimation methods, outlier problem, and endogeneity problem that often plague the standard OLS (ordinary least squares) regression.     

Education, corruption, and the distribution of income

We examine how the interaction between education and corruption affects institutional reform and economic development. While corruption reduces average income and education, education increases not only output and hence potential corruption rents, but also produces more informed electorates that better monitor government actions. We find that economies with intermediate levels of education remain in a poverty trap since the level of skills creates sufficient corruption rents but not enough monitoring. Economies with low or high levels of education can escape the poverty trap, and inequality plays a key role in determining whether this occurs through a change in institutions or an expansion of education.     

Age-income profiles,income distribution and transition proportions

This paper presents a model to link age-income profiles, income distribution, and transition proportions. Transition proportions play a central role in the Markov-chain approach to income distribution. This stochastic model is much criticized, but it is shown in the paper that its most attractive characteristic can be maintained, while at the same time integrating it with a micro-economic foundation of age-income profiles. These profiles are inferred from capability development and individual choice. The model also analytically generates an income distribution.     

Capital markets integration, growth and income distribution

The paper considers a two-country model of overlapping generation heterogenous economies with intergenerational transfers carried out in the form of bequest and investment in human capital. We examine in competitive equilibrium the transitory and long-run effects of capital markets integration. First, we explore how the regime of public education affects the dynamics of the integrated economy. Second, we study the effects of capital markets integration, in equilibrium, on the intragenerational income distribution in both the host and investing country.     

Tax progressivity, income distribution and tax non-compliance

This article examines the determinants of tax non-compliance when we recognise the existence of an imperfectly competitive “tax advice” industry supplying schemes which help taxpayers reduce their tax liability. We apply a traditional industrial organisation framework to model the behaviour of this industry. This tells us that an important factor determining the equilibrium price and hence, the level of non-compliance, is the convexity of the demand schedule. We show that in this context, this convexity is affected by the distribution of pre-tax income, the progressivity of the tax-schedule and the way in which monitoring and penalties vary with income. It is shown that lower pre-tax income inequality as well as a less progressive tax code may cause more tax minimisation activities. Therefore, the frequently advocated policy of reducing the highest tax rate may fail as a policy directed at improving tax discipline. One way of offsetting the possible harm to tax compliance from a less progressive tax could be an adjustment of the penalty and monitoring functions.     

Fiscal policy,growth, income distribution and sociopolitical instability

This paper identifies the fiscal instruments that governments can use to promote economic growth when sociopolitical instability (SPI) is present. We show that fiscal policy that takes into account income distribution and SPI transforms a neoclassical growth model into one with both endogenous growth and a poverty trap. Under these circumstances, the growth rate of the economy depends upon SPI, fiscal policy and income distribution. The baseline level of SPI determines an economy's ability to grow. If SPI is high, the economy remains in a poverty trap even if fiscal policy instruments are set appropriately.     

Endogenous growth and income distribution

A theory of endogenous growth is based on an investment possibility function, relating the growth rate of output to the ratio of gross investment to output and the growth rate of employment as formulated originally by M. F. Scott. Consumers maximize an intertemporal utility function and producers maximize the value of the firm. The long-run rate of growth depends on consumer preferences, the exogenous growth of labor supply and the tax rate on output. The functional distribution of income is determined along with the investment ratio in the steady state. Labor market imperfections and real wage inertia induce transition processes, which are relevant for medium term growth.We are indebted to Olivier Blanchard, Casper van Ewijk, Frederick van der Ploeg, Anton van Schaik, Maurice Scott, Jacques Smulders, and two anonymous referees for their valuable comments on an earlier version.

Brain drain and income distribution

In a context in which increased income inequality has raised much concern, and skilled workers move easily across countries, an important question arises: how does the brain drain affect income distribution in the source economy? We address this question and introduce two contributions to the literature on brain drain. First, we present and solve a simple stylized model to study whether and, if so, how the brain drain affects the distribution of income, in a context in which higher education is publicly financed with general taxes. Second, we explore empirically the effect of an increase in skilled emigration on income distribution. A key prediction of our theoretical model is the existence of a non-monotonic relationship between income inequality and emigration of skilled workers. Our empirical data confirm this result, showing a statistically significant inverse U-shaped form.     

Growth, income distribution and well-being in transition countries

We apply several well-being measures that combine average income with a measure of inequality to international and intertemporal comparisons of well-being in transition countries. Our well-being measures drastically change the impression of levels and changes in well-being compared to a traditional reliance on income measures. Due to low inequality and moderate income levels, socialist countries enjoyed relatively high levels of economic well-being. In the transition process, rising inequality and falling incomes have led to a dramatic absolute decline in well-being and a considerable drop in relative well-being vis-à-vis non-transition countries. We also find a close correlation between income losses and inequality increases. While the transition has been successful in expanding political and civil rights, our indicators suggest that most transition countries are still below the level of economic well-being of the late 1980s.

Dynamics of income distribution

In this paper, we have obtained closed-form solutions in Cass-Koopmans growth models with heterogeneous agents. The relationship between the form of the production function and the dynamics of income distribution is made explicit. We then use this relationship to determine what production structure is simultaneously consistent with facts on growth and income inequality. Our empirical findings give support to models with decreasing returns in the reproducible factor. JEL Classification: D3, O1, O4
Dans ce mémoire, les auteurs obtiennent des solutions pour des modèles de croissance à la Cass-Koopmans dans le cas où les agents sont hétérogènes. On explicite la relation entre la forme de la fonction de production et la dynamique de la répartition des revenus. On utilise alors cette relation pour déterminer quelle structure de production est arrimée aux faits connus à la fois quant à la croissance économique et à la répartition des revenus. Les résultats empiriques supportent les modèles où les rendements sur les acteurs de production reproductibles sont décroissants.     

Logistic regression and world income distribution

Using logistic regression, this paper studies the relationship between the high and nonhigh income countries and a set of indicators of human progress and economic growth. The results show that expenditure on education is the single most relevant factor helping economies to move in the direction of high income countries.     

Models of employment and income distribution

A compact form of the Taylor/Lysy model is presented. It consists of the commodity and factor price frontiers, the saving-investment equilibrium condition and the neoclassical relationship between relative factor prices and the capital intensity. Such compact form is underdetermined. Different ‘closure rules’ give rise to different equilibria, each with its own comparative static properties. The models resulting from a few simple ‘closure rules’ are examined, starting with the full employment, flexible price model, with accumulation of capital determined by available savings. In all cases, capital is fully utilized and financial assets are ignored.     

Selfishness versus public ‘regardingness’ in voting behavior

The selfishness hypothesis in voting behavior is formalized and tested. For the first time individual net benefits from a bond proposal, computed using the median voter model, are used to explain voting behavior. It was found that taxpayers in general voted according to their self- interest as defined by net benefits. However, high income groups voted in favor of proposals that would have redistributed income to the poor. Their behavior is consistent with either the public ‘regardingness’ hypothesis or with an extension of the selfishness hypothesis which includes real estate speculation.     

Public goods,taxation, and the distribution of income over time

With given fiscal and collective choice institutions, the provision and concomitant financing of a public good affect individuals' saving decisions and, hence, may affect the course of the income distribution over time. This paper focuses on this problem for the case of a constitutional democracy in which the major fiscal institution is a set of fixed tax shares and the collective choice mechanism is simple majority voting. The redistributive aspects, rather than the equity aspects, of alternative tax structures are explored.
