The Composition of Government Expenditure: Economic Conditions and Preferences

This paper examines the question of why the composition of government expenditure differs among democratic countries and to what extent it may be explained by differences in economic conditions or preferences. A simple overlapping generations model, which allows for a range of relevant factors, is constructed to examine the division of expenditure on public goods and a transfer payment under majority voting. The model yields a closed-form solution for the majority choice of the expenditure ratio. An empirical examination suggests that income inequalities play a minor role while different preferences for public goods reflecting cultural differences across countries may play an important role in accounting for the substantial variations in expenditure patterns.

The Composition of Government Expenditure with Alternative Choice Mechanisms

This paper investigates the choice of the composition of government expenditure using both positive and normative approaches. The former involves aggregation over selfish voters (simple majority voting and stochastic voting are examined), while the latter involves the choice by a single disinterested individual (considered to maximise a social welfare function). The approach allows direct comparisons of the choice mechanisms. The structures examined include a transfer payment combined with a pure public good, and a transfer payment with tax-financed education. Explicit solutions are obtained for the choice of expenditure components, and these are shown to depend on the proportional difference between the arithmetic mean and another measure of location of incomes, where the latter depends on the choice mechanism. In each case the expenditure composition depends on an inequality measure defined in terms of the proportional difference between a measure of location of the income distribution and the arithmetic mean, where the location measure depends on the decision mechanism.

Inequality Aversion and the Optimal Composition of Government Expenditure

This paper examines the choice of government expenditure on public goods and transfer payments, in the form of a pension, in an overlapping generations model. Government expenditure is tax-financed on a pay-asyou- go basis. A utilitarian judge chooses expenditures to maximize a social welfare function. The nonlinear solution is found to involve the ratio of a welfare-weighted average income, which depends on the inequality aversion of the judge, to arithmetic mean income. An approximation for this ratio is found which produces explicit solutions for the optimal composition. The result is used to obtain an indication of ‘implicit’ inequality aversion for a range of countries.

Modelling the Composition of Government Expenditure

The composition of government expenditure varies considerably across countries. The aim of this book is to explore the choice of expenditure using a range of modelling approaches.

Public–private mix of health expenditure: A political economy and quantitative analysis

This paper constructs a simple model to examine decisions on public and private health spending under majority voting. In the model, agents with heterogeneous incomes choose how much to consume and spend on health care and vote for public health expenditure. The health status of an agent is determined by a CES composite of public and private health expenditure. The existence and uniqueness of the voting equilibrium are established. A quantitative exercise reveals the importance of the relative effectiveness of public and private health expenditure and their substitutability in determining the public-private mix of health expenditure and in accounting for the observed differences across a sample of 22 advanced democratic countries.

What has driven the great fertility decline in developing countries since 1960

Abstract Several developing countries are currently experiencing a significant fertility decline, however, academic economists have paid little attention to this transition. This paper seeks to explain the fertility transition by infant mortality, urbanisation, income, culture and educational attainment of females and males using annual data for 92 developing countries over the period 1960–2014. External instruments are used to deal with endogeneity. The results suggest that increasing per capita income, improved female education and increasing secularisation have been important determinants for declining fertility in the developing world.

THE OPTIMAL DIVISION OF GOVERNMENT EXPENDITURE BETWEEN PUBLIC GOODS AND TRANSFER PAYMENTS

This paper examines the optimal ratio of transfer payments to expenditure on public goods, for a given income tax rate. The transfer payment is then determined by the governments budget constraint. The optimal ratio of transfers to public good expenditure per person is expressed as a function of the ratio of the median to the arithmetic mean wage, and of the tax rate. Reductions in the skewness of the wage rate distribution are associated with reductions in transfer payments relative to public goods expenditure, at a decreasing rate. Furthermore, increases in the tax rate, from relatively low levels, are associated with increases in the relative importance of transfer payments. But beyond a certain level, further tax rate increases are associated with a lower ratio of transfers to public goods, because of adverse incentive effects.
