The Distributional Effects Of Public Expenditure

It is commonly agreed that economic policies, including budgetary policies, can have potentially strong distributional effects. Traditional economic analysis held that economic policies affected the income distribution primarily through their impact on the rate of growth. More recently, it has come to be recognized that qualitative aspects of economic growth are probably more important than the rate of growth itself. While recent research has confirmed the potential role of expenditure policies as a redistributive tool, it has also shown that redistribution does not necessarily have to come at the expense of economic growth and efficiency. Although there are substantial analytical and technical problems to be faced in the design of equitable and cost-effective public expenditure programs, unfavorable distributional outcomes of these programs can usually be traced more to political and institutional pressures than to purely technical factors.

This book focuses on the distributional consequences of the public sector and examines and documents, theoretically and empirically, the effects of government spending and taxation on personal distribution, and includes chapters investigating the relationship between the public sector and functional distribution of national income.

We construct unanticipated government spending shocks for 103 developing countries from 1990 to 2015 and study their effects on income distribution. We find that unanticipated fiscal consolidations lead to a long-lasting increase in income inequality, while fiscal expansions lower inequality. The results are robust to several measures of income distribution and size of the fiscal shocks, to an alternative identification strategy, across expansions and recessions and across country groups (low-income countries versus emerging markets). An additional contribution of the paper is the computation of the medium-term inequality multiplier. This is on average about 1 in our sample, meaning that a cumulative decrease in government spending of 1 percent of GDP over 5 years is associated with a cumulative increase in the Gini coefficient over the same period of about 1 percentage point. The multiplier is larger for total government expenditure than for public investment and consumption (with the former having larger effect), likely due to the redistributive role of transfers. Finally, we find that (unanticipated) fiscal consolidations lead to an increase in poverty.

This paper examines the methodological issues arising in the measurement of the distributional impact of tax and expenditure policies, with emphasis on the problems related to the measurement of the impact of adjustment programs on the welfare of the poor. Both conceptual and empirical considerations suggest that public expenditures are a more potent instrument for distributional purposes than taxes but are also more difficult to analyze and evaluate. The paper concludes that more research is needed toward a better measurement of expenditure benefits.

In all highly industrialized countries public expenditures are a substantial and growing share of total economic activity. The authors integrate normative and positive theory and empirical analysis of public expenditure, concentrating on the optimal provision of public goods and the estimation of their costs and effects. This volume emphasizes the techniques that are available for reaching collective decisions about the provision of public goods and stresses the importance of income distribution and intergovernmental fiscal relations. In a mixed economy, where the public sector is growing faster than the private sector, the nature of public expenditures must be closely evaluated and studied. This book is designed to focus on and delineate controversies about public expenditure--to define what it is, analyze its function, show how it operates, and finally to evaluate research on this important subject.The book considers the theories of leading economists (Kenneth Arrow, Lionel Robbins, Carl Shoup, James Buchanan, Paul Samuelson, Richard Musgrave, and others) in arriving at a clear statement of theory in its application to operational problems. Appropriate attention is paid to current techniques such as program budgeting, cost-benefit analysis, and the analysis of the determinants of public expenditure. The book is unique in its emphasis on the integration and critique of contemporary theories of public expenditure, of distributional concerns, and of the political framework of public expenditure decisions. It provides a necessary resource for professional economists required to deal with public expenditure problems in research or practice.

The World Bank has partnered with the Commitment to Equity Institute at Tulane University to implement their diagnostic tool—the Commitment to Equity (CEQ) Assessment—designed to assess how taxation and public expenditures affect income inequality, poverty, and different economic groups. The approach relies on comprehensive fiscal incidence analysis, which measures the contribution of each individual intervention to poverty and inequality reduction as well as the combined impact of taxes and social spending. The CEQ Assessment provide an evidence base upon which alternative reform options can be analyzed. The use of a common methodology makes the results comparable across countries. This volume presents eight country studies that examine the distributional effects of individual programs and policy measures—and the net effect of each country’s mix of policies and programs. These case studies were produced in the context of Bank policy dialogue and have since been used to propose alternative reform options.

Monograph on comparison of income distribution trends, adjusted for taxes and public expenditure, in the USA for the years 1950, 1961 and 1970 - presents alternative definitions, empirical methodology and results (gini concentration ratios and lorenz curves), and finds no significant change in the dispersion of final income and that the overall tax system has drifted from progressive to slightly regressive, which in turn, has been offset by social security and other programmes. Bibliography pp. 133 to 139 and graphs.
