Public expenditure policy, together with efforts to raise revenue,is at the core of efficient and equitable adjustment. Public expenditureproductivity has critical implications for fiscal adjustment, particularly as the competition for limited public resources intensifies.By providing a framework for defining and analyzing public expenditureproductivity and unproductive expenditures, this pamphlet discusseshow economic policymakers may approach these issues.

This paper examines the empirical evidence on the contribution that government and, in particular, capital expenditure make to the growth performance of a sample of developing countries. Using the Denison growth accounting approach, this study finds that social expenditures may have a significant impact on growth in the short run, but infrastructure expenditures may have little influence. While current expenditures for directly productive purposes may exert a positive influence, capital expenditure in these sectors appears to exert a negative influence. Experiments with other explanatory variables confirm the importance of the growth of exports to the overall growth rate.

Public Expenditures, Growth, and Poverty assesses the efficacy of poverty reduction programs in Latin America, Africa, and Asia by synthesizing studies conducted by the International Food Policy Research Institute over the past ten years. Overall, the studies find that investments in agricultural research, infrastructure, and human capital are beneficial in the long term, while food aid and poverty reduction programs have little utility beyond immediately abating hunger and generating short-run income effects. The book develops a conceptual framework for analyzing public expenditures and their short- and long-run impact on poverty through various channels. It surveys spending trends and analyzes the effect of growing public investment on urban and rural poverty through case studies of India, China, Thailand, and Uganda. And it highlights the advantages of directing spending toward public works programs that engage impoverished peoples rather than using the limited aid money on food subsidies and other passive donations. Featuring discussions about the roles of various social safety net programs and a chapter devoted solely to the vexing poverty in sub-Saharan Africa, Public Expenditures, Growth, and Poverty will aid policy makers and encourage further, more analytic study of worldwide poverty reduction programs.

This paper demonstrates that high and rising corruption increases income inequality and poverty by reducing economic growth, the progressivity of the tax system, the level and effectiveness of social spending, and the formation of human capital, and by perpetuating an unequal distribution of asset ownership and unequal access to education. These findings hold for countries with different growth experiences, at different stages of development, and using various indices of corruption. An important implication of these results is that policies that reduce corruption will also lower income inequality and poverty.

Is there a tradeoff between raising growth and reducing inequality and poverty? This paper reviews the theoretical and empirical literature on the complex links between growth, inequality, and poverty, with causation going in both directions. The evidence suggests that growth can be effective in reducing poverty, but its impact on inequality is ambiguous and depends on the underlying sources of growth. The impact of poverty and inequality on growth is likewise ambiguous, as several channels mediate the relationship. But most plausible mechanisms suggest that poverty and inequality reduce growth, at least in the long run. Policies play a role in shaping these relationships and those designed to improve equality of opportunity can simultaneously improve inclusiveness and growth.
