This paper analyzes the extent of income inequality from a global perspective, its drivers, and what to do about it. The drivers of inequality vary widely amongst countries, with some common drivers being the skill premium associated with technical change and globalization, weakening protection for labor, and lack of financial inclusion in developing countries. We find that increasing the income share of the poor and the middle class actually increases growth while a rising income share of the top 20 percent results in lower growth—that is, when the rich get richer, benefits do not trickle down. This suggests that policies need to be country specific but should focus on raising the income share of the poor, and ensuring there is no hollowing out of the middle class. To tackle inequality, financial inclusion is imperative in emerging and developing countries while in advanced economies, policies should focus on raising human capital and skills and making tax systems more progressive.

Deals with income distribution methods and their economic applications.

Adjustment programs will fail when they do not recognize the interdependence of the three criteria of efficiency, welfare, and political feasibility. These programs must be tailored to both the political and economic environments of each country.

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.

Distributional issues may not have always been among the main concerns of the economic profession. Today, in the beginning of the 2000s, the position is different. During the last quarter of a century, economic growth proved to be unsteady and rather slow on average. The situation of those at the bottom ceased to improve regularly as in the preceding fast growth and full-employment period. Europe has seen prolonged unemployment and there has been widening wage dispersion in a number of OECD countries. Rising affluence in rich countries coexists, in a number of such countries, with the persistence of poverty. As a consequence, it is difficult nowadays to think of an issue ranking high in the public economic debate without some strong explicit distributive implications. Monetary policy, fiscal policy, taxes, monetary or trade union, privatisation, price and competition regulation, the future of the Welfare State are all issues which are now often perceived as conflictual because of their strong redistributive content. Economists have responded quickly to the renewed general interest in distribution, and the contents of this Handbook are very different from those which would have been included had it been written ten or twenty years ago. It has now become common to have income distribution variables playing a pivotal role in economic models. The recent interest in the relationship between growth and distribution is a good example of this. The surge of political economy in the contemporary literature is also a route by which distribution is coming to re-occupy the place it deserves. Within economics itself, the development of models of imperfect information and informational asymmetries have not only provided a means of resolving the puzzle as to why identical workers get paid different amounts, but have also caused reconsideration of the efficiency of market outcomes. These models indicate that there may not necessarily be an efficiency/equity trade-off; it may be possible to make progress on both fronts. The introduction and subsequent 14 chapters of this Handbook cover in detail all these new developments, insisting at the same time on how they tie with the previous literature on income distribution. The overall perspective is intentionally broad. As with landscapes, adopting various points of view on a given issue may often be the only way of perceiving its essence or reality. Accordingly, income distribution issues in the various chapters of this volume are considered under their theoretical or their empirical side, under a normative or a positive angle, in connection with redistribution policy, in a micro or macro-economic context, in different institutional settings, at various point of space, in a historical or contemporaneous perspective. Specialized readers will go directly to the chapter dealing with the issue or using the approach they are interested in. For them, this Handbook will be a clear and sure reference. To more patient readers who will go through various chapters of this volume, this Handbook should provide the multi-faceted view that seems necessary for a deep understanding of most issues in the field of distribution.

World Bank Technical Paper No. 394. Joint Forest Management (JFM) has emerged as an important intervention in the management of Indias forest resources. This report sets out an analytical method for examining the costs and benefits of JFM arrangements. Two pilot case studies in which the method was used demonstrate interesting outcomes regarding incentives for various groups to participate. The main objective of this study is to develop a better understanding of the incentives for communities to participate in JFM.
