Adjustment And Income Distribution

This paper presents a structural macro simulation model to quantify the effects of alternative stabilization packages on the distribution of income and wealth. The model combines the explicit microeconomic optimizing behavior characteristic of computable general equilibrium models with asset portfolio behavior of macroeconomic models in Tobin's tradition. In this model there are four main mechanisms by which policy changes affect the distribution of income and wealth. First changes in factor rewards affect directly household income distribution. Second, household real incomes are affected by changes in their respective cost of living indexes. Third, household real incomes are affected by changes in real returns on financial assets since household incomes include income from financial holdings. Fourth, household wealth distribution is affected by capital gains and losses. Simulations with' the model are carried out for a representative economy subject to the interest rate and terms-of-trade shocks of the early 1980s. The simulations suggest a large adverse impact on the distribution of income of a sharp contractionary package. The resulting distributional shifts are likely to endanger the sustainability of the package even though the distribution of income becomes more equal when normal policies are resumed. By contrast, the targeted expenditure cut programs advocated by the critics of contractionary packages result in a much less unequal distribution of income during the adjustment package, even though the distributional improvements of the targeted package are mostly reversed in the post-adjustment period. The simulations support the view that stabilization packages which do not have specific components targeted towards the poor will have a noticeable adverse effect on the distribution of income, which is likely to result in some form of permanent damage for those below the poverty line.

There are a variety of approaches, and country issues and data availability will determine the most practical approach.

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.

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.

Structural adjustment and economic stabilization programmes are alleged in many developing countries to have imposed a high social cost in terms of the distribution of income and the incidence of poverty.; This study develops a framework for selecting appropriate instruments to optimize efficiency and equity in these countries, as well as those in transition to a market economy.

This book looks at the distribution of income and wealth and the effects that this has on the macroeconomy, and vice versa. Is a more equal distribution of income beneficial or harmful for macroeconomic growth, and how does the distribution of wealth evolve in a market economy? Taking stock of results and methods developed in the context of the 1990s revival of growth theory, the authors focus on capital accumulation and long-run growth. They show how rigorous, optimization-based technical tools can be applied, beyond the representative-agent framework of analysis, to account for realistic market imperfections and for political-economic interactions. The treatment is thorough, yet accessible to students and nonspecialist economists, and it offers specialist readers a wide-ranging and innovative treatment of an increasingly important research field. The book follows a single analytical thread through a series of different growth models, allowing readers to appreciate their structure and crucial assumptions. This is particularly useful at a time when the literature on income distribution and growth has developed quickly and in several different directions, becoming difficult to overview.
