This paper shows how to derive a complete set of optimality conditions characterising the solution to a dynamic optimal income tax problem in the spirit of Mirrlees (1971), under the assumption that a 'first-order' approach to incentive compatibility is valid.  The method relies on constructing...

This paper examines how wealth accumulation and risk sharing affect the evolution of inequality over time. We first assume risk sharing away and examine how inequality evolves over time when agents accumulate an asset. If asset accumulation is unbounded and the asset yields a positive return,...

This paper analyses the factors that give rise to the existence of the informal economy and how it evolves over time.  Using an occupational-choice model the paper shows that at early stages of development, informal and formal markets coexist, but in the long-run the size of the informal...

Previous analyses of the formation and composition of community based organizations (CBOs) have used cross section data.  So, causal inference has been compromised.  We obviate this problem by using data from a quasi-experiment in which villages were formed by government officials selecting...

The study presents recent global evidence on the transformation of economic growth to poverty reduction in developing countries, with emphasis on the role of income inequality.  The focus is on the period since the early-mid-1990s when growth in these countries as a group has been relatively...

The paper presents a model where individuals decide to become workers or entrepreneurs in the presence of capital constraints and where individuals differ in wealth levels.  The model shows that the higher the initial level of inequality in wealth is, the lower the long run aggregate wealth of...

The paper attempts to synthesize the research to date on the contribution of international trade to rising income inequality in the US and to other labour-market developments in other countries. Our basic conclusion is that despite using very different methodologies, on balance most labour and...

Two interesting results are obtained from CASS national household surveys of 1988 and 1995. First, there was a tendency for intra-provincial inequality in both earnings per worker and household income per capita not only to rise in each province but also to converge across provinces. Second,...

The paper analyses two cross-section national household surveys, relating to the years 1988 and 1995, to explain the rise in inequality of income that occured in Chine over those seven years. The Gini coefficient of household income per capita increased from 38 to 45 per cent, i.e. by 1,0...

This paper attempts to analyse certain significant aspects of increasing income inequality in China in the nineteen years since the start of economic system reform. Materials and data used in this paper are partly from a sample survey of rural and urban households made by the income distribution...
