We analyze the distribution and concentration of market incomes in Germany in the period 1992 to 2001 on the basis of an integrated data set of individual tax returns and the German Socio-Economic Panel. The unique feature of this integrated data set is that it encompasses the whole spectrum of...

What shapes the optimal degree of progressivity of the tax and transfer system? On the one hand, a progressive tax system can counteract inequality in initial conditions and substitute for imperfect private insurance against idiosyncratic earnings risk. At the same time, progressivity reduces...

Within the context of the neoclassical growth model I investigate the implications of (initial) endowment inequality when the rich have a higher marginal savings rate than the poor. More unequal societies grow faster in the transition process, and therefore exhibit a higher speed of convergence....

It is shown that if social welfare is the sum of logaritmic utility function, the optimal income distribution and the welfare effect of any income redistribution is independet of the equivalence scales. In optimum all households have the same per capita income. Based on this observation it is...

With address to developing countries, this paper derives some formulae for the optimal price structure for publicly provided private goods. A general equilibrium model is examined, which makes it possible to incorporate features like distributional social objectives and public profit constraints...

The objective of this research is to document and to explain trends in inequality in 20th century France. Data from income tax returns (1915-98), wage tax returns (1919-98) and inheritance tax returns (1902-94), is used in order to compute fully homogeneous, yearly estimates of income...

This Paper presents data on the evolution of top incomes and wages from 1956 to 2000 in India using individual tax returns data. Our data shows that the shares of the top 0.01%, the top 0.1% and the top 1% in total income shrank very substantially until the early-to-mid 1980s, but then went back...

This Paper examines the process of development from an epoch of Malthusian stagnation to a state of sustained economic growth. The analysis focuses on recently advanced unified growth theories that capture the intricate evolution of income per capita, technology, and population over the course...

Using tariffs as a measure of openness, this paper finds consistent evidence that the conditional effects of trade liberalization on inequality are correlated with relative factor endowments. Trade liberalization is associated with increases in inequality in countries well-endowed in highly...

We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated goods. Each research project generates a new variety of the differentiated...
