Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

This paper provides a survey of recent growth models that attempt to explain the cross-country diversity in rates of economic growth. It shows that these models can only generate differences in growth rates in the absence of international capital markets. With free international capital mobility...

We develop a simple growth model with imperfect competition in which demand conditions can affect the dynamics of capital accumulation, hindering or enhancing growth. In our model the elasticity of the demand schedule faced by a typical firm depends on the aggregate savings rate. The latter...

How do aggregate wealth-to-income ratios evolve in the long run and why? We address this question using 1970-2010 national balance sheets recently compiled in the top eight developed economies. For the U.S., U.K., Germany, and France, we are able to extend our analysis as far back as 1700. We...

In an overlapping generations model, rents to human capital play a key role in increasing savings. In the absence of such rents, the return to human capital is entirely appropriated by the old and accumulation is entirely determined by the income to fixed factors. If rents are introduced by...

The paper studies how high leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2007 both exhibited a large increase in the income share of the rich, a large increase in leverage for the remainder, and an eventual financial...

We introduce non-homothetic preferences into a general equilibrium model of monopolistic competition and explore the impact of income inequality on the medium-run macroeconomic equilibrium. We find that (i) a sufficiently high extent of inequality divides the economy into mass consumption...

This paper evaluates the prospects for income tax reform in China during the coming decade (with a comparison to India), and argues that such reforms should rank high on the policy agenda in these two countries. Due to high average income growth and sharply rising top income shares during the...

Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...

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...
