Using data from the Consumer Expenditure Survey we first document that the recent increase in income inequality in the US has not been accompanied by a corresponding rise in consumption inequality. Much of this divergence is due to different trends in within-group inequality, which has increased...

This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex-ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex-post. In any given period, after having observed her income, the agent...

In this paper we first document inequality trends in wages, hours worked, earnings, consumption, and wealth for Germany from the last twenty years. We generally find that inequality was relatively stable in West Germany until the German unification (which happened politically in 1990 and in our...

In this paper we argue that it might not be such a bad idea to tax capital income in the long run. We address this question in an environment in which individuals are finitely lived and face uninsurable idiosyncratic labor income risk. In choosing a tax system a benevolent planner trades off...

This paper deals with the macroeconomic effects of government guarantees on debt issued by Government-Sponsored Enterprises. We set up an economy with a housing and mortgage market where the government provides banks with insurance against aggregate shocks to mortgage default risk. We then study...

In this paper we investigate the positive and normative consequences of child-labour restrictions for economic aggregates and welfare. We argue that even though the laissez-faire equilibrium may be inefficient, there are usually better policies to cure these inefficiencies than the imposition of...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

This paper employs a multi-country large scale Overlapping Generations model with uninsurable labour productivity and mortality risk to quantify the impact of the demographic transition towards an older population in industrialized countries on world-wide rates of return, international capital...
