We study the effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit market, the...

This paper studies a complete-market version of the neoclassical growth model, where agents face idiosyncratic shocks to eearnings. We show that if agents possess identical preferences of either the CRRA or the addilog type, then the heterogeneous-agent economy behaves as if there was a...

This paper first establishes the empirical fact that over the last quarter of the 20th century, the average weekly hours worked increased for workers in the highest wage quintile while it decreased for the ones at the lowest. In 1976, a worker in the lowest quintile worked 2.8 hours more per...

Augmenting a standard Bewley model with an entrepreneurial sector and occupational heterogeneity allows us to study important channels through which fiscal policies affect aggregate variables, factor prices, wealth distribution and welfare. To disentangle the forces involved, we consider...

This paper explores the implications of economic and political inequality for the comovement of government purchases with macroeconomic fluctuations. We set up and compute a heterogeneous-agent neoclassical growth model, where households value government purchases which are financed by income...

We study asset-tested unemployment insurance in an incomplete markets model with moral hazard during job search. Optimal asset testing is weak and yields negligible welfare gains. The optimal replacement rate of an unemployed worker with zero liquidity is 9 percentage points higher than that of...

This paper presents an analysis of the trends in inequality across income, earnings and consumption in Britain since 1978. It documents the episodic nature of inequality growth over this period largely dominated by the inequality 'boom' in earnings inequality of the 1980s. It builds a consistent...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...

This paper considers the long-run distribution of capital holdings in a model with complete asset markets and progressive taxation. Households are assumed to be heterogeneous in their labor market productivity. We show that this model is capable of producing a nondegenerate determinate wealth...
