In May 1991, 15,000 Ethiopian Jews were brought to Israel in an overnight airlift and sorted in a haphazard and essentially random fashion to absorption centres across the country. This quasi-random assignment produced a natural experiment whereby the initial schooling environment of Ethiopian...

This paper discusses how employment vouchers should depend on age in a simple overlapping generations model in which workers are either young or old. We find that young workers should receive higher vouchers as displacement of the old rises and as the deadweight loss from providing vouchers to...

This Paper studies the internal commitment mechanisms or ‘personal rules’ (diets, exercise regimens, resolutions, moral or religious precepts, etc.) through which people seek to achieve self-control. Our theory is based on the idea of self-reputation over one’s willpower, which potentially...

This paper explores the optimal design of subsidies for hiring unemployed workers (‘employment vouchers’ for short) in the context of a simple macroeconomic model of the labour market. Focusing on the short-term and long-term effects of the vouchers on employment and unemployment, the...
