In this Paper, we analyse the extent to which market forces create an incentive for cloning human beings. We show that a market for cloning arises if a large enough fraction of the clone's income can be appropriated by its model. Only people with the highest ability are cloned, while people at...

Abstract U.S. fertility rose from a low of 2.27 children for women born in 1908 to a peak of 3.21 children for women born in 1932. It dropped to a new low of 1.74 children for women born in 1949, before stabilizing for subsequent cohorts. We propose a novel explanation for this boom-bust...

In this paper we investigate how fertility decisions respond to unexpected career interruptions, which occur as a consequence of job displacement. Using an event study approach we compare the birth rates of displaced women with those of women unaffected by job loss after establishing the...

Despite the relevance of cognitive and non-cognitive skills for professional success, their formation is not yet fully understood. This study fills part of this gap by analyzing the role of sports club participation, one of the most popular extra-curricular activities, on children’s skill...

Women’s economic emancipation arguably took off in the late 1960s and early 1970s. While ubiquitous, its origins are not well understood. In an influential paper, Goldin and Katz [2002] pointed to the role of unmarried women’s access to the oral contraceptive (the Pill), ushered in by the...

The dynamics of women’s labour supply are examined at a crucial stage of the life-cycle. This paper uses the longitudinal employment history records for 3,893 33-year-old mothers in the 5th sweep of the 1958 National Child Development Study cohort. Models of binary recurrent events are...

Technological change was unskilled-labor-biased during the early Industrial Revolution, but is skill-biased today. This is not embedded in extant unified growth models. We develop a model which can endogenously account for these facts, where factor bias reflects profit maximizing decisions by...

We study the intergenerational transmission of cognitive and non-cognitive abilities between parents and sons, using population-wide enlistment data. Conscripts are evaluated at the same age and with comparable methods across cohorts, and we correct for measurement error bias in fathers’...

We model educational investment, wages and employment status (full-time, part-time or non-participation) in a frictional world in which heterogeneous workers have different productivities, both at home and in the workplace. We investigate the degree to which there might be under-employment and...
