This Paper claims that technical progress induces early retirement of older workers. It supports this claim both theoretically and empirically. We present a model where part of human capital is technology-specific, so that technical progress erodes some existing human capital. This affects...

This Paper proposes a model of endogenous growth where innovating requires both researchers, who produce inventions, and entrepreneurs who implement them. As research and entrepreneurship compete in the allocation of aggregate resources, the relation between growth and research effort is...

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 dynamics of optimal trade policy in a model with costly inter-sectoral adjustment of labour, where migrants pay less than the marginal social cost of migration. If workers have rational expectations, a future tariff has an announcement effect on the current migration decision. If...

This paper uses data from nine tennis Grand Slam tournaments played between 2005 and 2007 to assess whether men and women respond differently to competitive pressure in a setting with large monetary rewards. In particular, it asks whether the quality of the game deteriorates as the stakes become...

This paper evaluates the impact of the widespread use of fixed-term contracts in Spain on firms' TFP, via its effect on workers' effort. We propose a simple analytical framework showing that, under plausible conditions, workers' effort depends positively on their perception (for given level of...

Children's outcomes are strongly correlated with those of their neighbours. The extent to which this is causal is the subject of an extensive literature. An identification problem exists because people with similar characteristics are observed to live in close proximity. Another major difficulty...

This paper offers and tests a theory of training whereby workers do not pay for general training they receive. The crucial ingredient in our model is that the current employer has superior information about the worker’s ability relative to other firms. This informational advantage gives the...

In France, almost one in five 15 year olds lives in a home with at least two children per bedroom. More than 60% of these adolescents have been held back in primary or middle school, a proportion that is more than 20 points higher than it is on average for adolescents of the same age. This Paper...

The paper contains a thorough review of explanations for the weak British growth performance of the 1950s through the 1970s and an assessment of the long-term implications of the 1980s attempt to escape from relative decline. The analysis draws on recent work in growth theory and places...
