Tournaments are designed to enhance participants' effort and productivity. However, ranking near the top may increase psychological pressure and reduce performance. We empirically study the impact of interim rank on performance using data from international diving tournaments. We find that...

A detailed longitudinal dataset is assembled containing annual performance and biographical data for every player over the entire history of professional major league baseball. The data are then aggregated to the team level for the period 1920-2009 in order to test whether teams built on a more...

We investigate the salary returns to the ability to play football with both feet. The majority of footballers are predominantly right footed. Using two data sets, a cross-section of footballers in the five main European leagues and a panel of players in the German Bundesliga, we find robust...

Alex Bryson and colleagues use US baseball data to investigate whether performance suffers if there is too wide a gap between the skills of a team's stars and the rest.

Rapid urbanisation is a major feature of developing countries. Some 2 billion more people are likely to become city residents in the next 30 years, yet urbanisation has received little attention in the modern development economics literature. This paper reviews theoretical and empirical work on...

The size distribution of cities in many countries follows some broadly regular patterns. Any good theory of city size distributions should (i) be able to account for this regularity, but also (ii) rely on a plausible economic mechanism and (iii) be consistent with other fundamental features of...

This paper exploits the division of Germany after the Second World War and the reunification of East and West Germany in 1990 as a natural experiment to provide evidence of the importance of market access for economic development. In line with a standard new economic geography model, we find...

This paper develops a quantitative model of city structure to separate agglomeration forces, dispersion forces and fundamentals as determinants of location choices. The model remains tractable and amenable to empirical analysis because of stochastic shocks to worker productivity, which yield a...

This paper uses micro data from the 1980, 1991 and 2000 population censuses to investigate the role of changes in the industry mix in accounting for the differential trends in the incidence of child work (ages 10-15) across Brazilian states. We find that exogenous compositional changes account...
