In 2002 the leading European football clubs reacted to the increasing player salaries by signing a voluntary agreement to limit player salaries to 70% of revenues. We analyse under which conditions a voluntary salary cap agreement is self-enforcing. Based on a simple model of a league with two...

Torgler and Schmidt (2007) have recently found a positive impact of pay on player performance in German soccer, measured by the number of goals and assists scored within a season. This note shows that their result is spurious as both a player's wage and goal/assist scoring are driven by...

We explore two unexpected changes in flight regulations to identify the causal effect of aircraft noise on health. Detailed yearly noise metrics are linked with panel data on health outcomes using exact address information. Controlling for individual and spatial heterogeneity, we find that...

We analyze the adjustment of housing prices after an exogenous shock. Using continuous records of the housing market around a major European airport (ZRH, Switzerland) and an unexpected change in flight regulations induced by the neighboring country Germany, we find that apartment rents take...

In October 2003, a new flight regime was introduced at Zurich airport that significantly changed the levels of noise pollution in surrounding communities. We investigate the impact of the new flight policy on apartment prices using a hedonic price model and a non-linear difference-in-differences...
