Identifying the impact of local firm concentration on individual firm performance is likely to produce a selection bias related to the positive effects of local concentration if agglomeration economies and natural advantages coincide. We overcome this problem by exploiting exogenous variation...

We shed new light on the relative importance that schools’ ability to produce high achievers in math has for economic growth. Drawing on data from the International Mathematical Olympiad (IMO), the world championship in mathematics for high school students, we construct a measure for a...

We provide evidence on the fit of the hybrid New Keynesian Phillips curve for selected Euro zone countries, the US and the UK. Instead of imposing rational expectations and estimating the Phillips curve by the Generalized Method of Moments, we use direct measures of inflation expectations from...

This paper evaluates the performance of simple policy rules in an open economy. By introducing a high degree of exchange rate uncertainty we find that policy rules with an important feedback from movements in the real exchange rate are very robust to uncertainty about the true exchange rate...

We experimentally compare standard two-player trust games to three-player trust games, where two trustors compete for one trustee. We argue that a competitive environment could affect how the trustors’ behaviour is perceived by the trustee. If two trustors compete for the favour of a trustee,...

We test whether new firms locate close to incumbent firms of the same industry. Tendencies to coagglomerate may explain the general wisdom that industry location is highly persistent over time. We perform separate analysis for East and West Germany which enables us to study two integrated areas...

For the open economy, the workhorse model in intermediate textbooksstill is the Mundell-Fleming model, which basically extends theinvestment and savings, liquidity preference and money supply (IS-LM)model to open economy problems. The authors present a simple NewKeynesian model of the open...
