We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

Recent research has shown that the standard labor market matching model fails to match the dynamics of US data. In particular, the model lacks sufficient propagation of shocks. This paper shows that refining the informational structure of the model leads to significant improvements along this...

The validity of family background variables instrumenting education in income regressions has been much criticized. In this paper, we use data of the 2004 German Socio-Economic Panel and Bayesian analysis in order to analyze to what degree violations of the strong validity assumption affect the...

This paper shows that we can normalize job and worker characteristics so that, without frictions,

Most ‘wage curve’ studies treat local labour markets as independent ‘islands’ in the national economy. However, when a local labour market is in close proximity of other labour markets, a local shock that increases unemployment may not lead to lower pay rates if employers fear outward...

In this paper we derive a structural measure for labor market density based on the Ellison and Glasear (1997) "Index for industry concentration". This labor market density measure serves as a proxy for the number of workers that can reach a certain work area within a reasonal amount of traveling...

In this laboratory experiment we study the use of strategic ignorance to delegate real authority within a firm. A worker can gather information on investment projects, while a manager makes the implementation decision. The manager can monitor the worker. This allows her to better exploit the...

Foreign aid’s effectiveness in promoting economic growth remains mired in controversy.We examine the impact of the volatility of aid on economic growth, controlling for the level of aid. A four-year panel analysis is conducted encompassing 155 countries over the period 1966-2001. We find that...

In this paper we employ techniques developed in spatial econometrics to analyse spatial patterns of technology diffusion, to detect clusters and to estimate theoretical models that incorporate space explicitly. These techniques correct for misspecifications resulting from the omission of spatial...

In this note we show that the standard, loglinear growth regression specification is consistent with one and only one model in the class of stochastic Ramsey models. This model is highly restrictive: it requires a Cobb-Douglas technology and a 100% depreciation rate and it implies that risk does...
