This paper develops new estimates of flows into and out of unemployment that allow for unobserved heterogeneity across workers as well as direct effects of unemployment duration on unemployment-exit probabilities. Unlike any previous paper in this literature, we develop a complete dynamic...

This paper explores the role that unobserved heterogeneity within an observed category plays in the dynamics of disaggregate unemployment and in the cross-sectional differences across individuals of the duration of unemployment spells. The distribution of unobserved heterogeneity is...

In this paper I test the capital accumulation conjecture that is used to rationalize return migration decisions in the context of immigrants in Germany and examine how labor market outcomes influence return migration decisions, with particular attention to selection in these outcomes in return...

In this paper, I test the savings accumulation conjecture that is used to rationalize return migration decisions in the context of immigrants in Germany. Using cross-country and time variation in purchasing power parity, I distinguish between the two competing capital accumulation conjectures...

The purpose of the paper is to present a novel approach of a general airport and access mode choice model. Based on data of the German Air Traveller Survey 2003 with a sample size of about 210.000 passengers interviewed at 21 airports a three-stage nested logit model has been estimated in a...

This study tests the hysteresis hypothesis of unemployment in fourteen OECD countries by examining the stationarity of unemployment rates using several panel unit root tests. Empirical results show that the hysteresis hypothesis cannot be rejected for majority of the OECD when the tests are...

The purpose of this paper is to present a new kind of discrete choice model called "Generalized Neural Logit Model" applied exemplarily to the case of airport and access mode choice. This approach employs neural networks to model the utility function of a discrete choice model and correlations...
