A nested model is presented which has both the sequential and multinomial logit model as special cases. This model provides a simple test to investigate the validity of these specifications. Some theoretical properties of the model are discussed. During the analysis a distribution function is...

We study fairness and reciprocity in a Hawk-Dove Game. A variety of recent models gives the same predictions for this game. This allows us to provide a general classification of individuals' types. Contrary to a large number of studies of different games over the last decade, we observe a large...

We study fairness and reciprocity in a Hawk-Dove game. This alllows us to testvarious models in one framework. We observe a large extent of selfish and rationalbehavior. Our results are inconsistent with leading models in this field.

We apply a recently proposed method to disentangle unobserved heterogeneity from risk in returns to education. We replicate the original study on US men and extend to US women, UK men and German men. Most original results are not robust. A college education cannot universally be considered an...

We apply a recently proposed method to disentangle unobserved heterogeneity from risk in returns to education to data for the USA, the UK and Germany. We find that in residual wage variation, uncertainty by far dominates unobserved heterogeneity. The relation between uncertainty and level of...
