This paper analyzes the incentive effects of pollution taxes versus pollution permits for a budget oriented Government. Pollution permits are analyzed as durable goods, and a pollution tax is seen as an equivalent to leasing pollution permits. First, a general model is developed and then four...

We use the negotiations for large-scale open-access agreements between German research institutions and leading academic publishers to study how changes in the attractiveness of various journals affect the publication behavior of researchers in economics and adjacent fields. First, as German...

This paper analyses the extent of inter-format retail competition between supermarkets, discounters and drugstores in Germany, using data from the German market for diapers. We estimate a random coefficient logit model at the individual household level. Based on consumer substitution patterns,...
