Immigrants in Germany have poor earnings performance relative to natives. Claiming that human-capital endowments determine earnings potentials rather than actual earnings, a stochastic earnings frontier is estimated and used to seek systematic differences between natives and migrants for GSOEP...

This study uses the concept of shadow prices formeasuring the impacts of climate change. By estimatinga restricted profit function rather than a cost or aproduction function the explanatory power of the modelis increased because of an endogenous outputstructure. Using low aggregated panel data...

Based on an unbalanced panel of all Bavarian cooperative banks for the years of 1989-97 which includes information on 283 mergers, we analyze motives and cost effects of small-scale mergers in German banking. Estimating a frontier cost function with a time-variable stochastic efficiency term we...

Using 1992 data of 1490 banks covering about 40% of German banking, we specify a multi-product translog cost function and follow the “thick frontier”-approach to control for cost inefficiency when evaluating the technology of banking. Scale economies are found to exist up to a size of about...
