Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of "cannibalizing" sales of existing varieties. While more productive firms always have a higher market share, there is no...

There is only a few literature on age specific occupational segregation. In this descriptive paper, I focus on job opportunities for newly hired older male and female workers. It is an enriched replication study of Hutchens (ILRR,1988), who showed that firms employ older workers, but hire them...

In this study, we propose our hypothesis that the distinguishable principal-agent relationships of German banks are significantly influencing the risk-taking attitudes of bank managers. Particularly, we intend to substantiate the theory that banks owned by dispersed shareholders or federal state...

Export is dominated by enterprises that trade more than one good with customers in more than one destination country. Germany, one of the leading actors on the world market for goods, is a case in point. Theoretical models of multiple-product, multipledestination exporters that can guide...

In Germany, for the reporting year 2009 transaction-level data on exports and imports of goods have been aggregated at the level of the exporting or importing firm for the first time. In these data the number of goods exported and imported and the number of countries exported to and imported...

This paper contributes to the literature by providing the first evidence on the link between innovation activities (measured by the share of engineers and scientists in the workforce) and exports of German business services firms based on a large representative longitudinal sample of...

This paper presents the first empirical test with German firm level data of a hypothesis derived by Bustos (AER 2011) in a model that explains the decision of heterogeneous firms to export and to engage in R&D. Using a non-parametric test for first order stochastic dominance it is shown that, in...
