I derive and estimate a model for profit maximization of German magazines. Quarterly data on German women's magazines observed between 1998 and 2001 are used in the econometrics. Main empirical results are that magazines with particularly circulation-sensitive advertising prices set cover prices...

This paper presents structural estimates for a bargaining model which nests the right-to-manage, the efficient wage bargaining, the seniority and the standard neo- classical labor demand model as special cases. In contrast to most existing models, our approach accounts for heterogeneous skill...

We estimate the effects of past self-employment experience on subsequent earnings in wage work using the population of Danish citizens between 16 and 65 years of age that we observe between 1980 and 1996. Specifically, we analyze how the effects of previous self-employment experience are...

Cultural and social borders can be stumbling blocks to internationalization (frequent errors, delays). We investigate the persistent roots of liability of foreignness and identify two major factors conceptually: a lack of host country legitimacy (demand side) and a lack of responsiveness on the...

Determining the research and development (R&D) boundaries of the firm as the choice between internal, collaborative and external technology acquisition has since long been a major challenge for firms to secure a continuous stream of innovative products or processes. While research on R&D...

This paper uses data on the population of German magazines for the period 1973 to 2004 to show that, contrary to conventional wisdom, there is little evidence for magazine readers disliking advertising. Many magazines in fact have readers who appreciate advertising. The degree of appreciation...

We measure the quantitative importance of labor mobility as a vehicle for the transmission of knowledge and skills across firms. For this purpose we create a unique data set that matches all applications of Danish firms at the European Patent Office to linked employer-employee register data for...

This paper analyzes the persistence of firms’ exporting behavior in a panel of West German manufacturing firms. Dynamic binary choice models allow us to distinguish between true and spurious state dependence in firm performance. Using random effects models as well as a recent fixed effect...

We analyze the relationship between website visits, magazine demand and the demand for advertising pages using Granger non-causality tests on the basis of an extensive and externally audited quarterly data set for the German magazine market spanning the period I/1998 to II/2004. We use...

Researchers in Germany have nowadays access to confidential micro-data compiled from official statistics in a way that could not have been dreamt of just a few years ago. This article describes the new institutions that grant data access - most importantly the research data centers located...
