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...

A representation for I(2) processes is derived which allows for trend-stationary components and restricts the deterministic part of the process to be at most linear. A two-step statistical analysis of the model is derived. The joint test of I(1) and I(2) cointegrating ranks is shown to be...

This paper analyzes the structure and constancy of a model of export pricing. The empirical model allows for long-run relations between nonstationary variables and feedback from the foreign trade sector to domestic variables and the exchange rate. A conditional VAR model is derived from the...

This paper develops a procedure for testing hypotheses on the full set of cointegration parameters of the I(2) model. It applies this procedure to the analysis of small-country import price determination, extending the standard empirical framework to allow for variables integrated of order two....

We investigate the effect of mobility of highly skilled workers in Denmark on the total patenting activity of the firms involved for the population of R&D active Danish firms observed between 1999 and 2004. Our study documents how workers joining increase firms patenting activity. The effect is...

Scientific knowledge is an important ingredient in the innovation process. Drawing on the knowledge-based view of the firm and the literature on the relationship between science and technology, this paper scrutinizes the importance of university scientists' mobility for firms' innovative...

This article analyzes trade policy dynamics when there are sunk costs of entry and demand uncertainty. A natural generalization of the classic export tax prescription for a domestic industry facing downward-sloping foreign demand is defined and implemented as a dynamic competitive equilibrium...

The authors analyzed the relationship of visits to a magazine's online companion website and total circulation, subscription, and kiosk sales using bivariate vector autoregressions estimated on 67 German magazines that were observed monthly in the period May 1998 to November 2009. Their...

We study the mapping between labor mobility and industrial innovative activity for the population of R&D active Danish firms observed between 1999 and 2004. Our study documents a positive relationship between the number of workers who join a firm and the firm's innovative activity. This...
