Multivariate Tobit models are estimated using German cross?sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT?components. If two ICT?components are complements, they are correlated (provided that agents act rationally)....

In the 1990s, patenting schemes changed in many respects: upcoming new technologies accelerated the shift from price competition towards competition based on technical inventions, a worldwide surge in patenting took place, and the ?patent thicket? arose as a consequence of strategic patenting....

Public procurement has been at the centre of recent discussions on innovation policy on both European and national levels (e.g., Aho-Report, Barcelona Strategy). It has a large potential to stimulate innovation since it accounts for 16% of combined EU-15 GDP. We embed public procurement for...

We consider an extension of conventional univariate Kaplan-Meier type estimators for the hazard rate and the survivor function to multivariate censored data with a censored random regressor. It is an Akritas (1994) type estimator which adapts the nonparametric conditional hazard rate estimator...

Recent studies have documented extensive heterogeneity in firm performance within countries, and innovation has been found as an important determinant. This paper addresses the issue of innovation firm performance across countries. A growing number of national firm level studies on the...

This paper derives a three stage Cournot?oligopoly game for product innovation, expenditure on introducing the product and competition on the product market. Product innovation is assumed to increase consumer utility but is effective only if the innovating firm invests in marketing, so that...

Reducing institutional rigidities in product and labour markets is key to lowering unemployment. The impact of such labour and product market reforms, however, depends crucially on the country-specific regulatory framework. In this paper, we estimate the country-specific impact of changes in six...

Isolated effects of labor and product market institutions as well as the interaction between both aforementioned categories on unemployment have been extensively discussed in the empirical literature. However, interaction effects between individual labor market institutions have been widely...

This paper estimates the impact of training incidence and duration on employment transitions accounting for the endogeneity of program participation and duration. We specify a very flexible bivariate random effects probit model for employment and training participation and we use Bayesian Markov...

I derive and estimate a model for cover price setting in print media markets where actors are faced by two interrelated demand curves: the demand for the print medium and the demand for advertising space. Publicly available data on German women?s magazines observed between 1998 and 2001 are used...
