This paper investigates empirically firm investment behavior in research and development (R&D). Firms make investments in R&D in order to produce innovations. These innovations in turn improve the firm's future productivity level, pro tability and incentives to invest in R&D. Using German...

Recent years have shown a surge of firms globalising their innovation activities in order to gain from international knowledge. This paper evaluates this strategy by investigating whether firms with international R&D are more innovative than firms doing R&D only in their home country. One main...

The importance of units with pervasive impacts on a large number of other units in a network has become increasingly recognized in the literature. In this paper we propose a new method to detect such influential or dominant units by basing our analysis on unit-specific residual error variances...

In this paper we focus on estimating the degree of cross-sectional dependence in the error terms of a classical panel data regression model. For this purpose we propose an estimator of the exponent of cross-sectional dependence denoted by α; which is based on the number of non-zero pair-wise...

The tensions between books and book markets as expressions of culture and books as products in profit-making businesses are analysed and insights from the theory of industrial organisation are given. Governments intervene in the market for books through laws concerning prices of books, grants...

This paper introduces a novel approach for dealing with the "curse of dimensionality" in the case of large linear dynamic systems. Restrictions on the coefficients of an unrestricted VAR are proposed that are binding only in a limit as the number of endogenous variables tends to infinity. It is...
