Studies of spatial policy interdependence in (local) public policies usually concentrate on the relations between jurisdictions within a single analysed region, and disregard possible extra-regional effects. This paper evaluates the validity of such restriction by studying German local...

The aim of this paper is to take a structured approach at estimating the coefficients of factors explaining movements of the labour share across countries. In particular, we focus on proper dynamic specification and test the validity of the homogeneity assumption of slope coefficients frequently...

This paper presents an application of the Generalised Error Correction Model (GECM) for heterogeneous factor demands based on the quadratic cost function. Using data for 26 West German manufacturing industries over the period 1976-1995, it turns out that less general specifications such as the...

We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

Actors on print media markets face two different (and interrelated) demand curves: the demand for copies and the demand for advertising space. This paper develops a realistic, yet simple, model of print media industries. In contrast to earlier studies, it takes into account that print media...

We study the role of privacy in the market for mobile applications. For such programs used with smartphones and tablet PCs a very important market has emerged. Yet, neither the role of privacy on that market is well understood, nor do we have empirical evidence regarding its role therein. We...
