This paper analyzes whether firms conducting internal R&D and acquiring external high-tech equipment experience a complementarity effect. For German CIS data we conduct a complete set of indirect and direct complementarity tests refining the analysis by looking at various types of innovations...

We analyze the effect of new business formation on the productivity of incumbent manufacturing establishments. We obtain robust empirical evidence of productivity improvements that are due to the emergence of new businesses in the same industry, that is, on the output market. This effect is...

This paper reports results of a 100-round Yes-No game experiment conducted under the random matching protocol. In contrast to ultimatum bargaining, the responder in the Yes-No game decides whether to accept without knowing the proposer's offer. Although both games have the same solution outcome...

We run a market experiment where firms can choose not only their price but also whether to present comparable offers. They are faced with artificial demand from consumers who make mistakes when assessing the net value of products on the market. If some offers are comparable however, some...

This paper studies the effect of social comparison on risk taking behavior. We assume that decision makers evaluate consequences of their choices not only as variations with respect to their economic status but also as variations with respect to the status of their peers. We test experimentally...

In this paper, we analyse the implications of labour market integration in a two-region model with local human capital externalities and congestion eects. We show that integration can be a double-edged sword. Integration and the ensuing agglomeration of skilled labour can reduce 'real' income in...

This paper aims at linking cross border mobility of students and graduates with the financing of higher education. Against the background of institutional features and empirical evidence of the European Union and Northern America, a theoretical framework is developed. This allows analyzing the...

The linear-quadratic (LQ) optimization is a close to standard technique in the optimal control framework. LQ is very well researched and there are many extensions for more sophisticated scenarios like nonlinear models. Usually, the quadratic objective function is taken as a prerequisite for...

The 40 years of socialist regime in East Germany were characterized by a massive anti-entrepreneurship policy. We investigate the reemergence of entrepreneurship in East Germany during its transformation to a market economy following the collapse of the East German state in 1989. It took about...
