This paper investigates the impact of implicit institutions on the decision to become an entrepreneur. Implicit institutions are here defined as mindsets that have developed as the result of norms and traditions and we expect they will have an influence on risk attitudes and opportunity...

Empirical research has shown tremendous productivity differences, even within narrowly defined industries. A great host of studies is explainsing this productivity disparity by factors such as idiosyncratic technology shocks, input price differences, management skills, or international trade....

The literature on Innovation Systems is divided into several directories. Dif- ferences occur through the definition of the system's borders. This paper intro- duces a methodology how to differentiate between regional and technological effects of cooperative innovation activities and analyzes...

This study is about structural change in the energy system. In a first step an econometric model is presented and in a second step diffusion of GTs is embedded theoretically. By focusing on different green technology industries (GT sector) in Germany, we analyze how policy induced demand...
