This paper analyses the relationship between past innovation output, competition, and future innovation input in a dynamic econometric setting. We distinguish two dimensions of competition that correspond to the concepts of product substitutability and entry barriers due to fixed costs. Based on...

We examine impacts of different types of environmental innovations on firm profits. Following Porter's (1991) hypothesis that environmental regulation can improve firms' competitiveness we distinguish regulation induced and voluntary environmental innovations. We find that innovations which...

Buyer power is widely considered to decrease innovation incentives of suppliers. However, there is little empirical evidence for this statement. Our paper analyses how buyer power influences innovation incentives of upstream firms while taking into account the type of competition in the...

Skilled labor is a key input to the innovation process. A shortage in supply of skilled labor may hence impede innovation activities, resulting in lower productivity gains. While governments are concerned about these likely negative impacts, there is only limited empirical evidence whether and...

Recent empirical evidence has shown that firm’s innovation behavior exhibits high persistency but not much is known about potential contingencies affecting the degree of persistence. This paper focuses on the role of the local knowledge environment and asks how local knowledge spillovers...
