The COVID-19 pandemic has affected firms in all economies worldwide. We investigate the impact of the pandemic on firms’ innovation activities. Employing data from a representative sample of German firms, we find consistently with real options theory that negatively affected firms...

This paper examines the link between liquidity constraints and investment behaviour on the one hand, and firm size on the other for a large sample of German firms over the time period 1968-85. The results indicate that smaller firms tend to have investment functions which are more sensitive to...

The purpose of this paper is to link the twin horns of the European economic dilemma - unemployment and a loss in international competitiveness - to a lack of innovative activity. In Germany the Innovationskrise (innovation crisis) combines with the Standortkrise (location crisis) and the...

This is particularly important for countries such as Germany, where subsidized child care is rationed and...

We study spatio-temporal variation of peer effects in rooftop photovoltaics adoption of households. Our investigation employs locational data on potential adopters and a geocoded data set of all grid-connected photovoltaic systems set up in Germany through 2010. The detailed locational data...

This study presents a novel empirical approach to identify financing constraints for innovation based on the idea of an ideal test as suggested by Hall (2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they choose additional innovation...
