We propose a new approach to measuring the effect of unobservable private information or beliefs on volatility. Using high-frequency intraday data, we estimate the volatility effect of a well identified shock on the volatility of the stock returns of large European banks as a function of the...

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

This paper examines the role of venture capital on a firm's innovation activities by using a data set of German technology-based firms founded between 1996 and 2005. Innovation is proxied by patent counts and an index of innovativeness which reflects the degree to which a young firm has...

This article analyzes how the perceived effectiveness of intellectual property protection and competitive pressure affect firms' innovation strategy choices, concretely, whether to abstain from innovation, to introduce products that are known in the market but new to the firm (imitation) or to...

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...

This paper explores the role of R&D worker mobility on innovation performance. As one main novelty, we employ churning as a measure for worker mobility. Churning depicts the number of workers which are replaced by new ones. It is a very informative indicator since a firm may be exposed to...

Do financial market analysts use structural economic models when forecasting exchange rates? This is the leading question analysed in this paper. In contrast to other studies we use expectations data instead of observable variables. Therefore we analyse the implicit structural models forecasters...

This paper analyzes the medium-term growth performance of firms that exclusively received start-up assistance from programs administered by the Deutsche Ausgleichsbank (DtA), a state owned bank, within two years after startup. I apply a parametric selection approach that controls for two...

This study applies a full information maximum likelihood (FIML) estimator of the sample selection model with bivariate selection rule for the investigation of the impact of subsidised firm foundation from unemployment on employment growth of the firm. The empirical analysis is based on the ZEW...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a firm can costlessly receive external knowlegde best. Since knowledge spillovers are unmeasurable, a 'goodness of fit'...
