"We discuss the determinants of a successful implementation of an employee suggestion scheme and other measures to stimulate innovation success. Subsequently the effects of the employee suggestion schemes are investigated empirically. We analyse the realisation of cost reductions and...

We estimate the effect of R&D spillovers on sales realized by products new to the firm (imitation) and new to the market (innovation). It turns out that spillovers from rivals lead to more imitation, while inputs from customers and research institutions enhance original innovation.

We estimate the effects of R&D on firms' credit ratings and on financial distress. The main purpose is the comparison of firms in Western Germany and Eastern Germany as a transitional economy. Innovative activity has a positive impact on firm value proxied by ratings in Western Germany, but a...

Knowledge spillovers to competitors are regarded as an important aspect of the innovation process. While a company possibly benefits from incoming information on successful R&D conducted by other companies, a generally high probability of leakage of knowledge in an industry will negatively...

his paper discusses the incentives for innovation when liability is limited or not. Clearly innovative activity involves risk. On the one hand, the risk of firm owners is limited if their liability is limited. On the other hand, credits will be more difficult to receive if liability is limited....

We develop a simple model of competition for the market that shows that, contrary to the Arrow view, endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more than the average firm. We test these predictions with a Tobit model...

Successful innovative activity is a major contribution to the intangible capital of firms. Although its importance is generally acknowledged, the contribution to companies' profits is a priori unclear. We present the results of an empirical study on the effects of the patent stock on...
