Competition forces firms to find new ways to advance in the market and be innovative in order to differentiate themselves from rivals. Design activities may be one of several key factors contributing to new product development. The success story of Apple's iPod has shown that the right design...

The European Commission has recently stepped up its promotion of the "Integrated Product Policy". The objective of the IPP is to support the realisation of environmental product innovations and thus to achieve a broad reduction of all environmental impacts throughout a product's life cycle....

The aim of the Integrated Product Policy (IPP) is to promote product-related eco-innovations. These, in turn, depend on both support for the development of environmentally-friendly products and stimulation of demand for such products. However, it is companies that play the crucial role in the...

Recent years have shown a surge of firms globalising their innovation activities in order to gain from international knowledge. This paper evaluates this strategy by investigating whether firms with international R&D are more innovative than firms doing R&D only in their home country. One main...

This study examines whether staged project management is beneficial or harmful for making product innovations. Using a unique firm survey for Japan, we find that firms that employed staged project management had a higher likelihood of introducing new products to the market. Additional...

The paper aims at testing Florida's concept of the Creative Class using panel data for 323 West German regions for the time period 1975-2004. Applying a dynamic system approach based on GMM, we find that the local concentration of the Creative Class has predictive power for the economic...

Policy makers are increasingly concerned about the combination of market power and massive data collection in digital markets. This concern is fueled by the theoretical prediction that more market power causes firms to collect ever more data from their users. We investigate the relationship...

Do contributions to online content platforms induce a feedback loop of ever more user-generated content or will they discourage future contributions? To assess this, we use a randomized field experiment which added content to some pages in Wikipedia while leaving similar pages unchanged. We find...

I quantify spillovers of attention in a network of content pages, which is challenging, because such networks form endogenously. I exploit exogenous variation in the article network of German Wikipedia to circumvent this problem. Wikipedia prominently advertises one featured article on its main...

Are there positive or negative externalities in knowledge production? We analyze whether current contributions to knowledge production increase or decrease the future growth of knowledge. To assess this, we use a randomized field experiment that added content to some pages in Wikipedia while...
