The literature on "Innovation Systems" is divided into several directories. Dif- ferences occur through the definition of the system's borders. This paper intro- duces a methodology how to differentiate between regional and technological effects of cooperative innovation activities and analyzes...

Previous research indicates that risky and uncertain marginal returns from the public good significantly lower contributions. This paper presents experimental results illustrating that the effects of risk and uncertainty depend on the employed parameterization. Speci?cally, if the value of the...

The notion of choice inconsistency is widely spread in the literature on behavioral economics. Several approaches were used to account for the observation that people reverse their choices over time. This paper aims to explain the formation of resolutions regarded as internal self-binding...

A recent literature has pointed at potential negative effects of exchange rate volatility on innovation. In this paper, we propose that there may be a direct effect as well as an indirect effect via export activity. We test these hypotheses for sectoral R&D intensities using OECD panel data for...

This paper analyzes the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. The central hypothesis states that technologies that become...

The measurement of social norms plays a pivotal role in many social sciences. While economists predominantly conduct experiments, sociologists rather employ (factorial) surveys. Both methods, however, suffer from distinct weaknesses. Experiments, on the one hand, often fall short in the...

We investigated the dependence of threat perception and reaction on social distance estimation. Social identity threat was imposed within a 2x2 between subjects design, with N=163 students reading a criticising comment about their ingroup assigned to originate from one of two possible outgroups....

Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new...

We apply a reduced-form vector autoregression model to analyze the growth processes of Italian manufacturing firms, 1989-1997. We focus in particular on lead-lag associations describing the coevolution of employment growth, sales growth, growth of profits and labour productivity growth....

The claim of a positive association between a firm's social assets and its innovative capacity is a widely debated topic in the literature. Although controversial, such an argument has informed recent innovation policy across Germany, increasingly directed to cluster formation. In the light of...
