This paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving innovation that incorporates industries with heterogeneous innovation sizes. Government demand in high-tech industries...

This paper analyzes whether firms conducting internal R&D and acquiring external high-tech equipment experience a complementarity effect. For German CIS data we conduct a complete set of indirect and direct complementarity tests refining the analysis by looking at various types of innovations...

This paper analyses the effects of innovation networks on product and pro-cess innovation and sales growth of high technology SMEs. Innovation net-works are positively related to both product and process innovation, i.e. know-ledge creation. One exception is the negative effect of innovation...

In this paper we investigate factors that influence a firm's decision to implement knowledge management practices. Our focus is on knowledge management practices implemented to increase collaboration between actors within a firm on innovation activities. Using information on over 1,500...

In this paper, we analyze the problem of congestion and quality loss of data transmission through the Internet from an economic perspective. We show that due to the congestion problem, quality sensitive services are likely to be crowded out by high volume but less quality sensitive applications...

This study is about structural change in the energy system. In a first step an econometric model is presented and in a second step diffusion of GTs is embedded theoretically. By focusing on different green technology industries (GT sector) in Germany, we analyze how policy induced demand...

This paper investigates the relevance of government purchasing behavior for innovation-based economic growth. We construct a parsimonious Schumpeterian growth model in which demand from the public sphere can effectively alter the economy's rate of technological change. We incorporate results of...

This paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving in-novation that incorporates industries with heterogeneous innovation sizes. Government de-mand in high-tech industries...

The emergence and evolution of a technology is intimately related to it's knowledge base. A knowledge base shows certain dynamics and evolves over time. Knowledge accumulation, especially the in-flow of knowledge from sources external to an industry, is crucial for the technology's knowledge...

Over the past decades, entrepreneurial activity has started to be considered a third mission of higher education institutions. Our study examines the extent to which entrepreneurship at universities is driven by spatial proximity between university faculties. To this end, we use a new dataset...
