The role of geographical proximity in fostering connections and knowledge flows between innovative actors ranks among the most controversial themes in the research of innovation systems, regional networks and new economic geography. While there is ample empirical evidence on the constituent...

We study the effects of a German national cluster policy on the structure of collaboration networks. The empirical analysis is based on original data that was collected in fall 2011 and late summer 2013 with cluster actors (firms and public research organizations) who received government...

At least since Schumpeter published his work "The Theory of Economic Development" (1912), a wide body of literature has focused on the evolutionary process behind firm growth and survival. Recently a growing interest is devoted to the variable "location" as a critical factor, shaping firm...

Cluster policies are often intended and designed to promote interaction in R&D among colocated organisations, as local knowledge interactions are perceived to be underdeveloped. In contrast to the popularity of the policy measure little is known about its impact on knowledge networks, because...

The article serves as an introduction to the empirical analysis of innovation or knowledge networks based on patent data with a particular focus on regional networks. I provide a review of the literature of innovation networks and how it connects to systemic approaches within the field of...

A principal-agent multitasking model is used to explore the effects of different tax schemes on innovation in a pure knowledge economy. Corporate taxes and labor income taxes can affect both the firm owner’s and the employee’s incentives to commit to innovative tasks, when the former...

This paper discusses the link between R&D and productivity across the European industrial and service sectors. The empirical analysis is based on both the European sectoral OECD data and on a unique micro longitudinal database consisting of 532 top European R&D investors. The main conclusions...

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...

Ever since its introduction in the 1990s, the systems of innovations (SI) concept has received a great deal of attention from researchers and politicians. The systems of innovation policy (SIP) approach, which is based on the SI concept, is considered an alternative to neoclassical theory. Its...

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...
