We formulate a model that explicitly separates two functions in the innovation process: The introduction of new goods and the quality improvement of existing goods. While the latter is performed by the corporate R+D sector, the first is performed by entrepreneurs. We show that in a three sector...

This paper deals with innovative activities of firms, the resulting market success as well as the interdependencies between both. In a first theoretical part, different cases of those interdependencies are investigated by the way of a simple model based on replicator dynamics. It is shown that...

This paper presents a History Friendly Model which addresses the issue of the bifurcation in "technological styles" between US and Britain during the nineteenth century. The model aims at gaining a better understanding of the micro-dynamics that gave rise to different patterns of innovation in...

Industrial clusters develop regionally along the industry's lifecycle and typically exist over many product generations. In order to maintain their innovativeness, they have to develop and adjust along the industry lifecycle. We conduct 142 depth face-to-face interviews in clusters across two...

This paper takes a different perspective toward the escape entry incentive of incumbent firms to innovate. New entrants spawned from incumbents are not necessarily a threat; they can complement incumbents' production by commercializing knowledge incumbents are not willing or able to exploit....

Innovative start-ups are an important driver of economic growth. This article presents empirical evidence on the effects of R&D on new product development, inter-firm alliances and employment growth during the early life course of firms. We use a dataset that contains a sample of new firms that...

Demographic change will be one of the major challenges for economic policy in the developed world in the next decades. In this article, we analyze the relationship between age structure and the number of startups. We argue that an individual's decision to start a business is determined by his or...

The aim of this paper is an investigation on the role of demand in industrial dynamics. Despite the decades-long debate on demand and innovation, theory still lacks a comprehensive analytical formulation. This paper proposes a model where demand is conceived as a peculiar blend of two...

External finance is central for nascent entrepreneurs, people in the process of starting new ventures. We argue that nascent entrepreneurs use patents and prototypes in order to signal their ability to appropriate the returns from their innovation as well as the project's feasibility. Our...

For given product specifications by two competing firms the demand levels are determined by a randomly generated ideal composition of aspects. Firms can vary some or all aspects of these products, based on information about own (and other's) previous demand. Although the product space is much...
