The Porter Hypothesis postulates that the costs of compliance with environmental standards may be partially or even fully offset by adoption of innovations they trigger. The timing of the adoption aspect of the Porter Hypothesis has not been captured in formal theory so far. We show in this...

We integrate two workhorse models in economics: The monopolistic competition model of Dixit and Stiglitz and the search unemployment model of Pissarides. Many results of the original models survive. New results concerning the effects of changes in labour (goods) market parameters on goods...

In this paper we integrate two workhorse models in economics: The monopolistic competition model of Dixit and Stiglitz and the search unemployment model of Pissarides. Information and communication technology (ICT) is interpreted as i) technical progress in the matching function of the...

We consider the problem between an employer and a research employee who has not finished a research project in time because of a lack of an innovative idea. The research project yields money in case of finishing it. The decision to be made is whether or not the researcher gets a contract...

The Porter Hypothesis postulates that the costs of compliance with environmental standards may be offset by adoption of innovations they trigger. We model this hypothesis using a game of timing of technology adoption. We show that times of adoption are earlier the higher the non-adoption tax....

The arena of mobile telecommunication in Europe has undergone a technological transition from analogue (first generation) to digital (second generation) technologies. While this transition is immediately attributable to shifts in demand and supply patterns, closer examination reveals that there...

Over the last decade or so, multinational enterprises (MNEs) have shifted from centralised hub structures to multi-hub structures. While these new structures provide greater potential for cross-fertilization of technologies and access to locationspecific competences, promoting effective...

The purpose of this study is to explore the factors that allow firms to benefit from knowledge developed inuniversities and government labs or that drive them to collaborate with these institutions. A number ofstudies have examined this question from various perspectives: the characteristics of...

A model is introduced to analyze the effect of network effects and transactions patterns on the decision by banks (not) to standardize payment systems both domestically and across borders. If only a small share of all transactions is cross-border, banks have strong incentives to maintain...
