Abstract:: What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discriminating patents by technology field, it is demonstrated that patents that receive citations across technology fields survive longer than other patents. Patents that receive citations within the same technology field lapse earlier.

Abstract:: In this paper, we analyse how R investment decisions are affected by R spillovers between firms, taking into consideration that more R investment improves the ability to learn from competing firms - the so-called absorptive capacity effect of R The model in this paper is an extension of d'Aspremont and Jacquemin (1988), where they show that exogenous R spillovers reduce the incentive to invest in R when firms compete in a Cournot duopoly. Our model treats R spillovers as endogenous, being a function of absorptive capacity effects. Contrary to earlier studies, we show that absorptive capacity effects do not necessarily drive up the incentive to invest in R This only happens when the market size is small or the absorptive capacity effect is weak. Otherwise firms will actually chose to cut down on R Furthermore, absorptive capacity effects also increase the critical rate of spillovers that determines whether participating in research joint ventures leads to lower or higher R investment. Finally, we show that strong learning effects of own R are not necessarily goodfor welfare. Moreover, if the market size is large, welfare will be at its highest when the learning effect is small.

Abstract:: This article presents two models of international trade under monopolistic competition. In increasing returns sectors firms face fixed, in addition to variable, trade costs, therefore both exporters and non-exporters may coexist. While nonexporters benefit from access to large domestic markets, exporters benefit from access to large foreign markets. Consequently, a small country has a higher share of exporting firms than a large one. In contrast to standard models, increasing returns sectors turn out more open in small countries than in large ones, and small countries may be net exporters of such commodities, despite the disadvantage of a smaller home market.

Abstract:: International negotiations on trade (e.g. GATT and TRIPS) have typically been of the package-form, and different issues have therefore been linked to each other. Trade issues have not been linked to e.g. environmental agreements in negotiations, however. This paper studies the outcome of linked bargaining, where two issues are simultaneously negotiated over by two countries. We notice that there always exist gains from linkages in bargaining, and that such linking will always occur in equilibrium if there is a pre-stage where the countries are bargaining over the agenda. The outcome under linked bargaining is compared with the outcome under separate negotiations, and the circumstances where a country will gain or lose from linking are characterized. The results help us to understand different countries' preferences for linkages in bargaining.

Abstract:: Research on economic growth has experienced remarkable progress the last decade. The neoclassical perspective has benefited from development of new mathematical methods and new approaches to market structure, economics of scale and spillover effects. At the same time evolutionary theories on economic development have appeared, partly competing but also complementary to neoclassical theorising. In this paper, the development of the two perspectives on economic growth is reviewed and they are compared with each other. Despite evident differences there seems to be convergence between the two traditions. The two perspectives therefore do not belong to different paradigms in the Kuhnian sense and they can hardly be categorised as two isolated research programmes in the sense of Imre Lakatos. Evolutionary and neoclassical growth economics draw inspiration from similar sources, they are overlapping and to some extent complementary. The two traditions also interact with each other.
