Innovators who have developed advanced technologies, along with launching new products by themselves, often license these technologies to their rivals. When a firm launches a new product, product positioning is also an important matter. Using a standard linear city model with two firms, we...

This paper investigates an asymmetric duopoly model with a Hotelling line. We find that helping a small (minor) firm can reduce both social and consumer surplus. This makes a sharp contrast to existing works showing that helping minor firms can reduce social surplus but always improves consumer...

We investigate a Cournot model with strategic R&D investments wherein efficient low-cost firms compete against less efficient high-cost firms. We find that an increase in the number of high-cost firms can stimulate R&D by the low-cost firms, while it always reduces R&D by the high-cost firms....

We investigate the incentive and the welfare implications of a merger when heterogeneous oligopolists compete both in process R&D and on the product market. We examine how a merger affects the output, investment, and profits of firms, whether firms have merger incentives, and, if so, whether...

There is substantial empirical evidence that innovation is geographically concentrated. Unlike what is generally assumed, however, it is not clear that localised knowledge spillovers provide a theoretically valid explanation for this. Studying spillovers of cost-reducing technology between...
