In this study we derive a structural econometric model of learning by doing with multiproduct competition from a dynamic oligopoly game. We show the importance to account for multiproduction effects through product differentiation when measuring learning by doing. Using quarterly firm-level data...

In this study we specify and estimate a structural model of multiproduct firms for the semiconductor industry. In addition, we explicitly consider dynamics over the product life cycle. We find that these two aspects have important implications and provide evidence that (i) Spillover and...

This paper analyzes the impact of R&D subsidies on incumbent firms to introduce new goods. We are especially interested in investigating various consequences of government subsidies for R&D, provided to firms that o.er products of di.erent qualities. This study examines the incentives of...
