This paper explores the effects of offshoring, technology and Chinese import competition on labor market polarization in European countries. We find that polarization occurs mostly as a result of polarization within individual industries, while the reallocation of employment away from less...

We consider the efficiency of Cournot and Bertrand equilibria in a duopoly with substitutable goods where firms invest in process R&D. Under Cournot competition firms always invest more in R&D than under Bertrand competition. More importantly, Cournot competition yields lower prices than...

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....

Does competitive pressure foster innovation? In addressing this important question, prior studies ignored a distinction between discrete innovation aiming at entirely new technology and continuous improvement consisting of numerous incremental improvements and modifications made upon the...
