A large body of evidence suggests that poor countries tend to invest less (have lower PPP adjusted investment rates) and to face higher relative prices of investment goods. It has been suggested that this happens either because these countries have lower TFP in the investment good producing...

A large body of evidence suggests that poor countries tend to invest less (have lower PPP - adjusted investment rates) and to face higher relative prices of investment goods. It has been suggested that this happens either because these countries have lower TFP in the investment - good producing...

Evolution of technology causes human capital to become obsolete. We study this phenomenon in an overlapping generations setting, assuming it is hard to predict how technology will evolve, and that older workers find updating uneconomic. Among our results is the proposition that (under certain...

Firm numbers first rise, and then fall as the typical industry evolves. This nonmonotonicity in the number of producers is explained in this paper using a competitive model in which innovation opportunities induce firms to enter, but in which a firm's failure to implement new technology causes...

The usual explanation for why the producers of a given product use different technologies involves "vintage-capital": A firm understands the frontier technology, but can still prefer an older, less efficient technology in which it has made specific physical and human capital investments. This...

Brandenburger and Stuart (1996) identified coalitional games as a means of providing precise notions of value to evaluate strategic opportunities. In this paper, we show how coalitional game theory can be utilized to operationalize these approaches. In particular, we demonstrate the importance...

We study a competitive model in which firm managers differ in terms of ability, and the managers' actions are private information. Each firm chooses how able a manager to hire, and optimizes the manager's incentive pay as well as the level of cooperating resources available to the manager. Thus,...
