When two countries starting from different quality levels (reflecting different conditions on domestic market demands) open to trade, two possible equilibria arise. In the first, the quality leader maintains its position. In the second, leapfrogging occurs. However, the latter is possible only...

The log it model is usually derived from a discrete choice approach with stoc hastic utilities. It is shown here that the logit demand system may also be derived from the maximization of a deterministic, entropy-type utility. The latter may be interpreted as the preference function of a...

The authors introduce commodity taxation into a vertical differentiation model with endogenous product selection. They show that a uniform ad valorem tax lowers both qualities, distorts the allocation of consumers between firms, and lowers the consumer prices of both variants. A small uniform...

We analyze a class of two-stage games where rival firms incur real resource costs in manipulating their marginal costs, so as to influence the outcome of the game they want to play in stage two. Marginal costs may be manipulated by various means, such as redistribution of productive assets,...

In this article, we consider a knowledge accumulation problem within an organization that cannot prevent the worker from quitting and using the knowledge outside the organization. We show that knowledge accumulation is delayed: The fraction of working time allocated to knowledge creation is...
