This paper studies the multi-product firms with two factors of production: unskilled and skilled labor (talent). Creating new products is skill intensive while production is less skill intensive. By introducing these two tasks a firm operates which act as two seemingly sectors, we show here a...

This paper presents theory and evidence from Chinese firm-product data that, given firm productivity, trade liberalization increases product markups. This finding calls for a reconsideration of the well-established imports-as-market-discipline hypothesis. This paper further verifies underlying...

In the literature of psychology and economics it is frequently observed that individuals tend to conform in their behavior to that of similar individuals. A fundamental question is whether the outcome of such conformity can be consistent with self-interest. We propose that this consistency...

Is conformity amongst similar individuals consistent with self-interested behavior? We consider a model of incomplete information in which each player receives a signal, interpreted as an allocation to a role, and can make his action choice conditional on his role. Our main result demonstrates...

Treating games of incomplete information with countable sets of actions and types and finite but large player sets we demonstrate that for every mixed strategy profile there is a pure strategy profile that is 'epsilon-equivalent'. Our framework introduces and exploits a distinction between...
