Excess capacity is viewed as a distinctive feature and an essential inefficiency of monopolistic competition as the large-group case of imperfect competition. Using a simple geometrical approach and studying the demand and cost curves faced by the individual firm, we find that there is little...

Studying intra-industry trade involves theoretical explanations and empirical methods to measure the phenomenon. Indicators have been developed to measure the intensity of intra-industry trade, leading to theoretical models explaining its determinants. It is essential to distinguish between...

To provide a more flexible workhorse model of temporary price reductions or `sales', this paper presents a substantially generalized `clearinghouse' sales framework. Our framework permits multiple dimensions of firm heterogeneity, and views firms as competing directly in utility rather than...

There is widespread evidence that geographical borders reduce trade. This paper presents a theoretical model capable of providing a succinct comparison of three broad forms of trade barriers involving i) trade costs, ii) localized tastes, and iii) information frictions. Despite being...

In recent years, the increasing awarding of patents has captured the attention of scholars operating in different fields. The economic literature has studied the causes of this proliferation; we propose an entry game focusing on one of the consequences, showing how an incumbent may create a...

We investigate the role tacit collusion plays in Asymmetric Price Transmission (APT), the tendency of prices to respond more rapidly to positive than to negative cost shocks. Using a laboratory experiment that isolates the effects of tacit collusion, we observe APT pricing behavior in markets...

The West African Economic and Monetary Union (UEMOA) was established by France to counteract the dominance of Anglophone countries in West Africa, particularly Nigeria and Ghana, over Francophone West Africa. Francophonie in French West Africa is mainly driven by a power elite, the 'Pré...
