Many trade models of monopolistic competition identify cost efficiency as the main determinant of firm performance in export markets. To date, the analysis of demand factors has received much less attention. We propose a new model where consumer preferences are asymmetric across varieties and...

The recent availability of trade data at a firm-product-country level calls for a new generation of models able to exploit the large variability detected across observations. By developing a model of monopolistic competition in which varieties enter preferences non-symmetrically, we show how...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features. Using the concept of Frechet differentiability, we determine a general demand system. The basic tool we use to study the...

We combine spatial and monopolistic competition to study market interactions between downtown retailers and an outlying shopping mall. Consumers shop at either marketplace or at both, and buy each variety in volume. The market solution stems from the interplay between the market expansion...

We propose a general model of monopolistic competition which encompasses existing models while being flexible enough to take into account new demand and competition features. Even though preferences need not be additive and/or homothetic, the market outcome is still driven by the sole variable...

We show that a market involving a handful of large-scale firms and a myriad of small-scale firms may give rise to different types of market structure, ranging from monopoly or oligopoly to monopolistic competition through new types of market structure. In particular, we find conditions under...

We provide a selective survey of what has been accomplished under the heading of monopolistic competition in industrial organization and other economic fields. Among other things, we argue that monopolistic competition is a market structure in its own right, which encompasses a much broader...

We show that a wide class of demand systems for differentiated products, such as those generated by additive preferences, indirectly additive preferences, and Kimball-like homothetic preferences, can be given a multinomial logit foundation provided that the conditional indirect utility is...
