This paper models a generalized form of monopolistic competition such that consumers are differentiated horizontally by taste while firms are differentiated vertically by quality location. Consumers have quadratic transportation costs of disutility from consuming a non-ideal brand, and firms are...

The Great Recession, which was preceded by the financial crisis, resulted in higher unemployment and inequality. We propose a simple model where firms producing varieties face labor-market frictions and credit constraints. In the model, tighter credit leads to lower output, lower number of...

We develop a monopolistic-competition model of closed two-sector one-factor economy, where agents are (continuously) heterogeneous in their entrepreneurship abilities and choose between being employees or entrepreneurs. The sufficient conditions in terms of variable elasticity of substitution...

I analyze two opposing effects of firm dynamics on productivity over the business cycle. Consider net exit, on the one hand it reallocates resources to incumbents whose productivity improves through scale economies, on the other hand it reduces the competitive pressure incumbents face which...

Here we reproduce the table of contents and the introductory chapter to our book of related essays published by Edward Elgar. These essays deal with the important implications of allowing for the distribution of goods in characteristic space and of producers in geographic space. Although several...

This paper builds an evolutionary model of an industry where firms produce differentiated products. Firms have different average cost functions and different demand functions. Firms are assumed to be totally irrational in the sense that firms enter the industry regardless of the existence of...

This paper shows that a monopolistically competitive equilibrium can evolve without purposive profit maximization. Specifically, this paper formulates a precise evolutionary dynamic model of an industry where there is continuous entry of firms that randomly select their output levels on entry...

This paper analyzes the behavior of prices and finished-goods inventories in a model of monopolistic competition, where the motivation for holding inventories is the prospect of lost sales. An eventual goal of the present investigation is the development of an empirical framework, based on a...
