The relationship between the size of a market and the competitiveness of the market has been of long-standing interest to IO economists. Empirical studies have used the relationship between the size of the geographic market and both the number of firms in the market and the average sales of the...

Do larger markets offer better products? The question has implications both for theories of cities and for theories of market organization. We document that in the restaurant industry, where quality is produced largely with variable costs, the range of qualities on offer increases in market...

We provide a theoretical framework to discuss the relation between market size and vertical structure in the railway industry. The framework is based on a simple downstream monopoly model with two input suppliers, labor forces and the rail infrastructure firm. The operation of the downstream...

Free-entry Cournot equilibria in pure strategies often fail to exist even within a framework of linear demand and constant marginal costs, if firms can choose from a discrete set of technologies. I show that the non-existence problem vanishes if vertical market size is large. An example...

This paper develops a model of international trade where firms are heterogeneous across capacity and productivity. A binding capacity constraint induces firms to raise prices in order to take advantage of access to new markets. This generates markets with a flexible competitive structure giving...
