We propose a simple theory of predatory pricing, based on scale economies and sequential buyers (or markets). The entrant (or prey) needs to reach a critical scale to be successful. The incumbent (or predator) is ready to make losses on earlier buyers so as to deprive the prey of the scale it...

In an intertemporal setting in which individual uncertainty is resolved over time, advance-purchase discounts can serve to price discriminate between consumers with different expected valuations for the same product. Consumers with a high expected valuation purchase the product before learning...

The goal of this paper is to examine the role of multiproduct firms in the market provision of product diversity. The analysis is conducted within the spatial model of nonlocalized competition proposed by Chen and Riordan (2006). It turns out that the effect of multiproduct firms on product...

This paper considers a housing insurance market in which buildings have different damage probabilities. Insurers use imperfect tests to find out about buildings’ damage types. The insurance market is a natural monopoly. If more than one insurer is active, high risk house owners continue to...

This Paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in efficiency, and gives vendors lucrative ex...

We analyse the welfare consequences of an increase in the commissions charged by intermediaries in auction markets. We argue that while commissions are similar to taxes imposed on buyers and sellers the question of incidence deserves a new treatment in auction markets. We show that an increase...

We challenge the view that the presence of powerful buyers stifles suppliers' incentives to innovate. Following Katz (1987), we model buyer power as buyers' ability to substitute away from a given supplier and isolate several effects that support the opposite view, namely that the presence of...

Digital goods are bit strings, sequences of 0s and 1s, that have economic value. They are distinguished from other goods by five characteristics: digital goods are non-rival, infinitely expansible, discrete, aspatial, and recombinant. The New Economy is one where the economics of digital goods...

Fundamental information resembles in many respects a durable good. Hence, the effects of its incorporation into stock prices depend on who is the agent controlling its flow. Similarly to a durable goods monopolist, a monopolistic analyst selling information intertemporally competes against...
