We investigate the robustness of the new foreclosure doctrine and its associated welfare implications to the introduction of incomplete information. In particular, we let the upstream firm’s marginal cost be private information, unknown to the downstream firms. The previous literature has...

Extending Milgrom and Roberts (1982) we present an infinite horizon entry model, where the incumbent(s) may use the current price to signal its strength to deter entry. We show that, due to the importance of entrants' types on the post-entry duopoly/oligopoly pro?ts, the incumbent(s) may want to...

Requiring agents with private information to select from a menu of incentive schedules can yield efficiency gains. It will do so if, and only if, agents will receive further private information after selecting the incentive schedule but before taking the action that determines where on the...

A dynamic pricing model is studied where a seller of an asset faces a sequence of potential buyers whose valuation distribution is unknown to the seller. The seller learns more about the distribution in the selling process and becomes less optimistic as the object remains unsold. We characterize...

This paper considers a long-term relationship between a firm and a privately informed trading partner, say a buyer, when both parties bargain over a price in each period and when a toakeover may take place.

We analyse the roles of social network topology and size on the monopoly pricing of network goods in a market, where consumers interact with each other and are characterised by their social relations. The size effect is the well-known network externalities phenomenon, while the topological...

I consider the problem of the design of an optimal self-selection contract scheme for a principal who is buying a good from an agent which has the opportunity of making a cost-reducing unobservable investment prior to the contracting stage. Because of a hold-up problem, the agent will randomizes...

We consider nonlinear pricing policies that are designed by a social welfare maximizer who operates under a non-negative profit requirement. In our two-type economy, we characterize the set of all feasible nonlinear pricing policies and the frontier of the utility possibility set. Our results...

This paper considers a firm whose potential employees have private information on both their productivity and the extent of their fairness concerns. Fairness is modelled as inequity aversion, where fair-minded workers suffer if their colleagues get more income net of production costs. Screening...

In this paper, I consider the problem of designing an optimal screening contract for a principal facing an agent whose type comes as a sequence that unfolds through time. Formally, the agent has a private ex ante type that stands for the expected value of his private ex post type. Under full...
