In nonlinear pricing environment with correlated types, we characterize optimal selling mechanisms when buyers could form a coalition to coordinate their reports and to arbitrage on the goods. We find that when the types of agents are weakly positively correlated, the optimal weakly...

This paper studies the effects of risk aversion on nonlinear pricing. It first develops a model of risk-averse principal, based on Mussa and Rosen (1978), and finds that the equilibrium allocation increases and approaches the efficient level as the principal's risk aversion increases and tends...

This document (of 279 pages) comprises the proceedings of a roundtable on predatory foreclosure held by the OECD's Competition Committee at the OECD in October 2004. The roundtable addressed various strategies that dominant firms use to eliminate or deter competition, focusing on predatory...

We present a market microstructure model to examine specialist's strategic participation decisions in a security market where there are noise traders, limit order traders, an insider and a specialist. We argue that the specialist's participation rate depends on the depth of the limit book and...

In a market where consumers are not fully informed about the actual production technology or environmental performance of firms that engage in strategic competition, I study the effect of environmental consciousness of consumers on the incentive to invest in cleaner technology. Firms compete in...

I analyze the pricing and investment behavior of a firm that signals the environmental attribute of its production technology through its price to uninformed environmentally conscious consumers. I then analyze the effect of change in environmental regulation on the signaling outcome and the...

Standard policies to correct market power and selection can be misguided when these two forces co-exist. Using a calibrated model of employer-sponsored health insurance, we show that the risk adjustment commonly used by employers to offset adverse selection often reduces the amount of...

In this paper we survey the theoretical and empirical literature on market liquidity. We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how illiquidity...

There is a general presumption that competition is a good thing. In this paper we show that competition in the insurance markets can be bad and that adverse selection is in general worse under competition than under monopoly. The reason is that monopoly can exploit its market power to relax...

The present paper provides a descriptive analysis of the second-degree price discrimination problem on a monopolistic two-sided market. By imposing a simple two-sided framework with two distinct types of agents on one of its market sides, it will be shown that under incomplete information, the...
