We study the exclusionary properties of nonlinear pricing by dominant firms in a static environment. Optimal price schedules are nonlinear when the rivals’ sensitivity to competitive pressure varies with the “contestable share” of the market. When buyers can dispose of unconsumed units at...

We examine optimal selling mechanisms with ex-ante commitment for a nondurable good when the seller does not observe the times at which strategic consumers arrive on the market and how much they are willing to pay for the good. Assuming consumer risk neutrality, we demonstrate in this...

We adapt the exclusion model of Choné and Linnemer (2014) to reflect the notion that dominant firms are unavoidable trading partners. In particular, we introduce the share of the buyer’s demand that can be addressed by the rival as a new dimension of uncertainty. Nonlinear price-quantity...

We study the exclusionary properties of nonlinear price-quantity schedules in an Aghion-Bolton style model with elastic demand and product differentiation. We distinguish three regimes depending on whether and how the price of the incumbent good is linked to the quantity purchased from the rival...

This article aims at understanding the interplay between pension schemes and tax instruments. The model features extensive labor supply in a stationary environment with overlapping generations and perfect financial markets. Compared with the reference case of a pure taxation economy, we find...

A number of countries have recently implemented variants of a negative incometax, to push the less skilled members of the economy into work, or to make workpay in comparison with welfare benefits. In most cases, these measures haveresulted for the concerned groups in a decrease of the tax rates,...

The analysis of horizontal mergers hinges on a tradeoff between unilateral effectsand efficiency gains. The article examines the role of uncertainty (on theefficiency gains) in this tradeoff. Common wisdom is that the antitrust authoritiesshould be very cautious about random gains. Our results...
