We show how size-contingent laws can be used to identify the equilibrium and welfare effects of labor regulation. Our framework incorporates such regulations into the Lucas (1978) model and applies this to France where many labor laws start to bind on firms with exactly 50 or more employees....

In some markets vertically integrated firms sell directly to final customers but also to independent downstream firms with whom they then compete on the downstream market. It is often argued that resellers intensify competition and benefit consumers, in particular when wholesale prices are...

When today’s actions can affect tomorrow's value of an asset and when the principal does not have access to hard information, either about productive activity or monitoring activity, two incentive problems must be simultaneously solved: first, the ‘ex-ante’ moral hazard problem of inducing...

When penalties for first-time offenders are restricted, it is typically optimal for the lawmaker to overdeter repeat offenders. First-time offenders are then deterred not only by the (restricted) fine for a first offense, but also by the prospect of a large fine for a subsequent offense. Now...

Patents are a useful but imperfect reward for innovation. In sectors like pharmaceuticals, where monopoly distortions seem particularly severe, there is growing international political pressure to identify alternatives to patents that could lower prices. Innovation prizes and other non-patent...

Strategic delegation to an independent regulator with a pure consumer standard improves dynamic regulation by mitigating ratchet effects associated with short term contracting. A pure consumer standard alleviates the regulator's myopic temptation to raise output after learning the firm is...

The increased availability of process measures implies that quality of care is in some areas de facto verifiable. Optimal price-setting for verifiable quality is well-described in the incentive-design literature. We seek to narrow the large gap between actual price-setting behaviour in...

The paper studies the impact of government budget constraint in a pure adverse selection problem of monopoly regulation. The government maximizes total surplus but incurs some cost of public funds à la Laffont and Tirole (1993). An alternative to regulation is proposed in which firms are free...

We present a model of optimal contracting between a purchaser (a principal) and a provider (an agent). We assume that: a) providers differ in efficiency and there are two types of provider; b) efficiency is private information (adverse selection); c) providers are partially altruistic or...

This Paper analyses the impact of asymmetric information within countries on the pattern of international trade. We append to the standard 2×2 Heckscher-Ohlin model of a small economy a continuum of sectors producing intermediate non-tradable goods. Those goods are produced by monopolies having...
