We develop a model to show that cartels that produce goods with lower durability are easier to sustain implicitly. This observation gen- erates the following results: 1) implicit cartels have an incentive to pro- duce goods with an inefficiently low level of durability; 2) a monopoly or explicit...

This paper studies the effectiveness of interim information in reducing inefficiencies in long term relationships. If the interim information is verifiable, it resolves all problems of asymmetric information. Under nonverifiability, the information alleviates the contracting problem only...

Stressing the multi-dimensional character of quality, I propose a new theory of planned obsolescence as an incentive device that benefits consumers. I argue that planned obsolescence increases the frequency of repurchases and, therefore, enables consumers to punish producers faster for a lack of...

The paper studies procurement contracts with pre-project investigations in the presence of adverse selection and moral hazard. To model the procurer's problem, we extend a standard sequential screening model to endogenous information acquisition with moral hazard. The optimal contract displays...

This paper considers the canonical sequential screening model and shows that when the agent has an ex post outside option, the principal does not benefit from eliciting the agent's information sequentially. Unlike in the standard model without ex post outside options, the optimal contract is...

We study ex post information rents in sequential screening models where the agent receives private ex ante and ex post information. The principal has to pay ex post information rents for preventing the agent to coordinate lies about his ex ante and ex post information. When the agent’s ex ante...

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...

Using an agency model, we show how delegation, by generating additional private information, improves dynamic incentives under limited commitment. It circumvents ratchet effects and facilitates the revelation of persistent private information through two effects: a play-hardball effect, which...

We study (energy) markets with dirty incumbents and costly entry by clean producers. For intermediate entry costs, the market outcome exhibits inefficient production and inefficient entry. A policy mix of three popular regulatory instruments—taxation on polluters, feed-in tariffs for clean...

We provide elementary insights into the effectiveness of certification to increase market transparency. In a market with opaque product quality, sellers use certification as a signaling device, while buyers use it as an inspection device. This difference alone implies that seller-certification...
