Under certain conditions the optimal insurance policy will offer full coverage above a deductible, as Arrow and others have shown long time ago. Interestingly, the same design of insurance policies applies in case of a single loss and ex-ante moral hazard. However, many insurance policies...

Drawing broadly on the literature on the political economy of the financial crisis, the paper looks at deregulation as a market driven process that culminated in a collective action failure. In the run up to the 2008 Financial Crisis strong competition and moral hazard went hand in hand and that...

The paper argues that financial deregulation incentivized financial firms to take excessive risks and over-expand because it turned social insurance against systemic risk into a common pool (or open) resource. The increased size and complexity of deregulated financial markets in turn raised the...

The probability of income loss depends on talent and effort. Effort has positive externalities and therefore individuals are proportion to their perceived diligence. The social norm requires more effort from individuals perceived as more talented, but talent is private information and...

In this paper, I explore how optimal aggregate dynamics can be shaped by the presence of moral hazard in unemployment insurance. I also analyze the optimal provision of unemployment insurance and the implications for the amount of cross-sectional heterogeneity. The economy that I consider embeds...

This paper aims to characterise a dynamic, incentive-compatible contract for the provision of health services, allowing for both moral hazard and adverse selection. Patients' severity changes over time following a stochastic process and is private information of the provider. We characterise the...

We study internal incentives, transparency and firm performance in multidivisional organizations. Two independent divisions of the same firm design internal incentives, and decide whether to publicly disclose their performances. In each division a risk-neutral principal deals with a risk-averse...

Consider a large market with asymmetric information, in which sellers choose whether to cooperate or deviate and cheat their buyers, and buyers decide whether to re-purchase from different sellers. We model active trade relationships as links in a buyer-seller network and suggest a framework for...

We present a model in which the media provide voters with information that is tainted by their own preferences, and derive an equilibrium in which media endorsements influence voting behavior. Competition for media endorsement causes political parties to adopt more centrist policies, which...

The paper addresses the mechanism design problem of eliciting truthful information from a committee of informed experts who collude in their information disclosure strategies. It is shown that under fairly general conditions full information disclosure is possible if and only if the induced...
