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 the problem of an investor that buys an equity stake in an entrepreneurial venture, under the assumption that the former cannot monitor the latter’s operations. The dynamics implied by the optimal incentive scheme is rich and quite different from that induced by other models of...

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...

The benefits of implementing Unemployment Insurance Savings Accounts (UISAs) are studied in the presence of the multiple sources of information frictions often existing in developing countries. A benchmark incomplete markets economy is calibrated to Mexico in the early 2000s. The unconstrained...

In well-functioning democracies, the policymaking process should in principle respond to persistent economic inequality with corrective policies. This process is set in motion through majority demands for redistributive taxation and spending that elected representatives eventually supply through...

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...

I study a multi-sender signaling game between an uninformed decision maker and two senders with common private information and conflicting interests. Senders can misreport information at a cost that is tied to the size of the misrepresentation. The main results concern the amount of information...

This paper analyzes the implications of those types of interventions that affect misreporting costs. I study a model of communication between an uninformed voter and a media outlet that knows the quality of two competing candidates. The alternatives available to the voter are endogenously...

Governments often pursue procyclical fiscal policies, even though they reduce voter welfare. Is this because voters actually prefer procyclical policies? The analysis in this paper exploits the first individual-level evidence from an original survey of 12,000 respondents in 8 countries across...

We use perturbation analysis to study independent private-value all-pay auctions with weakly risk-averse buyers. We show that under weak risk aversion: 1) Buyers with low values bid lower and buyers with high values bid higher than they would bid in the risk neutral case. 2) Buyers with low...
