Malpractice in food production entails unacceptable procedures and undesirable product qualities and other negative material outcomes. Despite their physical implications, behavioural sources of risk have become known as moral hazards. The probability of malpractice increases with attached...

We study the problem of provision and cost-sharing of a public good in large economies where exclusion, complete or partial, is possible. We search for incentive-constrained efficient allocation rules that display fairness properties. Population monotonicity says that an increase in population...

We prove by construction that ex post incentive compatible mechanisms exist in a private goods setting with multi-dimensional signals and interdependent values. The mechanism shares features with the generalized Vickrey auction of one-dimensional signal models. The construction implies that for...

We study how excessive debt-GDP ratios affect political sustainability of prudent fiscal policy in country members of a monetary union. We develop a model with free choice of distinct rent-seeking groups to cooperate (or not) in providing public goods, in seeking rents, and in austere debt...

Buyers requiring large parcels of land for development purposes engage several owners in a bilateral trade seeking monetary payment in exchange for land – a business transaction most often referred to in the literature as the problem of land assembly. To avoid the holdout problem which is a...

We characterize the boundaries of the set of transfers (extremal transfers) implementing a given allocation rule without imposing any assumptions on the agentʼs type space or utility function besides quasi-linearity. Exploiting the concept of extremal transfers allows us to obtain an exact...
