This paper sheds light on the role of student motivation in the success of schooling. We develop a model in which a teacher engages in the management of student moti- vation through the choice of the classroom environment. We show that the teacher is able to motivate high-ability students, at...

A long-standing question in biology and economics is whether individual organisms evolve to behave as if they were striving to maximize some goal function. We here formalize the \as if" question in a patch-structured population in which individuals obtain material payoffs from (perhaps very...

In this paper, we evaluate the impact of foreign fees, paid by consumers when they withdraw cash at banks that are not their own, on their withdrawals. We take advantage of a natural experiment whereby (non linear) payment fees for withdrawing cash at foreign ATMs were introduced at one point in...

We study the political determination of the level of social long-term care insurance when voters also choose private insurance and saving amounts. Agents di§er in income, probability of becoming dependent and of receiving family help. Social insurance redistributes across income and risk...

The effect of consumers’ compliance with nutritional recommendations is uncertain because of potentially complex substitutions. To lift this uncertainty, we adapt a model of consumer behaviour under rationing to the case of linear nutritional constraints. Dietary adjustments are thus derived...

I propose a new theoretical framework to assess the approximate validity of overidentifying moment restrictions. Their approximate validity is evaluated by the divergence between the true probability measure and the closest measure that imposes the moment restrictions of interest. The divergence...

This paper investigates the collective choice of production standards by farmer and pro- cessor groups within a vertical food supply chain, taking into account their competition behaviors. In a context in which raising standards cannot translate into a direct price premium to consumers, we...

Individuals, differing in productivity and life expectancy, vote over the size and type of a collective annuity. Its type is represented by the fraction of the contributive (Bismarckian) component (based on the workers past earnings) as opposed to the non- contributive (Beveridgean) part (based...

Market fragmentation and technology have given rise to new trading strategies. One of them is to supply liquidity simultaneously across multiple trading venues, which requires multi-venue management of inventory risk. We build an inventory model in which order ow fragments across two venues, and...
