This paper explores the link between accountability, corruption and efficiency in the context of a career concern model where politically con- nected local monopolies are in charge of the provision of a local public service. We fi?nd that both corruption and a low degree of accountabil- ity...

The paper investigates the link between corruption and efficiency by using a rich micro-level dataset concerning solid waste collection activities in 529 Italian municipalities observed over the years 2004-2006. In order to test the impact of corruption on cost efficiency we estimate a...

In this paper we consider the classical problem of dividing a land among many agents so that everybody is satisfied with the parcel she receives. In the literature, it is usually assumed that all the agents are endowed with cardinally comparable, additive, and monotone utility functions. In many...

Using data from the Continuing Survey of Food Intake by Individuals, this pa- per describes the shape of consumption profiles over the month for Social Security benefit recipients. Individuals with income mostly made up of Social Security ben- efits and who have some savings smooth consumption...

Language is arguably a powerful coordination device in real-life interactions. We here develop a game-theoretic model of two-sided pre-play communication that generalizes the cheap-talk approach by way of introducing a meaning correspondence between messages and actions, and postulating two...

We study the cores of non-atomic market games, a class of transferable utility co- operative games introduced by Aumann and Shapley [2], and, more in general, of those games that admit a na-continuous and concave extension to the set of ideal coalitions, studied by Einy, Moreno, and Shitovitz...

The paper considers an agent who must choose an action today under uncertainty about the consequence of any chosen action but without having in mind a complete list of all the contingencies that could influence outcomes. She conceives of some relevant (subjective) contingencies but she is aware...

We report a surprising link between optimal portfolios generated by a special type of variational preferences called divergence preferences (cf. [8]) and optimal portfolios generated by classical expected utility. As a special case we connect optimization of truncated quadratic utility (cf. [2])...

We study the updating of beliefs under ambiguity for invariant biseparable preferences. In particular, we show that a natural form of dynamic consistency characterizes the Bayesian updating of these beliefs.
