We study the role of monotonicity in the characterization of incentive compatible allocation rules when types are multi-dimensional, the mechanism designer may use monetary transfers, and agents have quasi-linear preferences over outcomes and transfers. It is well-known that monotonicity of the...

The classical bankruptcy problem (O''Neill, 1982) is extended by assuming that the agents have non-homogenous preferences over several estates. A special case is the one in which there are finitely many estates and the agents have homogenous preferences, i.e., constant utilities, per estate. In...

We prove that every multi-player Borel game with bounded and lower-semi-continuous payoffs admits a subgame-perfect epsilon-equilibrium in pure strategies. This result complements Example 3 in Solan and Vieille (2003), which shows that a subgame-perfect epsilon-equilibrium in pure strategies...

This paper investigates the effectiveness of an employment program exclusively run by and in a private sector firm, in order to find out whether a private program without cream-skimming can be beneficial to (a) the individual private firm and (b) society at large by outperforming public...

We study a spatial model of party formation in which the set of agendas is the unit circle. We characterize the sets of pure-strategy Nash equilibria under the plurality and proportional rules. In both rules, multiple configurations of parties are possible in Nash equilibrium. We refine our...

This paper introduces a new generation of Early Warning Systems (EWS) which takes into account dynamics within a system composed by binary variables. We elaborate on Kauppi and Saikonnen (2008), which allows to consider several dynamic specifications and to use an exact maximum likelihood...

In this paper we formalize the notion of lexicographic belief hierarchies in standard partitional models (Aumann, 1976). We introduce the notion of epistemic equivalence between two belief space, and show that the state space representation of lexicographic belief hierarchies is equivalent to...

Suppose that a firm has several owners and that the future is uncertain in the sense that one out of many different states of nature will realize tomorrow. An owner''s time preference and risk attitude will determine the importance he places on payoffs in the different states. It is a...

We propose a new model to study the role of commitment as a sourceof strategic bargaining power. Two impatient players bargain aboutthe division of a pie under a standard bargaining protocol indiscrete time with time-invariant recognition probabilities.Instantaneous utility is linear, but...

This paper proposes a new statistical framework originating from the traditional credit-scoring literature, to evaluate currency crises Early Warning Systems (EWS). Based on an assessment of the predictive power of panel logit and Markov frameworks, the panel logit model is outperforming the...
