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...

This paper examines whether large U.S. banks have become ''too big to innovate''. We extend the theoretical work of Aghion et al. (2005b) by relaxing their assumption that unit costs are independent from output levels in order to investigate the effect of scale (dis)economies on the...

We study a dynamic pricing problem for a company that sells a single product to a group of customers over a finite time horizon. These customers are price sensitive and the price of today influences the group of customers of tomorrow. The objective is to set the prices over time so as to...

We consider a stochastic scheduling problem which generalizes traditional stochastic scheduling by introducing parameter uncertainty. Two classes of independent jobs have to be processed by a single machine so as to minimize the sum of expected completion times. The processing times of the jobs...

We consider a stochastic scheduling problem in which there is uncertainty about parame-ters of the probability distribution of the processing times. We restrict ourselves to the setting in which there are two different classes of jobs. The processing times of the jobs are assumed to be...

We model a three-pillar pension system and analyse the impact of exogenous shocks on an open economy, using an overlapping generation model where individuals live for two periods. The three-pillar pension system consists of (1) a PAYG pension system, (2) a defined benefits pension fund, and (3)...

The performance of wireless networks suffers from collisions. These occur when multiplewireless nodes transmit simultaneously, and their signals interfere with each other. To reduce collisions, nodes may use a randomized protocol to regulate their behavior. An example of such a protocol is...
