Cet article rend compte d'une recherche sur l'utilisation de la messagerie électronique (e-mail) dans la relation de contrôle hiérarchique. Trois caractéristiques de cette NTIC (caractère quasicontractuel, large diffusion et convivialité) expliquent que l'e-mail soit un outil de...

Advertising competes for scarce consumer attention, so more profitable advertisers send more messages to break through the others' clutter. Multiple equilibria can arise: more messages in aggregate induce more "shouting to be heard", dissipating profit. Equilibria can involve a small range of...

Conventional normative economics is built on the assumption that people act as if seeking to satisfy coherent and a priori preferences. This model has however been challenged by many empirical works highlighting the existence of systematic deviations from the behaviour predicted by the...

This paper focuses on intergenerational educational mobility in France using the "Generation 92" survey respectively for native children, first and second generation of immigrants. Drawing on ordered Probit models for educational attainment, we show that a high level of parental education has...

Ce papier présente un modèle macroéconomique qui associe étroitement théorie de la monnaie endogène et approche multi-agents. C'est un modèle décentralisé, peuplé d'agents multiples, hétérogènes, autonomes et concurrents qui interagissent simultanément dans les sphères réelle et...

This paper studies the potential commitment value of cheap talkinflation announcements in an agent-based dynamic extension of theKydland-Prescott model. In every period, the policy maker makesa non-binding inflation announcement before setting the actualinflation rate. It updates its decisions...

Inspired by the recent literature on aggregation theory, we aim at relating the long range correlation of the stocks return volatility to the heterogeneity of the investors' expectations about the level of the future volatility. Based on a semi-parametric model of investors' anticipations, we...

We investigate subjective reactions when subjects realize they have been victims of framing-effects in situations of risky choices - that is, when they violated the invariance principle in decision-theory. We try to assess various explanations of this violation in terms of bounded rationality...

We define continuous-time dynamics for exchange economies with fiat money. Traders have locally rational expectations, face a cash-in-advance constraint, and continuously adjust their short-run dominant strategy in a monetary strategic market game involving a double-auction with limit-price...

This paper presents a computational macroeconomic model which closely associates Keynesian thinking and an agent-based approach. This model is original because we do not introduce any causality between macroeconomic variables. Instead of postulate macroeconomic properties, we want to understand...
