Optimal Lottery

Mardi | 2014-10-21 Sully 5, 16h00-17h20 Charles DENNERY – Alexis DIRER This article proposes an equilibrium approach to lottery markets in which a firm designs an optimal lottery to rank-dependent expected utility (RDU) consumers. We show that a fi nite number of prizes cannot be optimal, unless implausible utility and probability weighting functions are assumed. We then investigate the conditions under which a probability density function can be optimal. With standard RDU preferences, this implies a discrete probability on the […]

Ambiguous Life Expectancy and the Demand for Annuities

Mardi | 2014-10-14 Sully 5, 16h00-17h20 Emmanuel THIBAULT – Hippolyte D’ALBIS In this paper, ambiguity aversion to uncertain survival probabilities is introduced in a life-cycle model with a bequest motive to study the optimal demand for annuities. Provided that annuities return is sufficiently large, and notably when it is fair, positive annuitization is known to be the optimal strategy of ambiguity neutral individuals. Conversely, we show that the demand for annuities decreases with ambiguity aversion and that there exists a […]

Etude sur la non-linéarité entre croissance et endettement dans l’UEMOA

Mercredi | 2014-10-08 C002, 12h-14h Oumou GUISSE L’objectif de cet article est d’étudier la nature de la relation entre endettement extérieur et activité économique. L’étude se fait sur un panel constitué des pays membres de l’Union Économique et Monétaire Ouest Africaine (à l’exception de la Guinée Bissau) sur une période allant de 1972 à 2012. Différentes méthodologies ont été utilisées, parmi lesquelles le mécanisme de la transition brutale ou modèle PTR développée par Hansen (1999) mais aussi son extension en […]

A microsimulation framework for projecting public pensions’ sustainability. Simulating labour-market transitions and contribution years in Argentina

Mardi | 2014-09-30 Sully 5, 16h00-17h20 Leonardo Eric CALCAGNO Using a standard microsimulation framework, this paper intends to draw perspectives on Argentina’s pension system from a household-level quaterly survey data, the EPH. After describing the country’s current public Pay-As-You-Go pension system, this paper uses the country’s household survey’s labour market related data to describe and estimate transitions between labour market states for individuals of working age. Finally, together with demographic data provided by Argentina’s statistical body INDEC, we describe how […]

Spatial Dependence in the Persistence of Segregation and Poverty in the U.S. Urban South: the Houston case-study

Mardi | 2014-09-23 Sully 5, 16h00-17h20 Jean-Marc ZANINETTI – Craig E. COLTEN Concentrated poverty in highly segregated neighborhoods within U.S. metropolitan areas is a long debated academic issue. Studied in isolation, the usual statistical indicators may fail to locate accurately the most distressed neighborhoods and assess the exact relationship between places, race and poverty. This paper investigates the persistent linkage between the poverty rate at the neighborhood level and the spatial distribution of African-American and Hispanic communities by using spatially […]

Volatiliy During the Financial Crisis Through the Lens of High-frequency Data: A Realized GARCH Approach

Mardi | 2014-07-01 Salle des thèses Denisa BANULESCU-RADU – Peter Reinhard HANSEN – Zhuo HUANG – Marius² MATEI In this paper we study the financial volatility during the global financial crisis and use the largest volatility shocks to identify major events during the crisis. Our analysis makes extensive use of high-frequency (HF) financial data for the modelling of volatility and, importantly, for determining the timing within the day when the largest volatility shocks occurred. The latter helps us identify the […]

Evaluation des effets des politiques non conventionnelles à partir d’un modèle DSGE à deux pays

Mercredi | 2014-06-18 Salle B103, 12H00 A 14H00 Cet article vise à étudier les effets des politiques non conventionnelles dans un modèled’équilibre général dynamique stochastique (DSGE). Nous considérons le cas de deux payssoumis à la même politique monétaire mais différents dans les paramètres caractéristiquesdes économies. Cette dimension autorise des effets asymétriques de la politiques monétaire.Le modèle est composé de cinq agents : ménages, banques, entreprises, gouvernement et banque centrale. Il prend en compte la contrainte de bilan des intermédiaires financiers […]

Can a Platform Make Profit with Consumers’ Mobility? A Two-Sided Monopoly Model with Random Endogenous Side-Switching

Mardi | 2014-06-17 Sully 5 Pierre ANDREOLETTI – Pierre GAZE – Maxime MENUET We model a specific two-sided monopoly market in which agents can switch from a side to the other. We define two periods of time. In the first period, agents buy the platform services on each side and in the second period of time, they can possibly enhance their satisfaction by going to the other face of the platform. We analyze the link between mobility, consumer’s utility, prices […]
