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 […]

What Happens when Gamblers Get their Hands on Money? Lottery-type Stocks at the Turn of the Month

Mardi | 2014-06-10 Salle des thèses Yun (Eric) MENG – Cristos PANTZALIS Lottery-type stocks outperform the rest at the turn of the month. This effect is particularly pronounced among firms located in areas whose demographic profile resembles that of the typical lottery-ticket buyers (i.e. gamblers) and partially driven by the within-month cyclicality of local investors’ personal liquidity positions. Consistent with the notion that gambling is associated with inattention, we find underreaction to earnings news issued by lottery-type firms located in […]

Public Debt, Life Expectancy and the Environment (Article en attente)

Mercredi | 2014-05-28 Salle B103 The objective of the present paper is to give some policy recommendations to improve environmental quality in a context of debt consolidation. For that purpose, we develop an overlapping generation model in which we include public debt and we modelize the two-way causality between life expectancy and the environment. We find that a voluntarist environmental policy may allow a country to escape the environmental poverty trap, or may help a country to reach a higher […]

A Microsimulation Framework for Projecting Public Pension’ Sustainability. Simulating Labour-Market Transitions and Contribution Years in Argentina

Mercredi | 2014-05-21 Salle B103 – 16h20 Leonardo Eric CALCAGNO Using a standard microsimulation framework, this paper intends to draw perspectives on Argentina’s pension system from a household-level quarterly survey data, the EPH. After describing the country’s current public Pay-As You-Go pension system, this paper uses the country’s house-hold 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 […]

Stability and Identification with Optimal Macroprudential Policy Rules (version 1)

Mardi | 2014-05-13 Salle des thèses Jean-Bernard CHATELAIN – Kirsten RALF This paper investigates the identification, the determinacy and the stability of ad hoc, ”quasi-optimal” and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest rates, when the central bank precommits to financial stability. Firstly, ad hoc and quasi optimal rules parameters of financial stability indicators cannot be identified. For those rules, non zero […]
