Working Paper Series Document de travail de la série RETAIL TOBACCO DISPLAY BANS
Bans on retail tobacco displays, of the type proposed by New York’s Mayor Bloomberg in March 2013, have been operative in several economies since 2001. Despite an enormous number of studies in public health journals using attitudinal data, we can find no population-based econometric studies of the type normally used in Economics. This paper attempts to fill that gap by using data from the annua...

The aim of this work is to bring an econometric approach upon the CO2 market. We identify the specificities of this market, and regarding the carbon as a commodity. We investigate the econometric particularities of CO2 prices behavior and their result of the calibration. We apprehend and explain the reasons of the non-Gaussian behavior of this market focusing mainly upon jump diffusion and gene...

The main contribution of the paper is to provide a weaker nonsatiation assumption than the one commonly used in the literature to ensure the existence of competitive equilibrium. Our assumption allows for satiation points in the set of individually feasible consumptions, provided that the consumer has satiation points available to him outside this set. As a result, we show the concept of equili...

Whether to keep products segregated (e.g., unbundled) or integrate some or all of them (e.g., bundle) has been a problem of profound interest in areas such as portfolio theory in finance, risk capital allocations in insurance, and marketing of consumer products. Such decisions are inherently complex and depend on factors such as the underlying product values and consumer preferences, the latter...

In a recent but well known paper, Reny has proved the existence of Nash equilibria for compact and quasiconcave games, with possibly discontinuous payoff functions. In this paper, we prove that the quasiconcavity assumption in Reny’s theorem can be weakened: we introduce a measure allowing to localize the lack of quasiconcavity, which allows to refine the analysis of equilibrium existence.
