The public-health community views the mandatory labelling and taxation of fat as promising tools to control the growth of food-related chronic disease. This paper is the first to propose an ex ante evaluation of these two policy options in an oligopolistic setting with differentiated products...

A time-varying coefficient demand system, the Markov switching almost ideal demand model, is proposed to shed new light on change over time in the structure of French meat and fish demand. The main feature of this model is that the switching mechanism from one structure of demand to the other is...

[eng] The capital asset pricing model for consumption cannot explain observed equity premiums unless disproportionate risk aversion coefficients are used. The equity premium puzzle has been attributed in particular to the time-separability of consumer preferences. This paper investigates...

Because food choices have important implications for human health and the environment, consumers are increasingly urged to modify their purchasing and eating habits so as to comply with a set of norms (e.g., eat at least five portions of fruits & vegetables a day; reduce meat consumption)....

This paper studies the empirical properties of introducing consumption complementarity and/or substitutability over time in a Lucas-style asset pricing model. Specifically, I investigate whether the model can replicate a selected set of observed U.S. asset return moments over the 1890-1999...

We investigate a non-linear representative consumer asset pricing model in a complete markets economy. The consumer is assumed to display time nonseparable preferences. The time nonseparability in preferences is due first to local substitution of consumption over time, and second to long-run...

This paper aims at simulating optimal prices satisfying public health recommendations in terms of nutrient adequacy. This implies to estimate a complete food demand system in order to compute price elasticities. Food consumption behaviors are described by an AI functional form [Deaton and...

Structural change in the French demand of beef, poultry and fish is originally investigated. Rather than applying the traditional switching AIDS (S-AIDS) model, we reconsider the analysis of structural change through the Markov switching AIDS (MS-AIDS). The main feature of this model is that the...
