| 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 switching mechanism is controlled by an unobserved variable that follows a Markov chain. As such, it captures more complex dynamic patterns than does the S-AIDS model. The MS-AIDS and the S-AIDS are compared to determine which model provides the better explanation of beef, poultry, and fish dynamic demand. We find that a MS-AIDS displaying habit formation detects the two mad cow crises in 1996 and 2000 and may identify the structural changes emanating from... |

| A number of public health advocates and consumer associations urge policy makers to strengthen nutrient labelling rules, in order to help people to make healthier and better informed food choices. Yet, little is known about the e¤ectiveness of mandatory labelling. This research evaluates the impact of a mandatory fat label policy on consumer choices in the fromages blanc and dessert yogurt market. While fat labels are mandatory since 1988 for fromages blancs, this is not the case for yogurts. This is a natural source of variation to identify separately consumer preferences for labels and for fat. We use a mixed logit discrete choice model and household scanner data collected in 2007 to estimate the distribution of the Willingness-To-Pay (WTP) for fat... |
