The dispute between the US and EU over GM foods at the WTO is examined in terms of the issues it raises about protectionism, environmental protection and precaution. The issue of whether GM, GM Derived and Non-GM foods are equivalent to each other is examined using data from a national choice...

Widespread obesity in the U.S. is a relatively recent phenomenon, reaching epidemic proportions only in the last 15 years. However, existing research shows that while calorie expenditure through physical activity has not changed appreciably since 1980, calorie consumption has risen dramatically....

Modeling consumer choice in different areas has lead to an increase use of discrete choice models. Probit or Multinomial Logit Models are often the base of further empirical research of consumer choice. In some of these models the equations to solve have no closed-form expression. They include...

This paper examines the distribution of preferences in a sample of patients who responded to a discrete choice experiment on the choice of general practitioner appointments. In addition to standard logit, mixed and latent class logit models are used to analyse the data from the choice...

This paper analyses labour market outcomes of temporary workers in Europe. First, investigating if the labour market is segmented into heterogeneous clusters. Second, identifying the characteristics that are most likely to affect the contract types hold by workers Third, focusing on exits from...

Berry, Levinsohn, and Pakes (1995) developed an estimator for an equilibium model of differentiated products markets using aggregate data, without assuming the existence of a representative agent, or imposing prior restrictions on elasticities. Their estimator though, was computationally...

For the estimation of many econometric models, integrals without analytical solutions have to be evaluated. Examples include limited dependent variables and nonlinear panel data models. In the case of one-dimensional integrals, Gaussian quadrature is known to work efficiently for a large class...

In this note we investigate the empirical differences between the Random Utility model with fixed coefficients (Conditional Logit), and the Random Utility model with random coefficients (Mixed Logit). We consider a model of household labour supply developed for a project aimed at the evaluation...

Empirical and theoretical research on the demand for health inputs has been, and still is, extensive. However, much of the focus of discrete choice studies has been on the effects of various attributes on household choice of e.g. health care provider and little attention has been paid to...
