A two-stage gravity-based model is used to explain cattle and beef bilateral trade flows between 42 countries. The model parameters are estimated using a double-hurdle model with a multivariate sample selection procedure. The parameter estimates are used to simulate probabilities of new trade...

Biotechnology has had an important impact on the agricultural and food industries over the last 12 years by way of fast and extensive adoption of a few genetically modified (GM) crops. This has produced large efficiency gains, including higher yields and reduced costs of weed and pest control,...

We address the issue of structural change in demand analysis. After a brief discussion of the major problems and questions that arise in this context, the main body of the paper is devoted to a review of analytical methods that are relevant to investigating structural change in demand. This...

We develop a reputation model to study the concurrent use of trademarks and certification for food products with a geographical indication (GI). The model extends Shapiro's (1983) approach to modelling reputation to a situation in which two technologies for the production of quality are...
