Choice of functional form and structural change specification may each influence demand parameter estimates. Joint non-nested testing of both is applied for the linearised almost ideal and Rotterdam models with and without structural change, incorporated using a gradual transition specification....

Non-compensatory preferences are investigated by incorporating attribute cutoffs into models of consumer choices for food with health-related attributes (omega-3 content) that may be associated with genetic modification. We find empirical evidence that some individuals tend to use attribute...

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...
