This paper presents the results from estimating on Almost Ideal Demand System (AIDS) for fresh fruit in Portugal. A complete matrix of price and expenditure elasticities of demand for apples, pears, oranges, peaches, cherries and plums is reported. A Bayesian approach is used to impose curvature...

This paper reports an alternative approach to the estimation of aggregate production response. The principles of the nonparametric analysis of production data are outlined. The weak axiom of variable profit maximisation is introduced and used to define netput schedules. Data from the national...

A Bayesian method of estimating multivariate sample selection models is introduced and applied to the estimation of a demand system for food in the UK to account for censoring arising from infrequency of purchase. We show how it is possible to impose identifying restrictions on the sample...

In this paper, a modelling approach is developed for the treatment of ‘don't know’(DK) responses, within choice experiments (CEs). A DK option is motivated by the need to allow respondents the opportunity to express uncertainty. Our model explains a DK using an entropy measure of the...
