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...

The aim of this paper is to overcome the problems caused by insufficient price variation in estimating a large demand system. For that, we propose a new form of Stone-Lewbel (SL) cross section prices developed under latent separability that explore individual specific variation in the...

The aim of this paper is to propose an analytical framework, wherein the individuals' choice problem is addressed in terms of alternative time‐consuming activities rather than in terms of alternative bundles of goods and services. In particular, the paper reverses Becker's (1965) proposal to...

This work tries to provide a path to describe the modern marketing research and, at the same time, it tries to examine carefully in which context, a firm can be supported by marketing strategies focused to the consumers. Between different methods examined, the Conjoint analysis has resulted the...

Using method of Lagrange multipliers, an attempt has been taken in this paper to derive mathematical formulation to devise optimal purchasing policy in order to maximize utility function subject to multiple constrained, in this particular illustration, two constraints: 1) budget constraint, and...

After a deep review of the main economic studies and applications about the emerging problem of obesity, this paper focuses on a particular aspect of the issue: the improvement of fruit and vegetable purchasing in retailing sector. First of all it has been analyzed the actual presence of...

This paper presents an experiment, which builds a bridge over the gap between neuroscience and the analysis of economic behaviour. We apply the mathematical theory of Pavlovian conditioning, known as Recurrent Associative Gated Dipole (READ), to analyse consumer choices in a computer-based...

The paper highlights the need for a methodological framework on which to base projections in project appraisal applications. Following an initial definition and sizing of the relevant market of the project, the market is analysed in terms of which are the main customer groups, what their needs...

This paper attempts to explore the nature of the goods in a Two Commodity world. The analysis suggests that the only possibility that the two goods have same income elasticity is the case when both goods have unit income elasticities. Moreover, if both the goods have equal income elasticities,...
