In this paper, we seek to adapt the analysis of Moshini et al by proosing a block structure for the price parameter matrix. This approch is slightlymore restrictive in terms of constraining the substitution effects in a s ingle level demand system, and so conserves further degrees of freedom.

There are still problems in handling diversity in economics. The general equilibrium model itself lacks determinacy for a generic population of economic agents. In an ourstanding contribution, Jean-Michel Grandmont (1992) argues that increasing behavioural heterogeneity makes aggregate...

Pashardes (1991) and Banks, Blundell and Preston (1994) use parametric methods to estimate lifetime equivalence scales. Their approaches put parametric restrictions on the differences in within-period expenditure needs across household types, the intertemporal allocation of expenditure, and the...

This paper uses experimental econoic methods to present evidence that the absence of a negative effect on demand in reaction to products containing GMO's is in large measure due to the fact that customers do not notice the labelling.

This paper presents and investigates two classes of equivalent-income functions that are generalizations of those that correspond to exact (independent-of-base) absolute and relative equivalence scales. They provide less restrictive household demands, especially for children's goods, and have...
