We study the testability implications of public versus private consumption. The distinguishing feature of our approach is that we start from a revealed preference characterization of collectively rational behavior. Remarkably, we find that assumptions regarding the public or private nature of...

The inclusion of time in the household domestic production function allows to calculate full prices that are in turn used to estimate consistent monetary and time elasticities on micro cross-sectional data. This article provides elasticity estimates for different commodity groups in absence of...

In this article, we propose a new method to estimate price effects on micro cross-sectional data using full prices that take into account household domestic production. We use behavioral microsimulations by subpopulations to analyze the redistributive impact of changes on Value Added Tax (VAT)...

This article uses household data to measure the substitutability between time and money for eight commodity groups and different countries. The elasticities estimated using the household's market wage and an estimated opportunity cost of time are positive, indicating substitutability, and much...

This paper proposes a new theory of social norms that explores the relation between individuals' income, time allocation decisions, and consumption choices on the one hand, and the determinants of individuals' decision to conform or not to social norms on the other. It is shown that rational...

This paper proposes a new formulation of the theory of social norms. The theoretical model explores the interrelation between individuals' income, time-use and consumption decisions on the one hand, and the determinants of their decision to conform or not to social norms on the other. It is...

This paper contributes to the discussion of the compatibility of consumers' behavior in "real" life with GARP. Within expenditure panel data we observe a relatively low rate of violation (240 out of 3630 households). We show that these violations do not imply an "irrational" behavior of the...

We reformulate Grandmont's and its successors' notion of behavioral heterogeneity such as to get the exact insensitivity of the aggregate budget share function with respect to changes in prices and income, instead of a mere approximate insensitivity. We propose a non parametric set-up such that,...
