This paper deals with different concepts of income elasticities of demand for a heterogenous population and the relationship between individual and aggregate elasticities is analyzed. In general, the aggregate elasticity is not equal to the mean of individual elasticities. The difference depends...

The paper uses micro cross-section data from the GfK consumer panel for econometric demand analysis of private households in Germany. Contrary to most research which considered "average" behavior we extend this approach to consumer behavior for different "intensities" of consumption. Our...

This paper analyzes the wealth effect on consumption in France by relying on two original household surveys. First, it provides the first estimate of the marginal propensity to consume out of wealth based on micro data for France (Enquête Patrimoine 2009, Insee): a low but significant wealth...

Recent advances in the collective model literature suggest ways to estimate the complete allocation of resources within households, using assignable goods and assuming adult preference similarity across demographic groups (or across spouses). While it makes welfare analysis at the individual...

This paper studies the Engel’s relationship for the consumption of food away from home (FAFH) in Argentina. Different Engel curves and their respective expenditure elasticities are estimated, including socio-economic and demographic characteristics of households, and later computing the...

Berkson errors are commonplace in empirical microeconomics and occur whenever we observe an average in a specified group rather than the true individual value. In consumer demand this form of measurement error is present because the price an individual pays is often measured by the average price...

Consumer demand microdata typically exhibit a great deal of expenditure variation but not very much price variation. In this paper, we propose a semiparametric approach to the consumer demand problem in which expenditure share equations are nonparametric in the real expenditure direction and...

We propose a method to quantify other-regarding preferences in group decisions. Our method is based on revealed preference theory. It measures willingness-to- pay for others’ consumption and willingness-to-pay for equality in consumption by evaluating consumption externalities in monetary...

Consumption based equivalence scales are estimated by applying the extended partially linear model (EPLM) to the 1998 Income and Consumption Survey (EVS) carried out in Germany. In this model the equivalence scales are identified by virtue of nonlinearities in household demand. Therefore, the...
