The purpose of his paper is to describe consumer behavior in the Czech Republic by estimating a demand system in which demand depends on income and prices, but also on other factors such as age, size of the household, and position on the labor market. We combine Household Budget Survey data with...

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors, spanning the space of Engel curves. Once the common factors are estimated via approximate principal components, we identify them by imposing...

The share of household resources devoted to children is hard to identify, because consumption is measured at the household level, and goods can be shared. Using semiparametric restrictions on individual preferences within a collective model, we identify how total household resources are divided...

This article presents and estimates demand systems by explicitly incorporating intertemporal consumption behavior as summarized by the Euler equation. Demand systems are characterized by two indirect utility functions which are effectively globally regular and can better approximate nonlinear...

This paper develops a model for demand-system estimations, whose coefficients are own-price Marshallian elasticities and elasticities of substitution between goods. The model satisfies the homogeneity, symmetry and, eventually, adding-up restrictions implied by consumer theory, and is primarily...

This paper shows that a power utility specification of preferences over total expenditure (ie. CRRA preferences) implies that intratemporal demands are in the PIGL/PIGLOG class. This class generates (at most) rank two demand systems and we can test the validity of power utility on cross-section...

This article uses the hedonic approach to estimate how much is paid for the energy efficiency label on the dishwasher market in Spain. The estimated figure is 15.6% of the final price. This accounts for about 80€ of the average price. We use this estimate combined with a demand systems to...

Using household data from the 2006 Income and Expenditure survey, we providea new estimation of demand systems for Colombia. We estimate three differentspecifications of demand systems, namely, the Linear Expenditure System(LES), the Extended Linear Expenditure System (ELES) and the Almost...
