Última Ausgaben- und Preiselastizitäten der Nahrungsmittelnachfrage auf Basis von Querschnittsdaten: Eine Systemschätzung für die Bundesrepublik Deutschland 31 Thiele, Silke. This study presents a procedure to estimate expenditure and price elasticities of food commodities from cross-sectional data. There are two problems with the use of cross-sectional data: First, priceinformation is not sufficient in these data. To derive “adjusted prices” from cross-sectional data an approach of COX and WOHLGENANT is applied. Second, zero expenditures for some commodity groups can be observed. To avoid selectivity bias a generalization of the HECKMAN procedure is employed. Both, the adjusted prices and the bias correction are included in a Linear Expenditure System. It can be concluded that expenditure and price elasticities could differ significantly between household characteristics. The research results suggest that attempts to use only...

This study examines the various factors affecting household expenditure on fresh and processed fruit and vegetables in the U.S. using the 1992 Consumer Expenditure Survey. Empirical results suggest that higher income, better educated, larger, and older households spend more on fresh and processed fruit and vegetables than do other households. Seasonal and regional variations are also evident.
