Ausgaben- und Preiselastizitäten der Nahrungsmittelnachfrage auf Basis von Querschnittsdaten: Eine Systemschätzung für die Bundesrepublik Deutschland AgEcon
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...

Impacts of Sample Size and Quality-Adjusted Imputed Prices on Own-Price Elasticities Estimated Using Cross-Sectional Data AgEcon
Stockton, Matthew C..
Cross-sectional data sets containing expenditure and quantity information are typically used to calculate quality-adjusted imputed prices. Do sample size and quality adjustment of price statistically alter estimates for own-price elasticities? This paper employs a data set pertaining to three food categories-pork, cheese, and food away from home-with four sample sizes for each food category. Twelve sample sizes were used for both adjusted and unadjusted prices to derive elasticities. No statistical differences were found between own-price elasticities among sample sizes. However, elasticities that were based on adjusted price imputations were significantly different from those that were based on unadjusted prices.

The Demand for Meats in Indonesia: A Censored Regression Approach AgEcon
Hutasuhut, Maradoli; O'Donnell, Christopher J.; Chang, Hui-Shung (Christie); Griffith, Garry R.; Doran, Howard E..
In this study, meat consumption and socio-demographic data from the 1990, 1993 and 1996 SUSENAS Household Food Expenditure and Consumption Surveys were employed to estimate the demand for meats in Indonesia. The provinces of DKI Jakarta and West Java were chosen as the areas of study because of the population, level of meat consumption and the availability and quality of information in these two provinces. Several statistical and econometric procedures were performed. Firstly, a cluster analysis (Nicol, 1991) was used to aggregate the 16 meat types recorded in the SUSENAS into four Meat Groups (MG-1, 2, 3 and 4). Secondly, a double truncation procedure was used to estimate the linear approximation of the Almost Ideal Demand System (LA/AIDS) because of the...
