This study estimated a set of unconditional own-price and expenditure elasticities for 49 processed food categories using scanner data and the FAST multistage demand system. Overall, our estimated own-price and expenditure elasticities are generally much larger, in absolute terms, than previous...

A normalized quadratic input distance system is applied to estimate inverse demand relationships for wheat by class. Semi-nonparametric and Bayesian estimators are used to impose curvature on inputs and outputs. Price flexibilities are estimated for hard red winter, hard red spring, soft red...

Several recent papers report a puzzling pattern of food demand falling as household size rises at constant per capita expenditure, especially in poorer countries. This pattern is contrary to a widely used model of scale economics. This paper exploits within-country differences in household...

Fresh tomatoes are highly differentiated products: greenhouse and on-the-vine tomatoes are the most prominent new kinds of tomatoes. Scanner data were used to estimate a weakly separable, quadratic almost-ideal demand system. Uncompensated elasticities indicate (a) considerable own-price...

An LA/AIDS model is developed to estimate demand elasticities for packages of 8-oz shredded cheese for higher- and lower-income consumers. Data used in this study are scanner data for six supermarket stores in two distinct socioeconomic areas. Results show that: (1) lower-income shoppers are...

This paper assesses the independent and joint impacts of oligopoly power of market intermediaries and the Northeast Dairy Compact (NEDC) on fluid milk prices in Boston. Empirical results reveal that price increases due to oligopoly power far outweighed those caused by the NEDC by more than 10...

Detailed data from 3,500 urban Chinese households are used to estimate demand elasticities and the impacts of regional and demographic variables for 17 food products through a two-stage budgeting procedure with complete demand systems. Results suggest that China's food consumption patterns will...

Using a monthly data covering from 1974:1 to 2002:12, this paper explores the linkage between changes in macroeconomic variables (real exchange rate and inflation rate) and changes in relative agricultural prices in different time horizons (1, 12, 24, 36, 48, and 60 months). Controlling for...

In 1991, mandatory warning labels were imposed on the sale of oysters harvested from the Gulf of Mexico. Using an IAIDS model, this paper investigates the impact of these labels on the demand for Gulf product as well related oyster products (the Chesapeake, the Pacific, and imports).
