We estimated the impact of the Indian tariff on the demand for imported fresh apples from theUnited States. A 1% decrease in the tariff would increase the quantities demanded by 3.83%. If India eliminates the tariff on all imported fresh apples, total consumer welfare in terms of the imported fresh apple market will increase by $120 million yearly, 57% of the value of all fresh apples imported by India in 2015. This study adds evidence on the effects of tariff reduction on trade volume and welfare of consumers in the importing country.

Organic food products, which have been sold traditionally at natural food stores, have become increasingly available through mass marketing channels. This study estimated an almost ideal demand system (AIDS) model using 2008–2010 retail scanner data to examine consumer demand for organic fluid milk products sold at conventional and natural marketing channels. Asymmetric cross-price elasticities were found suggesting relative stickiness in demand to switch from organic milk to conventional milk and from natural stores to food, drug, and mass merchandiser stores. More generally, demands shifting toward products with higher expenditure elasticities in a differentiated market can be explained by relative budget shares and expenditure elasticities.

A two-stage budgeting LES-LA/AIDS system is used to estimate rural household demand in China with special emphasis on changes in demand for fruit and vegetable commodities across different income groups. The own-price elasticity for food was found to be more elastic than that for clothing, housing, durable goods, and other items. Within the food group, price elasticities range from –1.042 to –0.019. Grain, with an expenditure elasticity of almost unity, is an important staple food for the average rural household. Vegetables are important nonstaple foods relative to fruits. Lower value vegetables are the most price elastic in the vegetable group. Fruits are more price elastic than vegetables, with grapes being the most price elastic. Different income groups share a common demand function.

Indonesia is a rapidly growing and competitive market for U.S. fruit. A restricted, source-differentiated, almost ideal demand system is estimated for apples, oranges, grapes, and other fruit in Indonesia. The Marshallian expenditure elasticities for U.S. fruit are estimated to be between 1.01 and 1.21. For grapes and oranges, competition with other fruits appears to be more important than competition with other supply sources. For apples, strong sourcedifferentiated substitution relationships are found.

The impacts of economic and demographic variables on the demand for food grain commodities in urban Jiangsu province of China are estimated, using both the QUAIDS and the AIDS models. Results show that the demands for wheat flour and coarse grains are price-elastic while the demands for rice and grain products are price-inelastic. Certain demographic variables show as having a significant impact on food grain demand. Finally, a decomposition of causes of changes in rice consumption over the period of 1995-2007 is performed.
