“…How different are the new estimates from existing ones? For example Tshikala and Fonsah (2012) found cantaloupe to be less price-inelastic (20.77) compared with the estimates (20.52, 20.05, 20.18, and 20.16) derived by the authors. However, this difference is more related to the fact that Tshikala and Fonsah used aggregated U.S. import data, whereas the authors used U.S. imports disaggregated by the individual countries from which the U.S. is importing.…”

Remarkable changes have occurred over the years in the domestic and international economic environment of the fruit and vegetable industry. These changes are partly driven by the North American Free Trade Agreement, nutrition policies, and development and enforcement of new food safety standards. The articles in this invited session examined the effect of these drivers and their implication on the future competitiveness of the southern fruit and vegetable industry.

“…Yang & Koo (1994) extended the AIDS model to estimate source-differentiated demand systems without all of the restrictions of the Armington system. Several studies have used this model to estimate price elasticities of demand for imported commodities from different exporting countries (Henneberry & Hwang, 2007;Tshikala & Fonsah, 2012;He, 2019;Mnatsakanyan & Lopez, 2019;Lee et al, 2020;Ning et al, 2021;Zhang et al, 2021). We also used the source-differentiated AIDS model to estimate the own-price, cross-price, and income elasticities of imported melons in China from Vietnam, Myanmar, and ROW.…”

“…The equation for ROW was removed from the analysis and its coefficients were calculated using the summation condition. After the LA-AIDS model was estimated, the coefficients were transformed to both Marshallian and Hicksian elasticities following past literature (Mdafri & Brorsen, 1993;Taljaard et al, 2004;Tshikala & Fonsah, 2012):…”

“…The absolute value of the conditional Marshallian (uncompensated elasticities) and the Hicksian or compensated elasticities for both Vietnam and Myanmar were near or above one indicating their demand as being price-elastic (Taljaard et al, 2004;Tshikala & Fonsah, 2012) while holding melon expenditures constant. The own-price Marshallian elasticities of melons had negative signs, and all were statistically significant.…”

Vietnam and Myanmar are major exporters of melons (Citrullus lanatus) to China. Among all fresh fruits, melons account for Myanmar’s and Vietnam’s largest export volume and values. Over 90% of Myanmar’s melons are exported via border trade, primarily to China. Measuring the own- and cross-price elasticities of imported melons into China that come from Vietnam and Myanmar can help each exporter understand the market potential for their melons. The objective of the study was to estimate the own- and cross-price elasticities of imported melons into China differentiated by exporting country. The demand system of imported melons into China was estimated using a source-differentiated Linear Approximation of the Almost Ideal Demand System (LA-AIDS). The results suggest that imported melons are weakly separable from other imported fruits. While melons from Vietnam and Myanmar are substitutes for each other, the price of melons from the rest of the world (ROW) did not have a significant effect on China’s imports of melons from Vietnam or Myanmar. The estimated coefficients from the seasonal dummy variables included in the demand equations show little seasonality in the market shares of Vietnam, Myanmar, and the ROW for melon imports to China.

O consumo de carnes no Brasil passou por uma grande expansão nas últimas décadas, passando de 27kg para 97kg anuais per capita num espaço de pouco mais de 40 anos. A mudança da estrutura de produção ocorrida ao longo do tempo fez com que os preços das carnes diminuíssem, tendo com uma das consequências o aumento do consumo de carne por parte da população brasileira. O objetivo do presente trabalho é estimar a demanda familiar de carnes bovina, suína e de frango no Brasil. São utilizados dados de preços do Instituto de Economia Agrícola e consumo do United States Department of Agriculture no período de 1970 a 2015. Foram também estimadas as elasticidades-gasto, elasticidades-preço da demanda e elasticidades-preço cruzadas da demanda. A metodologia do trabalho baseia-se no sistema linear de demanda quase ideal (LA-AIDS). A evolução dos preços, assim como as elasticidades apresentadas mostram que as carnes bovina, suína e de frango são bens normais e que existe uma forte relação de substituibilidade entre as carnes bovina e de frango e entre as carnes suína e de frango. Além disso, existe uma relação relativamente fraca de complementariedade entre as carnes bovina e suína.
