Última Innovation Systems and Technical Efficiency in Developing-Country Agriculture AgEcon Mekonnen, Dawit Kelemework; Spielman, David J.; Fonsah, Esendugue Greg. The paper uses a stochastic frontier analysis of production functions to estimate the level of technical efficiency in agriculture for a panel of 29 developing countries in Africa and Asia between 1994 and 2000. In addition, the paper examines how different components of an agricultural innovation system interact to determine the estimated technical inefficiencies. Results show that the mean level of technical efficiency among the sampled countries was about 86 percent, with some modest increases during the period in question. These results suggest that there is room for significant increases of production through reallocations of existing resources. Despite significant variation among countries, these results also indicate quite a number of least...

Ano: 2012 URL: http://purl.umn.edu/119788 Demand Estimation for US Apple Juice Imports: A Restricted Source Differentiated AIDS Model AgEcon Mekonnen, Dawit Kelemework; Fonsah, Esendugue Greg. Although this paper focuses on apple juice, a restricted version of source differentiated Almost Ideal Demand System (RSDAIDS) was used to examine U.S. import demand for fresh apple, apple juice and other processed apple. Apple imports were differentiated by type and source of origin and the RSDAIDS model was estimated after imposing the general demand restrictions of adding-up, homogeneity and slutsky symmetry. Seasonality and trend variables were also included on the model. The estimation results showed that U.S. demand for apple juice from China was price inelastic with relatively high expenditure elasticity. We believe the result partially explains why China managed to have a 60 percent import market share in the sub-market despite U.S. imposition of...

Ano: 2011 URL: http://purl.umn.edu/98789 Analysis of Fruit Consumption in the U.S. with a Quadratic AIDS Model AgEcon Mekonnen, Dawit Kelemework; Huang, Chung L.; Fonsah, Esendugue Greg. The Quadratic AIDS model was estimated to analyze the U.S. fruit consumption using annual per capita consumption data and prices for a demand system consisting of fresh fruit, fruit juice and other processed fruit. All Marshallian own price elasticities are found to be negative and the demand system is dominated by complementarity relationships. Both own and cross price Marshallian elasticities are less than one. Fruit juices are found to be expenditure elastic conditional on the total expenditure on fruits while fresh fruits and other processed fruits are found to be expenditure inelastic. However, fresh fruit is close to being unitary expenditure elastic. After allowing for curvature in the Engel function, U.S. fresh fruit demand is found to be more...
