A source-differentiated analysis of tropical fresh fruit imports AgEcon
Nzaku, Kilungu; Houston, Jack E.; Fonsah, Esendugue Greg.
A source-differentiated Almost Ideal Demand System model is used to analyze U.S. demand for the major tropical fresh fruit imports from different countries of origin. The tropical fresh fruits chosen for analysis include fresh bananas, fresh pineapples, papayas, and mangoes/guavas. To address endogeneity problem, we utilized an iterative 3SLS estimation method. Results show that consumer incomes are a major determinant of tropical fresh fruit import demand and most of the tropical fresh fruit imports are luxury commodities. U.S. consumers have a preference for Guatemalan and Costa Rican bananas, Costa Rican and Honduras pineapples, and Ecuador and Mexican mangoes. A competitive relationship exists between bananas from Ecuador and Colombia, Ecuador and...

A Three-Year Study on the Effect of Trellis Type on Yield, Fruit Size, and Economics of Blackberry Production in Georgia AgEcon
Krewer, Gerard; Fonsah, Esendugue Greg; Boyhan, George.
Tissue-culture propagated "Chicksaw" blackberry plants were set four feet apart in April of 2000 as part of a five-year trellising trial near Reidsville, Georgia. There were five treatments: an untrellised control, posts with plastic baling string on both sides, posts and three vertical wires, "raspberry" V trellis, and Limited Arm-Rotation Shift-Trellis (eliminated in 2003). There were four replications with twenty feet for each treatment per replication, for a total of 80 feet per treatment. Primocanes were tipped at 3.5 to four feet and re-tipped several times during the summer when new growth exceeded about 12 inches. Mature plant height at the end of the growing season was about five feet. Starting in the third growing season, yield data was collected...

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...

Analysis of U.S. Demand for Imported Melons using a Dynamic Almost Ideal Demand System AgEcon
Kaninda Tshikala, Sam; Fonsah, Esendugue Greg.
Melons constitute an important part of the U.S. fruit and vegetable industry even though they are produced only from May through December of each year. Import supplies from Latin American countries are used to make up for the domestic demand shortages. This paper investigates the U.S. demand for imported fresh and frozen melons using quarterly data on import volumes and unit prices. A static and a dynamic linear approximated almost ideal demand systems were estimated using ITSUR. Marshallian and Hicksian elasticities were used to analyze consumers’ responsiveness to price and income change in the short run and the long run.

BANANA CULTIVAR TRIALS FOR FRUIT PRODUCTION, ORNAMENTAL-LANDSCAPE USE, AND ORNAMENTAL-NURSERY PRODUCTION IN SOUTH GEORGIA AgEcon
Fonsah, Esendugue Greg; Krewer, Gerard; Rieger, Mark.
North America is the largest net importer of bananas on a regional basis. The United States is still the world’'s number- one importer and consumer of bananas. U.S. companies spend approximately $1.1 billion each year on banana imports, purchasing 31.1% of total world imports (Fonsah 2002; FAO 2001). Bananas and plantains together have been rated the fourth most important crop in the world in terms of food value and food security. This research is aimed at determining the feasibility and suitability of Annual Cropping Production (ACP) for a niche market under Georgia weather conditions and, determining which cultivars have the greatest potential for ornamental-landscape use and ornamental-nursery production. Phenological and pomological sampling and data...

Banana Trials: A Potential Niche and Ethnic Market in Georgia AgEcon
Fonsah, Esendugue Greg; Krewer, Gerard; Wallace, Richard; Mullinix, Ben.
Annual cropping production (ACP) is a technique used worldwide to target favorable market conditions. This technique has allowed commercial banana production outside the traditional production belt such as South Africa, Thailand, Israel, and China. In 2003 an evaluation of thirty-three cultivars was initiated near Savannah, Georgia to determine their suitability for ornamental, nursery, and ACP for niche/ethnic markets under Georgia weather conditions. In South Georgia and other temperate regions around the world, the pseudostems are normally killed to ground level during most winters. However, excellent plant growth rate, good flowering, and limited commercial fruit production was observed. Identifying one or more cultivars with potential to produce...

Competiveness of Latin American Exports in the U.S. Banana Market AgEcon
Muhammad, Andrew; Fonsah, Esendugue Greg; Zahniser, Steven.
U.S. banana demand differentiated by country of origin is estimated using the generalized dynamic Rotterdam model. Results indicate that dynamic factors play a significant role in determining the allocation of U.S. banana expenditures across exporting sources. Of particular interest is Guatemala’s increased share and Costa Rica’s decreased share of U.S. banana supply. A number of factors explained why Guatemala replaced Costa Rica as the leading U.S. supplier in 2007. (1) Guatemala is the least expensive source on average. (2) Habit persistence, adjustment costs, and other dynamic factors favor Guatemala’s exports. (3) Given increases in the relative price of Costa Rica’s bananas, the price competition between Costa Rica and Guatemala is highly...

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...

Feasible Fumigant-Herbicide System Alternatives to Methyl Bromide for Bell Pepper Producers AgEcon
Byrd, Mark M.; Escalante, Cesar L.; Fonsah, Esendugue Greg; Wetzstein, Michael E..
With the current methyl bromide (MeBr) system for producing Georgia’s peppers being phased out, alternative fumigant and herbicide systems for producers are analyzed. Using stochastic dominance analyses, two alternatives exceeding MeBr’s yield and financial efficiency were identified. A programming model, incorporating simulation-optimization techniques, generated optimal production and financial plans. Results indicate potential economic viability under alternative systems vis-à-vis the traditional MeBr production system. The Telone II and Chloropicrin combination with Metham potassium may offer a viable substitute for MeBr.

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...

INTEGRATED QUALITY-CONTROL MANAGEMENT STRATEGIES IN BANANA PRODUCTION, PACKAGING, AND MARKETING AgEcon
Fonsah, Esendugue Greg.
Globally, banana and plantain is the fourth most important crop in terms of food value. In some Central American and Asian countries banana production has become a major source of export earnings. Some countries, especially the Francophone West Africa, have acknowledge its commercial importance and capitalized on the special relationship accorded them by the Lome Convention to produce and export bananas to France and other EU markets concomitantly. The endemic banana quality problems reported by customers in the EEC and other markets around the world are scarring, bruising, knife injuries, crown rots, sooty mould, finger rots, speckling, under-peel discoloration, etc. These defects are complete turn-offs to the end users and have a significant negative...
