Smallholders' Cost Efficiency in Mozambique: Implications for Improved Maize Seed Adoption AgEcon
Zavale, Helder; Mabaya, Edward T.; Christy, Ralph D..
Maize is an important staple in Mozambique. It is also a dominant crop produced by smallholder farmers. However, the actual maize yields, currently estimated at 1.4 tons/ha, fall short of potential yields of 5-6.5 tons/ha. With population growth rate increasingly exceeding agricultural (and maize) productivity growth rate, the government of Mozambique faces a serious problem of food insecurity and poverty alleviation. This study examines cost inefficiency among smallholder maize farmers in Mozambique, and the impact of improved maize seed adoption on cost efficiency. A Translog functional form is used to estimate the frontier cost function. A cost-inefficiency function is used to examine the factors that determine cost inefficiency among farmers....

Integration and Equilibrium in the Maize Markets in Southern Africa AgEcon
Mutambatsere, Emelly; Mabaya, Edward T.; Christy, Ralph D..
For most countries in southern Africa, food security has been addressed through self-sufficiency, traditionally attained through widespread government involvement in the input and output markets for major food commodities. Food policies through the 1980’s have been characterized by input subsidies for farmers; fixed, pan-seasonal and pan-territorial farm level pricing systems, mainly implemented through parastatal marketing boards; as well as subsidies and price controls at the wholesale and retail levels. Under Structural Adjustment Programs of the 1990’s, most of those policies were abandoned for more market oriented policies. During the same period, many countries in the region joined the multilateral trading system, and on a regional level, two...

Consumer Preferences for Organic and Fair Trade Chocolate: Implications for Sustainable Agriculture in the Developing World AgEcon
Conner, David S.; Mabaya, Edward T..
This paper examines results of a consumer survey measuring consumer awareness and attitudes concerning two labels, certified organic and certified Fair Trade. These labels provide information about the social, economic and environmental sustainability of the production and marketing practices of goods imported from the developing world. Conjoint analysis is used to measure how consumers value organic and fair trade compared to other attributes like price. Results indicate favorable attitudes and value placed on these the sustainable attributes, and imply a role for these labels to provide incentives for the adoption of more sustainable practices.

Adoption of Improved Maize Seed by Smallholder Farmers in Mozambique AgEcon
Zavale, Helder; Mabaya, Edward T.; Christy, Ralph D..
The objective of this paper is to investigate factors influencing the adoption of improved maize seed by smallholder farmers in Mozambique. The data used in this study were obtained from a national random sample of 4,908 smallholder farmers conducted by the Ministry of Agriculture and Rural Development in 2002. Using Probit and Logit models, the main factors influencing adoption of improved maize seed were identified. The results of this analysis indicate that fifteen out of twenty five factors are significantly found to be the determining factors influencing the probability of adopting improved maize seed. To increase the likelihood of adopting improved maize seed, policy makers should put more emphasis on improving rural infrastructures and providing...

The Current State of Agribusiness Education and Training in Africa AgEcon
Mabaya, Edward T.; Christy, Ralph D.; Bandama, Maureen.
To spur rural development and food security, agricultural education and training in Africa has traditionally focused on increasing agricultural productivity on the farm. More recently, development practitioners and policy makers have broadened their attention to include agribusiness or agro-industries. However, the role of Agricultural Education and Training in fostering agribusiness growth in developing countries is relatively underexplored. This paper analyses the current state of agribusiness education and training in Sub-Saharan Africa. The paper is organised around five objectives. First, the paper characterises the macroeconomic environment—political, economic, social and technological—in which agribusiness development is taking place in Africa....

Spatial Price Adjustment with and without Trade AgEcon
Stephens, Emma C.; Mabaya, Edward T..
In this paper we introduce a switching error correction model (SECM) estimator that allows for the possibility that price transmission between markets might vary during periods with and without physical trade flows. Applying this new approach to semi-weekly data on tomato markets in Zimbabwe, we find that intermarket price adjustment occurs quickly and as much when there is no trade as when product flows from one market to another. This finding underscores the importance of information flow for market performance.

Supplying Improved Seed to Farmers in Rural Kenya: The Case of Freshco Kenya Ltd. AgEcon
Mabaya, Edward T.; Cramer, Laura K.; Mahiga, Veronica K.; Pham, Huong Q.; Simpson, Tara M.; Tang, Xiaowei C..
Freshco, a small producer and distributor of hybrid maize seed and macadamia seedlings, was one of the first private companies to enter the Kenya seed market after its liberalization. Currently, the company produces and markets six high yielding maize varieties that are suited for diverse agro-ecological conditions. Despite the company’s encouraging growth in the local maize seed market, Freshco’s executives recognize the need to scale up operations to stay competitive. The company’s challenge is to recognize business opportunities and customer needs in an environment susceptible to ecological, political, and socioeconomic change.

Smallholders’ Cost Efficiency in Mozambique: Implications for Improved Maize Seed Adoption AgEcon
Zavale, Helder; Mabaya, Edward T.; Christy, Ralph D..
The objectives of this paper are to estimate cost efficiency and investigate factors influencing the cost efficiency of maize-growing smallholders in Mozambique. The data used in this study came from a national random sample of 4,908 smallholder farmers conducted by the Ministry of Agriculture and Rural Development in 2002. Stochastic cost frontier and self-selection bias methods are used. The results indicate that twelve out of twenty factors are significantly found to be the determining factors influencing the cost efficiency. To enhance the cost efficiency of producing maize, policy makers should put more emphasis on improving rural infrastructures, providing better education, and providing access to credit.
