An Error Corrected Almost Ideal Demand System for Major Cereals in Kenya AgEcon
Nzuma, Jonathan M.; Sarker, Rakhal.
Despite significant progress in theory and empirical methods, the analysis of food consumption patterns in developing countries, particularly those in Sub Saharan Africa has received very limited attention. An attempt is made in this article to estimate an Error Corrected Almost Ideal Demand System for four major cereals consumed in Kenya employing annual data from 1963 to 2005. The model performs well both on theoretical and empirical grounds. All own-price elasticities are negative and statistically significant and all cereals are necessities both in the short-run and in the long-run in Kenya.

ASSESSING THE EFFECTS OF NAFTA ON CANADA/US AGRICULTURAL TRADE AgEcon
Deng, Hugh; Nzuma, Jonathan M..
While there seems to be an agreement that Canada-US Free Trade Agreement (CUSTA)/North American Free Trade Agreement (NAFTA) have benefited member countries, some analysts have argued that the agreements had little effect on the bilateral Canada/US agricultural trade as many other factors have contributed to the increased trade flows. Results from this study reveal that the aggregate bilateral agricultural trade flows have generally experienced a steady growth since the implementation of NAFTA with trade flows seemingly favoring Canada more than the US since 1992. At the industry level, the impacts of NAFTA on Canada/US agricultural trade were varied with the sub-sectors analyzed responding differently to the bilateral trade liberalization.

Testing for Oligopoly Power in the Kenyan Seed Maize Processing Industry AgEcon
Nzuma, Jonathan M..
In the recent past, the concentration of seed maize processing and marketing in Kenya has raised serious public concerns. The inability of this industry to ensure affordable prices of certified seed maize for the farming community has led policy makers to question its market behaviour. In spite of these concerns, the performance of agricultural markets in Kenya has received little attention. This study evaluates the market conduct of the industry using the New Empirical Institutional Organization framework and tests the hypothesis of price taking behaviour. A system of five equations was used to estimate conjectural variations elasticity while a Lerner index was constructed to measure market power using data from Kenya's Central Bureau of Statistics. The...

The impact of non-tariff barriers on maize and beef trade in East Africa AgEcon
Karugia, Joseph Thuo; Wanjiku, Julliet; Gbegbelegbe, Sika; Nzuma, Jonathan M.; Massawe, Stella; Macharia, Eric; Freeman, H. Ade; Waithaka, Michael M.; Kaitibie, Simeon; Gulan, Ayele.
The East African Customs Union was established in 2005 with the aim of increasing intraregional trade. The Customs Union protocol commits member states to eliminate non-tariff barriers (NTBs) to intraregional trade. However, several NTBs are still applied by member states. This study identifies the existing NTBs on maize and beef trade and quantifies their impact on trade and welfare of EAC citizens using a Spatial Equilibrium Model (SEM). Data on NTBs were collected from traders and transporters of maize and beef cattle in East Africa. Roadblock checks, bribes and custom rules and procedures were identified as the main NTBs to trade. The SEM model shows that a 50% reduction of the cost of NTBs, or their complete elimination would improve social welfare in...

Who are the Real Gainers of Trade Liberalization in Kenya's Maize Sector? AgEcon
Nzuma, Jonathan M.; Sarker, Rakhal.
In Kenya, trade policy reforms in the cereals sector were initiated as a key component of the economy-wide structural adjustment programmes (SAPs) during the mid 1980s. The SAPs were later strengthened and made irreversible by Kenya’s commitments at the multilateral trade negotiations. However, the welfare effects of these trade policy reforms remain controversial. This paper to quantifies the market and welfare impacts of trade liberalization in Kenya’s maize sector using a partial equilibrium model with market interrelationships at the farm, wholesale and retail levels. The model is calibrated to simulate a 24 percent reduction in maize import tariffs and a complete abolition of tariffs. The simulations results suggest that tariff reductions yield price...
