Última Effects of Agricultural Commercialization on Food Crop Input Use and Productivity in Kenya AgEcon Strasberg, Paul J.; Jayne, Thomas S.; Yamano, Takashi; Nyoro, James K.; Karanja, Daniel David; Strauss, John. The objective of this report is to analyze the effects of smallholder commercialization on food crop input use and productivity in rural Kenya. The main research issues were: (1) To examine the determinants of smallholder fertilizer use on food crops, with a focus on the effects of household and regional agricultural commercialization; (2) To examine the determinants of food crop productivity, again with a focus on the effects of commercialization; and (3) To discuss the implications of the findings for policy and additional research necessary to improve the contribution of cash cropping to rural food productivity growth and food security. A main premise of the paper is that the effects of commercialization are not uniform and cannot be generalized. The...

Ano: 1999 URL: http://purl.umn.edu/54675 THE WELFARE EFFECTS OF MAIZE TECHNOLOGIES IN MARGINAL AND HIGH-POTENTIAL REGIONS OF KENYA AgEcon Karanja, Daniel David; Renkow, Mitch; Crawford, Eric W.. This study uses a multi-market model of maize production to assesses the potential impact of "on-the-shelf" improved maize technologies on the welfare of rural and urban households in Kenya. We find that diffusion of technologies in favored areas is likely to have substantially greater positive impacts on aggregate real incomes.

Ano: 2002 URL: http://purl.umn.edu/19883 An Economic and Institutional Analysis of Maize Research in Kenya AgEcon Karanja, Daniel David. Maize, the most important food crop in Kenya, contributes 44 percent of the per-capita, calorie intake. Increases in maize production over the past three decades have been attributed to the availability and adoption of modern maize techniques, especially fertilizer and hybrid seed. This paper estimates the rate of return to maize research to be 53 to 61 percent, and reveals that his impact was aided by complementary agricultural extension and seed multiplication and distribution programs. The paper describes the institutional framework that may have led to one of Kenya’s agricultural research success stories. It also poses challenges to the future of maize production in Kenya.

Ano: 1999 URL: http://purl.umn.edu/11463 RURAL INFRASTRUCTURE, TRANSACTIONS COSTS, AND MARKETED SURPLUS IN KENYA AgEcon Renkow, Mitch; Hallstrom, Daniel G.; Karanja, Daniel David. We develop a conceptual framework for quantifying fixed transactions costs facing semisubsistence households. Using household survey data from a sample of 324 Kenyan maize farmers, we generate estimates of household supply and demand schedules, as well as the price bands that they face. Our econometric results indicate that on average the ad valorem tax equivalent of the fixed transactions costs facing the households in our sample is 28%. Additional analysis indicates that both remoteness and infrastructure quality have significant impacts on the size of the transactions costs facing farm households. To the best of our knowledge, ours are the first empirical estimates of the magnitude of transactions costs. Tipo: Conference Paper or Presentation Palavras-chave: Marketing.
