MARKET IMPERFECTIONS AND LAND PRODUCTIVITY IN THE ETHIOPIAN HIGHLANDS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Holden,   Stein T.; Shiferaw,   Bekele A.; Pender,   John L.
This study analyzes how market imperfections affect land productivity in a degraded low-potential cereal- livestock economy in the Ethiopian highlands. A wide array of variables is used to control for land quality in the analysis. Results of three different selection models were compared with least squares models using the HC3 heteroskedasticity-consistent covariance matrix estimator. Market imperfections in labor and land markets were found to affect land productivity. Land productivity was positively correlated with household male and female labor force per unit of land. Female-headed households achieved much lower land productivity than male- headed households. Old age of household heads was also correlated with lower land productivity. Imperfections in...

Leveraging institutions for collective action to improve markets for smallholder producers in less-favored areas
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shiferaw,   Bekele A.; Obare,   Gideon A.; Geoffrey,   Muricho; Silim,   Said.
Using survey data from the community, producer marketing groups (PMGs) and farm households in Kenya, this paper investigates the potential of rural institutions (farmer organizations, their rules and enforcement mechanisms) for remedying pervasive market imperfections and facilitate access to new technology in rural areas. Qualitative and quantitative analyses show that while the functioning of markets is constrained by high transaction costs and coordination failures, PMGs present new opportunities for small producers through vertical and horizontal coordination of production and grain marketing. They pay 20 to 25% higher prices than other buyers and facilitate the adoption of improved varieties that help increase marketable surplus. Their accumulated...

Policy Analysis for Sustainable Land Management and Food Security in Ethiopia: A Bioeconomic Model with Market Imperfections Food Security in Ethiopia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Holden,   Stein T.; Shiferaw,   Bekele A.; Pender,   John L.
Soil fertility and the lack of fertilizer use in Africa are frequently discussed topics. The problems of land degradation and low agricultural productivity, which result in food insecurity and poverty, are particularly severe in the rural highlands of Ethiopia. In many areas, a downward spiral of land degradation and poverty appears to be occurring. Finding solutions to these problems requires identifying effective entry points for farmers, governments, and civil society organizations, and understanding the potential impacts and tradeoffs that are likely to arise from alternative interventions. This report seeks to improve that understanding, using a bioeconomic model of land management and agricultural production developed for a community that is fairly...

Collective Action for Integrated Community Watershed Management in Semi-Arid India: Analysis of Multiple Livelihood Impacts and the Drivers of Change
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shiferaw,   Bekele A.; Bantilan,   Ma Cynthia S.; Wani,   Suhas; Sreedevi,   T.K.; Rao,   G.D. Nageswara.
Spatial and temporal attributes of watersheds and associated market failures require institutional arrangements for coordinating use and management of natural resources. Effective collective action (CA) for watershed management has the potential to provide multiple economic and environmental benefits - tangible and non-tangible - to rural communities. This allows smallholder farmers to jointly invest in management practices that provide collective benefits to community members. The functions of the group can also extend to include provision of new services like collective marketing of products and essential inputs. While watershed management contributes to resource productivity and sustainability, increased commercialization and market access open...

Poverty, Resource Scarcity and Incentives for Soil and Water Conservation: Analysis of Interactions with a Bio-economic Model
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shiferaw,   Bekele A.
The paper examines the interlinkages between population pressure and poverty, possible impacts on household welfare and land management, and the consequent pathways of development in a low potential rural economy. A dynamic non-separable bio-economic model, calibrated using data from the Ethiopian highlands, is used to trace key relationships between population pressure, poverty and soil fertility management in smallholder agriculture characterized by high levels of soil degradation. Farm households maximize their discounted utility over the planning horizon. Land, labor and credit markets are imperfect. Hence, production, consumption and investment decisions are jointly determined in each period. The level of soil degradation is endogenous and has...

Determinants of Agricultural Technology adoption: the case of improved groundnut varieties in Malawi
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Simtowe,   Franklin; Asfaw,   Solomon; Diagne,   Aliou; Shiferaw,   Bekele A.
This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the...

Agricultural Technology Adoption and Rural Poverty: Application of an Endogenous Switching Regression for Selected East African Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Asfaw,   Solomon; Shiferaw,   Bekele A.
Achieving agricultural growth and development and thereby improving rural household welfare will require increased efforts to provide yield enhancing and natural resources conserving technologies. Agricultural research and technological improvements are therefore crucial to increase agricultural productivity and thereby reduce poverty. However evaluation of the impact of these technologies on rural household welfare have been very limited by lack of appropriate methods and most of previous research has therefore failed to move beyond estimating economic surplus and return to research investment. This paper evaluates the potential impact of adoption of modern agricultural technologies on rural household welfare measured by crop income and consumption...

Rural institutions and producer organizations in imperfect markets: experiences from producer marketing groups in semi-arid eastern Kenya
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shiferaw,   Bekele A.; Obare,   Gideon A.; Muricho,   Geoffrey.
Many countries in sub-Saharan Africa have liberalized markets to improve efficiency and enhance market linkages for smallholder farmers. The expected positive response by the private sector in areas with limited market infrastructure has however been disappointing. The functioning of markets is constrained by high transaction costs and coordination problems along the production-to-consumption value chain. New kinds of institutional arrangements are needed to reduce these costs and fill the vacuum left when governments withdrew from markets in the era of structural adjustments. One of these institutional innovations has been the strengthening of producer organizations and formation of collective marketing groups as instruments to remedy pervasive market...

Community Watershed Management in Semi-Arid India: The State of Collective Action and its Effects on Natural Resources and Rural Livelihood
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shiferaw,   Bekele A.; Kebede,   Tewodros A.; Reddy,   V. Ratna.
Spatial and temporal attributes of watersheds and the associated market failures that accelerate degradation of agricultural and environmental resources require innovative institutional arrangements for coordinating use and management of resources. Effective collective action (CA) allows smallholder farmers to jointly invest in management practices that provide collective benefits in terms of economic and sustainability gains. The Government of India takes integrated watershed management (IWM) as a key strategy for improving productivity and livelihoods in the rain-fed and drought-prone regions. This study investigates the institutional and policy issues that limit effective participation of people in community watershed programs and identifies key...
