Última A Unified Approach to the Estimation of Demand for Improved Seed in Developing Agriculture AgEcon Langyintuo, Augustine S.; Hamazakaza, Petan; Nawale, Edah; Mekuria, Mulugetta. This paper proposes a new approach for estimating the demand for seed within a developing country context where only improved seeds are sold but adoption rates for improved varieties low. A farmer views an improved seed firstly as a derived input embodying production attributes and secondly, as a technology embodying consumption characteristics. He therefore jointly decides on its adoption and the quantity of seed required to plant a predetermined area. Drawing on the theory of demand for consumption goods characteristics and production input attributes, this paper specified and estimated non-separable household demand and consumption models using data collected from 300 farm households in Zambia during the 2003/04 crop season. The estimated results...

Ano: 2006 URL: http://purl.umn.edu/25332 Agricultural Household Response to Avian Influenza Prevention and Control Policies AgEcon Beach, Robert H.; Poulos, Christine; Pattanayak, Subhrendu K.. Recent outbreaks of highly pathogenic avian influenza in Asia, Europe, and Africa have caused severe impacts on the poultry sector through bird mortality and culling, as well as resulting trade restrictions and negative demand shocks. Although poultry producers play a major role in preventing and controlling avian influenza, little research has examined the influence of their farm-level decision making on the spread of the disease. In this study, we describe farm behavior under livestock disease risk and discuss data and analyses necessary to generate sound empirical evidence to inform public avian influenza prevention and control measures.

Seasonal wage labour was rarely distinguished from the permanent one in farm-household models although it has sharply increased in developed countries. Therefore, we propose to endogenize the demand for this peculiar labour type and highlight the trade-offs for the various labour combinations on farms. We use data on fruit and vegetables farms drawn from the 2000 French agricultural census. We show that seasonal wage labour is a substitute for permanent wage employment, and doesn't entirely follow the seasonality of the agricultural activity: competition on the labour and product markets play a significant role in the employment of labour types.

Plant invasions and their impact on land use pose difficult research questions, due to the complex relationships between the ecological nature of the invasion and the human responses to the invasion. This paper focuses on the linkages between an invasion of bracken fern and land use decisions in an agricultural frontier in southern Mexico. Agriculture in this region is practiced on an extensive basis, using traditional slash-and-burn techniques of temporary cultivation and continuous rotation through forest fallow. We investigate the factors that affect the decision of a subsistence farmer to either continue cultivating an invaded agricultural plot or permanently abandon the plot and cultivate elsewhere. We develop an agricultural household model of land... Tipo: Journal Article Palavras-chave: Bracken fern invasion; Land abandonment; Agricultural household model; Mexico; Land Economics/Use. Ano: 2006 URL: http://purl.umn.edu/10184 OFF-FARM WORK PARTICIPATION, OFF-FARM LABOR SUPPLY AND ON-FARM LABOR DEMAND OF U.S. FARM OPERATORS AgEcon Huffman, Wallace E.; El-Osta, Hisham S.. An agricultural household model provides the framework for modeling off-farm work participation and off-farm and on-farm work decisions of farm operators. The empirical results are obtained from fitting the econometric model to data from a large national survey. In the estimated structural off-farm work participation equation, the operator's off-farm wage offer has a strong positive effect and other household income has a negative effect on the probability of off-farm work. For farm operators who participate in off-farm work, the wage elasticity of their off-farm labor supply is positive but of their on-farm labor demand is zero. The income elasticity of off-farm work for those who participate in off-farm work and of on-farm work for those who...

Ano: 1997 URL: http://purl.umn.edu/18280 Relative Growth of Subsidiary Farming in Post-Soviet Economies: A Labor Supply Story AgEcon Kurkalova, Lyubov A.; Jensen, Helen H.. An agricultural household model (AHM) is applied to analyze the changes in labor supply of post-Soviet households. Extensions of the model are presented in which wage and pension arrears are modeled as income uncertainty. Considering two models, one for wage earning households and another for pensioners, we find that wage and pension uncertainties increase subsidiary farming hours and so does a mean-preserving spread in the distribution of pensions. A decline in the probability of receiving wages not only increases subsidiary farming hours but also reduces wage work hours.

Ano: 2000 URL: http://purl.umn.edu/18461 Technology Adoption and Off-Farm Household Income: The Case of Herbicide-Tolerant Soybeans AgEcon Fernandez-Cornejo, Jorge; Hendricks, Chad; Mishra, Ashok K.. We model the interaction of off-farm work and adoption of agricultural technologies and the impact of adopting these technologies on farm household income from on farm and off-farm sources after controlling for such interaction, and estimate the model for the case of adoption of herbicide-tolerant (HT) soybeans using a nationwide survey of soybean farms for 2000. We find that adoption of HT soybeans is positively and significantly related to off-farm household income for U.S. soybean farmers, after controlling for other factors. In addition, while on-farm household income is not significantly related to adoption, total household income increases significantly with adoption.

Ano: 2005 URL: http://purl.umn.edu/43487 THE DETERMINANTS OF TIME SPENT ON SOCIAL, COMMUNITY AND LEISURE ACTIVITIES BY FARM HOUSEHOLDS IN THE WEST OF IRELAND AgEcon Keogh, Sinead; Cullinan, John. Understanding the determinants of farm households’ social engagement patterns in rural communities is important for public policy programs that seek to improve the well-being of the rural population and promote rural sustainability. Within this context, this paper examines the factors that influence both the participation in, and the number of hours dedicated to, social, community and leisure activities among farm operators and their spouse/partner in a region in the West of Ireland. The theoretical underpinnings of this research are an extension of Becker’s (1965, 1974) and Gronau’s (1977) agricultural household models, whereby households maximise utility subject to a set of constraints, household income and time endowment. The study employs a time-use...

Ugandan smallholder farmers produce the nation's major food crop using numerous banana varieties with distinctive attributes, while coping with important biotic constraints and imperfect markets. This empirical context motivates a trait-based model of the agricultural household that establishes the economic association between household preferences for specific variety attributes (yield, disease and pest resistance, and taste), among other exogenous factors, and variety demand, or the extent of cultivation. Six variety demands are estimated in reduced form, each in terms of both plant counts ("absolute" or levels demand) and plant shares ("relative" demand). Two salient findings emerge from the analysis: 1) the determinants of both absolute and relative...
