The Role of Unobserved Farm Efficiency AgEcon Dolev, Yuval; Kimhi, Ayal. We analyze the growth of family farms in Israeli cooperative villages between 1981 and 1995, using longitudinal data. We use instrumental variables to account for the endogeneity of initial farm size, and correct for selectivity due to farm survival. We also include a technical efficiency index, derived from the estimation of a stochastic frontier production model, as an explanatory variable. We find that technical efficiency is an important determinant of farm growth, and that not controlling for technical efficiency could seriously bias the results. The size distribution of Israeli family farms is found to be mostly diverging, while without technical efficiency farm growth seemed to be predominantly random.

Ano: 2008 URL: http://purl.umn.edu/45778 Effects of Traceability on the Italian Fresh Vegetables Market: A Demand System Simulation AgEcon Caracciolo, Francesco; Cembalo, Luigi. Traceability can serve various purposes in the food sector, including that of chain quality control. However, the aspects that seem to be most frequently required of traceability are those related to food safety. Nevertheless, traceability systems development has recently shifted its focus from the major aspects of food safety to a price premium search approach. Although such an approach often appears to lie behind production strategies, there is no technical or theoretical evidence to support it: traceability systems do not guarantee, per se, quality. On the other hand, a rigorous traceability system that pursues multiple objectives involves costly procedures that are very likely to feed all the way up to the consumer side. The mainstream literature is...

Ano: 2010 URL: http://purl.umn.edu/100503 ECONOMIC INCENTIVES FOR DIETARY IMPROVEMENT AMONG FOOD STAMP RECIPIENTS AgEcon Lin, Biing-Hwan; Yen, Steven T.; Dong, Diansheng; Smallwood, David M.. Most Americans need to consume more fruits, vegetables, and dairy products. This need is particularly acute among low-income individuals. The objective of this study is to examine the cost effectiveness of two economic policies that use alternative policy levers available within the Supplemental Nutrition Assistance Program (formerly Food Stamp Program) to increase consumption of these under-consumed foods. Data from three nationally representative surveys are used to estimate demand elasticities, marginal propensity to spend on food out of food stamp benefits, and consumption amount of and spending on under-consumed foods among food stamp recipients. Results of the analyses suggest that a 10% price subsidy would curtail consumption deficiencies by 4–7% at...

Ano: 2009 URL: http://purl.umn.edu/53339 The supermarket revolution and impacts on agricultural labor markets: Empirical evidence from Kenya AgEcon Rao, Elizaphan J.O.; Qaim, Matin. Many developing countries are currently experiencing a rapid expansion of supermarkets. New supermarket procurement systems could have important implications for farming and wider rural development. While previous studies have analyzed farm profit and income effects, possible employment effects have received much less attention. Building on data from a recent survey of vegetable farmers in Kenya, in this article a double-hurdle model of hired labor use is developed and estimated. Farmer participation in supermarket channels increases the likelihood of hiring labor by 13% and overall demand for hired labor by 38%. A gender disaggregation shows that positive employment effects are especially pronounced for female hired labor. Given that agricultural wage...
