Última An Evaluation of Tennessee Soybean Growers’ Views on a New Generation Cooperative to Produce Biodiesel 31 Jensen, Kimberly L.; English, Burton C.; Menard, R. Jamey; Zhang, Yu. Substituting petroleum diesel with biodiesel could decrease air emissions, reduce reliance on foreign oil, and help expand markets for U.S. farmers. Soybean producers can potentially capture this value-added by forward integrating the processing of soybeans into biodiesel via a New Generation Cooperative (NGC). Using probit analysis, this study examines factors influencing soybean producers’ willingness to participate in an NGC to produce biodiesel. Tobit analysis is used to examine the factors influencing the number of shares the soybean producer would be willing to purchase. Survey results indicate that over 70% of the soybean producers in the study group are interested in investing in an NGC to produce biodiesel. Among those producers willing to...

In this paper the conceptual framework of individual farmers' adoption decisions of new agricultural technologies is used to identify factors that influence adoption modified fanya juu terraces in semi-arid eastern Kenya. The adoption decision model was specified using farm and farmers' characteristics and technology characteristics though likely to influence farmers' adoption behaviour. To test intensity of adoption a Torbit model was specified and estimated. Results of logit regression analysis reveal that access to markets, education, costs, technology attributes, labour, credit and risk preferences significantly influenced adoption decisions. Results from the estimated intensity of adoption model (tobit) show that variation in the proportion of land...

Ano: 2004 URL: http://purl.umn.edu/58369 The association of agricultural information services and technical efficiency among maize producers in Kakamega, western Kenya 31 Nambiro, Elizabeth; Chianu, Jonas; Murage, Alice W.. Maize is the staple food for most Kenyan households, and grown in almost all the farming systems. Due to diminishing farm sizes in Kakamega District, crop productivity and the efficiency of farming systems are of great concern. This paper aims to provide empirical evidence on the links between efficiency in maize production and access to soil-related agricultural information services. Using cluster sampling, a total of 154 farmers in Kakamega District were interviewed. A 2–step estimation technique (Data Envelopment Analysis (DEA) and Tobit model) were used to evaluate the technical efficiencies among the farmers and the factors explaining the estimated efficiency scores. Data was disaggregated into farmers with and those without access to soil-related...

Ano: 2010 URL: http://purl.umn.edu/95961 VISITOR PREFERENCES AND VALUES FOR WATER-BASED RECREATION: A CASE STUDY OF THE OCALA NATIONAL FOREST 31 Shrestha, Ram K.; Alavalapati, Janaki R.R.; Stein, Taylor V.; Carter, Douglas R.; Denny, Christine B.. We used the open-ended contingent valuation method to elicit willingnes to pay (WTP) for day visitors and extended visitors on the Ocala National Forest (ONF), Florida. A Tobit model specification was applied to account for the issues involved with censored WTP bids. The results reveal that visitors would pay more for improved recreational facilities at the ONF. In particular, our estimates show that visitors would pay $1 million for basic facilities, $1.9 million for moderate improvements, and $2.5 million for more improvements.

Ano: 2002 URL: http://purl.umn.edu/15069 Who Has Time To Cook? How Family Resources Influence Food Preparation 31 Mancino, Lisa; Newman, Constance. Households participating in the Food Stamp Program are increasingly headed by a single parent or two working parents. As this trend continues, more low-income households may find it difficult to allocate the time needed to prepare meals that fit within a limited budget and meet dietary requirements. Using Tobit analysis of the 2003-04 American Time Use Survey (ATUS), this study finds that household time resources significantly affect how much time is allocated to preparing food. In fact, working full-time and being a single parent appear to have a larger impact on time allocated to food preparation than an individual’s earnings or household income do. The results are relevant for the design of food assistance programs as well as for improving our...
