A mixed-method approach for determining the risk and complexity farmers associate with using forward contracts AgEcon
Jackson, Elizabeth; Quaddus, Mohammed; Islam, Nazrul; Stanton, John.
This paper reports on a model that was developed to understand the behavioural determinants surrounding farmers’ adoption of forward contracts for agricultural commodities. Based on the Theory of Planned Behaviour and Diffusion of Innovations, 28 hypotheses within the model were written and then tested via a telephone survey that gathered 305 responses from Western Australian wool producers. The data from the telephone survey were analysed using SPSS 14 and the Partial Least Squares approach to Structural Equation Modelling. Most relationships within the model could be explained after rigorous quantitative analysis, however, further explanation was required to understand two final aspects of adoption behaviour: firstly, the sources of risk wool...

BIOLOGICAL MANUFACTURING AND INDUSTRIALIZATION OF PRODUCTION AGRICULTURE AgEcon
Boehlje, Michael; Gray, Allan W..
Farming is in the midst of a major transformation—not only in technology and production practices, but also in size of business, resource control and operation, business model and linkages with buyers and suppliers. Both the livestock and grain sectors are changing from an industry dominated by family-based, small and modest size, relatively independent firms to one of generally larger businesses following an industrial business model that are more tightly aligned across the value chain. We describe some of the fundamental concepts and characteristics of biological manufacturing and then illustrate these characteristics with a brief description of three modern farming businesses. The characteristics include: attribute driven or differentiated products, a...

Did the CAP reform affect off-farm labour participation in Italian farms? AgEcon
Corsi, Alessandro; Salvioni, Cristina.
The process of change in the Common Agricultural Policy (CAP) from trade and market distorting measures to more neutral interventions has been long, but in this process the 2003 reform (the so-called Fischler reform) has been the most important step, leading to a more decoupled, and hence less market distorting, support (Oecd, 2004) and introducing the fully decoupled Single Farm Payment Scheme (SFP). In this paper, we estimate a model of operators’ off-farm labour participation from a panel of Italian COP farms drawn from the FADN. To this purpose we use a random effects probit model, thus controlling for unobserved heterogeneity. The results suggest that the effects of the reform on off-farm labour participation, if any, are weak. No variable directly...

Evaluation of Internalisation Processes in Environmental Management Systems: Aquaculture and Offshore Mussel Farming AgEcon
Malorgio, Giulio.
In recent years, particular attention has been paid to fishing activities, and more specifically to aquaculture, a production process whose environmental impact at present is not being adequately submitted to any sort of serious assessment and control. The impact of aquaculture on the environment has nonetheless become an important issue for both potential customers and public opinion. The purpose of this study is to appraise environmental protection costs if and when a certified program of environmental management is put into effect in an attempt to change the present situation in which firms only comply with minimum environmental standards. A survey was conducted of all relevant information regarding production, organization, and budgetary aspects at...

Factors Affecting Beef Cow-Herd Costs, Production, and Profits AgEcon
Ramsey, Ruslyn; Doye, Damona G.; Ward, Clement E.; McGrann, James M.; Falconer, Lawrence L.; Bevers, Stanley J..
Cow-herd standardized performance analysis (SPA) data for Texas, Oklahoma, and New Mexico were used to determine economic factors affecting cow-herd costs, production, and profitability. Total cost was defined as the financial cost associated with raising a calf through the weaning stage; production, as pounds weaned per exposed female; and profits, as a rate of return on assets. Variable affecting one of more performance measures included herd size; pounds of feed fed; real estate, machinery, and breeding-stock investments; calving percentage; death loss; and breeding-season length. Management variables were especially important for financial costs and profitability of the cow-herd operation.

Forward Pricing Behavior of Corn and Soybean Producers AgEcon
Davis, Todd D.; Patrick, George F.; Coble, Keith H.; Knight, Thomas O.; Baquet, Alan E..
Forward pricing behavior of random samples of Indiana, Nebraska, and Mississippi crop producers was analyzed using Heckman’s two-step limited information maximum likelihood estimation procedure. Producers who forward priced during the 1995-1998 period generally expected to forward price in 1999 using similar techniques. Probit models were estimated for cash forward contracts and taking a direct position in futures or options separately and combined. Results provide limited support for the hypothesis that forward pricing should be analyzed as an adoption decision. Variables reflecting risk attitudes do affect the decision to use forward pricing, while variables to economic position affect the level of forward pricing.

Information Based Estimators for the Non-Stationary Transition Probability Matrix: An Application to the Danish Pork Industry AgEcon
Karantininis, Kostas.
A generalised cross entropy instrumental variables estimator is used to recover the non-stationary transition probability matrix for the Danish pork industry. A technique is also developed to recover missing data points due to category re-specifications. The impact of a set of exogenous variables (prices of pork meat, inputs, and pork substitutes), are evaluated in the form of elasticities. An overall assessment of entry exit and growth of farms is performed.

Michigan Production Costs for Tart Cherries by Production Region AgEcon
Black, J. Roy; Nugent, James; Rothwell, Nikki; Thornsbury, Suzanne; Olynk, Nicole J..
The weighted average cost of producing tart cherries in Michigan on a representative farm in 2009 is $0.36/lb. This cost was averaged across the three main production regions in Michigan and weighted by average per acre production for each region as published by the Michigan Agricultural Statistics Service. --Costs vary across the main production regions and by farm size. Costs are about $0.04/lb less for mid-sized farms in Northwest Michigan and $0.08/lb and $0.10/lb in West Central and Southwest Michigan, respectively. --This report was developed through interviews with tart cherry growers and other experts in each of the three main growing regions in 2005 and 2006. Many of the numbers were updated in 2009. --The cost of production calculation is based...

Production Performance and Economic Appraisal of Broiler Farms in Anand District of Gujarat AgEcon
Shaikh, A.S.; Zala, Y.C..
The production performance of different sizes of broiler farms has been studied by collecting data from 60 broiler producers of Anand district during 2005. To examine production performance, the average feed conversion ratio, livability percentage, average body weight and age at marketing have been worked out. Though broiler production is capital-intensive, it has been found profitable. The average cost of production per broiler has been found to be ` 64 and per kilogram live weight of broiler as ` 32. The variable cost and fixed cost constitute 84.5 per cent and 15.5 per cent of total cost, respectively. The major cost components have been found as feed cost (58.6%), chick cost (21.5%) and depreciation on buildings (10.7%). The net profit per broiler as...

Technical Efficiency among Organic and Conventional Farms in Sweden 2000-2002: A Counterfactual and Self-Selection Analysis AgEcon
Larsen, Karin; Foster, Kenneth A..
Technical efficiency and its determinants among organic and conventional farms in Sweden are analyzed for time-period 2000-2002. In addition, we address the issues that arise when comparing performance measures among the two groups of producers (conventional and organic) due differences in their technologies and the potential presence of self-selection in the farmer's choice of using conventional or organic production methods. If the choice of production method is based on, or at least in part based on, the farms expected productivity in organic and conventional farming respectively there is self-selection present that must be considered. We apply an endogenous switching regression model suggested by Lee (1978) to compare efficiency measures between the...

The effect of environmental cross compliance regulations on Swiss farm productivity AgEcon
Bokusheva, Raushan; Kumbhakar, Subal C.; Lehmann, Bernard.
This paper analyzes the evolution of Swiss farm productivity during the implementation of environmental policy reforms. We employ a production model formulation with technology parameters defined as the functions of subsidies, as well as individual farm characteristics. Our estimates for two groups of farms – milk-producing and crop farms – show that introducing environmental regulations induced serious changes in the production technology and productivity of inputs, especially of land, labor and fertilizer. The overall effect of the subsidies on the production output has been found negative. At the same time, we find that farms do not use their resources optimally, which indicates some deficiencies in structural adjustments, primarily in the land and...

The Efficiency of Labor Input in the Tree Nut Growers Industry: A Stochastic Frontier Production Approach Study in Butte County, California AgEcon
Chang, Kuo-Liang; Lone, Todd A..
The U.S. government recruits immigrant workers through the H-2A program as a short-term solution to the agricultural sectors’ labor shortage problem. Although the sector insists hiring immigrant workers is essential for their survival, history has proven the socio-economic cost for doing so is enormous. This paper aims to investigate the contribution of labor to agricultural production efficiency. A discussion of marginal rate of technical substitution, economies of scale, and economies of scope will also be included. The stochastic production frontier regression approach was applied to input/output data collected from a survey of tree nut growers in Butte County, California. Results indicate the labor input is not significant in deciding farm production...

The Role of Agriculture in Reducing Poverty in Tanzania: A Household Perspective from Rural Kilimanjaro and Ruvuma AgEcon
Sarris, Alexander H.; Savastano, Sara; Christiaensen, Luc J.M..
This paper explores how farm productivity affects poverty, and how various factor market constraints affect farm productivity. The empirical analysis draws on representative surveys of farm households in Kilimanjaro and Ruvuma, two cash crop growing regions in Tanzania. We find that poorer households do not only possess fewer assets, but are also much less productive. We find that agricultural productivity directly affects household consumption and hence overall poverty and welfare. Stochastic production frontier analysis indicates that many farmers are farming well below best practice in the region. Analysis of allocative efficiency suggests that family labour is substantially over utilized, a sign of considerable excess labour supply. Use of intermediate...

Where has all the cream gone: How sustainable is the English dairy supply chain? AgEcon
Glover, Jane.
The sustainability of the dairy supply chain is a widely debated topic in the industry. The purpose of this paper is to explore farmer behaviour in response to diminishing returns and investigates the possible long-term implications of low returns, identified by farming families. The paper argues that, sustained declines in margins, coupled with other structural changes in the industry, will eventually lead to an exodus of small family farms. A qualitative methodology ensures in-depth data were collected over a five year period. The results indicate that farmers and their families are concerned over the reduced margins for their produce, with many smaller farms forced to subsidies the business with alternative sources of income. Farmers also raise concerns...
