| This study focuses on development of agricultural best management practices (BMPs) for potato production areas in Northeast Florida, and presents the results of the initial situation assessment. BMP implementation is the primary strategy used by agencies and farmers to improve the efficiency and to ensure environmental sustainability of agricultural production. Although BMPs are defined as “economically feasible” and “cost-effective”, economic analysis conducted as a part of BMP development has been limited, leaving the room for disagreement about economic impacts of specific BMPs. As a part of the situation assessment, we used interviews, group discussions, a survey, and a field trip to collect information about farmers’ production practices and to... |

| The culling of the sows is an important task of the breeders and farmers, besides it is a determining factor of profitable pork production. During our research we have surveyed the data of 1969 sows in a Hungarian large-scale pig farm. For the calculation of our results we used one of the non-parametric forms of survival analysis, the Kaplan-Meier analysis. For the quantification of death intensity we applied another survival analysis model, the log-rate exponential model. We have found out the risk values of various culling reasons form the point of view of culling. Besides, we tried to quantify by an economic model how the production period of sows influences the average costs of piglets and the average costs of piglets per kilo at 2006 prices. We... |

| Agriculture and aquaculture have common features associated with their biological nature affecting risk exposure of the businesses. The aim of this paper is to compare risk exposure in salmon farming and agricultural enterprises in Norway by using an implicit error component model to examine the risk structure of yields, prices and economic returns at the farm level. Results indicate a higher farm-level year-to-year variability in yields, prices and economic returns in salmon farming than in agricultural enterprises. The variability in livestock enterprises was generally lower than for crop enterprises. Return on assets was highest in salmon farming with an average annual return of 9.2%. All of the agricultural farm types exhibited a negative average... |

| In this paper we consider factors that affect both crop prices and yields in order to examine supply responses of major crops in the Southeast. Due to the variable nature of crop production in the Southeast, previous studies that ignore price and yield risk may fail to capture one of the salient features of the region’s agriculture. Our results indicate supply elasticity values for corn, cotton, and soybeans of approximately 0.670, 0.506, and 0.195, respectively. Compared with the results of studies in other regions, corn and cotton acres respond more to price changes and soybean acres respond less to price changes. |

| A method of stochastic dominance analysis with respect to a function (SDRF) is described and illustrated. The method, called stochastic efficiency with respect to a function (SERF), partitions a set of risky alternatives in terms of certainty equivalents for a specified range of attitudes to risk. It can be applied for any utility function with risk attitudes defined by corresponding ranges of absolute, relative or partial risk aversion coefficients. SERF involves comparing each alternative with all the other alternatives simultaneously, not pairwise as with conventional SDRF. Hence it yields a subset of the efficient set found by SDRF. Moreover, the method is readily implemented in a simple spreadsheet with no special software needed. |

| Drawing upon a comparative case study of organic and conventional farming in Western Greece, the aim of this study is threefold: firstly, to explore the organic and conventional farmers’ profile through a factor analysis. Secondly, to assess the economic viability of organic cultivation with respect to profitability and risk behaviour, through a Monte Carlo stochastic simulation model. Thirdly, to discuss the necessity for additional income insurance schemes. Research findings indicate that the organic cropping system currently stands out as the most economically viable alternative under the assumption of the existing payments; without payments, however, conventional agriculture would be preferred by all farmers, regardless of their degree of risk aversion |

| The called Rural Familiar Agroindustry aims at, over all, the production of value of exchange which takes place in the commercialization. From the presuppose that exists an important pass between the agricultural production and its draining, the article brings an analysis of the economic viability of the rural familiar agroindustry, bringing as case study a typical agroindustry of candies of fruits in the Zona da Mata Mineira region. By the elaboration of the box flow of the project, a sensibility analysis and a risk analysis by the Mont Carlo simulation method were realized. The joined results were favorable to the stimulation to the implantation in a bigger scale, with public policies, of projects as the studied one, as a proposal of regional development. |

| We assess the economic feasibility of a 10 MMGY biodiesel plant using a Monte Carlo Cash Flow model programmed in Excel using @Risk, a simulation and risk analysis software. The model incorporates stochastic components to capture uncertainty in the analysis. The stochastic components are mainly variables that may exhibit risk, such as input prices, output prices, and expected revenues, and these are assigned probability distributions in the model. The model is programmed with three output variables: stream of revenues, profits/loss, and the resulting net present value (NPV) over ten year forecast period. Results from the cash flow analysis show that average expected revenues from the sale of biodiesel and co-products will be $48.5 million and total... |

| After the introduction of the new tobacco regime, many regions in Greece, formerly specialized in tobacco cultivation, are now facing serious threats of economic and social decline. Sheep farming is considered by many analysts as a viable alternative to tobacco. This study analyses the financial performance of sheep production and the risk that producers are taking. Through a stochastic efficiency analysis with respect to a function we explore the economic viability of conventional and organic sheep farming; key factors determining the economic outcome of these activities are also investigated. Both organic and conventional sheep farming appear as viable alternatives. The viability of organic farming lies, mainly, in organic payments. Conventional farming... |

| In order to analyse risks and to choose from different decision-making strategies simulation models are often applied in several areas of animal breeding. We developed an improved Monte Carlo model for analysing laying hen breeding combined with Bayes statistics. On the basis of data from a company breeding broiler parents, our paper examines the technological and economic risks of breeding a laying-hen stock with a simulation program developed by our team. During modelling we take individual cost elements and the most significant factors (different forage costs, price of sold eggs, unsuitable eggs, installing day-old chicks and old animals) affecting returns into consideration. The results can be presented in tables and graphs for both sexes as well.... |
