| Herein we model the widespread dispersal and management of an invasive species as a weak-link public good. The risk of introduction is driven in part by economic activity, is influenced by policies directed at the risk, and economic activity responds/adapts to the risk. Framed around recent introductions and rapid spread of dreissenid mussels in the Western United States, we find three key results. First, partial equilibrium estimates of welfare loss are significantly overestimated relative to general equilibrium estimates. If ecosystem services and market goods are substitutes the partial equilibrium bias is greater than if they are compliments. Second, well-intended policies do not necessarily reduce overall risk; risk reduction actions can transfer risk... |

| Phytoremediation is the use of living plants, known as hyperaccumulators which absorb unusually large amounts of metals in comparison to other plants. The use of classical plant breeding and new molecular techniques offers great potential to develop crops with the ability to clean up polluted sites. While these technologies have gained widespread attention, prior to commercial development, there are risks that must be considered – only a few of which have received even modest examination. Therefore, the focus of this working paper is to explore specific risks associated with phytoremediation and suggest ways in which these risks can be managed so that new, novel, and innovative plant technologies may be applied to provide low cost and efficient... |

| Conservation reserve program (CRP) payments amount to several billion dollars annually. Payments are allocated to both remove land from production and to help farmers pay for conservation improvements. However, research examining whether farmers increase their utility with CRPs is limited. This paper uses simulation analysis and certainty equivalents to compare farming income to payments under the CRP. Farming income is a combination of crop production and government payments as specified in the 2002 Farm Bill. This analysis focuses on farms in three different counties in Kentucky. Results indicate that CRPs are good choices for many farmers. |

| The overall aim of this study is to empirically investigate the cost structure of a management agreement type agri-environmental instrument and to identify factors for cost variation over space and time. We control for the actual level of compliance by using compliance weighted average scheme cost ratios. Beside technological and economic performance measures, we also incorporate risk proxies. In addition, we consider unobserved heterogeneity or path dependency with respect to unknown administrative, spatial and farm specific factors. Hence, we try to disentangle random and fixed scheme cost effects by applying a bootstrapped mixed-effects regression approach using the empirical case of the Environmental Stewardship Scheme in the UK. Regional and sectoral... |

| This paper investigates borrowing decisions of rural households from a microfinance in Tigray, Ethiopia using household panel data on 5 years and a dynamic panel probit model. The theoretical model takes two types of risk involved in joint-liability lending explicitly into account: risk of partner failure and the risk of losing future access to credit. Empirical results show that these risks are important in explaining borrowing decisions. Another finding is that the probability of repeat-borrowing is higher than the probability of new participation, with possible implications that perceived joint-liability threats deter participation and easing stringent punishments might help poor households’ access to credit. |

| Farmer's willingness to voluntarily reduce insecticide use is not considered when regulatory approaches to environmental protection are proposed. Regulations that require behavior that would voluntarily be undertaken are excessive and economically inefficient. Using survey data from a contingent valuation scenario, we demonstrate the willingness of crop producers in four Midwestern states in the U.S. to trade yield losses for environmental risk reduction by eliminating an insecticide application. The mean acceptable yield loss for a sample of 1,138 producers in Illinois, Iowa, Nebraska and Ohio is $8.25 per acre. Acceptable yield loss increases with the rated importance of environmental goods (fish, birds, mammals, native plants and endangered species),... |

| German hog production responds only very limited to price fluctuations in the pork market. The hog production concentrates in a few regions though it does not depend on special natural conditions. Furthermore, the production volume does hardly vary over time. Relatively high market risks, sunk costs, and the flexibility of the decision maker to defer investments characterize decision problems hog production. Thus the real option approach is chosen to explain the inertia in production capacity. Using panel data of specialised hog farms from the German farm accountancy data network (FADN) an empirical investment model is estimated. Formally, the model has the structure of an ordered probit model. This approach allows to test for economic hysteresis in the... |

| Australian farmers operate in one of the most risky environment in the world. They have to cope with various sources of risk in their businesses. This paper reports results of two case studies undertaken to examine the issues of farming risks and risk management strategies in Australia. The first case study found that climate variability, financial risk, marketing risk, and personal risk were regarded as the major sources of farming risk in the Upper Eyre Peninsula of South Australia. The main management strategies used by farmers included diversifying varieties, minimising tillage, minimising area of risky crops and maximising area of the least-risky crop, having high equity, having farm management deposits and other off-farm investments, and "leaving... |

| The optimisation of production plans is an important topic in agriculture, often related to diversification and specialisation as the classical instruments of coping with production risk. Although the measurement of embedded risk is often inaccurate, it is nevertheless necessary for decision making to describe the common behaviour of different variables in a model. Imprecisely defined relationships influence the “right” choice, why it is important to find a good approximation of the real circumstances. In financial science, copula functions are frequently used instead of correlation coefficients to model joint price behaviour, because of the possibility to link the marginal distributions on multifarious ways. By now, agricultural science makes less use of... |

| This study examined the impact of ACGSF in stimulating growth and minimizing of risk in Agricultural lending in Bauchi State. Forty three (43) farmers were randomly sampled and data collected through the use of structured questionnaire. Data were analyzed using descriptive statistics, correlation and multiple regression analysis. The results showed that farmers farm size increased considerably (P>0. 001) after taking the loan and the farm in come also increased (P<0. 001) after taking the loan for an average of two seasons. The results also showed that the educational level of the farmers does not affect loan amount directly even though there is strong positive correlation between the level of farmers’ education and their ability to meaningfully... |
