| Cattle feeding enterprises operate amid variability originating in prices and production. This research explicitly models yield risks related to cattle feeding by relating the mean and variance of yield performance factors to observable conditioning variables. The results demonstrate that pen characteristics, such as entry weight, gender, placement season, and location influence the mean and variability of yield factors, defined as dry matter feed conversion, average daily gain, mortality, and animal health costs. Ex ante profit distributions, conditional on cattle placement characteristics, are derived through simulation methods to evaluate the effects of price or yield shocks on the distributional characteristics of expected profits. |

| The present study sets up a thought experiment calibrated to represent risks of a high-risk production activity (farming), and investigating whether the structure of risk aversion (i.e., the changes in absolute or relative risk aversion associated with changes in wealth) can be estimated with reasonable precision. Findings strongly suggest that typical production data are unlikely to allow identification of the structure of risk aversion. A flexible utility parameterization is found to worsen technology parameter estimates. Findings also indicate that even under a restricted utility specification, the quality of utility parameters estimated from small samples is very poor. |

| There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of productivity growth in agriculture is an essential input. Yet solid projections for this variable have proven elusive particularly on a global basis. This is due, in no small part, to the difficulty in measuring historical productivity growth. The purpose of this paper is to report the latest time series evidence on total factor productivity growth for crops, ruminants and non-ruminant livestock, on a global basis. We then follow with tests for convergence amongst... |

| A stochastic production frontier model was estimated to provide standard measurement of technical efficiency of the dual-purpose cattle system located in Zulia State, Venezuela. This system is based on local and low-cost inputs, but has been considered to be inefficient because of its low partial productivity indices when compared with those used in developed countries. Results indicate that the efficiency of this system is reasonably high, downplaying the general idea of inefficiency. Likewise, the efficiency of this system has the potential for improvement through public policies and managerial decisions based on the determinants of technical efficiency. |

| Firm panel data sets over the period 1993 to 2002 are used to estimate translog production functions with labour, capital and material inputs for 9 Spanish food industries. To tackle the endogeneity of the regressors, the generalized method of moments estimations is employed. The specification tests reject the instrument variables only for 1 out of 9 estimates. The remaining 8 industries show evidence of homogeneity and constant returns to scale. Only one industry exhibits complete separability of all pairs of factors and thus translog is preferred to Cobb-Douglas specification for 7 industries. Substitutability and complementarity between production factors in response to price changes are studied through Morishima and Shadow elasticities.... |

| This paper determined the optimal crop rotation in South Central Kansas. The model incorporated net return, risk, and water quality. In general, water quality improved as tillage was reduced within a rotation type and by adding an alfalfa rotation. The optimal crop rotation mixes included wheat, grain sorghum, soybeans, and alfalfa. |
