| Título: | An Analysis of Ill-Posed Production Problems Using Maximum Entropy |

| Páginas: | pp. 124-38 |
| Año: | Feb. 1998 |
| Resumen: | Production economics problems are often ill-posed. This means that the number of parameters to be estimated is greater than the number of observations. In this article, the authors show how to recover flexible cost functions from very limited data sets using a maximum entropy approach. They also argue that there exists a continuum of analysis between mathematical programming and traditional econometric techniques which is based solely upon the available information. The limiting case of a multioutput cost function recovered using only a single observation of a farmer’s allocation decisions can be easily extended to handle more than one observation. |

| Título: | Modeling Regional Agricultural Production and Salinity Control Alternatives for Water Quality Policy Analysis |
| Fuente: | American Journal of Agricultural Economics. v.78, n.1. American Agricultural Economics Association |
| Páginas: | pp. 41-53 |
| Año: | Feb. 1996 |
| Resumen: | Water development and allocation to competing uses without well-defined water quality rights contribute to water use externalities. Federal legislation to address the salinity externalities in the Colorado River basin comprises a set of arbitrary quality standards and millions of dollars in federal projects. This study specifies economic criteria to empirically determine first- and second-best quality standards and to indicate opportunities for efficiency gains in existing policy. A basinwide, nonlinear programming model optimizes river water quality, resource allocation, production levels, and total expenditures for control. Revealed are the economic trade-offs between water uses, regions, and control strategies. |

| Título: | A Calibration Method for Agricultural Economic Production Models |
| Fuente: | Journal of Agricultural Economics. v.46, n.2. Agricultural Economics Society |
| Páginas: | pp. 147-59 |
| Año: | May 1995 |
| Resumen: | A method for calibrating agricultural production models is presented. The data requirements are those for a linear programming model with the addition of elasticities of substitution. Using these data, production models with a CES production function can be simply and automatically calibrated using small computers. The resulting models are shown to satisfy the standard macroeconomic conditions. When used for analysis of policy changes, the CES models are able to respond smoothly to changes in prices or constraints. Prior estimates of elasticities of substitution, supply or demand can be incorporated in the models. |
