| This paper develops a dynamic model of crop production under uncertainty with intraseasonal input choices. Crop production involves multiple stages, including at least seeding, post emergence fertilizer/pesticide application and harvesting. If the farmer receives new information about the output and/or price during the stages, he may wish to adjust the input use at each stage in response to the future possible information. Whether future information leads to higher or lower input use at earlier stages depends on the production function, in particular whether inputs at different stages are substitutes or complements in the production function. |

| Declining salmon prices, due primarily to expansion of farmed salmon production, have reduced revenues for Alaska's wild salmon fisheries by roughly 62 percent over the past 10 years. One possibility for reversing this trend is to differentiate wild and farmed salmon in consumer markets through quality improvements and marketing. We use a simple conceptual model to highlight the challenges that Alaska's wild salmon industry must overcome before the industry is likely to see significant revenue gains from increased quality. Our tentative conclusion is that product differentiation could increase profits for wild salmon. However, implementation may require significant departures from traditional production and management practices and possibly an amendment to... |

| As Congress develops new farm legislation, some are lobbying for a new partnership between U.S. taxpayers and farmers. In exchange for an annual transfer of $10 to $20 billion from taxpayers to agriculture, farmers would do much more to enhance environmental quality. An attractive feature of a new partnership is that paying for an improved environment provides a clear and justifiable rationale for farm program payments, something that is lacking under current farm programs. By changing management practices and land use, farmers can provide cleaner water, cleaner air, better wildlife habitat, lower net greenhouse gas emissions, and improved long-run soil quality. Private profit maximizers largely ignore the value of these environmental goods. Hence, the... |

| This paper considers the problem of multiple-species fishery management when targeting individual species is costly and at-sea discards of fish by fishermen are unobserved by the regulator. A dynamic model is developed to balance the ecological interdependencies among multiple fish species, and the technological interdependence which captures costly targeting. Stock conditions, ecosystem interaction, technological specification, and relative prices under which at sea discards are acute are identified. Three regulatory regimes, species-specific harvest quotas, landing taxes, and revenue quotas, are contrasted against a hypothetical sole owner problem. An optimal plan under any of these regimes precludes discarding. For both very low and very high degrees of... |
