| El presente trabajo trata de evaluar los efectos externos de la erosión del suelo mediante el uso del método del Experimento de Elección (EE). Tras una breve revisión de la literatura socioeconómica sobre el problema de la erosión y de los métodos empleados para evaluar sus efectos, se describe una aplicación a la evaluación de los efectos externos de la erosión del suelo en la cuenca del Alto Genil (Granada). El empleo del método del EE permite el cálculo de los valores asociados a los impactos más importantes de la erosión, así como proporcionar al administrador público información útil para la determinación de prioridades de gestión en el contexto de la planificación territorial. También se estima la variación de bienestar que la aplicación de políticas... |

| Aquaculture, or more generally fish farming, and fisheries interact in several different ways. First, many types of fish farming require fish products as inputs, mostly for feeding purposes. Second, farmed fish and wild fish products compete in fish markets with consequences for both the industry and, of course, consumers. Third, fish farming generates various types of polluting agents that may affect wild fish stocks and their habitat. Several other interactions exist. This paper is primarily concerned with the implications of the first of these interactions, namely the input relationships, for the overall supply of fish products in the future. To the extent that the fish farming industry demands wild fish products such as fish meal, fish oil, etc.... |

| The increasing resistance of harmful biological organisms (bacteria, parasites, and pests) to selection pressure from the widespread use of control agents such as antibiotics, antimalarials, and pesticides is a serious problem in both medicine and agriculture. Modeling resistance-or, conversely, the effectiveness of these control agents as a biological resource-yields insights into how these agents should be optimally managed to maximize their economic benefit to society. This paper uses a model of evolution of bacterial resistance to antibiotics-in which resistance places an evolutionary disadvantage on the resistant organism-to develop a simple sequential algorithm of optimal antibiotic use. Although the solution to this problem follows the... |

| The purpose of this research report is to identify the appropriate market benchmark price to use to evaluate the pricing performance of market advisory services that are included in the annual AgMAS pricing performance evaluations. Five desirable properties of market benchmark prices are identified. Three potential specifications of the market benchmark price are considered: the average price received by Illinois farmers, the harvest cash price, and the average cash price over a two-year crop marketing window. The average cash price meets all of the desired properties, except that it would not be easily implementable by producers. It can be shown, though, that the price realized via a more manageable strategy of "spreading" sales during the marketing... |

| Cogonagrass (Imperata Cylindrica), an invasive weed, is a threat to slash pine forests. Using a dynamic optimization model, we estimated the impact of cogongrass on the profitability of slash pine forestry under four scenarios: no threat of cogongrass infestation; infestation is uncertain, and no control measures are taken; infestation is uncertain, but control measures are undertaken by one landowner but not the neighbors; and infestation is uncertain, and control measures are undertaken by everyone. Results indicate that annual net returns per acre under each scenario, respectively, are $25.30, $16.97, $13.89, and $17.38. Results suggest fostering a cooperative behavior among landowners is desirable. |

| The Uruguay Round trade negotiations completed in April 1994 reduced beef trade barriers. Trade barriers for beef products have historically been significant. The Uruguay Round essentially converts many nontariff barriers (quotas) to tariffs (tariffication), includes safeguards for import surges, establishes minimum access commitments, reduces domestic subsidy supports, and provides special tariff allowances for developing countries. These provisions, commensurate with a growing world demand for animal source proteins, will likely increase U.S. fed beef exports and ground beef imports. The United States is a major world producer as well as exporter of beef. In 1996, the United States represented 35 percent of world beef production (ranked first) and 28... |

| Using annual Japanese fresh fruit import data from 1971 to 1997, this study analyzes the import patterns of Japan's seven most popular fresh fruits by implementing and testing a general differential dmand system that nests four alternative import demand specifications. When tested against the general system using the five-good case (bananas, grapefutis, oranges, and lemons and aggregating pineapples, berries, and grapes), the analysis rejects the Almost Ideal Demand System and National Bureau of Research specifications but does not reject Rotterdam and Central Bureau of Statistics models. When estimated using the six-good case (bananas, grapefuits, oranges, lemons, and pineapples and aggregating berries and grapes), the analysis rejects all... |

| In this paper we build up the analysis of La Porta et al. (1998), to investigate the importance of legal families in explaining the variations in pollution emissions in different countries. The main intuition behind our analysis is that the nations in which the rights of shareholders are more protected, promote real and financial investment; this increases the speed at which the per-capita income corresponding to the declining branch of the Environmental Kutznets Curve (EKC) is achieved. In econometrics different regression analyses were performed using as dependent variables three different kinds of pollutants (CO2, fine suspended particulates and waste), including as an explanation some financial variables never before considered in this kind of study. |
