Economic evaluation of projects and policies affecting anadromous fish : a simulation approach

Creator:: Hastie, James D.
Abstract:: Anadromous fish populations in the Pacific Northwest have undergone substantial change throughout the past century. Historical periods of over-harvest and the construction of numerous dams throughout the region have contributed to declines in the runs of naturally spawning stocks. Management efforts to rebuild fish populations have focused on the restriction...

Selecting optimum crop rotation

Creator:: El-Nazer, Talaat Y.
Abstract:: The crop rotation decision is important to farmers because of its impact on profitability, financing and risk exposure. This thesis addresses the problem of farm level crop rotation selection under perfect and imperfect knowledge of prices, yields and costs. The problem is addressed by first estimating production functions for irrigated...

Biased and unbiased estimation: an econometric application in the tuna industry

Creator:: Muangkoe, Marut
Abstract:: An econometric model of the canned tuna market is used to evaluate biased and unbiased estimators. Four methods for improving mean square error when multicollinearity is present in a regression equation are examined and compared with the results of ordinary least squares (OLS). Exact and inexact prior information methods are...

Market water transfers as a water quality policy : a case study of the Malheur River Basin, Oregon

Creator:: Connor, Jeffery D.
Abstract:: Agronomic research documents a strong correlation between the level of irrigation water applied and the level of farm chemicals leached into water bodies. Consequently, policies that cause farmers to alter irrigation water management practices are likely to influence water quality. Water markets are a potentially attractive method of addressing agriculturally...

The impacts of government market intervention on weed control technology, income and employment : a case study of basic grain farms in El Salvador, Central America

Creator:: Fonollera, R. E. (Raymundo E.)
Abstract:: El Salvador's land resources are intensively cultivated. Labor is relatively abundant and wages are low. This study analyzed the effects of government policies and observed farm price distortions on enterprise/weed control system choices and associated income-employment effects. A regional linear programming framework was employed to analyze the effects of alternative...
