  • 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...

  • Opportunity costs : irrigation vs. hydropower

    Creator:
    Ross, Mark
    Abstract:
    In recent years we have seen increasing debate over the allocation of PNW water resources. In particular there are conflicts over using the river system for irrigation vs. electricity production. Denying the hydroelectric system water implies higher costs to electricity consumers as producers substitute more expensive nonhydro resources. This research...

  • 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...

  • The economic effects of ozone on U.S. agriculture : a sector modeling approach

    Creator:
    Hamilton, Scott A.
    Abstract:
    Tropospheric ozone is a pollutant which has detrimental effects on crop yields. The level of ambient ozone can be reduced by environmental policy changes and enforcement. The purpose of this study was to estimate the welfare effects of such changes in ambient ozone using recently available plant response data and...

  • Risk modeling using direct solution of expected utility maximization problems

    Creator:
    Lambert, David K.
    Abstract:
    A model of agricultural decision making is developed and tested in this thesis. The expected value of utility evaluated under alternative outcomes is directly maximized in a nonlinear programming model. Two features of the model distinguished it from traditional risk programming models. First, alternative attitudes towards the assumption of risk...

  • Off-site costs of soil erosion in the Willamette Valley of Oregon

    Creator:
    Moore, Walter B.
    Abstract:
    Soil erosion is a major source of pollution in the United States. Erosion can cause both on-site and off-site damages. It has been argued that off-site damages are a significant component of soil conservation benefits and are currently not well known. Off-site effects of soil erosion are uncompensated externalities. Given...
