  • An econometric analysis of output supply and input demand in the Oregon softwood lumber and plywood industries

    Creator:
    Guerrero Ochoa, Isabel G.
    Abstract:
    The present study employs a normalized restricted quadratic profit function approach to estimate lumber and plywood supply and Marshallian factor demand elasticities for four region-product combinations in Oregon for the period 1970-2010. The four log demand functions will be employed as the "demand side" of the log market model of...

  • Economic modeling of tropical deforestation in Antioquia (Colombia), 1980-2000 : an analysis at a semi-fine scale with spatially explicit data

    Creator:
    Orrego, Sergio A.
    Abstract:
    This dissertation used land rent theory and an economic model of land-use conversion to examine the main drivers of the deforestation occurred in Antioquia,Colombia, between 1980 and 2000. Land-cover information at a semi-fine scale (1:25,000) obtained largely from aerial photography was employed to calculate deforestation. In addition, free international databases...

  • The economics of carbon sequestration in western Oregon forests

    Creator:
    Im, Eun Ho
    Abstract:
    This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

  • Radiative forcing and forest climate policy

    Creator:
    Thompson, Matthew P.
    Abstract:
    This thesis is comprised of two manuscripts that relate to forest-based management strategies in the context of market-based climate change mitigation policies. The work questions the appropriateness of a singular focus on carbon sequestration given the albedo effect and its possible countervailing climatic impacts. Through a review of salient literature...

  • An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

    Creator:
    Helvoigt, Ted L.
    Abstract:
    The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...

  • Carbon flux patterns on U.S. public timberlands under alternative timber harvest policies

    Creator:
    Shanks, Alyssa V.
    Abstract:
    This study considers trade-offs between timber harvest and carbon sequestration on National Forest and other public lands by contemporaneously linking a model of public harvest and inventory to a carbon accounting system. The public harvest model treats three harvest scenarios. The first minimizes the cost of meeting harvest requests that...

  • Smallholder farmers’ decision making in farm tree growing in the highlands of Ethiopia

    Creator:
    Ayele, Zeleke Ewnetu
    Abstract:
    Past afforestation programs launched to promote private and community woodlots in rural Ethiopia have not been based on clear understanding of the incentives and constraints of smallholder farmers. This study investigated the characteristic differences between tree-growing and non-tree-growing farm households and identified factors influencing farmers’ tree-growing decisions from a farming...

  • An evaluation of two timber supply models for state assessments

    Creator:
    Sutfin, Thomas William
    Abstract:
    The objectives of this paper are to: (1) describe the structure and output of SHRUB and RMS8O, (2) evaluate their respective ability to satisfy the needs of a state level timber assessment, and (3) demonstrate their application to forest planning using the state of California as the focus of a...

  • An econometric model of hardwood lumber and stumpage markets in the United States

    Creator:
    Lange, William J.
    Abstract:
    Two econometric models were developed to forecast consumption, production, and price of hardwood lumber, and removals and price of hardwood sawlog stumpage. Four eastern U.S. regions were represented in the models. Hardwood lumber consumption by manufacturing, shipping, residential construction, and nonresidential construction industries was recognized. Hardwood sawlog stumpage removals from...

  • A model of Pacific Rim log and lumber markets : structure and projections

    Creator:
    Katz, Andres
    Abstract:
    To facilitate policy making and improve understanding of issues facing the New Zealand forest sector, a spatial equilibrium model was developed for log and lumber trade in the Pacific Rim. Regions included in the model were New Zealand, Chile, Australia, Japan, Eastern Canada, British Columbia: Coast and Interior, and the...
