  • 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...

  • 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...

  • 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 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...

  • Forest acreage trends in the Southeast : econometric analysis and policy simulations

    Creator:
    Alig, Ralph J.
    Abstract:
    The objective of this study was to develop a system based on economic criteria for projecting changes in land use areas. The total land base was partitioned among three classes of private forest owners and crop, pasture/range, and urban/other uses in the southeastern United States. The fraction of the land...

  • Nonindustrial forests, public policy and long-term timber supply in the South

    Creator:
    Brooks, David J.
    Abstract:
    Forest Service projections of the long-term supply and demand for forest products indicate that increasing importance will be placed on the supply behavior of nonindustrial private forest owners in the South. The inventory model on which these projections are based may produce biased estimates of southern timber production, however, as...

  • A comparison of subregional lumber, plywood and log markets in the Douglas-fir region

    Creator:
    Haven, Lisa
    Abstract:
    Subregional log market differences are defined and analyzed. Seven demand and seven supply centers are initially specified. Log demand factors inspected are mill capacity, processed wood species, cost and profitability conditions distinguished by product and subregion. They are preliminarily linked to a regional market model through product price transmission. An...

  • A policy model for Philippine timber product exports

    Creator:
    Canonizado, Jeremias A.
    Abstract:
    The Philippines relies heavily on timber product exports for its foreign exchange requirements. In recent years, however, it adopted log export restrictions as a hedge against the rapid depletion of its timber resources. Although conducted independently, its ASEAN partners (Malaysia and Indonesia), have likewise instituted similar restrictions on their own...
