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...
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...
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...
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...
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...
Management restrictions are simulated on streamside acres owned by private interests in western Oregon to assess forest inventory and log market implications. A dynamic, nonlinear optimization model of western Oregon's softwood log market simulates the resource and economic impacts of set-aside and minimum harvest age restrictions on forest acreage within...
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...
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...
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...
This study utilizes the Timber Assessment Market Model (TAMM) to examine the differences in Canadian softwood lumber market forecasts arising from econometric versus activity analysis supply curves. A restricted profit function approach is applied to three lumber producing regions using the most recent data available on costs, prices, and output...
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...
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...
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...
Although one of the most common problems facing the forest manager is the determination of management regime, there has been little effort to explicitly recognize the effect of harvesting technology and topography in the analysis. This study introduces a unified theory in harvesting in mountainous terrain which brings together silvicultural...
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...
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...
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...
