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...
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...
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...
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 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...
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...
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...
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...
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 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...
