Supply equations for sawlog and pulpwood were developed with a panel of data from 102 Norwegian municipalities, observed from 1980 to 2000. Static and dynamic models were estimated by cross-section. time-series and panel data methods. A static model estimated by first differencing gave the best overall results in terms of theoretical expectations, pattern or residuals. prediction accuracy and p...
In percentile method, percentiles of the diameter distribution are predicted with a system of models. The continuous empirical diameter distribution function is then obtained by interpolating between the predicted values of percentiles. In Finland, the distribution is typically modelled as a basal-area weighted distribution, which is transformed to a traditional density function for application...
The study attempts to fill a gap in Malaysian forestry economics, an area relatively less probed compared to the other important primary commodities of Malaysia. The core of the thesis are two econometric studies. The first concerns estimating supply and demand elasticities of the three main Malaysian wood products sawlogs, sawnwood and plywood. Demand is split up into export and home demand to...
Studies about the impact of the timber trade on tropical forests have often oversimplified process complexity and underestimated regional variability. This study shows that forest degradation and clearing in Northwest Ecuador between 1983 and 1992 was closely linked to commercial logging. A key finding is that domestic demand is critical for shaping timber extraction and, hence, forest degradat...
Logging has been a much maligned feature of frontier development in the Amazon. Most discussions ignore the fact that logging can be part of a renewable, environmentally benign, and broadly equitable economic activity in these remote places. We estimate there to be some 4.5 +/- 1.35 billion m(3) of commercial timber volume in the Brazilian Amazon today, of which 1.2 billion m(3) is currently pr...
Abstract Forests provide an immense range of benefits to people, many which are not prioritized by forest policy because they difficult quantify. Wild foods from forests enhance the quality diets for those who consume them and income sell or trade them. The quantity wild food collected is challenging measure non‐standard units, seasonal differences in collection patterns large numbers species. ...
Trade policy influences the environment directly and indirectly, while environmental policies have an impact on competitiveness. In the past, trade's potential role to contribute to sustainable forest management has been largely unexplored. This paper is aimed at assessing the possible impacts of various policy instruments on trade and the environment. Although the Latin American and the Caribb...
