Policy implications were derived based on the examination of standard measures such as price, expenditure and, substitution elasticities over time. Imports of unprocessed and processed timber were found to be price-inelastic, in contrast to fuelwood and timber-for-layers imports. Fuelwood imports were found to be expenditure-elastic while timber imports were expenditure-inelastic. Substitution possibilities initiated by changes in the import price of unprocessed or processed timber, appeared to increase in the early 1990s. 收起
