- The primary purpose of this paper is to analyse the short-run price responsiveness of wastepaper demand in Sweden for four different paper and board products, as well as any structural changes in demand behaviour for these products over time. The analysis is done within a variable Translog cost function model, and we employ data for individual paper and board mills over the time period 1974-1994. The results suggest that the short-run own-price sensitivity of waste paper demand is relatively high compared to those of other input factors, and it has also tended to increase over time for some of the paper products. In addition, wastepaper demand has also become more sensitive to changes in energy prices, and its use increases with increases in the price of energy. However, the relationship between wastepaper and woodpulp is more complex, and in many instances wastepaper and woodpulp are short-run complements. Overall this implies that price based recycling policies will be relatively successful in promoting wastepaper use, but they will not necessarily lead to the conservation of virgin forest resources.

- In this study, scale elasticity and optimal size of the Swedish sawmill industry is investigated.An input distance function is used to compute scale elasticity. The result of the study shows that the average scale elasticity is above 1, indicating existence of economies of scale in the industry. By comparing the size of the average input – output vectors with the inefficiency adjusted input vector and the output vector for scale efficient units, we could see that, in general, there are gains to be made by expansion. However, some units may gain from becoming smaller.
