Combining research into forest management stand conditions and wood supply chain processes has been missing from earlier forestry studies. There is a clear need to develop more cost-efficient small-diameter wood production, harvesting and transportation methods from first thinning, which could be used for either industrial or energy wood purposes. This study considers the total cost for small-diameter wood originating from young Scots pine (Pinus sylvestris L.) dominated stands. Pine pulpwood is the most harvested and most used roundwood assortment, use of which is expected to rise following new pulp-mill investments in Finland. In addition, utilisation of small-diameter trees directly for energy purposes has been increasing steadily in recent years. The aim of the study was to determine the cost-reduction potential of alternative forest management options and supply chains for small diameter-wood in the regional case of South Savo in eastern Finland. The total costs of three distinct scenarios were studied on the basis of forest management, first-thinning harvesting methods, and transportation: 1) industrial wood, 2) delimbed energy wood, and 3) whole trees for energy purposes. The cost-reduction potential for energy-wood supply chains from first thinning was compared to the industrial supply chain. Small-diameter delimbed wood delivered straight for energy purposes was found to be the most cost-efficient as far as the total cost of the supply chain is concerned. More cost-efficient small-diameter wood processes can be found by linking forest stand simulations with supply chain analysis.
The article is a review on the costs of raw materials in the Finnish sawmill industry in 1920s based on statistics collected from the members of the Central Association of the Finnish Woodworking Industries (now Finnish Forest Industries). The article includes statistics about the average size of if the saw timber bought in standing sales from private forests and harvested from the industry’s own forests, stumpage price of the timber, and labour costs of the harvesting of the wood. The average size of the logs was greater in the northern part of Finland, where the sawmills could limit the purchases of smaller timber. In the southern part of the country, the size of the timber decreased in 1922‒1926 due to growing demand of the timber. The long transport distances in the north influenced the costs. The number of logs per tree increased during the period. The level of stumpage price varied considerably in different parts of the country, falling from the south-west to the east and north. Competition of raw material increased the stumpage prices in 1922a and 1926‒27. The international economic downturn influenced the industry in 1929‒1931.

The existence and direction of causal relationships between the time series for the Finnish roundwood market for the period 1960–1994 is tested. Using simple bivariate analysis, we found evidence that for both logs and pulpwood, the lagged prices are helpful in forecasting quantity for the next year, but not vice versa. Saw log stumpage prices have significantly Granger-caused pulpwood prices over the business cycles, but the effect has diminished towards the present time. For quantities traded, the direction of causality was rather from pulpwood to saw logs. The consistency of bivariate test results was checked by the Granger-causality tests within trivariate VAR-models for both markets, and the results were found to be fairly similar to bivariate tests. The price fluctuations in the international markets for forest products have been found to be carried to domestic wood markets dominantly via the pulpwood part of the market.
The survey focuses on the stumpage prices of standing sales, where the buyer of the wood takes care of felling and transport of the timber. The study concentrates further on conifer sawn timber. The prices of the sawn timber rose continuously from 1891 to 1910. After 1913 the stumpage price fluctuations reflected the changes in the market. The article includes a detailed description on the changes of the saw timber in 1913-1922 and the factors affecting the prices. The prices are shown for different parts of the Finland. The first world war affects the prices and demand on saw timber in 1917-1918. In Northern Finland the prices of sawn timber increased slower than in Southern Finland. In general, the unfavorable factors have had stronger impact on the stumpage prices than the favorable.

This paper is a theoretical study of what is considered to constitute the proper perception of time in forest economics and management. A stumpage appraisal model that recognizes the influence of time is developed within the framework of a national aggregate economy. To demonstrate how a socially optimal land for timber production may be determined in a given nation, a stock-supply model is derived. The stumpage appraisal rule of development determines the market stumpage price that maintains a state of balance between timber production and other land use activities.

The aim of this paper was to study the nature of the relative areal differences in the Finnish forests in respect of timber yield, intensity of exploitation and stumpage prices. The yield index is the most inconsistent and the source of the greatest regional differences. The differences arise even in Southern Finland, as the yield in the South-West is only 80 % of that obtained in Eastern Häme. The areal variations in the wastage index are of the order of only 10 % at most, and the stumpage price index is relatively constant, remaining within the 10 % limit, as far north as the southern boundary of the province of Oulu.
Indices for the forest yield and final forest returns suggest that the further one goes in Finland the greater the discrepancy between the two, as a consequence of the increase in stumpage price differences. Thus, whereas the yield per hectare in North-Eastern Finland is about 20 % of that in Eastern Häme, the stumpage price is similarly only just over 50 % of that prevailing in the latter area. This, the resulting returns per hectare are only 10 % of those obtainable in the more southerly area. When the return per hectare for the Forestry Board District of Eastern Häme is represented by the index 100, one then obtains corresponding return indices of 21.0 for the Northern Ostrobothnia and Kainuu area, 13.0 for Lapland and 10.0 for North-Eastern Finland. Thus, it may be said that roughly 10 hectares of forest land in Lapland, 5 in Northern Ostrobothnia or Kainuu, or 2 in Northern Karelia or the coastal area of southern and central Ostrobothnia would be required to produce the same returns as 1 hectare in Eastern Häme. This represents an extremely wide range of variation within the borders of one country.
This work provides a clear and sufficiently accurate impression of the order of magnitude of the areal differences in returns from the Finnish forests, and may thus serve as an adequate basis for the taking of decisions in this field.
