English title: On the distribution of income from Finnish sawn timber exports in 1913-1953.

The investigation studies the development of a logger’s daily earnings, a sawmill worker’s hourly earnings, saw timber stumpage prices and saw timber export prices, expressed in marks in Finland in 1913-1953, concentrating upon the trends of real value.

Although worker’s earnings in forestry and sawmilling have developed differently especially in the 1920s, the late 1930s and the early 1940s, their general long-time development has been very similar. On the other hand, the stumpage prices increased in real value much sharply than wages before the World War II. The real value of stumpage prices dropped because of economic regulation measures in the 1940s until regulation was abolished and the Korean War boom raised them in 1951, to fall after that. The development depends partly of the development of export prices for sawn timber.

Without changing the distribution of income from exports the real value of labour earnings, measured by export prices, may rise at most at a pace corresponding to the productivity of work. In logging there has been no actual increase in the productivity in the 20th century. As the increase in the productivity in timber transportation has probably been absorbed in increased wages and capital costs in the branch, a rise in forest labour’s real earnings and stumpage is possible only by means of a rise in the productivity of sawmilling or a change in the distribution of export income. It seems that from the end of World War I up to the middle of 1920s this increase of productivity and in export prices of sawn timber was shared only by capital and possibly mill labour. After that up to World War II stumpage prices rose so steeply that they swallowed the entire increase in productivity and reduced capital’s share of the export price. In the 40s the level of earnings followed the trend of productivity in industry, made possible by a sharp reduction in stumpage.

English title: Common alder forest in Kontusaari.
English keywords: Alnus incana; productivity

The aim of the study was to determine the value of common alder (Alnus glutinosa (L.) Gaertn.) in forestry by studying an unusually large alder forest in Kontusaari, an island of the size of 75 hectares in the Southern Finland. The forest is grass-herb forest site type. The coastline of the island is partly flooded. Wood has been harvested mainly for fuel wood. The stands have regenerated easily from stump shoots. The annual volume growth is slightly higher than what would be in Norway spruce (Picae abies (L.) Karst.) or Betula sp. stands, estimated based on growth and yield tables made by Ilvessalo. The site is well suited for common alder, and it is difficult to judge what the yield would be for other species on the site.

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander. The PDF includes a summary in German.

English title: Pressures for changes in the use of forests.

The paper discusses how the general trend towards increasing growth and productivity in the European societies is expressed also in forestry. It is reflected, for instance, in the increasing production and productivity of forest industries. Technological progress and call for economic growth require great flexibility from all resources. These pressures for effectiveness and production also concern Finnish forestry and forest management. Industrialization, urbanization and development of forestry have increased the pressure to use forests in recreation, preserving human environment and nature conservation in addition to production of timber. Through the development the definition of sustainability has become wider.

English title: Factors affecting logging productivity in farm forestry.

This is a fourth paper in a series of studies concerning logging in farm forests. The objective was to construct a model representing the productivity per farm of logging for delivery cuts. The first objective was to find out how the productivity of logging should be measured. In the study, combined labour and capital are regarded as the input.

Second object was to consider what variables to use in theory to determine the productivity of logging for delivery cuts. The factors affecting productivity depend on the concept of productivity employed. The productivity per farm of logging in delivery cuts can be determined both by regional and by farm variables. Still considering solely the effect of the quality of labour and capital input, the variables representing the person in charge of the delivery cuts are important explanatory farm variables. Others represent the farm totality (size, lines of production etc.).

Third aim was to develop a statistical-mathematical method suitable for constructing the model. Possible methods include regression analysis, which is, however, not the best method when there is large number of different levels to explain, or factor analysis. The suitable method to use in constructing a model depicting the productivity of a farm, was considered to be to condense the explanatory variables into rotated orthogonal factors. After preliminary correlation analysis, estimates of the factors interpreted as rational were employed as the explanatory variables for selective regression analysis.

Last, the model was tried out against actual material collected per farm, and the hypotheses were tested.
