Articles containing the keyword 'references'

The purpose of this study was to examine the use or citations in Finnish forestry publications using source analysis. The material consisted of three of the four main series published in the field of forestry in Finland. The study was confined to three sample years in the middle of each decade during the period of 1910–1980.

The use of references in Finnish forestry sciences was abundant: from 30 to 60 references per report and from 1.1 to 1.7 references per page. The amount of self-citations varied from 6 to 9%. The half-time of the references was, in general, very long varying from 8–12 years in forest economics to 14–17 years in silviculture and forest biology. The amount of ”classical” publications was 4–11%. The amount to Finnish references was large varying from 30 to 59%. Anglo-Saxon series made 22–24%, Scandinavian 11–13%, German 7–9%, Russian 1–3% and French series less than one per cent of all references.

The process of capital accumulation in timber production has been examined in this study. A detailed explanation of new investment in forest industry in terms of productive capacity as the determinant of national forest policy target growing stock and silviculture is presented. The basis of the explanation of forest industry productive capacity was a linear vertically integrated input-output production model. The model was used to derive a macroeconomic equilibrium condition specifying forest sector aggregate demand as an integral part of the national economy. Timber production has been constructed as a state variable system and the Maximum Principle used to derive silvicultural investment criterion. The derivation of the investment criterion was formulated as a dynamic problem in a labour surplus economy with linkage between savings and choice of silvicultural technology defined via income distribution between wages and profit. Maximization of aggregate consumption was specified as the goal of timber production.

By assuming a state of sub-optimal savings rate, it is shown that the real cost of labour is not zero in a labour surplus economy. Because unemployment labour is not a free commodity, it is concluded that capital-intensive silvicultural technology represents an optimal means of maximizing aggregate consumption in labour surplus economy, contrary to the recommendation of social marginal productivity theory.
