PROFITABILITY OF LAND FACTOR ON THE CONDITIONS OF SUSTAINABLE DEVELOPMENT - FRAMES OF NEW LAND RENT THEORY.

Other papers concerning agricultural economics frequently emphasise a problem of low resource productivity. However, the measuring methods are controversial, because they do not consider a progressive depreciation of fixed assets in agriculture and the new utilities of land on the conditions of sustainable development. These preconditions entitle to formulate a hypothesis that a productivity of capital in agriculture in Poland is increasing because of intrinsic values of agricultural areas. This implies a need of rethinking the neoclassical land rent theories. The empirical objective of the article is an evaluation of capital productivity in agriculture in Poland in a long period to test a new land rent theory. The basis for the empirical verification of the hypothesis formulated by the author is a sectoral input-output analysis. Data from the input-output tables were used to evaluate capital productivity coefficients in agri-food sector. [ABSTRACT FROM AUTHOR]
