ECONOMIC PRODUCTIVITY: FACTOR APPROACHES
Abstract. The article focuses on economic productivity and have stressed the theory of marginal utility (productivity). In modern researches such aggregate indicators as a total factor productivity and a multifactor productivity prevail. Total Factor Productivity is measured by combining the effects of all there sources used in the production of goods and services (labour, capital, materials, energy, etc.) and dividing it into the output. Multifactor productivity (MFP) is the ratio of total output to a subset of inputs. A subset of inputs might consist of only labour and materials or it could include capital. MFP is the residual contribution to output growth of an industry or economy after calculating the contribution from all its factor inputs. The OECD methodology examines key single-factor (aggregated) indicators of labour and capital productivity, considering total output and costs and, most importantly, the value added, which reflects the real increase in the welfare of the nation.
Key words: economic productivity, marginal utility, multifactor, total factor, output, inputs, capital, labor.
