Scientific Bulletin – Economic Sciences No. 7 (13)Employment of labour in models of economic growthUniversity Lecturer PhD Cristina BÂLDANPhD Student Victoria- Mihaela BRÎNZEAFaculty of Economics, University of Pitestimihaelabranzea@yahoo.comAbstract:The economic growth resources represent the potential of useful mineral substances, ofhuman potential (population of working age), of scientific research and the financialpotential of the society at a certain time. Resources are becoming economic growth factorsthat are used in order to determine real possibilities of the society development. Economicgrowth expresses a complex process of evolution over a long period, which is manifestedby an increase of the characteristic dimensions of a national economy. An economic growthsupposes not only an increase of production, but also an upward and sustainable movement.Keywords: Economic Growth, economic factors, labour1. General considerationsIntegration of labour within the economic model was developed, to a certain extent, byclassical economists, who related it to the population as a prerequisite, but also as a restriction ofeconomic developments. The first complex model of dynamic economic analysis is an extensivebreeding scheme developed by Marx, in which extensive breeding problems of the workforce arecovered under the double aspect, quantitatively and qualitatively. However, the use of large-scalemodeling of economic growth is more recent.In general, in terms of statistical-mathematical construction, models are distinguished inmonofactorial (monosectorial), multisectorial and bisectorial ones.In bifactorials models - preferred by the neoclassics, but also used by someneokeynesians - capital and labour inputs are treated as separate substitutable among themselveswithin certain limits. Both labour and capital are carriers and beneficiaries of technical progress.Bisectorial and monosectorial models have been extended to the multisectorial-modeland although the complex construction involves difficulties in solving, they are usually rated asmore realistic.Usually, all models are monosectorial based type factors, relying on the assumption thatthere is a relationship of dependency among the results (Q), the aggregated factors - labour (L),funds production (K), and in some cases, natural resources:Q = f (L, K)In the analysis based on the production, macroeconomic bifactorial based production (Q)is the result of two key factors - labour (L) and capital (K) - as factors of production. Since anyrelation to the production includes a specific definition of technical progress, the EconometricModel is a model reflecting growth determined by the type and pace of this factor.Another feature of macroeconomic production function is that they assume as hypothesisthe degree of utilization of labour, which in some cases is that of full employment.Starting from the Cobb-Douglas classical production function, numerous models havebeen developed, including factor based models, in which employment can be a restriction or aresult of economic growth.82
