Introduction into Macroeconomic Modeling Foundations*

The current paper attempts to describe the labor market parameter dynamics using a different method, namely the semi-Markovian processes. This method allows for the labor market study without the large fluctuations that occurred at a certain moment in time impinging upon the results of the future estimations. This method, like other statistic and econometric methods provide the economic agent with information for adopting long run decisions, through which possible development trajectories are drawn for economic, budgetary and financial strategies. The aim of this paper is to analyze the following issues: what is an economic model; economic models typology and the sequences of the numerical modeling process.
