Zhuk M. Mathematical modeling of households' economic activities.

The dissertation analyses theoretical foundations of the functioning of household as complex economic and social system at microeconomic and macroeconomic levels. First of all, we have analyzed interaction of elements of households system with the environment at macroeconomic and microeconomic level. Secondly, we have presented detailed classifications and definitions of households system of the country in general and for single household in particular. Thesis also deals with the structure of economic activities of the household. Respectively, the following economic activities have been allocated: consumption, saving, crediting, human capital development, participation in the labor market and household production. The results of the most recent theoretical as well as empirical studies about mathematical modeling of household behavior and economic activities were summarized. Model of household economic activities optimal management in continuous time, which unlike the existing ones takes into account a broader set of household functions such as: consumption, saving, crediting, human capital development, labor market participation and household production was developed. In order to improve methodology of classification of household loans and to forecast household credit category econometric multiple ordered choice model was estimated. Econometric binary choice model was developed to increase efficiency of estimation of borrower's solvency ratio. Unlike existing methods they take into account the impact of the financial status of all household members.
