This thesis deals with the development of social insurance, specifically with health insurance and social security, from the standpoint of transfer of insurance-generated monies to the state budget. It presents the significance of social insurance in its current form and an analysis of the principal changes it has undergone in the last fifteen years. It particularly examines changes in the definition of participants in social insurance and changes in the use and structure of bases of measurement in individual insurance subsystems. This thesis also includes an analysis of these changes which seeks to analyze the past and potential impact of shifts in basic factors which influence the amount of money flowing from insurance to the state budget (such as minimum wage, average wage and number of paying participants) on individual participants in social insurance.
