This study develops a model which can be used to evaluate the producer and consumer price effects of alternative methods of financing social security as well as the welfare effects on different types of households. Producer prices are determined by an input-output price model. Consumer prices are determined by domestic producer prices, import prices and value added taxes. An increase in employers social security contributions raises the price of household health care the most, and thus elderly people suffer the largest welfare loss. An increase in the value added tax rate raises mostly the prices of food, clothing and footwear, household maintenance goods, and recreation and culture. The welfare loss is largest in the group of two-parent families mainly because of their relatively large expenditure on food and household maintenance.
