National Income Statistics 1. Scope of Measurement The national income statistics estimate total economic activity in Korea (i.e., the productionandexpenditures of all economic agents,including households,enterprises,and thegovernment). Production boundary: goods are counted as output even when they are not meant for sale(e.g., when they are for self-consumption); whereas in the case of services, non-paid domesticworkand personal services(e.g.,for self-consumption)are excluded from the productionboundary. Illegaleconomic activities,such as smuggling,gambling,and prostitution,are likewisecurrently not included in national income, even though they should be captured as productionactivities for a comprehensive measurement of production and expenditures. 2. Methods of Measurement Estimationunder the output approach(production-side national income)is carried out asfollows. Nominalvalue-added is derived by first estimating the values of output and intermediateinput and then subtracting the value of intermediate input from that of output. If the value ofthe intermediate input cannot be determined separately, it is calculated using the value-addedratioobtained from the Bank of Korea’s quarterly and annual financial statement analysisreports. Statisticsunder the expenditure approach(expenditure-side national income)are estimateddirectly using a variety of raw data on the amounts of money spent on final products. Statisticsunder the income approach(income-side national income)are estimated using avarietyof raw data on the distribution of nominal value-added generated by production.Operatingsurplus,in contrast,is calculated by subtracting compensation of employees andother components from the nominal value-added
