Abstract
The present paper reports on a study where Swedish input–output data are exploited for the first time to analyse changes over time in the requirements of labour, capital and imports per unit offinal output. Individual commodity groups and the whole of the economy are objects of analysis within the framework of the Leontief open static model. Total labour coeflcients declined for all but one of 26 commodity groups. Changes in the intermediate structure are in general of less importance than changes in direct labour coefficients. The hypothesis that imports were substituted for labour or labour-intensive domestic intermediates finds support in the data analysed. The increasing capital/labour ratios observed harmonize with the increasing costs of labour also registered for the period of study.
