This paper aims to improve the value of capital income shares in the GTAP database. From the GTAP database 5, it appears that capital shares vary a lot over regions and sectors; they range from less than 10% till over 80%. Based on information from the OECD STAN database, we conclude that variation in capital incomes shares is less than suggested in the GTAP database. Moreover, accounting for income of self-employed substantially reduces capital income shares in some sectors.
