Patunru, Arianto A.Athukorala, Prema-chandra2025-05-272025-05-270816-5181https://hdl.handle.net/1885/733754235The validity of the "?proportionality assumption' made in estimating value added in exports using aggregate input-output tables is tested using separately compiled domestic- and imported-input matrices for Indonesia, Thailand, Malaysia, Taiwan, and Australia. The results show that the use of the proportionality assumption results in overestimation of value-added exports, and that the magnitude of the bias becomes amplified when the export composition of a country shifts from primary products to manufactured goods through integration into global production networks.en-AUAuthor(s) retain copyright2019-01
