  • Description:
    Often, economic contribution and competitiveness of an industry has been examined using measures such as exports and multipliers from a single-country input-output (IO) model. These measures will be inaccurate if production of goods traded among countries is highly fragmented across countries, and if the production requires a large share of intermediate inputs imported from abroad. To overcome the weakness of single-country input-output (IO) models, this study uses a multi-country input-output (MCIO) model when decomposing the global value added of fish production for ten selected countries generated along the global value chain (GVC), and developing measures of economic contribution and competitiveness of a country’s fishing industry. This study finds, among other things, that for some of the ten countries, the share of the global value added from fish production accounted for by foreign countries increases significantly over the 2000–2014 period, suggesting their growing dependence on foreign-sourced inputs. Overall, results indicate that countries exhibit a considerable heterogeneity in the direction and the magnitude of the change over the period in the MCIO-based multipliers and GVC income and employment.
