  3. Fisheries values • Fisheries are a primary or ‘base’ industry • Source of resources out of which much economic activity grows. • How much economic activity throughout the economy is sourced from fisheries output? Dyck & Sumaila (2010)

  4. Approaches to capturing fisheries values • Input-output models; • Value chain models.

  5. Input-output model • This is a quantitative economic technique that represents the interdependencies between different branches of the national economy or between branches of different, even competing economies; • Wassily Leontief (1906-1999) developed this type of analysis and took the Nobel Prize in Economics for his development of this model.

  6. Matrix of inter-industry exchanges

  7. Economic impact of world fisheries output Dyck & Sumaila (2010)

  8. Income effect of world fisheries output Dyck & Sumaila (2010)

  9. Value chain approach Fisheries Sector Final Consumers Marine Ecosystems Intermediary Sectors EwE • Catch by species by gears; • Ex-vessel price; • fishing costs; • Subsidies. • Economic rent; • Final demand; • Number of jobs; • Household incomes.

  10. A simplified value chain • Reduced to 3 main sectors: • Primary sector; • Wholesale & processing sector; • Retail & food service sector. • For each sector, compute: • Input of raw materials/intermediary goods (in both volume and value); • Output of raw materials/intermediary goods/final products (in both volume and value); • Value-added/economic rent.

  11. A fish value chain schematic EwE (foreign) Import (landings) Import (products) Foreign Fisheries Final Consum. Landings (domestic) Fish Products EwE (domestic) Retail Domestic Fisheries Wholesale/ Processing Food Service Export (landings) Export (products)

  12. Value chain in EwE • Consider ecological, social, and economic consequences (and drivers) Christensen et al., 2010
