Ocean Fish Populations Contribution to the World Economy

  1. 1. Ocean Fish Populations Contribution to the World Economy Andrew J. Dyck & Rashid Sumaila July 2010
  2. 2. Ocean Fish Populaitons Contribution to the World Economy May 2009 Background  Fisheries worldwide are an important primary industry.  ‘landed-value’ of world fisheries estimated at $US 85 billion/yr (Sumaila, 2007).  Strong links with other sectors.  Boat building, management services, manufacturing.
  3. 3. Ocean Fish Populaitons Contribution to the World Economy May 2009 Objective  Determine the full economic impact of fisheries  Account for links between fisheries and the rest of the economy by considering indirect and induced effects
  4. 4. Ocean Fish Populaitons Contribution to the World Economy May 2009 Methods  Input-Output Approach  Country-by-country input-output tables  Sum direct, indirect and induced impacts of the fisheries sector for each coastal nation.
  5. 5. Ocean Fish Populaitons Contribution to the World Economy May 2009 Methods  Data is sourced from the Global Trade Analysis Project (GTAP) version 7.  Trade flows database with 57 sectors and 113 regions  Input-output tables mapped to 223 geo- political entities

  7. 7. Ocean Fish Populaitons Contribution to the World Economy May 2009 Methods: Economic Multipliers  Economic multipliers calculated  Economic output multiplier ( )  Income multiplier ( )  Type I multiplier: Includes direct and indirect effects  Type II multiplier: Includes Type I and induced effects [ ] 1− −AI [ ] 1− −AI Q y

  9. 9. Ocean Fish Populaitons Contribution to the World Economy May 2009 Total Economic Impact  Treat ‘landed-value’ as the sum of final demands for fisheries output.  Apply the multipliers to ‘landed-value’ and sum across regions.  Output:  Income: [ ]∑= − − N i ii LVAI 1 1 [ ] i N i i i i LVAI Q y ∑= − − 1 1

  12. 12. Ocean Fish Populaitons Contribution to the World Economy May 2009 Conclusion  ‘Landed-value’ for the year 2000 estimated at $US 85 Billion  Considering indirect and induced effects total contribution of the fisheries sector to the world economy is likely to be more than four times landed-value.
