  1. EwE Economics Beth Fulton 2012

  2. Simple bioeconomics • Costs and prices Prices x Costs x

  3. Spatial bioeconomics • Costs and catch in space = Ecospace

  4. Spatial bioeconomics • Differential implications of management Costs increased, but stocks high Costs unchanged, but stocks depleted

  5. Value Chains • Economic chains (potential amplification and knock on effects)

  6. Value Chains • Basic chain idea:

  7. Value Chains • In business theory has more aspects (not all covered in the EwE tool)

  8. SRL Fishers (3 types) Fish receivers Interim Transport Primary wholesale Secondary wholesale Export Destination Consumers ≈5% Tasmanian retailers 2% Tasmanian consumers Tasmanian Restaurants 3% Bass Strait ferry Melb. fish market 5% Interstate retailers Burnie airport 30% Lease quota fishers Australian mainland consumers 20-40 %* Pro-cessors (North & South) 70% Quota owner operators Interstate Restaurants Sydney fish market Chinese consumers Hobart airport Day fishers Chinese Importer 50-70 %* Vietnam Interim storage Re-packaging 20% ≈10% Philippines Tasmanian Southern Rock Lobster (SRL) * Australian sales and export figures vary by year By: Anna Farmery, Ingrid van Putten and Bridget Green (2012)

Fish receivers (drop off points) Interim storage Airfreight to processors TRL Fishery (3 sectors) TRL fisher types Export Destination Consumers Return to outer island Australian (mainland) consumers 17 t live Casual fishers 35% TIB (indigenous)fishers 5% Freezer & pond storage (on island) 37% Part –time fishers American importer American consumers Full-time fishers 65% Airfreight & Seafreight 383 t tails 45% Return to Thursday Island Freezer & pond storage (Thursday or Horn Island) Cairns processors Operating out of Thursday Island 45% 50% TVH (non-indigenous) fishers 37% Operating out of Queensland 55% Chinese Importer Chinese consumers Return mother-ship then Cairns Processor pick-up Cairns wharf 320 t live PNG fishers 25% Return to PNG Torres Strait Tropical Rock Lobster (TRL) Adapted from Hutton and van Putten et al (2012)

  10. Value Chains - Ecopath • Ecopath (& Ecosim) tool

  11. Value Chains – Defaults • Default chain available (aggregate for the whole system)

  12. Value Chains - Chains • Can define own chains (multiple chains)

  13. Producers • Parameterise producer economic values • Products ($/t) • Tickets ($/effort) • Revenue ($/effort) • Wages ($/t or %) • Taxes and Subsidies ($/t) • Workers (#/t) • Owners (#/t) • Social dependency (#/worker)

  14. Processors • Parameterise processor economic values • Products ($/t) • Wages ($/t or %) • Taxes and Subsidies ($/t) • Workers (#/t) • Owners (#/t) • Social dependency (#/worker)

  15. Transport • Parameterise transport economic values = distributors • Products ($/t) • Wages ($/t or %) • Taxes and Subsidies ($/t) • Workers (#/t) • Owners (#/t) • Social dependency (#/worker)

  16. Markets • Parameterise market economic values • Products ($/t) • Wages ($/t or %) • Taxes and Subsidies ($/t) • Workers (#/t) • Owners (#/t) • Social dependency (#/worker)

  17. Consumers • Easy bit….

  18. Spreadsheets • Or component entry • All the same parameters • Component type at a time

  19. Value Chains • Static outcome based on parameters & ecopath

  20. Value Chains – Through time • Dynamic outcome based on parameters & ecosim • No ecospace yet Revenue Profits Costs

  21. Value Chains – Example

  22. Value Chains – Example
