1 EwE Economics Beth Fulton 2012

2 Costs and prices Simple bioeconomics Prices xCosts x

3 Costs and catch in space = Ecospace Spatial bioeconomics

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

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

6 Basic chain idea: Value Chains

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

8 SRL Fishers (3 types) Fish receivers Interim storage Pro- cessors (North & South) Chinese Importer Interim Transport Primary wholesale Secondary wholesale Interstate Restaurant s Sydney fish market Melb. fish market Export Destination Consumers Interstate retailers Tasmanian Southern Rock Lobster (SRL) Lease quota fishers Quota owner operators Day fishers Burnie airport Hobart airport Bass Strait ferry Australian mainland consumer s Chinese consumer s 20%20% 30%30% 70%70% 5%5% Tasmanian consumers Tasmanian Restaurants Tasmanian retailers 3%3% 2%2% 5%5% %* Vietnam Philippines Re-packaging 1 0% %* By: Anna Farmery, Ingrid van Putten and Bridget Green (2012) * Australian sales and export figures vary by year

10 Ecopath (& Ecosim) tool Value Chains - Ecopath

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

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

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

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

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

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

17 Easy bit…. Consumers

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

19 Static outcome based on parameters & ecopath Value Chains

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

21 Value Chains – Example
