LECTURE 15 – GAME THEORY AND THE FISHERIES
SLIDE 3: 1. COMPETITION FOR RESOURCES
• Many environmental problems and issues in natural resource management arise from:
Interactions between economic agents
SLIDE 4:
• Foreign carriers were not allowed to fish; which opened to only Canadians were able to catch the cods
• Family-owned boats
o That were involved in the industries
• Only Canadian boats involved in the zone
• Did not stray away foreign fishers to be outside of the zone; free to catch as much fish as they wanted
SLIDE 5:
• After 1986… pretty steep decline
• 1993: cod fishing banned
• Sharp reduction in quotas for other species
o Maritimes really haven’t recovered for this
o Even parts of Quebec still have not been bounced back
o Pretty profound impacts
▪ WHY → lack of corporation for the fisheries (Canadian + foreign)
▪ Now → endangered species
SLIDE 6: 2. STRATEGIC DECISIONS
• Normative: what should be done
• Positive: what is actually done
• Stakeholders only looked at their own bottomline… didn’t look at the resources
• Chessboard → seek the choices before the action; can lead to policies to avoid these pitfalls
• Everyone sees this as a competition; and everyone wants a better foot and rather than trying to corporate
SLIDE 7: 3. GAME THEORY
• Player: decision maker who has preferences over set of outcomes
o Each player has different motivations for their actions + preferences on what they will be doing
o E.g. international agreements
o Some can even have consequences (positive or negative)
▪ Important to look at the benefits of cooperating vs. not cooperating
SLIDE 8:
• Imperfect information
o Information was missing
o When the department of fisheries were still sure of the fish… that is part of the information of
what players were going to do
▪ E.g. guiding fishing efforts to the foreign fleets
SLIDE 9: 4. FISHER’S DILEMMA
