Summary
African nations can increase fishing profits by 23% and boost fish biomass by 16% by forming a fishing cartel. This collective bargaining enhances economic and ecological outcomes for African countries.
Area of Science:
- Marine resource economics
- Fisheries management
- International trade
Background:
- African coastal waters are biologically rich but under-monetized from fishing rights sales.
- African nations individually negotiate fishing access, lacking collective market power.
- Foreign nations and fishers exploit these resources, often with greater returns.
Purpose of the Study:
- To model the economic and ecological impacts of an African fishing cartel.
- To assess the potential benefits of collective bargaining power in fisheries.
- To explore solutions for enhancing African nations' revenue from fishing rights.
Main Methods:
- Development of a bilateral oligopoly model.
- Simulation of a hypothetical African fish cartel.
- Analysis of market power dynamics between African sellers and foreign buyers.
Main Results:
- A cartel would lead to restricted catch, increasing fish biomass by 16%.
- African nations would see average profit increases of 23% due to shifted market power.
- Collective action significantly improves economic returns and ecological sustainability.
Conclusions:
- Forming a fishing cartel offers substantial economic and ecological advantages for African countries.
- Deeper African integration is a viable strategy to address economic and environmental challenges in fisheries.
- Overcoming individual negotiation disadvantages can unlock greater value from marine resources.
