Will a catch share for whales improve social welfare?

Area of Science:

• Marine conservation
• Wildlife management
• Environmental economics

Background:

• Whales are impure public goods, meaning their benefits are non-excludable and non-rivalrous, leading to potential free-riding issues in management.
• Current management of transboundary wildlife resources with high non-extractive values faces challenges in capturing all non-market benefits.
• Catch shares, a fisheries management tool, have been proposed for wildlife, but their applicability to whales requires critical evaluation.

Purpose of the Study:

• To critique the proposal of using catch shares for managing transboundary wildlife resources, specifically focusing on whales.
• To identify and analyze the potential implementation challenges and consequences of a whale share system.
• To assess the potential impact of whale shares on overall societal welfare compared to the status quo.

Main Methods:

• Conceptual critique of catch share applicability to whale management.
• Analysis of potential economic and political ramifications of whale shares.
• Identification of implementation challenges including free-riding, market effects, and logistical issues.

Main Results:

• Whale shares may legitimize and expand international trade in whale meat, posing monitoring and enforcement difficulties.
• The system could alter the political economy of conservation, potentially increasing costs for non-governmental organizations (NGOs).
• Logistical challenges in quota definition and allocation would arise, irrespective of market expansion or contraction.

Conclusions:

• A whale share program faces significant implementation hurdles that could lead to suboptimal outcomes.
• These challenges, including market expansion and altered conservation incentives, may result in lower overall societal welfare than current management approaches.
• The proposal requires careful consideration of its potential negative externalities and unintended consequences for whale conservation and societal benefit.
