question
which of the following are considered international externalities?
select all that apply:
☐ threats to biodiversity around the world
☐ global warming
☐ property rights
☐ pollution tax

Explanation:

• Threats to biodiversity around the world: Biodiversity loss affects multiple countries and ecosystems globally. Species extinction or habitat destruction in one region can have ripple - effects on other regions (e.g., loss of pollinators that could impact agriculture in multiple countries).
• Global warming: It is a classic international externality. Greenhouse gas emissions from one country contribute to global temperature rise, which affects all countries (e.g., rising sea levels threaten low - lying nations regardless of their own emission levels).
• Property rights: Property rights are more of a domestic or private - law concept within a country's legal framework. They do not inherently represent an international externality.
• Pollution tax: A pollution tax is a domestic policy tool (imposed by a single country or a group within a country) to internalize pollution costs. It is not an international externality itself, but rather a measure to address domestic or local pollution (in some cases, if coordinated internationally, it could be part of a solution to an international externality like trans - boundary pollution, but the tax itself is not the externality).

Answer:

threats to biodiversity around the world, global warming
