A Global Public Good (GPG) is a special kind of public good that offers non-excludable and non-rival benefits across the entire world. This means that no single individual or nation can be excluded from its advantages, and one person’s usage does not reduce availability for others. Classic examples include global climate regulation, the dissemination of knowledge, and the preservation of biodiversity.
Historical Context
The concept of GPG has evolved over time, influenced by several key events:
- Post-World War II Era: International cooperation led to the establishment of various organizations and frameworks promoting global welfare.
- 1990s: The term “Global Public Goods” gained prominence with the publication of key works by economists like Kaul, Grunberg, and Stern.
- 21st Century: Growing recognition of global challenges like climate change and pandemics emphasized the need for collective action.
Types/Categories
Global Public Goods can be broadly categorized into:
- Environmental Goods: Climate stability, biodiversity, ozone layer protection.
- Health: Global disease eradication, health research and vaccines.
- Knowledge: Open-access scientific research, global data sharing.
- Peace and Security: Nuclear disarmament, international peacekeeping.
Key Events
- The 1948 Universal Declaration of Human Rights: Marked a commitment to universal rights, a basis for many GPG.
- Kyoto Protocol (1997): A significant effort towards global climate change mitigation.
- Paris Agreement (2015): Another landmark accord focused on addressing global warming.
Detailed Explanations
Mathematical Models
GPG can be analyzed using various economic models. A common approach is the Samuelson Condition for public goods:
Where MRS is the Marginal Rate of Substitution (benefit to individuals) and MRT is the Marginal Rate of Transformation (cost to society).

Importance and Applicability
GPGs are crucial for:
- Sustainable Development: Addressing climate change and resource depletion.
- Public Health: Preventing and controlling global pandemics.
- Economic Stability: Providing a stable framework for global trade and cooperation.
Examples and Considerations
Examples:
- Global Climate Regulation: Efforts to limit carbon emissions benefit all nations.
- Knowledge Sharing: Open-access journals and international research collaborations enhance global scientific progress.
Considerations:
- Free Rider Problem: Nations may underinvest in GPGs, expecting others to bear the cost.
- Coordination: Effective provision requires extensive international cooperation.
Related Terms with Definitions
- Global Commons: Natural resources accessible to all, such as oceans and the atmosphere.
- Global Warming: The increase in Earth’s average surface temperature due to greenhouse gases.
