Background
In economics, the concept of a global public good plays a crucial role in understanding how certain benefits and resources are shared among the global population without prejudice. The nature of these goods ensures that no single individual or group can be excluded from their advantages and that one person’s use does not diminish availability to others.
Historical Context
The term “public good” has long been part of economic discourse. Formally defined by economists like Paul Samuelson in the 1950s, public goods are characterized by their inability to exclude non-payers (non-excludable) and the fact that one person’s consumption does not reduce the availability for others (non-rivalrous). Over time, the emergence of global issues such as climate change and pandemics highlighted the need to understand certain public goods on a global scale.
Definitions and Concepts
A global public good is a subtype of public good, characterized by the following:
- Non-Excludable: Benefits cannot be confined to paying customers.
- Non-Rivalrous: One individual’s consumption does not affect another’s.
Examples include, but are not limited to, knowledge dissemination, climate stability, and global health initiatives.
Major Analytical Frameworks
Classical Economics
Early classical economists did not fully engage with the concept of global public goods since their analysis predominantly dealt with national economies and classical public goods.
Neoclassical Economics
Neoclassical theory formalized the characteristics of public goods but treated global public goods with a similar intellectual approach by extending the principles to an international context.
Keynesian Economics
Keynesian policies related to public spending often include funding for basic research and international cooperation, thus implicitly touching on global public goods.
Marxian Economics
Marxian theory critiques the commodification of public goods and advocates for collective ownership, applying these concepts on a global scale with supports for shared global resources.
Institutional Economics
Emphasizes the role that institutions/collaboration play in providing global public goods, such as treaties on climate change or regimes controlling global pandemics.
Behavioral Economics
Looks into how individuals’ behaviors and decisions affect the provision and sustainability of global public goods.
Post-Keynesian Economics
Focuses on macroeconomic principles that underpin policy decisions regarding funding international projects.
Austrian Economics
While typically advocating for reduced government intervention, it conversely can argue for collective actions in cases where the free market cannot effectively manage global public goods.
Development Economics
Concentrates on countries’ economic development and considers global public goods like education, healthcare, and infrastructure critical for this process.
Monetarism
While focused primarily on the control of money supply, it acknowledges the need for collaborative efforts to maintain global economic stability, a form of a global public good.
Comparative Analysis
Global public goods often require a cooperative international effort for funding and management, contrasting with national public goods which may be funded through localized taxation.
