Review Questions

• How does national defense function as a public good, and what challenges does this create for funding?
  • National defense functions as a public good because it is non-excludable; once provided, it benefits all citizens regardless of whether they contribute to its funding. This creates challenges such as free riding, where individuals may rely on the protection offered without paying taxes or supporting military expenditures. The government must find ways to incentivize contributions and ensure adequate funding while managing public perception of the necessity for strong defense measures.
• Discuss how national defense policies can create both positive and negative externalities for society.
  • National defense policies can generate positive externalities by fostering technological advancements that spill over into civilian sectors, enhancing overall economic productivity. Conversely, these policies may also lead to negative externalities such as heightened tensions with other nations or increased military spending that diverts funds from essential social programs. The balance between maintaining strong defense capabilities while minimizing negative impacts on society is crucial for sustainable policy-making.
• Evaluate the impact of international cooperation on national defense in terms of public goods and externalities.
  • International cooperation on national defense allows countries to share resources and strategies, effectively creating a stronger collective security framework that acts as a public good for all involved nations.

However, it also raises concerns about sovereignty and dependency on allies for national security. Understanding these dynamics is vital for navigating the complexities of modern geopolitics.
