Review Questions

• How does national defense illustrate the characteristics of public goods?
  • National defense exemplifies public goods because it is both non-excludable and non-rivalrous. This means that once national defense is provided, all citizens benefit from its protection regardless of whether they contributed to funding it. Additionally, one person's safety does not diminish another's; hence, individual contributions to national defense may be underprovided in a free market due to the lack of incentives.
• Analyze the challenges associated with funding national defense in relation to other public goods.
  • Funding national defense presents challenges because it competes with other essential public goods like education and healthcare for limited government resources. Policymakers must balance the military budget against these needs, leading to debates about prioritization. High expenditures on national defense can strain budgets, potentially resulting in cuts to other areas critical for societal welfare.
• Evaluate the impact of evolving global threats on a country's national defense strategy and economic priorities.
  • As global threats evolve, such as the rise of cyber warfare or international terrorism, countries must reassess their national defense strategies accordingly. This can lead to shifts in economic priorities as governments allocate more resources towards advanced technologies or intelligence operations. The need for adaptive strategies reflects broader geopolitical changes, influencing how countries prioritize spending on both defense and domestic welfare.
