Review Questions

• Explain how the concept of national defense relates to the problem of incentives in collective action problems.
  • National defense is a classic example of a collective action problem, as it is a public good that benefits all citizens within a country, regardless of their individual contributions. The problem of incentives arises because each individual may have an incentive to free-ride on the efforts of others, rather than contributing their fair share to the collective defense effort. This can lead to suboptimal levels of national defense, as the total contribution falls short of what is needed to effectively protect the country. Overcoming this collective action problem requires government intervention, such as through taxation or mandatory military service, to ensure that all citizens contribute to the national defense effort.
• Describe how the evolving nature of national defense challenges has impacted the strategies and policies used to address them.
  • The traditional conception of national defense, focused primarily on military threats, has been expanded to include a wider range of non-military challenges, such as cyber-attacks, climate change, and pandemics. This shift has required governments to adopt a more comprehensive and multifaceted approach to national defense, involving not only military capabilities but also intelligence gathering, international cooperation, and the coordination of various government agencies and private sector entities. Policymakers must now balance the allocation of resources between traditional military capabilities and emerging threats, while also addressing the collective action problems that arise in addressing these complex and interconnected challenges.
• Analyze how the costs of national defense, as a significant portion of government spending, can create tensions and trade-offs with other public services and priorities.
  • The high cost of national defense, often consuming a substantial portion of government budgets, can create tensions and trade-offs with the funding of other public services and priorities, such as education, healthcare, and social welfare programs. Policymakers must navigate these competing demands and find a balance that ensures the country's security while also addressing the needs of its citizens. This can be particularly challenging in the context of collective action problems, where the benefits of national defense are widely shared, but the costs are borne by taxpayers. Addressing these trade-offs requires careful analysis, public debate, and the consideration of long-term economic and social implications, as well as the potential consequences of underinvesting in national defense or other critical public services.
