Government debt sustainability refers to the ability of a government to manage its debt levels without risking default or economic instability. This concept focuses on whether a government can meet its current and future debt obligations through its existing revenue sources while maintaining fiscal health. It plays a critical role in evaluating the effectiveness of fiscal policy, as unsustainable debt can lead to increased borrowing costs and reduced economic growth.

Review Questions
How does government debt sustainability relate to the effectiveness of fiscal policy?
Government debt sustainability is crucial for effective fiscal policy because it determines a government's capacity to finance its programs and investments without incurring excessive risk. If a government's debt becomes unsustainable, it may need to implement austerity measures or raise taxes, which can undermine the goals of fiscal policy aimed at stimulating economic growth. A sustainable debt level enables governments to respond flexibly to economic challenges, invest in public services, and maintain overall financial stability.
Evaluate the implications of a rising debt-to-GDP ratio on government debt sustainability.
A rising debt-to-GDP ratio can signify potential challenges for government debt sustainability, as it suggests that the nation's debt is growing faster than its economic output. This situation may lead to concerns among investors regarding the government's ability to repay its debts, increasing default risk and possibly raising borrowing costs. Additionally, a high ratio limits a government's ability to implement expansionary fiscal policies during economic downturns, potentially hampering recovery efforts and leading to prolonged periods of low growth.
Assess how interest rates influence government debt sustainability and what factors might affect these rates over time.
Interest rates play a significant role in determining government debt sustainability, as higher rates increase the cost of servicing existing debt. When interest rates rise, governments may face greater difficulties in managing their fiscal obligations, leading to potential refinancing issues or requiring cuts in spending. Factors that might affect interest rates include central bank policies, inflation expectations, and overall economic conditions. Understanding these dynamics is essential for governments seeking to maintain sustainable levels of debt while ensuring economic stability.
