The constraint on public debt when
In most advanced economies over the past decade real interest rates have been decidedly below the growth rate of the economy, while estimates of the marginal product of capital remain above it. Thus,
Fiscal Policy with High Debt and Low-Interest Rates
Policymakers in the United States face a combination of high and rising federal debt and low current and projected interest rates on that debt. Rising future debt will reduce growth and impede
Debt Sustainability When R – G < 0: No Free Lunch After All
