Introduction: Private Wealth and Public Debt
AbstractIn the economic area comprising the OECD countries plus China, almost half of private wealth consists of net public debt. Private wealth is nearly twice the size of private real assets. Due to the continuing rise in life expectancy, the share of public debt in private wealth is growing. As long as public debt does not become too great, real interest rates can be low, but positive in the twenty-first century. The main reason for this is private retirement planning in light of high life expectancy. Investment cannot keep up with increasing private saving. In the twenty-first century, public debt is a macroeconomic steering instrument. Fiscal policy uses it to ensure that a positive, but low real interest rate level continues to prevail.
