پویایی های سیاست های پولی، بازده اوراق قرضه و بدهی

Using the government׳s intertemporal budget constraint, we quantify the contribution of returns paid on the U.S. government׳s debt portfolio to the evolution of the debt-to-GDP ratio. We show that announcements of unconventional monetary policy measures by the Federal Reserve between 2008.IV and 2012, as a part of macroeconomic stabilization, were associated with a sizable increase in returns and debt-to-GDP ratios and contributed to fiscal imbalances. We use the Federal Reserve׳s portfolio composition as a proxy for unconventional monetary policy measures and show that it is significantly related to future bond returns and fiscal balances.
