Abstract:
We use a panel of 16 OECD countries over several decades to investigate the effects ofgovernment debts and deficits on long-term interest rates. In simple static specifications, aone-percentage-point increase in the primary deficit relative to GDP increasescontemporaneous long-term interest rates by about 10 basis points. In a vector autoregression(VAR), the same shock leads to a cumulative increase of almost 150 basis points after 10years. The effect of debt on interest rates is non-linear: only for countries with above-averagelevels of debt does an increase in debt affect the interest rate. World fiscal policy is alsoimportant: an increase in total OECD-government borrowing increases each country'sinterest rates. However, domestic fiscal policy continues to affect domestic interest rates evenafter controlling for worldwide debts and deficits.
