This paper explores the menu of options for renormalizing public debt levels relative to nominal activity in the long run, should governments eventually decide to do so. Although debt ratios may need to rise further in some cases, a vision of longer-term options is key to weighing alternative medium-term stabilization strategies. Orthodox ones, the standard fare of officialdom, include enhancing growth, running primary budget surpluses, and privatizing government assets. Heterodox polices include restructuring debt contracts, generating unexpected inflation, taxing wealth, and repressing private finance. Advanced countries have relied far more on heterodox approaches than many observers choose to remember.

The Federal Reserve's mandate has evolved considerably over the organization's hundred-year history. It was changed from an initial focus in 1913 on financial stability, to fiscal financing in World War II and its aftermath, to a strong anti-inflation focus from the late 1970s, and then back to greater emphasis on financial stability since the Great Contraction. Yet, as the Fed's mandate has expanded in recent years, its range of instruments has narrowed, partly based on a misguided belief in the inherent stability of financial markets. We argue for a return to multiple instruments, including a more active role for reserve requirements.

Many emerging market economies are dollarized in varying degrees. How important is this for the conduct of monetary policy and choice of exchange rate regime? We propose a composite measure of dollarization, identify its major trends, and ascertain its impact on the effectiveness of monetary and exchange rate policy. We find that, contrary to the presumption in the literature, a high degree of dollarization does not pose an obstacle to monetary control or to disinflation. A high level of dollarization does appear to increase exchange rate pass-through, reinforcing the claim that "fear of floating" is a greater problem for highly dollarized economies.
