Serious fiscal vulnerabilities arising from many years of high government/GDP ratios have created new and complex interactions between public debt management and monetary policy. Although their formal mandates have not changed, recent balance sheet policies of many central banks have tended to...

Many commentators have argued that if the Federal Reserve had followed a stricter monetary policy earlier this decade when the housing bubble was forming, and if Congress had not deregulated banking but had imposed tighter financial standards, the housing boom and bust - and the subsequent...

Central banks repo market operations and liquidity infusions occasion a structural liquidity mismatch in bank balance sheets and increase the dependence on central bank liquidity. This paper argues for what I term “Circular Monetary Economics”, an approach to monetary policy that seeks to...

Recent developments in many industrialized countries have triggered a debate on whether monetary policy is effective when the nominal interest rate is close to zero. When the nominal interest rate hits its lower bound, the monetary authority is no longer in a position to pursue a policy of...

Leaning against the wind of credit booms is a monetary policy that is tighter than what is consistent with standard inflation targeting. This way the central bank tries to address excessive household debt. While the merits of such policy have been analysed, I argue that there are two dimensions...

This paper studies leverage regulation and monetary policy when equity investors and/or creditors have distorted beliefs relative to a planner. We characterize how the optimal leverage regulation responds to arbitrary changes in investors' and creditors' beliefs and relate our results to...

In the aftermath of the 2008 global financial crisis, it has been argued that monetary policy should prevent raising financial risk by responding actively to financial imbalances. This paper investigates the extent to which a central bank's reaction to financial instability may be incompatible...
