New Keynesian theory identifies a set of principles central to the design and implementation of monetary policy. These principles rely on the ability of a central bank to manage expectations precisely, with policy prescriptions typically derived under the assumption of perfect information and...

"This paper explores the effects of central bank transparency on the performance of optimal inflation targeting rules. I assume that both the central bank and the private sector face uncertainty about the "correct" model of the economy and have to learn. A transparent central bank can reduce one...

Central bank communication plays an important role in shaping market participants’ expectations. This paper studies a simple nonlinear model of monetary policy in which agents have incomplete information about the economic environment. It shows that agents’ learning and the dynamics of the...

Central banks have become increasingly communicative. An important reason is that democratic societies expect more transparency from public institutions. Central bankers, based on empirical research, also believe that sharing information has economic benefits. Communication is seen as a way to...

This paper measures how the 2007-09 financial crisis affected the U.S. federal funds market. I accomplish this by developing and estimating a structural model of this market, in which intermediation plays a crucial role and borrowing banks differ in their unobserved probability of default. The...

In a floor system of monetary policy implementation, the central bank remunerates bank reserves at or near the market rate of interest. Some observers have expressed concern that operating such a system will have adverse fiscal consequences for the public sector and may even require the...

We study how monetary policy affects the funding composition of the banking sector. When monetary tightening reduces the retail deposit supply owing to, for example, a decrease in bank reserves or in money demand, banks try to substitute the deposit outflows with more wholesale funding in order...

We develop a model in which financial intermediaries hold liquidity to protect themselves from shocks. Depending on parameter values, banks may choose to hold too much or too little liquidity on aggregate compared with the socially optimal amount. The model endogenously generates a situation of...

This paper explores the role of capital flows and exchange rate dynamics in shaping the global economy's adjustment in a liquidity trap. Using a multi-country model with nominal rigidities, we shed light on the global adjustment since the Great Recession, a period when many advanced economies...
