When the economy is in a liquidity trap and households have a precautionary motive to save against unemployment risk, adverse demand shocks cause severe deflationary spirals and output contractions. In this context, we study the implications of optimal monetary policy, which consists of keeping...

In low-rate environments, policy strategies that involve holding rates "lower for longer" (L4L) may mitigate the effects of the effective lower bound (ELB). However, these strategies work in part by managing the public's expectations, which is not always realistic. Using the Fed's large-scale...

In the aftermath of the financial crisis, it has been argued that a guideline for the design of the future policy framework should be to take the ‘a’ out of ‘asymmetry’ in the way monetary policy deals with asset price movements. Recent empirical evidence has suggested that the Federal...

This paper studies optimal bank capital requirements in a model of endogenous bank funding conditions. I find that requirements should be higher during good times such that a macroprudential "buffer" is provided. However, whether banks can use buffers to maintain lending during a financial...

In responding to the extremely weak global economy after the financial crisis in 2008, many industrial nations have been considering or have already implemented negative nominal interest rate policy. This situation raises two important questions for monetary theories: (i) Given the widely held...

The monetary economy has properties that cannot be analyzed using the tools of today's dynamic general equilibrium analysis. Keynes's economics, far from being an aberration in the otherwise orderly evolution of modern macroeconomics from Adam Smith's ideas about the "invisible hand", was a...

We develop a N-sector business cycle network model a la Long and Plosser (1983), featuring heterogenous money demand a la Bewley (1980) and Lucas (1980). Despite incomplete markets and a well-defined distribution of real money balances across heterogeneous households, the enriched N-sector...

This paper develops a model of an economy where bank credit supports both productive investment and individual consumption smoothing in the face of idiosyncratic income risk. Bank credit is constrained by bank equity capital. When policy-makers inject equity capital during financial crises, they...

We explore the dynamic effects of news about a future technology improvement which turns out ex post to be overoptimistic. We find that it is difficult to generate a boom-bust cycle (a period in which stock prices, consumption, investment and employment all rise and then crash) in response to...
