Central banks no longer set the short-term interest rates that they use for monetary policy purposes by manipulating the supply of banking system reserves, as in conventional economics textbooks; today this process involves little or no variation in the supply of central bank liabilities. In...

I argue in this paper that one of the two forms of hitherto unconventional monetary policy that many central banks have implemented in response to the 2007 financial crisis - large-scale asset purchases, or to put the matter more generically, use of the central bank's balance sheet as a distinct...

Aggregate shocks that move output and inflation in opposite directions create a tradeoff between output and inflation variability, forcing central bankers to make a choice. Differences in the degree of accommodation of shocks lead to disparate variability outcomes, revealing national central...

Over the last two decades, communication has become an increasingly important aspect of monetary policy. These real-world developments have spawned a huge new scholarly literature on central bank communication -- mostly empirical, and almost all of it written in this decade. We survey this...

The influence of monetary policy over interest rates, and via interest rates over nonfinancial economic activity, stems from the central bank's role as a monopolist over the supply of bank reserves. Several trends already visible in the financial markets of many countries today threaten to...

The threat to monetary policy from the electronic revolution in banking is the possibility of a decoupling' of the operations of the central bank from markets in which financial claims are created and transacted in ways that, at some operative margin, affect the decisions of households and firms...

A feature of U.S. post-war business cycle experience that is by now widely documented is the tendency of the spread between the respective interest rates on commercial paper and Treasury bills to widen shortly before the onset of recessions. By contrast, the paper- bill spread did not anticipate...

Monetary policy is one of the two principal means (the other being fiscal policy) by which government authorities in a market economy regularly influence the pace and direction of overall economic activity, importantly including not only the level of aggregate output and employment but also the...

What stands out in retrospect about U.S. monetary policy during the Greenspan Era is the ongoing movement away from mechanistic restrictions on the conduct of policy, together with a willingness on occasion to depart even from what more flexible guidelines dictated by contemporary conventional...

The standard workhorse models of monetary policy now commonly in use, both for teaching macroeconomics to students and for supporting policymaking within many central banks, are incapable of incorporating the most widely accepted accounts of how the 2007-9 financial crisis occurred and incapable...
