Using a series of examples, we review the various ways in which a monetary policy characterized by the Taylor rule can inject volatility into the economy. In the examples, a particular modification to the Taylor rule can reduce or even entirely eliminate the problems. Under the modified policy,...

A growing body of evidence finds that policy reaction functions vary substantially over different periods in the United States. This paper explores how moving to an environment in which monetary and fiscal regimes evolve according to a Markov process can change the impacts of policy shocks. In...

This paper discusses exchange rate rules in their role as macroeconomic instruments. Two quite different approaches are pursued. The traditional view is that exchange rate flexibility is a substitute for money wage flexibility so that managed money and managed exchange rates yield the necessary...

We explore the link between an interest rate rule for monetary policy and the behavior of the real exchange rate. The interest rate rule, in conjunction with some standard assumptions, implies that the deviation of the real exchange rate from its steady state depends on the present value of a...

Negative interest rates remain a controversial policy for central banks. We study a novel signalling channel and ask under what conditions negative rates should exist in an optimal policymaker’s toolkit. We prove two necessary conditions for the optimality of negative rates: a time-consistent...

Since their inception in 2013, inter partes review proceedings have steadily gained in popularity, killing patents at an astounding rate. It is no wonder that defendants flee to the PTAB when staring down costly patent infringement suits in district court. But IPR institution is not a right; it...

It is well known that the Fed can operate the optimal monetary policy if the Fed is able to trace the Natural-Rate-of-Interest (NRI) successfully. In this sense, it has been wondered if there could be a certain way practically available for the Fed to get it done. It is shown that, based on NRI...

Working with a small-scale calibrated New-Keynesian model, Coibion and Gorodnichenko (2011) find that the reduction in trend inflation during Volcker's mandate was a key factor behind the Great Moderation. We revisit this finding with an estimated New-Keynesian model with trend inflation and no...

This paper seeks to understand the behavior of Greenspan's Federal Reserve in the late 1990s. Some authors suggest that the Fed followed a simple 'Taylor rule,' while others argue that it deviated from such a rule because it recognized that the 'New Economy' permitted an easing of policy. We...
