The perils of nominal targets
A monetary authority can be committed to pursuing an inflation, price-level, or nominal output target yet systematically fail to achieve the specified goals. Constrained by the zero lower bound on the policy rate, the monetary authority is unable to implement its objectives when private-sector expectations stray away from the target in the first place. Low-inflation expectations become self-fulfilling, leading to multiple Markov equilibria. Private-sector expectations are anchored on a unique Markov equilibrium if the monetary authority is given a strong stabilization goal for the policy ...

A model of the federal funds market: yesterday, today, and tomorrow
The landscape of the federal funds market changed drastically in the wake of the Great Recession as large-scale asset purchase programs left depository institutions awash with reserves and new regulations made it more costly for these institutions to lend. As traditional levers for implementing monetary policy became less effective, the Federal Reserve introduced new tools to implement the target range for the federal funds rate, changing this landscape even more. In this paper, we develop a model that is capable of reproducing the main features of the federal funds market, as observed before ...

On the timing of monetary policy reform
This paper argues that there is a normative case for delaying policy reform. Policy design in dynamic economies typically faces a trade-off between the policy effects in the short and long term, and possibly across future states of nature. When the economy is in an atypical state or available policies are less flexible than ideal, this trade-off can be steep enough that retaining the status-quo policy in the short term and taking on the reform at a later date is welfare improving. In a simple New Keynesian economy, I consider monetary policy reform from discretion to the optimal targeting ...

Can the U.S. monetary policy fall (again) in an expectation trap?
We provide a tractable model to study monetary policy under discretion. We focus on Markov equilibria. For all parametrizations with an equilibrium inflation rate around 2%, there is a second equilibrium with an inflation rate just above 10%. Thus the model can simultaneously account for the low and high inflation episodes in the U.S. We carefully characterize the set of Markov equilibria along the parameter space and find our results to be robust.

Can U.S. monetary policy fall (again) into an expectation trap?
We provide a tractable model to study monetary policy under discretion. We restrict our analysis to Markov equilibria. We find that for all parametrizations with an equilibrium inflation rate of about 2 percent, there is a second equilibrium with an inflation rate just above 10 percent. Thus, the model can simultaneously account for the low and high inflation episodes in the United States. We carefully characterize the set of Markov equilibria along the parameter space and find our results to be robust, suggesting that expectation traps are more than just a theoretical curiosity.

A TRACTABLE MODEL OF THE DEMAND FOR RESERVES UNDER NONLINEAR REMUNERATION SCHEMES
We propose a tractable model of the demand for reserves under nonlinear remuneration schemes that can encompass quota systems and voluntary reserve target frameworks, among other possibilities. We show how such remuneration schemes have several favorable properties regarding interest-rate control by the central bank. In particular, wider tolerance bands can reduce rate volatility due to variations in the supply of reserves, both large and small, although they may curtail trading in the interbank market.

Output gaps: uses and limitation
The concept of resource slack is central to understanding the dynamics between employment, output, and inflation. But what amount of slack is consistent with price stability? To answer this question, economists define baseline values for unemployment and output known as the natural rate of unemployment and potential output. The concepts of output and employment gaps can be useful to economists in several ways. First, they often guide the inflation forecasts of Federal Reserve staff and other researchers and market participants. Second, some economists argue that employment gaps are a useful ...

Does the U.S. trade more widely than it appears?
Given the importance of international trade for economic growth, why in any given year do few U.S. firms export their wares, and why are most U.S. goods not traded with most countries? Roc Armenter presents some intriguing evidence suggesting the U.S. does export most of its products to most countries, just not very often.

Rational Inattention via Ignorance Equivalence
We present a novel approach to finite Rational Inattention (RI) models based on the ignorance equivalent, a fictitious action with state-dependent payoffs that effectively summarizes the optimal learning and conditional choices. The ignorance equivalent allows us to recast the RI problem as a standard expected utility maximization over an augmented choice set called the learning-proof menu, yielding new insights regarding the behavioral implications of RI, in particular as new actions are added to the menu. Our geometric approach is also well suited to numerical methods, outperforming ...

Sustainable monetary policy and inflation expectations
The author shows that the short-term nominal interest rate can anchor private-sector expectations into low inflation more precisely, into the best equilibrium reputation can sustain. He introduces nominal asset markets in an infinite horizon version of the Barro-Gordon model. The author then analyzes the subset of sustainable policies compatible with any given asset price system at date t = 0. While there are usually many sustainable inflation paths associated with a given set of asset prices, the best sustainable inflation path is implemented if and only if the short-term nominal bond is ...
