Should central banks, because of the zero-lower-bound problem, raise their inflation-rate targets? Several arguments are relevant. (1) In the absence of the ZLB, the optimal steady-state inflation rate, according to standard New Keynesian reasoning, lies between the Friedman-rule value of...

This paper reviews the rationale for quantitative easing when central bank policy rates reach near zero levels in light of recent announcements regarding direct asset purchases by the Bank of England, the Bank of Japan, the U.S. Federal Reserve and the European Central Bank. Empirical evidence...

This paper presents a prototype model for development of the fiscal theory of the price level.' In this simple setting, the fiscal theory's distinctiveness relies upon adoption of a bubble solution, rather than the rational-expectations fundamentals solution. The paper then shows that the fiscal...

This paper investigates the performance, in several small-scale models of the Japanese economy, of an operational monetary policy rule related to ones previously considered for the United States. The rule dictates settings of the monetary base that are designed to produce values of nominal GNP...

In analyses of "liquidity trap" problems associated with the zero lower bound (ZLB) on nominal interest rates, it is important to emphasize the difference between policy rule changes, intended to help escape an existing ZLB situation, and maintained policy rules designed so as to avoid ZLB...

Recent mainstream monetary policy analysis focuses on rational expectation solutions that are uniquely stable. A number of recent studies have examined the question of whether typical New Keynesian (NK) models, with policy rules that satisfy the Taylor principle, also exhibit solutions with...

It has become increasingly evident that the Federal Reserve's official strategy of the past decade, involving the adherence to target paths for monetary aggregates, is not currently being utilized to any significant extent. While some commentators welcome and others deplore this development,...

In this paper we investigate the comparative properties of empirically-estimated monetary models of the U.S. economy. We make use of a new data base of models designed for such investigations. We focus on three representative models: the Christiano, Eichenbaum, Evans (2005) model, the Smets and...

This paper compares the P-bar model of price adjustment with the currently dominant Calvo specification. Theoretically, the P-bar model is more attractive as it depends upon adjustment costs for physical quantities rather than nominal prices, while incorporating a one-period information lag....

In a very broad class of dynamic linear models, if agents possess knowledge of current endogenous variables in a least-squares learning process, determinacy of a rational expectations (RE) equilibrium is sufficient but not necessary for learnability of that equilibrium. Thus, since learnability...
