In a floor system of monetary policy implementation, the central bank remunerates bank reserves at or near the market rate of interest. Some observers have expressed concern that operating such a system will have adverse fiscal consequences for the public sector and may even require the...

This paper presents a portfolio model of asset price effects arising from large-scale asset purchases by central banks — commonly known as quantitative easing (QE). Two financial frictions, segmentation of the market for central bank reserves and imperfect asset substitutability, give rise to...

Credit booms sometimes lead to financial crises which are accompanied with severe and persistent economic slumps. Does this imply that monetary policy should “lean against the wind” and counteract excess credit growth, even at the cost of higher output and inflation volatility? We study this...

I study optimal monetary policy in a simple New Keynesian model with portfolio adjustment costs. Purchases of long-term debt by the central bank (quantitative easing; ‘QE') alter the average portfolio return and hence influence aggregate demand and inflation. The central bank chooses the...

During and after the Great Recession, the European Central Bank adopted unconventional monetary policies that are more or less uncontroversial in the literature. By contrast, its quantitative easing (QE) program that started in 2015 is highly disputed. The article evaluates the pros and cons of...

Inflation targeting involves using all available information in stabilizing inflation around some target rate (Svensson, 2003). Inflation is typically at the very end of the transmission mechanism and hence its determination is subject to much model uncertainty which the central bank will want...

In this paper, we present a monetary policy game in which the central bank has a private forecast of supply and demand shocks. The public needs to form its inflationary expectations and can make use of central bank announcements. However, because of the credibility problem that the central bank...

This study examines the problem that a central bank may face after exiting a monetary quantitative easing policy. It develops a simple dynamic optimization model of a central bank, which finds that if the bank needs to absorb a substantial amount of excess reserves when exiting, the monetary...

This study re-investigates the money supply determination process for Japan. The methodology of this study, which differs from previous studies, is constructed on the assumption of potential nonlinear (asymmetric) relations between money supply and monetary base via money multiplier. To this...
