This paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability. The paper first formalizes this problem and examines its microeconomic foundations. It...

Central banks affect the resources available to fiscal authorities through the impact of their policies on the public debt, as well as through their income, their mix of assets, their liabilities, and their own solvency. This paper inspects the ability of the central bank to alleviate the fiscal...

Analysis of quantitative easing (QE) typically focus on the recent past studying the policy's effectiveness during a financial crisis when nominal interest rates are zero. This paper examines instead the usefulness of QE in a future fiscal crisis, modeled as a situation where the fiscal outlook...

A new measure of credibility is constructed as a function of the differential between observed inflation and some estimate of the inflation rate that the central bank targets. The target is assumed to be met flexibly. Credibility is calculated for a large group of both advanced and emerging...

In this paper we provide empirical measures of central bank credibility and augment these with historical narratives from eleven countries. To the extent we are able to apply reliable institutional information we can also indirectly assess their role in influencing the credibility of the...

In spite of the mystique behind a central bank's balance sheet, its resource constraint bounds the dividends it can distribute by the present value of seignorage, which is a modest share of GDP. Moreover, the statutes of the Federal Reserve or the ECB make it difficult for it to redistribute...

A central bank is insolvent if its plans imply a Ponzi scheme on reserves so the price level becomes infinity. If the central bank enjoys fiscal support, in the form of a dividend rule that pays out net income every period, including when it is negative, it can never become insolvent...
