We describe some of the main features of the recent vintage macroeconomic models used for monetary policy evaluation. We point to some of the key differences with respect to the earlier generation of macro models, and highlight the insights for policy that these new frameworks have to offer. Our...

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...

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...

We study the optimal monetary policy problem in a New Keynesian economy with a zero lower bound (ZLB) on the nominal interest rate, when the steady state natural rate (r*) becomes permanently negative. We show that the optimal policy aims to approach gradually a new steady state with positive...

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...
