We study the problem of a policymaker who seeks to set policy optimally in an economy where the true economic structure is unobserved, and policymakers optimally learn from their observations of the economy. This is a classic problem of learning and control, variants of which have been studied...

We examine optimal and other monetary policies in a linear-quadratic setup with relatively general forms of model uncertainty. The forms of uncertainty our framework encompasses include: simple i.i.d. model deviations; serially correlated model deviations; estimable regime-switching models; more...

This paper is a selective survey of new or recent methods to extract information about market expectations from asset prices for monetary policy purposes. Traditionally, interest rates and forward exchange rates have been used to extract expected means of future interest rates, exchange rates...

Using a small empirical model of inflation, output, and money estimated on U.S. data, we compare the relative performance of monetary targeting and inflation targeting. The results show that monetary targeting would be quite inefficient, with both higher inflation and output variability. This is...

Forward guidance about future policy settings, in the form of a published policy-rate path, has for many years been a natural part of normal monetary policy for several central banks, including the Reserve Bank of New Zealand and the Swedish Riksbank. The Swedish and New Zealand experience of a...

The monetary policy mandate for the Federal Reserve and of the Riksbank are essentially the same and boil down to stabilizing inflation around the inflation target and employment or unemployment around a long‐run sustainable rate. The relative weight on stabilizing unemployment or employment...
