The optimal policy response to a low-probability extreme event is examined. A simple policy problem is solved for a sequence of different loss functions: quadratic, combined quadratic/absolute-deviation, absolute-deviation, combined quadratic/constant, and perfectionist. The Paper shows that,...

Weak public institutions, including high levels of corruption, characterize many developing countries. With a simple model, we demonstrate that institutional quality has important implications for the design of monetary policies and can produce several departures from the conventional wisdom. We...

This Paper explores the quantitative implications of an approach to monetary policy that gained prominence in the United States during the 1990s. Proponents of this approach recommend that, when inflation is moderate but still above the long-run objective, the central bank should not move...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

This Paper employs stochastic simulations of a small structural rational expectations model to investigate the consequences of the zero bound on nominal interest rates. We find that if the economy is subject to stochastic shocks similar in magnitude to those experienced in the US over the 1980s...

Canzoneri (1985) and Rogoff (1985) showed that imposing symmetric penalties on a central bank for deviations from an announced inflation target would reduce the Barro-Gordon inflation bias, but only at the expense of distorting the central bank’s stabilization effort. More recently, Walsh...

Central banks’ economic and political importance has grown in advanced economies since the start of the Great Financial Crisis in 2007. An unwillingness or inability of governments to use countercyclical fiscal policy has made monetary policy the only stabilization tool in town. However, much...

Understanding the degree of measurement error in the estimates of the output gap available to policymakers in ‘real time’ is important both for the formulation of monetary policy and for the study of inflation behaviour. For the United Kingdom, no official output gap series was published for...

In January 2000 the Swiss National Bank adopted a new monetary policy framework incorporating a price stability objective defined as (any rate of) CPI inflation below 2 percent. We contrast this framework with inflation targeting strategies and review the SNB’s policy decisions since its...
