​The paper concentrates on illustrating and assessing central banks' liquidity operations during the crisis that started in August 2007. In addition to the ECB, the central banks of Sweden, Switzerland, the United Kingdom, Australia, Japan, Canada and the United States are analyzed. During the...

We study the effects of model uncertainty in a simple New-Keynesian model using robust control techniques. Due to the simple model structure, we are able to find closed-form solutions for the robust control problem, analysing both instrument rules and targeting rules under different timing...

We investigate the role played by systematic monetary policy in tackling the real effects of uncertainty shocks in U.S. recessions and expansions. We model key indicators of the business cycle with a nonlinear VAR that allows for different dynamics in busts and booms. Uncertainty shocks are...

Do the prevailing unusually and persistently low real interest rates reflect a decline in the natural rate of interest as commonly thought? We argue that this is only part of the story. The critical role of financial factors in influencing medium-term economic fluctuations must also be taken...

We investigate the causes of the Finnish Great Depression, 1990-1993. We find that the collapse of the overheated financial and banking sectors starting in 1989 was the trigger of the economic crisis. Foreign shocks, which include the collapse of trade with USSR in 1991, can account for at most...

We investigate how the business, credit and interest rate cycles affect the monetary transmission mechanism, using state-dependent local projection methods and data from 18 advanced economies. We exploit the time-series variation within countries, as well as cross-sectional variation across...

Expectations play a central role in modern macroeconomics. The econometric learning approach, in line with the cognitive consistency principle, models agents as forming expectations by estimating and updating subjective forecasting models in real time. This approach provides a stability test for...
