Recent monetary policy studies have shown that the trend productivity growth has non-trivial implications for monetary policy. This paper investigates how trend growth alters the effect of model uncertainty on macroeconomic fluctuations by introducing a robust control problem. We show that an...

The recovery from the Global Financial Crisis was characterized by sluggish output growth and by inflation remaining persistently below the inflation targets of central banks in many advanced economies despite an unprecedented monetary expansion. Ten years after the Global Financial Crisis, GDP...

Population growth rates have fallen considerably in most developed countries. An important question for monetary policy is whether this has led to a fall in the natural rate of interest. In representative agent models, the response of the natural rate to a fertility shock crucially depends on...

Inflation in advanced economies is low by historical standards but there is no threat of deflation. Slower economic growth is caused by supply-side constraints rather than low inflation. Below-the-target inflation does not damage the reputation of central banks. Thus, central banks should not...

Most macroeconomic models for monetary policy analysis are approximated around a zero-inflation steady state, but most central banks target inflation at a rate of about 2 percent. Many economists have recently proposed even higher inflation targets to reduce the incidence of the zero lower bound...

We theoretically explore long-run stagnation at the zero lower bound in a representative agent framework. We analytically compare expectations-driven stagnation to a secular stagnation episode and find contrasting policy implications for changes in government spending, supply shocks and...

This paper investigates how different monetary policy regime switching types impact macroeconomic dynamics. Policy switches that either affect the inflation target or the response to inflation deviations from target lead to different determinacy regions and different output, inflation, and...
