We analyze the implications of changes in the trend growth rate for optimal monetary policy in the presence of search and matching unemployment. We show that trend growth in itself does not generate a trade-off for the monetary authority, but that it interacts importantly with the inefficiencies...

An immigration shock has an ambiguous effect on inflation. On one hand, aggregate consumption increases with a suddenly larger population; this “demand channel” creates inflationary pressures. On the other hand, the labor market becomes more slack as immigrants search for jobs, containing...

The existence of nominal rigidities and inflation differentials between countries offers two of the main rationales for an inflation buffer in a monetary union where monetary policy is oriented towards an area-wide inflation objective. Evidence accumulated since 2003 suggests that nominal...

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...

This paper studies price stability and debt sustainability when the real rate exceeds trend growth (r g) in a New Keynesian model with endogenous technology growth through R&D. Under debt-stabilizing ("passive") fiscal policy the Taylor principle is not sufficient for determinacy. Instead,...

Historically high levels of private and public debt coupled with already very low short-term interest rates appear to limit the options for stimulative monetary policy in many advanced economies today. One option that has not yet been considered is monetary financing by central banks to boost...
