This chapter reviews the role of temporary price and wage rigidities in explaining of the dynamic relationship between money, real output, and inflation. The key properties to be explained are that monetary shocks have persistent, but not permanent, effects on real output, and that the...

This paper compares different implementations of monetary policy in a new-Keynesian setting. We can show that a shift from Ramsey optimal policy under short-term commitment (based on a negative feedback mechanism) to a Taylor rule (based on a positive feedback mechanism) corresponds to a Hopf...

Ziel der vorliegenden Arbeit ist es zu prüfen, inwieweit unterschiedliche Varianten berechenbarer dynamischer Gleichgewichtsmodelle die empirische Evidenz zum monetären Transmissionsmechanismus nachbilden. Die zentrale Frage dieser Arbeit, inwieweit nominale Rigiditäten zu Trägheiten des...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...
