We integrate banks and the coexistence of bank and bond financing into an otherwise standard New Keynesian Framework with capital, and derive the microfounded, bank-augmented IS and Phillips Curves for the corresponding two-sector economy. We study the interplay of monetary and macroprudential...

After the recent crisis, central banks deployed unconventional monetary policies (UMP) to affect credit conditions and to provide liquidity at a large scale. We study if UMP should still be used when economic conditions normalize. Using an estimated non-linear DSGE model with a banking sector...

The financial crisis proved strikingly that stabilizing the price level is a necessary but not a sufficient condition to ensure macroeconomic stability. The obvious candidate for addressing systemic risk is macroprudential policy. In this paper we study the optimal (Ramsey) monetary and...

This paper estimates a New Keynesian model of the U.S. economy over the period following the 2001 slump, a period for which the adequacy of monetary policy is intensely debated. To relate to this debate, we consider three alternative empirical inflation series in the estimation. When using CPI...

This paper investigates whether conventional interest rate policy of central banks is a suitable instrument to attenuate excessive mispricing in stocks as suggested by the proponents of a "leaning against the wind" (LATW) monetary policy. For this, we decompose the stock price into a...

This study analyzes if regionally affiliated Federal Open Market Committee (FOMC) members take their districts’ regional banking sector instability into account when they vote. Considering the period 1978–2010, we find that a deterioration in a district’s bank health increases the...

What are the macroeconomic consequences of changes in residential mortgage market loan-to-value (LTV) ratios? In a structural VAR, real GDP and business investment increase significantly following an expansionary LTV shock. The impact on residential investment, however, is contingent on the...

This paper introduces a theoretical model of an interbank market and a central bank that implements an interest corridor system in order to exert control over the overnight interbank rate. We analyze in how far interbank market frictions in the form of broadly defined transaction costs influence...

We integrate monetary policy-making by committee into a New Keynesian model to assess the consequences of the committee's institutional characteristics for inflation, output, and welfare. Our analysis delivers the following results. First, we demonstrate that transparency about the committee's...

Empirical data suggest that new rms tend to grow faster than incumbent firms in terms of their productivity. A sticky-price model with learning-by-doing in new firms fits this data and predicts that for plausible calibrations, the optimal long-run inflation rate is positive and between 0.5% and...
