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...

We study the equilibrium properties of a business cycle model with financial frictions and price adjustment costs. Capital-constrained entrepreneurs finance risky projects by borrowing from banks. Banks, in turn, make loans using equity and deposits. Because financial contracts are not...

In this paper, we propose a new method to forecast macroeconomic variables that combines two existing approaches to mixed-frequency data in DSGE models. The first existing approach estimates the DSGE model in a quarterly frequency and uses higher frequency auxiliary data only for forecasting...

Motivated by VAR evidence, we develop a monetary DSGE model where an agency problem between bank financiers, stemming from limited liability and unobservable risk taking, distorts banks’ incentives leading them to choose excessively risky investments. A monetary policy expansion magnifies...

Motivated by VAR evidence on the risk-taking channel in the US, we develop a New Keynesian model where low levels of the risk-free rate induce banks to grant credit to riskier borrowers. In the model an agency problem between depositors and equity holders incentivizes banks to take excessive...

We explore the properties of welfare-maximizing monetary policy in a medium-scale DSGE model for Hungary. In order to make our results operational from a policymaker’s perspective, we approximate the optimal policy rule with a set of simple rules reacting only to observable variables. Our...

This paper investigates how government bond purchases affect leverage-constrained banks and non-financial firms by utilising a stochastic general equilibrium model. My results indicate that government bond purchases not only reduce non-financial firms' borrowing costs, amplified through a...

This paper compares the consequences of equity injections into banks with purchases of corporate and government bonds in a financial crisis situation using a New Keynesian model in which non-financial firms predominantly take non-market-based debt from banks instead of issuing securities. Our...
