This paper considers a prototypical monetary business cycle model for the U.S. economy, in which the equilibrium is undetermined if monetary policy is ‘inactive? In previous multivariate studies it has been common practice to restrict parameter estimates to values for which the equilibrium is...

This paper develops a business cycle model with a financial intermediation sector. Financial wealth is defined as a predetermined state variable. Both, the additional sector of financial intermediaries and predetermination of financial wealth, affect the demand for real financial wealth. If real...

In the last months, the world's economies were confronted with the largest economic recession since the Great Depression. The occurrence of a worldwide financial market meltdown as a consequence originally stemming from of the crisis in the US subprime housing sector was only prevented by...

Das Papier untersucht auf der Grundlage der monetären Überinvestitionstheorien von Wicksell (1898), Mises (1912) and Hayek (1929, 1935) das Scheitern von geld- und finanzpolitischen Regeln zur Kontrolle von übermäßigem Geldmengenwachstum und ausufernder Staatsverschuldung. Es zeigt...

This paper studies the dynamic volatility properties of a monetary economy in which agents hold Rational Beliefs (see Kurz (1994), (1997)) rather than Rational Expectations. Except for this feature the examined Rational Belief Equilibrium (in short, RBE) is entirely standard: markets are...

Two dynamic sticky price models with monopolistic competition in the goods market are presented. In the first model, each intermediate goods producer faces quadratic costs of adjusting its nominal price as introduced by Rotemberg (1982); the second model incorporates staggered price setting as...

In this paper, we study Ramsey-optimal fiscal and monetary policy in a mediumscale model of the U.S. business cycle. The model features a rich array of real and nominal rigidities that have been identified in the recent empirical literature as salient in explaining observed aggregate...

When taken to examine disinflation monetary policies, the current workhorse DSGE model of business cycle fluctuations successfully accounts for the main stylized facts in terms of recessionary effects and sacrifice ratio. We complement the transitional analysis of the short-run costs with a...

This paper proposes a model that links households and firms, as usual, by markets for factors and goods and, additionally, by a banking sector that channels households' funds to firms and eliminates idiosyncratic risk. In equilibrium, agency costs and tax benefits of corporate debt are...

We develop a behavioral macroeconomic model in which agents use simple but biased rules to forecast future output and inflation. This model generates endogenous waves of optimism and pessimism (Animal Spirits") that are generated by the correlation of biased beliefs. We contrast the dynamics of...
