A major criticism against staggered nominal contracts is that they give rise to the so called "persistency puzzle" - although they generate price inertia, they cannot account for the stylised fact of inflation persistence. It is thus commonly asserted that, in the context of the new Phillips...

Following Driscoll and Holden (2004), I model forward-looking workers who consider it unfair if a wage adjustment fails to match past inflation. However, the present paper proposes a much larger effect by using the job finding rate as the measure of workers' opportunities outside the firm rather...

In this paper the author attempts an analysis of the current financial/economic crisis that is wider ranging and more fundamental than he has been able to find. For this purpose he reviews some social science literature that views the current crisis as an episode in the secular decline of the...

A transactions model of the demand for multiple media of exchange is developed. Some results are expected, and others are both new and surprising. There are both extensive and intensive margins to currency substitution, and inflation may affect the two margins differently, leading to subtle...

Previous research on the optimal size of a monetary policy committee (MPC) focused on theoretical analyses and experimental studies. These studies suggest that the ideal monetary policy committee may not have many more than five members. In this paper we conduct an empirical cross-country study...

The paper presented a study on the relationship between credit money and economic instability. The issue is of primary importance because, as it is generally stated, lower variability of output and inflation has numerous economic benefits. We address this problem by means of an agent-based model...

Empirical data indicate that firms tend to have below-average productivity upon entry and that they tend to experience post-entry productivity growth. I present a New Keynesian model with growth in firm-specific productivity and firm turnover that captures these two phenomena. The model predicts...

This paper studies the effects of credit supply disruptions in a dynamic stochastic general equilibrium (DSGE) framework. First, this paper examines the effects of credit supply disruptions in the business sector. The model with financially constrained households generates a bigger decline in...

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A sticky-price model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

We study the forecasting performance of three alternative large scale approaches using a dataset for Germany that consists of 123 variables in quarterly frequency. These three approaches handle the dimensionality problem evoked by such a large dataset by aggregating information, yet on different...
