We study the Beaudry and Portier (2006)-hypothesis of delayed-technology diffusion and news-driven business cycles. For German data on TFP and stock prices we find qualitatively similar empirical evidence. Quantitatively, however, an impulse response analysis suggests that a substantial part of...

According to most academics and policymakers, transparency in monetary policymaking is desirable. I examine this proposition in a small theoretical model emphasizing forwardlooking private sector behavior. Transparency makes it easier for price setters to infer the central bank's future policy...

The flow of information between futures and spot prices may vary over time, in particular during periods of stress. This article analyses the information content of the Bund Future and German government bonds during 1998 and test whether it is constant over time. The use of high-frequency data...

Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually to a monetary policy shock, ii) announced and credible disinflations are contractionary and iii) inflation...

This paper delineates the simultaneous impact of non-anticipated information on first and second moments of the intraday price process by including appropriate variables accounting for the news flow into both the mean and the variance function. This allows us to differentiate between the...

Ein Berater erfüllt einerseits die Rolle des Wissensvermittlers, andererseits kann er die Funktion übernehmen, bestehende Probleme und geplante Maßnahmen verschiedenen Interessensgruppen gegenüber zu legitimeren. Dieser Artikel zeigt empirische Evidenz für die Rolle des IT-Beraters auf...

We analyze contributions of different markets to price discovery on traded inflation expectations and how it changed during the financial crisis. The quicker information is processed on one market and the less one market is disrupted by the financial crisis the more valuable is its information...

If there is no such thing as a European Public Sphere (EPS), why don't we construct one? The answer seems to be obvious: There is no way one could construct a public sphere top-down since it depends on the active participation of speakers, the media and audience. In a democratic society they are...

The authors study a simple model of an asset market with informed and non-informed agents. In the absence of non-informed agents, the market becomes information efficient when the number of traders with different private information is large enough. Upon introducing non-informed agents, the...

We develop an agent-based financial market model in which agents follow technical and fundamental trading rules to determine their speculative investment positions. A central feature of our model is that we consider direct interactions between speculators due to which they may decide to change...
