Open access means that research outputs, such as articles and data, are free of restrictions on access and free of restrictions on use. In the light of recent market developments in academic publishing, we argue in this essay that the discourse about open access must include a discussion about research infrastructure and innovation in academic publishing.

This study examines foreign exchange intervention based on novel daily data covering 33 countries from 1995 to 2011. We find that intervention is widely used and an effective policy tool, with a success rate in excess of 80 percent under some criteria. The policy works well in terms of smoothing the path of exchange rates, and in stabilizing the exchange rate in countries with narrow band regimes. ...

This paper aims to verify results of the innovative study on gender identity for the USA by Bertrand et al. (2015) for Germany. They found that women who would earn more than their husbands distort their labor market outcome in order not to violate traditional gender identity norms. Using data from the German Socio-economic Panel Study (SOEP) we also find that the distribution of the share of income ...

The paper analyzes the integration of euro area sovereign bond markets during the European sovereign debt crisis. It tests for contagion (i.e., an intensification in the transmission of shocks across countries), fragmentation (a reduction in spillovers) and flight-to-quality patterns, exploiting the heteroskedasticity of intraday changes in bond yields for identification. The paper finds that euro ...

Die internationale Verflechtung der Finanzmärkte führt dazu, dass der Ausfall von Krediten in einem Land auch von Geldgebern in anderen Ländern getragen werden muss. Bei einer konsequenten Anwendung des Prinzips der Gläubigerhaftung würde der Vermögensverlust von dem unmittelbar betroffenen Kreditinstitut über dessen in- und ausländische Anteilseigner und Kreditgeber sowie deren Gläubiger bis zu den ...

We try to measure the impact work creation programs and rearmament had on employment and production of the German economy before World War II. Theoretically based on an extended version of the conventional input-output analysis, our model or analytical framework integrates the Keynesian multiplier into Leontief´s traditional model. Empirically, we apply our recently presented input-output table of ...

A growing literature uses changes in residual volatility for identifying structural shocks in vector autoregressive (VAR) analysis. A number of different models for heteroskedasticity or conditional heteroskedasticity are proposed and used in applications in this context. This study reviews the different volatility models and points out their advantages and drawbacks. It thereby enables researchers ...

Changes in residual volatility in vector autoregressive (VAR) models can be used for identifying structural shocks in a structural VAR analysis. Testable conditions are given for full identification for the case where the volatility changes can be modelled by a multivariate GARCH process. Formal statistical tests are presented for identification and their small sample properties are investigated via ...

Das Papier zeigt, dass die seit Jahrzehnten andauernde Klagen wissenschaftlich tätiger Ökonomen,dass Öffentlichkeit und Politik nicht genug auf Ergebnisse der ökonomischen Forschung hören,zumindest für Deutschland im Quervergleich zu anderen Wissenschaften in Bezug auf das medialeInteressen an ökonomischen Erkenntnissen nicht gerechtfertigt sind. Es wird in bemerkenswerterWeise von der Resonanz kontrastiert, ...
