IWH-Makrometer: Neues Datenangebot soll Trends in der Wirtschaftsentwicklung der Bundesländer transparent machen
Das Institut für Wirtschaftsforschung Halle (IWH) ist im November 2014 mit einem neuen Datenangebot ans Netz gegangen: dem IWH-Makrometer. Es handelt sich dabei um eine neue makroökonomische Datenbank für die deutschen Bundesländer sowie für die Regionen West- und Ostdeutschland. Die Datenbank soll Trends in der Wirtschaftsentwicklung deutscher Regionen transparent machen und aktuelle Informationen über die Wirtschaftslage in Ostdeutschland be-reitstellen. Das Datenangebot des IWH-Makrometers besteht aus zwei Teilen: (1) Makrodaten interaktiv und (2) IWH-Indikatoren zur gesamtwirtschaftlichen Lage in Ostdeutschland.

Stellungnahme zum Gesetzesentwurf von CDU und FDP zur hessischen Schuldenbremse
Nach Ansicht des IWH ist das gewählte aggregierte Konjunkturbereinigungsverfahren zur Bestimmung des strukturellen Finanzierungssaldos in Hessen grundsätzlich geeignet. Zu kritisieren ist allerdings die Berücksichtigung einer Steuerabweichungskomponente, die manipulationsanfälliger und weniger transparent ist als alternative Verfahren. Auch fehlt in dem Gesetzesentwurf eine Frist für den Ausgleich des Kontrollkontos.

Has the Euro Increased International Price Elasticities?
Oliver Holtemöller, Götz Zeddies
Empirica,
No. 1,
2013
Abstract
The introduction of the Euro has been accompanied by the hope that international competition between EMU member states would increase due to higher price transparency. This paper contributes to the literature by analyzing price elasticities in international trade flows between Germany and France and between Germany and the United Kingdom before and after the introduction of the Euro. Using disaggregated Eurostat trade statistics, we adopt a heterogeneous dynamic panel framework for the estimation of price elasticities. We suggest a Kalman-filter approach to control for unobservable quality changes which otherwise would bias estimates of price elasticities. We divide the complete sample, which ranges from 1995 to 2008, into two sub-samples and show that price elasticities in trade between EMU members did not change substantially after the introduction of the Euro. Hence, we do not find evidence for an increase in international price competition resulting from EMU.

The Investment Strategies of Sovereign Wealth Funds
Shai B. Bernstein, Josh Lerner, Antoinette Schoar
Journal of Economic Perspectives,
No. 2,
2013
Abstract
Sovereign wealth funds have emerged as major investors in corporate and real resources worldwide. After an overview of their magnitude, we consider the institutional arrangements under which many of the sovereign wealth funds operate. We focus on a specific set of agency problems that is of first-order importance for these funds: that is, the direct involvement of political leaders in the management process. We show that sovereign wealth funds with greater involvement of political leaders in fund management are associated with investment strategies that seem to favor short-term economic policy goals in their respective countries at the expense of longer-term maximization of returns. Sovereign wealth funds face several other issues, like how best to cope with demands for transparency, which can allow others to copy their investment strategies, and how to address the problems that arise with sheer size, like the difficulties of scaling up investment strategies that only work with a smaller value of assets under investment. In the conclusion, we discuss how various approaches cultivated by effective institutional investors worldwide -- from investing in the best people to pioneering new asset classes to compartmentalizing investment activities -- may provide clues as to how sovereign wealth funds might address these issues.

Foreign Bank Entry, Credit Allocation and Lending Rates in Emerging Markets: Empirical Evidence from Poland
Hans Degryse, Olena Havrylchyk, Emilia Jurzyk, Sylwester Kozak
Journal of Banking and Finance,
No. 11,
2012
Abstract
Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.

Evaluating Communication Strategies for Public Agencies: Transparency, Opacity, and Secrecy
Axel Lindner
B.E. Journal of Macroeconomics,
2009
Abstract
This paper analyses in a simple global games framework welfare effects stemming from different communication strategies of public agencies if strategies of agents are complementary to each other: Communication can either be fully transparent, or the agency opaquely publishes only its overall assessment of the economy, or it keeps information completely secret. It is shown that private agents put more weight on their private information in the transparent case than in the case of opacity. Thus, in many cases, the appropriate measure against overreliance on public information is giving more details to the public instead of denying access to public information.

Dynamic Order Submission Strategies with Competition between a Dealer Market and a Crossing Network
Hans Degryse, Mark Van Achter, Gunther Wuyts
Journal of Financial Economics,
No. 3,
2009
Abstract
We analyze a dynamic microstructure model in which a dealer market (DM) and a crossing network (CN) interact for three informational settings. A key result is that coexistence of trading systems generates systematic patterns in order flow, which depend on the degree of transparency. Further, we study overall welfare, measured by the gains from trade of all agents, and compare it with the maximum overall welfare. The discrepancy between both measures is attributable to two inefficiencies. Due to these inefficiencies, introducing a CN next to a DM, as well as increasing the transparency level, not necessarily produces greater overall welfare.

Does too much Transparency of Central Banks Prevent Agents from Using their Private Information Efficiently?
Axel Lindner
IWH Discussion Papers,
No. 16,
2007
Abstract
This paper analyses in a simple global games framework welfare effects of different communication strategies of a central bank: it can either publish no more than its overall assessment of the economy or be more transparent, giving detailed reasons for this assessment. The latter strategy is shown to be superior because it enables agents to use private information and to be less dependent on common knowledge. This result holds true even if the strategies of agents are strategic complements, for which case it has been argued that too much transparency might induce agents to neglect their private knowledge.

Geldpolitische Strategien im Umbruch
Diemo Dietrich, Albrecht F. Michler
Systeme monetärer Steuerung - Analyse und Vergleich geldpolitischer Strategien. Schriften zu Ordnungsfragen der Wirtschaft, Band 86,
No. 86,
2007
Abstract
In recent times the strategies of monetary policy, in particular that of the ECB, have been in the limelight of both scientific and public attention. After introducing into conceptual basics of monetary policy strategies, we compare inflation targeting and monetary targeting as the two prevalent strategies. The criteria established for this comparison are the way how the transmission of monetary policy is modeled, the role of expectations, the meaning of a nominal anchor as well as transparency and accountability. We conclude with a critical appraisal of the current ECB strategy.
