Comment: IWH President Reint E. Gropp: ECB resists its critics and maintains its asset purchase programme. Leaving the option for a further extension is completely reasonable.
Some observers, including recently a number of major banks, are criticising the European Central Bank (ECB) for maintaining its asset purchase program, currently scheduled to run until March of 2017 and leaving the option open to extend it further.

Monetary-fiscal Policy Interaction and Fiscal Inflation: A Tale of Three Countries
Martin Kliem, Alexander Kriwoluzky, Samad Sarferaz
European Economic Review,
2016
Abstract
We study the impact of the interaction between fiscal and monetary policy on the low-frequency relationship between the fiscal stance and inflation using cross-country data from 1965 to 1999. In a first step, we contrast the monetary–fiscal narrative for Germany, the U.S., and Italy with evidence obtained from simple regression models and a time-varying VAR. We find that the low-frequency relationship between the fiscal stance and inflation is low during periods of an independent central bank and responsible fiscal policy and more pronounced in times of non-responsible fiscal policy and accommodative monetary authorities. In a second step, we use an estimated DSGE model to interpret the low-frequency measure structurally and to illustrate the mechanisms through which fiscal actions affect inflation in the long run. The findings from the DSGE model suggest that switches in the monetary–fiscal policy interaction and accompanying variations in the propagation of structural shocks can well account for changes in the low-frequency relationship between the fiscal stance and inflation.

Lend Global, Fund Local? Price and Funding Cost Margins in Multinational Banking
Rients Galema, Michael Koetter, C. Liesegang
Review of Finance,
No. 5,
2016
Abstract
In a proposed model of a multinational bank, interest margins determine local lending by foreign affiliates and the internal funding by parent banks. We exploit detailed parent-affiliate-level data of all German banks to empirically test our theoretical predictions in pre-crisis times. Local lending by affiliates depends negatively on price margins, the difference between lending and deposit rates in foreign markets. The effect of funding cost margins, the gap between local deposit rates faced by affiliates abroad and the funding costs of their parents, on internal capital market funding is positive but statistically weak. Interest margins are central to explain the interaction between internal capital markets and foreign affiliates lending.

German Federal Constitutional Court makes right decision on Draghis OMT programme
I welcome the decision by the German Federal Constitutional Court. The court approved OMT (outright monetary transactions), which enables the European Central Bank (ECB) to purchase short-term government bonds in secondary markets in order to stabilize euro member countries in a crisis.

Central Bank Transparency and Cross-border Banking
Stefan Eichler, Helge Littke, Lena Tonzer
Abstract
We analyze the effect of central bank transparency on cross-border bank activities. Based on a panel gravity model for cross-border bank claims for 21 home and 47 destination countries from 1998 to 2010, we find strong empirical evidence that a rise in central bank transparency in the destination country, on average, increases cross-border claims. Using interaction models, we find that the positive effect of central bank transparency on cross-border claims is only significant if the central bank is politically independent. Central bank transparency and credibility are thus considered complements by banks investing abroad.

Are Lacking Structural Reforms in the Financial Sector the Underlying Reason for the German Criticism of the ECB?
The major reason for the intense criticism of the European Central Bank’s (ECB’s) low-interest-rate policy may be the lack of structural reforms in the German banking system. The resulting persistent fragmentation increases the banking sector’s vulnerability to the low-interest-rate environment. Hence, parts of the banking sector, due to their strong ties to politicians, appear to have successfully influenced public opinion against the ECB.

Mere Criticism of the ECB is no Solution
M. Fratzscher, Reint E. Gropp, Jan Pieter Krahnen, Hans-Helmut Kotz, Christian Odendahl, Beatrice Weder di Mauro, Guntram Wolff
Einzelveröffentlichungen,
2016
Abstract
Die Kritik an der EZB in Deutschland ist kontraproduktiv. Die Geldpolitik muss expansiv bleiben, damit die EZB ihrem Mandat zumindest ansatzweise gerecht wird. Das gebietet auch der Erhalt ihrer Glaubwürdigkeit. Die EZB muss nicht weniger, sondern Europas Politik muss mehr tun. Sie muss entschiedener handeln, um Europa wieder auf einen Wachstumspfad zu bringen.
[Eine kürzere Version des Beitrags ist unter dem Titel “Kritik an Draghi ist noch keine Lösung“ erschienen in der Frankfurter Allgemeinen Sonntagszeitung vom 10 April 2016].
Die Politik, auch die deutsche, darf sich nicht länger ihrer Mitverantwortung für die gegenwärtige wirtschaftliche Lage in weiten Teilen Europas entziehen. Benötigt werden eine wachstumsfreundliche Fiskalpolitik, Strukturreformen zur Öffnung neuer Märkte und eine Konsolidierung und Restrukturierung des Finanzsektors. Dabei müssen vor allem wir in Deutschland uns den Spiegel vorhalten – denn die meisten dieser Reformen benötigen wir genauso dringend wie unsere europäischen Nachbarn.

“The German Saver” and the Low Policy Rate Environment
Reint E. Gropp, Vahid Saadi
IWH Online,
No. 9,
2015
Abstract
It is widely claimed that “the German saver” suffers (i.e. generates significantly lower returns on her savings) in the low interest environment that Germany currently experiences relative to a high interest rate environment. With “low interest rate environment”, the observers tend to mean “low policy rates”, i.e. the European Central Bank’s (ECB) main refinancing rate.

Censored Fractional Response Model: Estimating Heterogeneous Relative Risk Aversion of European Households
Qizhou Xiong
IWH Discussion Papers,
No. 11,
2015
Abstract
This paper estimates relative risk aversion using the observed shares of risky assets and characteristics of households from the Household Finance and Consumption Survey of the European Central Bank. Given that the risky share is a fractional response variable belonging to [0, 1], this paper proposes a censored fractional response estimation method using extremal quantiles to approximate the censoring thresholds. Considering that participation in risky asset markets is costly, I estimate both the heterogeneous relative risk aversion and participation cost using a working sample that includes both risky asset holders and non-risky asset holders by treating the zero risky share as the result of heterogeneous self-censoring. Estimation results show lower participation costs and higher relative risk aversion than what was previously estimated. The estimated median relative risk aversions of eight European countries range from 4.6 to 13.6. However, the results are sensitive to households’ perception of the risky asset market return and volatility.
