Censored Fractional Response Model: Estimating Heterogeneous Relative Risk Aversion of European Households

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.

Germany Benefited Substantially from the Greek Crisis
The balanced budget in Germany is largely the result of lower interest payments due to the European debt crisis. Research from the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows that the debt crisis resulted in a reduction in German bund rates of about 300 basis points (BP), yielding interest savings of more than EUR 100 billion (or more than 3% of gross domestic product, GDP) during the period 2010 to 2015. A significant part of this reduction is directly attributable to the Greek crisis. When discussing the costs to the German tax payer of saving Greece, these benefits should not be overlooked, as they tend to be larger than the expenses, even in a scenario where Greece does not repay any of its debts.

Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
L. Cycon, Michael Koetter
IWH Discussion Papers,
No. 9,
2015
Abstract
With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.

The Age of Global Value Chains: Maps and Policy Issues
Joao Amador, Filippo di Mauro
CEPR Press,
2015
Abstract
Global value chains (GVCs) - referring to the cross-border flows of goods, investment, services, know-how and people associated with international production networks - have transformed the world. Their emergence has resulted in a complete reconfiguration of world trade, bearing a strong impact on the assessment of competitiveness and economic policy. The contributions to this eBook are based on research carried out within the scope of the Eurosystem Competitiveness Research Network (CompNet), bringing together participants from EU national central banks, universities and international organisations interested in competitiveness issues. The mapping of GVCs and full awareness about their implications are essential to informed public debate and improved economic policy.

Rejection of Reforms as a Chance for Reforms
The President of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association continues to see a chance for an agreement between the European Union (EU) and Greece. On the surface, Grexit looks now more likely than ever. But the resignation of Yanis Varoufakis, Minister of Finance, and the outcome of the referendum may also provide a chance for the Greek government to agree on reforms and save face. But the window of opportunity is closing very fast.

Der Europäische Gerichtshof und der Grexit

Wirtschaft im Wandel,
No. 3,
2015
Abstract
Die Europäische Zentralbank hat vom Europäischen Gerichtshof (EuGH) grünes Licht für den Ankauf von Staatsanleihen bekommen. Wie der EuGH ent-schied, dürfen die Zentralbanker unter Einhaltung bestimmter Bedingungen Staatsanleihen der Euroländer aufkaufen. Die Richter billigen damit ein Programm, das auf eine Entscheidung des EZB-Rats im September 2012 zurückgeht: Die Notenbank werde notfalls unbegrenzt Staatsanleihen von Euroländern kaufen, um die Währung zu stützen, hatte damals EZB-Präsident Mario Draghi verkündet. Allerdings darf die Zentralbank nur tätig werden, wenn das betroffene Land bestimmten Qualitätsansprüchen genügt oder unter den Euro-Rettungsschirm geschlüpft ist und folglich strenge Reformvorgaben erfüllen muss. Die Richter argumentieren, dass das Programm die währungspolitischen Befugnisse der EZB nicht überschreite. Es verstoße nicht gegen das Verbot der monetären Finanzierung von Mitgliedstaaten, sondern es handele sich dabei um ein Programm, das dem Bereich der Währungspolitik zuzuordnen sei und zu dem Ziel der EZB beitrage, die Preisstabilität in den Mitgliedstaaten zu gewährleisten. Die Entscheidung gibt der EZB auch Rückendeckung beim aktuell laufenden Anleihekaufprogramm (quantitative easing) vom Frühjahr dieses Jahres. Dieses hat zum Ziel, bis Ende September 2016 Staatsanleihen und Anleihen anderer staatlicher Einheiten aller Eurostaaten im Wert von bis zu einer Billion Euro anzukaufen. Damit soll Deflations-tendenzen entgegengewirkt werden.

Kommentar: Manövriert sich die EZB in eine Falle?
Reint E. Gropp
Wirtschaft im Wandel,
No. 1,
2015
Abstract
Die EZB hat am 22. Januar 2015 beschlossen, in großem Umfang Anleihen öffentlicher Institutionen aus dem Euroraum, darunter auch der Nationalstaaten, zu kaufen. Es gibt gute Gründe für diese Maßnahme: Marktbasierte mittelfristige Inflationserwartungen sind zuletzt deutlich gesunken, die Inflationsrate ist tendenziell rückläufig und war zuletzt sogar negativ. Die Wahrscheinlichkeit einer deflationären Spirale hat sich erhöht, mit unabsehbaren Folgen für die wirtschaftliche Entwicklung. Die schwache Verbraucherpreisentwicklung im Euroraum basiert auf mehreren Faktoren: der schleppenden Konjunkturentwicklung, fallenden Ölpreisen und fiskalpolitischer Konsolidierung in einigen Euroländern (Spanien, Portugal, Irland).

Switching to Exchange Rate Flexibility? The Case of Central and Eastern European Inflation Targeters
Andrej Drygalla
FIW Working Paper, Nr. 139,
No. 139,
2015
Abstract
This paper analyzes changes in the monetary policy in the Czech Republic, Hungary, and Poland following the policy shift from exchange rate targeting to inflation targeting around the turn of the millennium. Applying a Markovswitching dynamic stochastic general equilibrium model, switches in the policy parameters and the volatilities of shocks hitting the economies are estimated and quantified. Results indicate the presence of regimes of weak and strong responses of the central banks to exchange rate movements as well as periods of high and low volatility. Whereas all three economies switched to a less volatile regime over time, findings on changes in the policy parameters reveal a lower reaction to exchange rate movements in the Czech Republic and Poland, but an increased attention to it in Hungary. Simulations for the Czech Republic and Poland also suggest their respective central banks, rather than a sound macroeconomic environment, being accountable for reducing volatility in variables like inflation and output. In Hungary, their favorable developments can be attributed to a larger extent to the reduction in the size of external disturbances.

Financial Stability and Central Bank Governance
Michael Koetter, Kasper Roszbach, G. Spagnolo
International Journal of Central Banking,
No. 4,
2014
Abstract
The financial crisis has ignited a debate about the appropriate objectives and the governance structure of Central Banks. We use novel survey data to investigate the relation between these traits and banking system stability focusing in particular on their role in micro-prudential supervision. We find that the separation of powers between single and multiple bank supervisors cannot explain credit risk prior or during the financial crisis. Similarly, a large number of Central Bank governance traits do not correlate with system fragility. Only the objective of currency stability exhibits a significant relation with non-performing loan levels in the run-up to the crisis. This effect is amplified for those countries with most frequent exposure to IMF missions in the past. Our results suggest that the current policy discussion whether to centralize prudential supervision under the Central Bank and the ensuing institutional changes some countries are enacting may not produce the improvements authorities are aiming at. Whether other potential improvements in prudential supervision due to, for example, external disciplinary devices, such as IMF conditional lending schemes, are better suited to increase financial stability requires further research.
