Abstract
Starting from well-known empirical stylized facts of financial time series, we develop dynamic portfolio protection trading strategies based on econometric methods. As a criterion for riskiness, we consider the evolution of the value-at-risk spread from a GARCH model with normal innovations relative to a GARCH model with generalized innovations. These generalized innovations may for example follow a Student t, a generalized hyperbolic, an alpha-stable or a Generalized Pareto distribution (GPD). Our results indicate that the GPD distribution provides the strongest signals for avoiding tail risks. This is not surprising as the GPD distribution arises as a limit of tail behaviour in extreme value theory and therefore is especially suited to deal with tail risks. Out-of-sample backtests on 11 years of DAX futures data, indicate that the dynamic tail-risk protection strategy effectively reduces the tail risk while outperforming traditional portfolio protection strategies. The results are further validated by calculating the statistical significance of the results obtained using bootstrap methods. A number of robustness tests including application to other assets further underline the effectiveness of the strategy. Finally, by empirically testing for second-order stochastic dominance, we find that risk averse investors would be willing to pay a positive premium to move from a static buy-and-hold investment in the DAX future to the tail-risk protection strategy.

No Sign of Price Distortions – Lack of Evidence for Effects of US Bank Bailouts
There has been much political and public controversy surrounding the very large rescue packages offered to the banking sector in the course of the financial crisis of 2007 to 2009. The aim of the packages was to stabilise the financial sector and, therefore, the development of the real economy. The downsides of these bailouts were the enormous financial cost to the taxpayer, increased assumption of risk by the government and possible distortive effects on competition in the banking market – since not all banks were given financial support. Researchers at the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association led by Professor Felix Noth have now studied the long-term, indirect and possible market-distorting effects of the US rescue packages.

The Perception of Financial Inferiority Nurtures Negative Attitudes Towards Foreigners
When people feel that their own economic status is inferior to the economic status of a relevant peer group, it becomes more likely that they develop negative attitudes towards foreigners. This link was found in a new study of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association. The effect is particularly strong with respect to foreigners from low-wage countries.

Exporting Liquidity: Branch Banking and Financial Integration
Erik P. Gilje, Elena Loutskina, Philip E. Strahan
Journal of Finance,
No. 3,
2016
Abstract
Using exogenous liquidity windfalls from oil and natural gas shale discoveries, we demonstrate that bank branch networks help integrate U.S. lending markets. Banks exposed to shale booms enjoy liquidity inflows, which increase their capacity to originate and hold new loans. Exposed banks increase mortgage lending in nonboom counties, but only where they have branches and only for hard‐to‐securitize mortgages. Our findings suggest that contracting frictions limit the ability of arm's length finance to integrate credit markets fully. Branch networks continue to play an important role in financial integration, despite the development of securitization markets.

Foreign Direct Investment: The Role of Institutional and Cultural Determinants
Stefan Eichler, N. Lucke
Applied Economics,
No. 11,
2016
Abstract
Using panel data for 29 source and 65 host countries in the period 1995–2009, we examine the determinants of bilateral FDI stocks, focusing on institutional and cultural factors. The results reveal that institutional and cultural distance is important and that FDI has a predominantly regional aspect. FDI to developing countries is positively affected by better institutions in the host country, while foreign investors prefer to invest in developed countries that are more corrupt and politically unstable compared to home. The results indicate that foreign investors prefer to invest in countries with less diverse societies than their own.

Assessing European Competitiveness: The New CompNet Microbased Database
Paloma Lopez-Garcia, Filippo di Mauro
ECB Working Paper,
No. 1764,
2015
Abstract
Drawing from confidential firm-level balance sheets for 17 European countries (13 Euro-Area), the paper documents the newly expanded database of cross-country comparable competitiveness-related indicators built by the Competitiveness Research Network (CompNet). The new database provides information on the distribution of labour productivity, TFP, ULC or size of firms in detailed 2-digit industries but also within broad macrosectors or considering the full economy. Most importantly, the expanded database includes detailed information on critical determinants of competitiveness such as the financial position of the firm, its exporting intensity, employment creation or price-cost margins. Both the distribution of all those variables, within each industry, but also their joint analysis with the productivity of the firm provides critical insights to both policy-makers and researchers regarding aggregate trends dynamics. The current database comprises 17 EU countries, with information for 56 industries, including both manufacturing and services, over the period 1995-2012. The paper aims at analysing the structure and characteristics of this novel database, pointing out a number of results that are relevant to study productivity developments and its drivers. For instance, by using covariances between productivity and employment the paper shows that the drop in employment which occurred during the recent crisis appears to have had “cleansing effects” on EU economies, as it seems to have accelerated resource reallocation towards the most productive firms, particularly in economies under stress. Lastly, this paper will be complemented by four forthcoming papers, each providing an in-depth description and methodological overview of each of the main groups of CompNet indicators (financial, trade-related, product and labour market).

Cross-border Interbank Networks, Banking Risk and Contagion
Lena Tonzer
Journal of Financial Stability,
2015
Abstract
Recent events have highlighted the role of cross-border linkages between banking systems in transmitting local developments across national borders. This paper analyzes whether international linkages in interbank markets affect the stability of interconnected banking systems and channel financial distress within a network consisting of banking systems of the main advanced countries for the period 1994–2012. Methodologically, I use a spatial modeling approach to test for spillovers in cross-border interbank markets. The results suggest that foreign exposures in banking play a significant role in channeling banking risk: I find that countries that are linked through foreign borrowing or lending positions to more stable banking systems abroad are significantly affected by positive spillover effects. From a policy point of view, this implies that in stable times, linkages in the banking system can be beneficial, while they have to be taken with caution in times of financial turmoil affecting the whole system.

Risk and Return - Is there an Unholy Cycle of Ratings and Yields?
Makram El-Shagi, Gregor von Schweinitz
Economics Letters,
2015
Abstract
After every major financial crisis, the question about the responsibility of the rating agencies resurfaces. Regarding government bonds, the most frequently voiced concern targeted “unreasonably” bad ratings that might trigger capital flights and increasing risk premia which sanction further rating downgrades. In this paper we develop a multivariate, nonparametric version of the Pesaran type cointegration model that allows for nonlinearities, to show that a unique equilibrium between ratings and sovereign yields exists. Therefore, we have to reject the concern that there is an unholy cycle leading to certain default in the long run.

Coordination between Municipalities and Local Non-Municipal Public Units (NMPUs) for Supporting Urban Economic Development: Theoretical Analysis and Empirical Evidence for the Example of Universities in Germany

Koordination raumwirksamer Politik: Mehr Effizienz und Wirksamkeit von Politik durch abgestimmte Arbeitsteilung,
2015
Abstract
In zahlreichen europäischen Städten gibt es Versuche, der lokalen Wirtschaftsentwicklung eine neue Richtung zu geben, u.a. durch die Ansiedlung von Nicht-Kommunalen Öffentlichen Einrichtungen (NKOE), z.B. Bundesagenturen, Gerichte, Rechnungshöfe, Landesmuseen oder Universitäten. Allerdings liegen die Kompetenzen für solche NKOE nicht bei den Kommunen, sondern zumeist bei den höheren staatlichen Ebenen. Deshalb haben die Kommunen keinen unmittelbaren Einfluss auf die Ansiedlung von NKOE. Sobald aber eine entsprechende Entscheidung gefallen ist, können die Kommunen die weitere Entwicklung von NKOE begünstigen. Im Beitrag wird zunächst eine Kategorisierung von NKOE durchgeführt, und zwar sowohl gemäß der Bedeutung von NKOE für die lokale Wirtschaftsentwicklung als auch hinsichtlich des Einflusses lokaler Maßnahmen auf die Leistungsfähigkeit von NKOE. Es wird gezeigt, dass Universitäten zu jener Kategorie von NKOE zählen, für die eine Koordination der eigenen Aktivitäten mit jenen der Kommunen besonders wichtig sein dürfte. Die Effekte von Universitäten für die lokale Wirtschaftsentwicklung wurden bereits vielfach diskutiert. Die Fähigkeit der Universitäten, das für ihre Effektivität erforderliche Humankapital zu attrahieren, hängt von verschiedenen lokalen Faktoren ab. Folglich gibt es eine reziproke Beziehung zwischen Kommunen und Universitäten. Eine Koordinierung der jeweiligen Aktivitäten wäre deshalb für beide Seiten von Vorteil. Dies gilt z.B. für den Bereich der Informationspolitik. Eine Kommune sollte nach innen wie nach außen die Vorzüge der örtlichen Universitäten kommunizieren; umgekehrt sollte auch eine Universität die Stärken des lokalen Umfelds deutlich machen. Da für den Bereich der Informationspolitik empirische Daten leicht zugänglich sind, konzentriert sich der empirische Teil des Beitrags auf eine empirische Untersuchung der Internetpräsentationen ausgewählter Städte und Universitäten. Es zeigt sich, dass in den meisten betrachteten Städten die Koordinierung zwischen Kommunen und Universitäten zu wünschen übrig lässt. Eine Verbesserung dieser Situation ließe sich z.B. durch die Einführung
finanzieller Anreizmechanismen erreichen.

Do We Need New Modelling Approaches in Macroeconomics?
Claudia M. Buch, Oliver Holtemöller
Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.
