Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

Macroeconomic Policy Formation in Africa - General Issues
Karl Wohlmuth, Achim Gutowski, M. Kandil, Tobias Knedlik, O. O. Uzor
African Development Perspectives Yearbook, Vol. 16,
2014
Abstract
In Volume 16 with the title “Macroeconomic Policy Formation in Africa - General Issues“ new macroeconomic policy frameworks for Africa are discussed. Emphasis is on macroeconomic policies focusing on sustainable and inclusive growth, especially by considering the employment targeting of macroeconomic policy frameworks in Africa. The responses of the macroeconomic policymakers in Africa to the Euro crisis and to the recent globalization trends are reviewed and analyzed. The role of macroeconomic policies for generating sustainable and inclusive growth is also discussed. In Volume 16 also the economics of the “Arab Spring“ countries is analyzed, by focusing on the socioeconomic conditions and the economic policy factors that have led to the “Arab Spring“ events. Highlighted are the cases of Egypt and Tunisia, and the new strategic and policy frameworks in these countries after the democratic changes. An agenda for comprehensive policy reforms for the Arab countries in Africa is presented. In forthcoming Volume 17 with the title “Macroeconomic Policy Formation in Africa - Country Cases“ macroeconomic policies in African post-conflict countries and in the ECOWAS region are considered. Volume 17 contains also a section with Book Reviews and Book Notes.

Political Institutionalisation and Economic Specialisation in Polycentric Metropolitan Regions – The Case of the East-German ‘Saxony Triangle’
Peter Franz, Christoph Hornych
IWH Discussion Papers,
Nr. 6,
2009
Abstract
The rising attention of politicians as well as scientists in the EU to the large urban agglomerations as centres of economic growth is accompanied by political efforts to identify and to demarcate such agglomerations under the label ‘metropolitan regions’. This study develops a theoretical framework broaching the issue of cooperation between municipalities from the perspective of regional economics as well as political science. The framework is applied to the empirical case of the polycentric metropolitan region ‘Saxony Triangle’ in East Germany. The results show that various intervening factors prevent intense cooperation between the actors in the region. Policy implications and con-
clusions for future research are discussed.

Industry Concentration and Regional Innovative Performance – Empirical Evidence for Eastern Germany
Christoph Hornych, Michael Schwartz
Post-Communist Economies,
2009
Abstract
Regarding technological innovativeness, the transformed economy of the former German Democratic Republic (GDR) clearly lags behind the western part of the country. To face this weakness a broad mixture of policy measures was carried out in recent years. Particular attention is drawn to the development of industry concentrations and economic ‘clusters’. However, little is known about the effectiveness of these policy measures regarding how industry concentrations in fact promote innovative performance in Eastern Germany. The present study tries to fill this gap by analysing the relationship between industry concentration in Eastern Germany and regional innovative performance. Our empirical analysis is based upon the number of patent applications of 22 manufacturing industries in 22 Eastern German planning regions. The estimated regression models indicate an inverted-U relationship between the degree of industry concentration and innovative performance. An exceedingly high degree of industry concentration in one region hampers regional innovative output. We discuss policy implications of our findings and give recommendations for future refinement of ‘cluster’-supporting policy schemes in Eastern Germany.

The present study tries to fill this gap by analyzing the relationship between industry concentration in Eastern Germany and regional innovative performance. Our empirical analysis is based upon the number of patent applications of 22 manufacturing industries in 22 Eastern German planning regions. The estimated regression models indicate an inverted U-shaped relationship between the degree of industry concentration and innovative performance. An exceedingly high degree of industry concentration in one region hampers regional innovative output. We discuss policy implications of our findings and give recommendations for future refinement of ‘cluster’-supporting policy schemes in Eastern Germany.

Vierteljährliche Konjunkturberichterstattung für das Land Sachsen-Anhalt - Die gesamtwirtschaftliche Lage im 1. Quartal 2014 -
Brigitte Loose, Hans-Ulrich Brautzsch, Franziska Exß
IWH Online,
Nr. 4,
2014
Abstract
Die gesamtwirtschaftliche Produktion in Sachsen-Anhalt ist nach den indikatorgestützten Schätzungen zum Jahresanfang 2014 mit einer Rate von 0,8% ähnlich kräftig gestiegen wie in Deutschland insgesamt (0,7%). Allerdings setzt sich in Deutschland der Aufschwung nun bereits das vierte Quartal in Folge fort, während dieser in Sachsen-Anhalt zum Jahresende 2013 aufgrund einer rückläufigen Entwicklung in der Industrie und einer stagnierenden Bruttowertschöpfung im Dienstleistungsbereich zwischenzeitlich unterbrochen war. Auch im Vorjahresvergleich hat die Wirtschaft in Sachsen-Anhalt deutlich zugelegt. Die gesamtwirtschaftliche Produktion stieg gegenüber dem ersten Quartal 2013 um 1,8%, in Deutschland insgesamt nahm sie um 2,5% zu (vgl. Abbildung 1). Insbesondere das Verarbeitende Gewerbe konnte nach der Schwäche zum Jahresausklang 2013 nun wieder zulegen (vgl. saisonbereinigte Vorquartalsvergleiche in Tabelle 1). Die Bruttowertschöpfung dürfte hier sogar stärker gestiegen sein als in Deutschland. Vom Sog der vor allem binnenwirtschaftlich getriebenen Erholung in Deutschland profitierten zeitlich verzögert nun auch die Vorleistungs- sowie die Investitionsgüterproduzenten in Sachsen-Anhalt.

The Regional Distribution of Foreign Investment in Russia: Are Russians more Appealing to Multinationals as Consumers or as Natural Resource Holders?
K. Gonchar, Philipp Marek
Economics of Transition and Institutional Change,
Nr. 4,
2014
Abstract
This article conducts a plant-level study of the factors affecting foreign direct investment (FDI) inflow to a large opening economy endowed with specific factor advantages. We conclude that the distribution of FDI in Russian regions depends on market access and can be most notably described by the knowledge-capital framework. Factor endowments built by natural resources are more successful in explaining the location decisions of export–platform affiliates. The impact of natural resources depends on how the availability of these resources is measured. The results reject the crowding out effects of resource FDI and prove co-location mode, when service investments are attracted to resource-rich regions. Labour cost advantages better explain the preferences of non-trading service affiliates.

Socially Gainful Gender Quotas
Walter Hyll, Oded Stark
Journal of Economic Behavior and Organization,
Nr. 105,
2014
Abstract
We study the impact of gender quotas on the acquisition of human capital. We assume that individuals’ formation of human capital is influenced by the prospect of landing high-pay top positions, and that these positions are regulated by gender-specific quotas. In the absence of quotas, women consider their chances of getting top positions to be lower than men’s. The lure of top positions induces even men of relatively low ability to engage in human capital formation, whereas women of relatively high ability do not expect to get top positions and do not therefore engage in human capital formation. Gender quotas discourage men who are less efficient in forming human capital, and encourage women who are more efficient in forming human capital. We provide a condition under which the net result of the institution of gender quotas is an increase in human capital in the economy as a whole.

Changing Forces of Gravity: How the Crisis Affected International Banking
Claudia M. Buch, Katja Neugebauer, Christoph Schröder
ZEW Discussion Paper, No. 14-006,
2014
Abstract
The global financial crisis has brought to an end a rather unprecedented period of banks’ international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years 2002-2011, we study bank internationalization before and during the crisis. Our data allow analyzing not only the international assets of the banks’ headquarters but also of their foreign affiliates. We show that banks have lowered their international assets, both along the extensive and the intensive margin. This withdrawal from foreign markets is the result of changing market conditions, of policy interventions, and of a weakly increasing sensitivity of banks to financial frictions.

Musterknabe Osteuropa: Subventionskontrolle und staatliche Beihilfen
Jens Hölscher
Wirtschaftsdienst,
Nr. 5,
2014
Abstract
Am 1.5.2004 sind zehn neue Mitgliedstaaten, vor allem Transformationsländer, in die EU aufgenommen worden. Drei Jahre später, am 1.1.2007, kamen Bulgarien und Rumänien hinzu. Während deutsche Unternehmer zunächst die zusätzliche Konkurrenz fürchteten, bewerten sie die Auswirkungen der Osterweiterung inzwischen positiv. Die neuen Mitgliedstaaten haben von ihrem Beitritt grundsätzlich profitiert, sogar in Hinblick auf die Beihilferegelungen konnten sie den strengen Anforderungen der EU entsprechen. Allerdings haben sich flexible Wechselkurse in der Krise für die Länder außerhalb des Euroraums als Vorteil erwiesen. Zudem leiden Rumänien und Bulgarien unter der Instabilität ihrer politischen Systeme.
