Abstract
Currency crises episodes of 1996, 1998, and 2001 are used to identify common country specific causes of currency crises in South Africa. The paper identifies crises by the use of an Exchange Market Pressure (EMP) index as introduced by Eichengreen, Rose and Wyplosz (1996). It extends the Signals Approach introduced by Kaminsky and Reinhart (1996, 1998) by developing a composite indicator in order to measure the evolution of currency crisis risk in South Africa. The analysis considers the standard suspects from international currency crises and country specifics as identified by the Myburgh Commission (2002) and current literature as potentially relevant indicators.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
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,
No. 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.

Warum exportiert der Osten so wenig? Eine empirische Analyse der Exportaktivitäten deutscher Bundesländer
Götz Zeddies
AStA - Wirtschafts- und Sozialstatistisches Archiv,
No. 4,
2009
Abstract
In the aftermath of re-unification, East German exports declined around 70% due to the breakdown of COMECON trade. Although since the mid-1990s export growth rates of the New Federal States were higher than those of their West German counterparts, export performance of East German States measured by the share of exports in GDP is still comparatively poor. Whereas for a long time the low export performance of East German producers was ascribed to competitive disadvantages, in the meantime structural deficits on the micro and/or macro level are often considered as the main reason. Using bilateral trade data of German Federal States, the present paper shows on the basis of an orthodox gravity model of trade that East German exports are explicitly lower than predicted by the model. But if the gravity model is augmented by additional variables representing structural differences between Federal States, the latter explain almost entirely the lower export performance of Eastern Germany. Thus, especially the smaller firm sizes and the lower shares of manufacturing industries in gross value added are identified as important explanatory factors of the comparatively weak export performance of the New German States.

Drivers of the Spatial Emergence and Clustering of the Photovoltaic Industry in Germany

Zeitschrift für Wirtschaftsgeographie,
No. 3,
2015
Abstract
The drivers of the spatial emergence and clustering of the photovoltaic industry in Germany. Following the relatedness literature, we explore to what extent related industries influenced the regional emergence of the photovoltaic (PV) industry. In addition, we shed light on factors explaining selective processes of clustering. We particularly argue that generic resources and resources of related activities have been crucial for the regional concentration in early phases of the industry life cycle. With increasing maturity, industry-specific resources became more important. Based on a unique dataset containing population dynamics of the German PV industry, the hypotheses are tested empirically. Our results partially confirm the assumed beneficial effects of related industries for the emergence of the PV industry. Moreover, we observe changes in the relative importance of factors supporting regional concentration, with industry-specific resources becoming dominant as the industry matures.

Zur wirtschaftlichen Lage Ostdeutschlands 25 Jahre nach dem Mauerfall
Oliver Holtemöller
TOP Magazin Halle,
No. 4,
2014
Abstract
Wanderten in den vergangenen 25 Jahren zahlreiche Menschen aus Ostdeutschland ab, so ist dieser Trend per saldo jüngst zum Erliegen gekommen. Dies hat auch damit zu tun, dass sich die Arbeitsmarktperspektiven verbessert haben. Die durchschnittlichen Bruttomonatsverdienste der Vollzeitbeschäftigten liegen in Ostdeutschland jedoch erst bei etwa 70 Prozent der Verdienste im Westen. Die wirtschaftlichen Möglichkeiten der Menschen in Ostdeutschland liegen aber viel näher am westdeutschen Niveau. So betragen die verfügbaren Einkommen im Osten immerhin 84 Prozent in Relation zum Westen. Berücksichtigt man noch Unterschiede der Preisniveaus, so kommt man auf ein reales Konsumniveau im Osten, das bei etwa 90 Prozent des Westniveaus liegt. Nach dem amerikanischen Bürgerkrieg war die Lücke zwischen der Produktion je Einwohner in den Nord- und den Südstaaten etwa so groß wie vor 25 Jahren zwischen Ost- und Westdeutschland; in den USA hat es aber 100 Jahre gedauert, bis sich die Lücke bis auf 10 Prozent geschlossen hatte. Auch verglichen mit anderen Transformationsländern wie beispielsweise Tschechien oder Polen ist der Aufholprozess Ostdeutschland deutlich weiter.
