Related Variety, Unrelated Variety and Regional Functions: Identifying Sources of Regional Employment Growth in Germany from 2003 to 2008
Matthias Brachert, Alexander Kubis, Mirko Titze
Abstract
This article analyses how regional employment growth in Germany is affected by related variety, unrelated variety and the functions a region performs in the production process. Following the related variety literature, we argue that regions benefit from the existence of related activities that facilitate economic development. However, we argue that the sole reliance of related variety on standard industrial classifications remains debatable. Hence, we offer estimations for establishing that conceptual progress can indeed be made when a focus for analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety. Our findings suggest that related variety only in combination with a high functional specialization of the region facilitates regional growth in Germany. Additionally, also unrelated variety per se fails to wield influences affecting development of regions. It is rather unrelated, but functionally proximate variety in the groups “White Collar” and “Blue Collar Workers” positively affects regional employment growth.

International Fragmentation of Production and the Labour Input into Germany’s Exports – An Input-Output-analysis
Hans-Ulrich Brautzsch, Udo Ludwig
IWH Discussion Papers,
No. 14,
2011
Abstract
The import penetration of exports has become a topic of public debate, particularly in the context of Germany’s position as one of the world’s leading exporters. The growth in the volume of intermediate products purchased from abroad for subsequent processing into export goods in Germany seems to be undermining the importance of exports as a driver of domestic production and employment. The gains that arise from an increase in exports seem to have been offset by the losses caused by the crowding out of local production by imports. Empirical evidence on the impact of this international integration of the goods market on the German labour market is ambiguous. Short-term negative effects on employment are claimed to be offset by the long-term benefit that the jobs lost in the short run will eventually be replaced by higher-skilled jobs with better
perspectives. Against this background, the following hypothesis is tested empirically: Germany is poor in natural resources, but rich in skilled labour. In line with the Heckscher- Ohlin theory, Germany should therefore specialize in the production of export goods and services that are relatively intensive in these factors and should import those goods and services that are relatively intensive in unskilled labour. The empirical part of the paper deals with the extent of the German export penetration by imports. At first, it analyses by what ways imports are affecting the exports directly and indirectly and shows the consequences of import penetration of exports for the national output and employment. Secondly, consequences for employment are split in different skill types of labour. These issues are discussed with the standard open static inputoutput- model. The data base is a time series of official input-output tables. The employment effects for Germany divided by skill types of labour are investigated using skill matrices generated by the authors.

Bank-specific Shocks and the Real Economy
Claudia M. Buch, Katja Neugebauer
Journal of Banking and Finance,
No. 8,
2011
Abstract
Governments often justify interventions into the financial system in the form of bail outs or liquidity assistance with the systemic importance of large banks for the real economy. In this paper, we analyze whether idiosyncratic shocks to loan growth at large banks have effects on real GDP growth. We employ a measure of idiosyncratic shocks which follows Gabaix (forthcoming). He shows that idiosyncratic shocks to large firms have an impact on US GDP growth. In an application to the banking sector, we find evidence that changes in lending by large banks have a significant short-run impact on GDP growth. Episodes of negative loan growth rates and the Eastern European countries in our sample drive these results.

Upturn in Saxony-Anhalt in between structural Barriers

Wirtschaft im Wandel,
No. 7,

Abstract
Anders als in der Wirtschaftskrise hat der Unternehmenssektor im Jahr 2010 seine tragende Rolle für Wachstum und Beschäftigung in Sachsen-Anhalt zurückgewonnen. Die Unternehmen haben ihre Wettbewerbsposition gefestigt: Die Produktivität ist gestiegen, Arbeitsstunden und Beschäftigung wurden aufgestockt. Das Bruttoinlandsprodukt (BIP) erhöhte sich im Jahr 2010 um 2,4% und damit stärker als im Durchschnitt der ostdeutschen Flächenländer. Es wird im Jahr 2011 um 2,6% steigen. Der Produktionsausfall in der Industrie während der Krise konnte bis auf 6% bereits wieder wettgemacht werden. Trotz des für Ostdeutschland überdurchschnittlichen Produktionswachstums blieb Sachsen-Anhalt bei der Pro-Kopf-Produktion unter dem ostdeutschen Durchschnitt. Bei der Erwerbstätigenproduktivität gehört das Land jedoch zu den Spitzenreitern, auch wenn das Vorkrisenniveau noch nicht wieder erreicht wurde.

Part-time Jobs Again Determine Working Time
Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 6,
2011
Abstract
Während der schweren Wirtschaftskrise im Jahr 2009 wurde vor allem durch Arbeitszeitverkürzungen ein drastischer Beschäftigungseinbruch verhindert. Dafür waren zwei Prozesse maßgebend: Zum einen wurde der Verlust von Vollzeitstellen durch die Ausweitung von Teilzeitstellen kompensiert. Zum anderen wurde die tatsächlich geleistete Arbeitszeit je Erwerbstätigen durch Kurzarbeit, den Abbau von Überstunden und das Abschmelzen der Arbeitszeitkonten reduziert. Infolge des konjunkturellen Aufschwunges stieg die geleistete Arbeitszeit je Erwerbstätigen deutlich an und hat inzwischen fast den Vorkrisenstand erreicht. Dies ist darauf zurückzuführen, dass sich die konjunkturell reagibelsten Komponenten der Arbeitszeit – Kurzarbeit, bezahlte Überstunden und Arbeitszeitkonteneffekte – ihren „normalen“ Mustern angenähert haben. Die Entwicklung der geleisteten Arbeitszeit je Erwerbstätigen liegt im Niveau nunmehr wieder auf ihrem Trend. Der entscheidende Prozess, der diesen Trend bestimmt, ist die anhaltende Ausweitung der Teilzeitbeschäftigung zu Lasten der Vollzeitbeschäftigung.

Are Qualitative Inflation Expectations Useful to Predict Inflation?
Rolf Scheufele
Journal of Business Cycle Measurement and Analysis,
No. 1,
2011
Abstract
This paper examines the properties of qualitative inflation expectations collected from economic experts for Germany. It describes their characteristics relating to rationality and Granger causality. An out-of-sample simulation study investigates whether this indicator is suitable for inflation forecasting. Results from other standard forecasting models are considered and compared with models employing survey measures. We find that a model using survey expectations outperforms most of the competing models. Moreover, we find some evidence that the survey indicator already contains information from other model types (e. g. Phillips curve models). However, the forecast quality may be further improved by completely taking into account information from some financial indicators.

Incubating an Illusion? Long-term Incubator Firm Performance after Graduation
Michael Schwartz
Growth and Change,
No. 4,
2011
Abstract
Local economic development policies worldwide perceive business incubation as an effective measure to promote regional growth through the support of young and innovative ventures. The common assumption is that incubation promotes firm growth, in particular after these firms graduated from their incubator organizations. This article investigates the long-term performance of 324 graduate firms from five German business incubators (incubated between 1990 and 2006) after they have (successfully) completed their incubation. The present study does not suffer from a survivor bias, meaning that performance data of non-surviving firms is also included. Using employment and sales measures as performance indicators, this study contributes to our knowledge with regard to long-term incubator firm performance after graduation. While in the first years after graduation there is significant growth of formerly incubated firms, further results do not support the presumption of continuous firm growth beyond incubation. A minority of graduate firms exhibits a strong increase in performance, but the majority of firms do not experience considerable growth.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
North American Journal of Economics and Finance,
No. 3,
2011
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation, we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

On the Institutional Safeguarding of Monetary Policy – a Post-Keynesian Perspective
A. Heise, Toralf Pusch
International Journal of Public Policy,
No. 1,
2011
Abstract
The paper takes a fresh look at the governance of the most important macroeconomic objectives: price stability and full employment. On the basis of a post-Keynesian market constellations approach, the necessity and institutional requirements of the coordination of macroeconomic policy areas in general and an optimal central bank setting in particular are analysed, and an amelioration of monetary policy of the neo-Keynesian ‘new macroeconomic consensus’ is provided.
