Abstract
Interactive regional learning involving various actors is considered a precondition for successful innovations and, hence, for regional development. Diasporas as non-native ethnic groups are regarded as beneficial since they enrich the creative class by broadening the cultural base and introducing new routines. Using data on research and development (R&D) collaboration projects, the analysis provides tentative evidence that the size of diasporas positively affects the region’s share of outward R&D linkages enabling the exchange of knowledge. The empirical analysis further confirms that these interactions mainly occur between regions hosting the same diasporas, pointing to a positive effect of ethnic proximity rather than ethnic diversity.

Effekte der Einführung des gesetzlichen Mindestlohns: Eine Fallstudie für das Handwerk in Sachsen-Anhalt
Hans-Ulrich Brautzsch, Birgit Schultz
Wirtschaft im Wandel,
No. 5,
2018
Abstract
Knapp 8% der Beschäftigten in den Handwerksbetrieben Sachsen-Anhalts verdienten vor der Einführung des gesetzlichen Mindestlohns zu Beginn des Jahres 2015 brutto weniger als 8,50 Euro je Stunde. Allerdings differiert die Betroffenheit stark. In den besonders betroffenen Gewerken war zu befürchten, dass die durch den Mindestlohn induzierte Kostensteigerung zu einem spürbaren Beschäftigungsabbau führt. In diesem Kontext werden drei Fragen untersucht: (1) Wie hoch war die Mindestlohnbetroffenheit im Handwerk in Sachsen-Anhalt? (2) Welche – über die Lohnkostenerhöhung hinausgehenden – Effekte hatte die Mindestlohneinführung in den Handwerksbetrieben? (3) Welche Ausweichreaktionen haben die Handwerksbetriebe unternommen, um die höhere Kostenbelastung zu bewältigen? Die Untersuchungen basieren auf den von den Handwerkskammern Halle und Magdeburg durchgeführten Konjunkturumfragen, die in Kooperation mit dem IWH um zusätzliche Fragen zur Mindestlohneinführung erweitert wurden. Die Ergebnisse der Schätzungen zeigen keine signifikanten Beschäftigungseffekte infolge der Einführung des gesetzlichen Mindestlohns. Vielmehr haben die Handwerksbetriebe vor allem mit Preiserhöhungen reagiert.

Auswirkungen des gesetzlichen Mindestlohns im Handwerk in Sachsen-Anhalt
Hans-Ulrich Brautzsch, Birgit Schultz
Zeitschrift für Wirtschaftspolitik,
No. 2,
2018
Abstract
This paper examines the effects of the minimum wage introduction in Germany in 2015 on the skilled crafts sector in Saxony-Anhalt.
Using novel survey data on the skilled crafts sector in Saxony-Anhalt, we examine three questions: (1) How many employees are affected by the minimum wage introduction in the skilled crafts sector in Saxony-Anhalt? (2) What are the effects of the minimum wage introduction? (3) How did firms react to wage increase?
We find that about 8 % of all employees in the skilled crafts sector in Saxony-Anhalt are directly affected by the minimum wage introduction. A difference-in-difference estimation reveals no significant employment effects of the minimum wage introduction. We test for alternative adjustment strategies and observe a significant increase of output prices.

The Economic Development of Saxony-Anhalt since 1990
Oliver Holtemöller, Axel Lindner
Abstract
This article describes the economic development of Saxony-Anhalt since 1990 in the context of the East German transition from a centrally planned economy to a market economy. In the early 1990s the economy of Saxony-Anhalt caught up quickly with West Germany, mainly because the capital stock was modernized and expanded. Convergence, however, has almost come to a halt for some time now and gross domestic product per employed person is still about 20% below the West German level. The challenge for economic policy is to further the catching-up process by fostering research and innovation and improving the skills of the workforce.

Abstract
This paper examines the effects of the minimum wage introduction in Germany in 2015 on the skilled crafts sector in Saxony-Anhalt. Using novel survey data on the skilled crafts sector in Saxony-Anhalt, we examine three questions: (1) How many employees are affected by the minimum wage introduction in the skilled crafts sector in Saxony- Anhalt? (2) What are the effects of the minimum wage introduction? (3) How have firms reacted to wage increase? We find that about 8% of all employees in the skilled crafts sector in Saxony-Anhalt are directly affected by the minimum wage introduction. A difference-in-difference estimation reveals no significant employment effects of the minimum wage introduction. We test for alternative adjustment strategies and observe a significant increase of output prices.

Pendlerströme führen zur regionalen Angleichung bei Beschäftigung
Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 4,
2017
Abstract
Im Jahr 2016 hatten 75% der erwerbsfähigen Personen, die in Ostdeutschland wohnten, dort auch einen Arbeitsplatz. In Westdeutschland waren es 81%. Berücksichtigt man den Pendlerüberschuss gegenüber Westdeutschland sowie die längeren Jahresarbeitszeiten in Ostdeutschland, verschwindet der Rückstand auf den Westen: Die erwerbsfähigen Ostdeutschen haben im Durchschnitt genauso viele Arbeitsstunden geleistet wie die Westdeutschen. Auch auf Kreisebene kann kein ausgeprägtes Ost-West-Gefälle ausgemacht werden. Vielmehr zeigen sich deutliche Disparitäten zwischen Süddeutschland (einschließlich Sachsens und Thüringens) und großen Teilen Norddeutschlands.

Complex-task Biased Technological Change and the Labor Market
Colin Caines, Florian Hoffmann, Gueorgui Kambourov
Review of Economic Dynamics,
April
2017
Abstract
In this paper we study the relationship between task complexity and the occupational wage- and employment structure. Complex tasks are defined as those requiring higher-order skills, such as the ability to abstract, solve problems, make decisions, or communicate effectively. We measure the task complexity of an occupation by performing Principal Component Analysis on a broad set of occupational descriptors in the Occupational Information Network (O*NET) data. We establish four main empirical facts for the U.S. over the 1980–2005 time period that are robust to the inclusion of a detailed set of controls, subsamples, and levels of aggregation: (1) There is a positive relationship across occupations between task complexity and wages and wage growth; (2) Conditional on task complexity, routine-intensity of an occupation is not a significant predictor of wage growth and wage levels; (3) Labor has reallocated from less complex to more complex occupations over time; (4) Within groups of occupations with similar task complexity labor has reallocated to non-routine occupations over time. We then formulate a model of Complex-Task Biased Technological Change with heterogeneous skills and show analytically that it can rationalize these facts. We conclude that workers in non-routine occupations with low ability of solving complex tasks are not shielded from the labor market effects of automatization.

Applied Economics Letters,
No. 7,

Abstract
We consider the simultaneity bias when examining the effect of individual risk attitudes on entrepreneurship. We demonstrate that entry into self-employment is related to changes in risk attitudes. We further show that these changes are correlated with the probability to remain in entrepreneurship.

Dienstleister bestimmen die Dynamik der Beschäftigung
Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 6,
2016
Abstract
Der in Ostdeutschland deutlich geringere Beschäftigungsaufbau im Vergleich zu Westdeutschland ist maßgeblich darauf zurückzuführen, dass die Impulse der Dienstleistungsbereiche für die gesamtwirtschaftliche Beschäftigung beträchtlich geringer sind als in Westdeutschland. Allerdings nimmt Berlin unter den ostdeutschen Ländern eine Sonderstellung ein, da der dortige kräftige Beschäftigungsaufbau vollständig von den Dienstleistungsbereichen getragen wird. Auf der Kreisebene zeigt sich eine hohe Korrelation zwischen der Beschäftigungsentwicklung insgesamt und der Höhe der Expansionsbeiträge der Dienstleistungsbereiche. Die regional differierenden Expansionsbeiträge der Dienstleistungsbereiche stehen im Zusammenhang mit Unterschieden bei der Teilzeitbeschäftigung, der demographischen Entwicklung sowie der Siedlungs- und Produktionsstruktur.

Taxation and the International Mobility of Inventors
Ufuk Akcigit, Salomé Baslandze, Stefanie Stantcheva
American Economic Review,
No. 10,
2016
Abstract
We study the effect of top tax rates on “superstar” inventors’ international mobility since 1977, using panel data on inventors from the US and European Patent Offices. We exploit the differential impact of changes in top tax rates on inventors of different qualities. Superstar inventors' location choices are significantly affected by top tax rates. In our preferred specification, the elasticity to the net-of-tax rate of the number of domestic superstar inventors is around 0.03, while that of foreign superstar inventors is around 1. These elasticities are larger for inventors in multinational companies. An inventor is less sensitive to taxes in a country if his company performs a higher share of its research there.
