August 30, 2020: In a new paper I (together with Maria Kristalova and Michael Wyrwich) investigate the effect of initial conditions at the end of the socialist period in East Germany for new business formation after German unification. We find a very important role of the levels of remaining self-employment and the share of employees with a university degree in the year 1989 for start-ups in general as well as for new businesses in innovative manufacturing industries. These differences have pronounced historical roots. Adequate policies should account for these initial conditions. We introduce a classification of East German regions with regard to the initial levels of self-employment and qualification of the workforce. See  https://ideas.repec.org/p/jrp/jrpwrp/2020-014.html

Abstract: We investigate the reasons for the pronounced regional differences of new business formation after the transformation from a socialist planned system to a market economy in East Germany. Relatively high start-up rates are found in regions that had a well-qualified workforce and a relatively high share of remaining self-employed at the end of the socialist period. This also holds for high-tech manufacturing start-ups. Based on our conclusion that policy should account for these initial regional conditions, we use two criteria to introduce a classification of regions.

June 7, 2020: Here is a new Working Paper: Michael Fritsch, Maria Kristalova and Michael Wyrwich: Regional trajectories of entrepreneurship: the effect of socialism and transition. https://ideas.repec.org/p/jrp/jrpwrp/2020-010.html

Abstract: We investigate how major historical shocks affect regional trajectories of economic activity. To this end, we conduct a comparative analysis of the development of entrepreneurship in East and West Germany after World War II. The introduction of an anti-entrepreneurial socialist economy in East Germany in 1949, and the subsequent transformation to a market economy four decades later were major historical shocks to the economy in general, and to entrepreneurship specifically. Our comparative analysis of East and West Germany assesses how these shocks affected the level of entrepreneurship at the regional level. Surprisingly, our results show that socialism does not have a long-run negative effect on the prevalence of self-employment in East Germany, despite the severe anti-entrepreneurial policies prevalent in Soviet-style socialism. Quite to the contrary, there is actually a positive treatment effect of German separation and reunification. Further analyses suggest that current structural differences in regional levels of self-employment in Germany are not pre-dominantly due to the socialist legacy of the East, but mainly a result of the shock transformation that occurred with reunification.

April 21, 2020: Finally out: Michael Fritsch and Michael Wyrwich „Langfristige regionale Trends unternehmerischer Selbständigkeit reflektieren unternehmerische Kultur“ (Long-term regional trends of self-employment reflect entrepreneurial culture). In Katharina Hölzle, Victor Tiberius and Heike Surrey (eds.): Perspektiven des Entrepreneurships: Unternehmerische Konzepte zwischen Theorie und Praxis. 447-460 (Ch. 33), Stuttgart: Schäffer-Poeschel.

Zusammenfassung: In vielen Regionen ist das Niveau unternehmerischer Selbständigkeit über längere Zeiträume sehr persistent. Diese Persistenz zeigt sich auch dann, wenn die regionale Wirtschaft drastischen Änderungen der wirtschaftlich-gesellschaftlichen Rahmenbedingungen ausgesetzt war. Eine Erklärung für diesen Befund besteht darin, dass ein hohes Niveau an unternehmerischer Selbständigkeit mit einer unternehmerischen Kultur verbunden ist. Solch eine unternehmerische Kultur lässt sich als eine informelle Institution auffassen, die sich nur über relativ lange Zeiträume verändert. Wir beschreiben die verschiedenen Elemente einer solchen Kultur unternehmerischer Selbständigkeit und gehen auf ihre Bedeutung für regionale Entwicklung ein. Abschließend weisen wir auf wirtschaftspolitische Implikationen sowie auf weiteren Forschungsbedarf hin.

April 18, 2020: The Corona crisis keeps me and my co-authors busy. Here are some new papers:

Henriette Ruhrmann, Michael Fritsch and Loet Leydesdorff: Smart Specialization Strategies at National, Regional, or Local Levels? Synergy and Policy-making in German Systems of Innovation. : https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3577495

Abstract: Employing a quantitative, data-driven tool – the Triple Helix Indicator – to microdata of firms in Germany, we develop an evidence base for innovation-policy strategies. We aim to answer the question which level of government (local, regional, national) might be most effective for strategic innovation policy-making based on smart specialization in Germany. The empirical results show that the country is decentralized to the extent that it cannot be considered a “national” innovation system. More than two-thirds of innovation-system synergy is generated at the lower levels of districts (NUTS3) and Governmental Regions (NUTS2). In high-tech and medium-tech manufacturing, former East and West Germany, as well as North and South Germany, can be considered separate sub-national innovation systems. These findings strengthen the case for region- and context-specific innovation policies. The results illustrate the value of the Triple Helix Indicator for systematic regional mapping and serve as evidence for policy-makers to expand RIS3 policy strategies to the regional and local level in Germany.

Michael Fritsch, Martin Obschonka, Fabian Wahl and Michael Wyrwich: The Deep Cultural Imprint of Roman Sandals: Evidence of  Long-lasting Effects of Roman Rule on Personality, Economic Performance, and Well-Being in Germany. https://ideas.repec.org/p/jrp/jrpwrp/2020-005.html

Abstract: We investigate whether the Roman presence in the southern part of Germany nearly 2,000 years ago had a deep imprinting effect with long run consequences on a broad spectrum of measures ranging from present-day personality profiles to a number of socioeconomic outcomes and why. Today’s populations living in the former Roman part of Germany score indeed higher on certain personality traits, have higher life and health satisfaction, longer life expectancy, generate more inventions and behave in a more entrepreneurial way. These findings help explain that regions under Roman rule have higher present-day levels of economic development in terms of GDP per capita. The effects hold when controlling for other potential historical influences. When addressing potential channels of a long term effect of Roman rule the data indicates that the Roman road network plays an important role as a mechanism in the cultural imprinting that is still perceptible today.

March 4, 2020: Michael Wyrwich and I have published two new Working Papers on the geographic concentration of innovation activity. In these publications we challenge the common belief that innovation activities are considerably more successful and productive in large cities.

In the paper „Is innovation (increasingly) concentrated in large cities? An international comparison“ https://ideas.repec.org/p/jrp/jrpwrp/2020-003.html we investigate the geographic concentration of patenting in large cities using a sample of 14 developed countries. There is wide dispersion of the share of patented inventions in large metropolitan areas. South Korea and the US are two extreme outliers where patenting is highly concentrated in large cities. We do not find any general trend that there is a geographic concentration of patents for the period 2000-2014. There is also no general trend that inventors in large cities have more patents than in rural areas (scaling). Hence, while agglomeration economies of large cities may offer advantages for innovation activities, the extent of these advantages is not very large. We conclude that popular theories over-emphasize the importance of large cities for innovation activities.

The second paper „Does Successful Innovation Require Large Cities? Germany as a Counterexample“ https://ideas.repec.org/p/jrp/jrpwrp/2020-004.html deals with the geograph of innovation in Germany. The country provides a clear couterexample to theories that highlight the role of large cities for innovative activity.  We argue that a main force behind the geography of innovation in Germany is the country’s federal tradition that has shaped the settlement structure, the geographic distribution of universities and public research institutions, as well as local access to finance. We demonstrate the long-lasting effect of the historical political structure and distribution of knowledge sources on innovation activities today. We conclude that historical factors that shape the settlement structure and location of knowledge sources are of key importance for the geographic location of innovation activities.
