CURRENT EVENTS / AKTUELLES

May 2, 2021:

My paper „Is innovation (increasingly) concentrated in large cities? An international comparison“ (with Michael Wyrwich) appeared in a regular issue of  Research Policy (vol. 50, art. no. 104237. https://doi.org/10.1016/j.respol.2021.104237 We show that even high quality inventions are NOT concentrated in large metropolitan areas in most countries – the US (together with South Korea and Japan) is an extreme outlier in this respect. We conclude that while the agglomeration economies found in large cities may offer advantages for innovation activities, the extent of these advantages is not significant, and popular theories overemphasize the importance of large cities for innovation activities.

April 27, 2021: Next Thursday (April 29) Korneliusz Pylak, Michael Wyrwich and I present our paper „Historical Roots of Entrepreneurship in Different Regional Contexts—The Case of Poland“ in the Creative Spark-Workshop, 9:30-10AM (CET). From 10:00-10:25 Maria Greve will then present our work on „Path-dependence and historical shocks: Surprising evidence from (self-employment in) Germany“.

April 6, 2021: There is a widely held belief that agglomeration economies encourage significantly more successful and productive innovation activities. In a new paper („Is innovation (increasingly) concentrated in large cities? An international comparison“) that has just been published online in Research Policy, Michael Wyrwich and I investigate the geographic concentration of patented inventions in 14 developed countries. We find that in most countries patenting is geographically dispersed with considerable shares of patented inventions in areas other than large cities. Also, there is no general tendency that inventors in large cities are more productive, in terms of filing patents, when compared to inventors in rural areas. We conclude that while the agglomeration economies found in large cities may offer advantages for innovation activities, the extent of these advantages is not significant, and popular theories overemphasize the importance of large cities for innovation activities.

March 16, 2021: My paper „Types of Institutions and Well-Being of Self-Employed and Paid Employees in Europe“ together with Alina Sorgner and Michael Wyrwich was now published in a regular issue of Small Business Economics, vol 56 (2021), 877-901. https://doi.org/10.1007/s11187-019-00274-2  The results clearly indicate that fostering an entrepreneurial society in Europe is a welfare-enhancing strategy that benefits both, the self-employed and paid employees. In contrast to a widespread belief our findings suggest that labor market institutions
do not play an important role for well-being of self-employed as well as paid employees.

March 14, 2021: Korneliusz Pylak, Michael Wyrwich and I will present our work on historical roots of regional entrepreneurship in Poland in a Zoom workshop next Thursday, March 18, at 5 pm (CET). This is part of a mini-series of five Workshops on the „The Evolution, Persistence and Success of Entrepreneurial Ecosystems“. You can register at https://cardiff.zoom.us/meeting/register/tZIpcOyprz0oG9MZLWoMRXXCNNqOFNHEiFfn

Here is the program of the whole Workshop series (all in UK time) Workshop Series – The Evolution, Persistence and Success of Entrepreneurial Ecosystems.

March 5, 2021: My paper „Micro dynamics and macro stability in inventor networks“ with Muhamed Kudic in Journal of Technology Transfer is now available online first at https://doi.org/10.1007/s10961-021-09851-8. Based on co-patenting data of the entire population of West German inventors in the field of laser technology, we analyze the development of their network from the onset of the technology in the early 1960 over a period of 45 years. A main focus is on the highly dynamic processes at the micro-level of inventors and their ties that seem to inconsistent with the remarkable stable structures at the macro level.

February 18, 2021: Happy to announce that my paper “Synergy and Policy-making in German Innovation Systems—Smart Specialization Strategies at National, Regional, Local Levels?” with Henriette Ruhrmann and Loet Leydesdorff in Regional Studies is now available online first at https://doi.org/10.1080/00343404.2021.1872780. We apply a Triple Helix Indicator to assess synergy generated in regional innovation systems and find a high share of total synergy generated at the regional and the local level.

January 21, 2021: Very sad news! My colleague, co-editor and good friend Johannes Broecker passed away last Tuesday evening. He was rather optimistic that his incurable illness would allow him to live much longer. We lost an enthusiastic scientist. My thoughts are with him and with his family. RIP Dear Johannes!

January 21, 2021: Together with Maria Kristalova, Michael Wyrwich, and further international colleagues I co-organize two special sessions on “Historical Roots of Regional Entrepreneurship and Innovation” and “Linking entrepreneurship and regional policy”  at this year’s ERSA congress “Territorial Futures – Visions and scenarios for a resilient Europe” (Bolzano, Italy, https://ersa.org/events/60th-ersa-congress-2/). All interested participants are cordially invited to submit their abstracts for both special sessions until March 9!

January 15, 2021: My paper „One Transition Story Does Not Fit Them All: Initial regional conditions and new business formation after communism“ (with Maria Kristalova and Michael Wyrwich) was accepted for publication in the journal Post-Communist Economies. The Working Paper version can be found here https://EconPapers.repec.org/RePEc:jrp:jrpwrp:2020-014.

January 02, 2021: Back to work! I very much hope that 2021 will be a good year for all of us with many improvements that bring us back to normal.

October 27, 2020: Great new paper with Michael Wyrwich „Initial Conditions and Regional Performance in the Aftermath of Disruptive Shocks: The Case of East Germany after Socialism“ We confirm that entrepreneurship an knowledge are the key drivers of growth, particularly in turbulent times. See: 2020 F&W Initial Conditions JERP 2020-017

Abstract: We investigate how initial conditions that existed in East Germany at the end of the socialist regime impact regional development during the turbulent shock transition to a market economic system. Our investigation spans a period of almost 30 years. Both the self-employment rate (an indication of the existence of a pre-socialist entrepreneurial tradition) and the share of the workforce with a tertiary degree have a strong positive effect on regional development. We conclude that knowledge and a tradition of entrepreneurship have long-run positive effects on development in regions that face disruptive shocks. Entrepreneurship and knowledge play a less important role for development across West German regions, where no significant shocks occurred.

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.
