Korbinian von Blanckenburg

Korbinian von Blanckenburg (born May 25, 1979 in Göttingen ) is a German economist . He is Professor of Economics and Business Mathematics and Dean of the Department of Economics at the Technical University of Ostwestfalen-Lippe in Lemgo .

Career

After graduating from high school at Hainberg-Gymnasium Göttingen, Korbinian von Blanckenburg studied economics at the University of Regensburg , the University of Karlstad in Sweden and the Westphalian Wilhelms University of Münster . In his doctoral thesis he then developed test procedures for assessing the functionality of markets. After positions at the German Institute for Economic Research , WINGAS GmbH and a three-semester teaching position at the Institute for Economics at the University of Kassel , he was appointed professor in October 2013. In 2016 he completed his habilitation at the University of Kassel and was granted a license to teach economics.

Virtual Reality Lecture

Korbinian von Blanckenburg developed 360 ° videos with VR elements for his YouTube channel. With these 360 ° videos , he gives his students a completely new opportunity to experience the lecture. The difference to the conventional learning video: The students not only see their professor, but can also go to a virtual lecture hall with a playback medium of their choice. The YouTube videos allow a 360-degree view through the lecture hall including fellow students. Graphics and curves appear as clear 3D structures in space. The audience is given tasks and must actively move through the virtual space in order to be able to count. The VR lectures are publicly available at youtube.com/wirliebenmathe.

Mathematics in business administration

Korbinian von Blanckenburg is the author of the textbook "Mathematics in Business Administration". This book is deliberately written in an application-oriented manner; H. understandable and with various practical examples. It is aimed at students of business administration. Evidence and deductions are largely dispensed with. In order to deepen the subject matter, QR codes have been inserted in many places, which link to live recordings and short summaries from Korbinian von Blanckenburg's lectures.

Research priorities

Research on time change

Korbinian von Blanckenburg, together with his co-author Julian Strauch, published a study on electricity savings in private households. The analysis shows that the time change does not result in any energy savings compared to a pure summer time. On the contrary, with a year-round summertime, private households use even less electricity. The authors justify this on the basis of the specifics of daily electricity consumption: Households consume the most energy in the evening hours. In addition, less electricity is used when it is brighter. Conversely, private households consume less energy with a system with year-round summer time than with the time changeover, since the effects of more brightness in the evening hours can be used from early spring and not from the end of March. In the current debate about the abolition of the time change at EU level, Korbinian von Blanckenburg warns of a patchwork quilt in Europe. If each EU member state can decide for itself whether it will stay in summer or winter time in the future, there is a particular risk of economic damage. Additional time zones would have a negative impact on trade and foreign investment. The economist advocates a coordinated European solution. This could, for example, still consist of three time zones. In his opinion, it would also be conceivable to rethink behavior, especially in winter. Accordingly, school and work start times should be postponed in the case of a year-round summer time. In this way one would use the effect of the longer evening brightness and at the same time not suffer from the longer darkness in the morning. This adaptation of the way of life to the daylight then also corresponds to the natural biorhythm - which is classically used as a counter-argument to year-round summer time. The economist also discusses the possibility of a regulated world time , as the pilots already have.

The System of Cartel Markers (SCM): A cartel screening process

Korbinian von Blanckenburg and his co-authors Alexander Geist and Konstantin Kholodilin developed the so-called System of Cartel Markers (SCM). It is a cartel screening process based on the idea that a cartel leaves suspicious traces in empirical data in its activities. The SCM takes into account:

  1. The degree of capacity utilization: During the cartel formation phase, cartels tend to increase prices and / or reduce quantities. Assuming that the capacities remain unchanged in the short term, a low capacity utilization is expected.
  2. The correlation between the degree of capacity utilization and price changes: Due to the constant occurrence of exogenous disturbances, it is assumed that markets are mostly in imbalance. Therefore, the approach of this marker is directed towards the adjustment of the price after an exogenous disturbance. In competition, a demand shock first leads to higher capacity utilization (providers suddenly face a large number of inquiries). In the next step, a price adjustment is expected (after a positive demand shock, a price increase). This correlation can be measured empirically (although the delay must of course be taken into account). In principle, an existing cartel also reacts to exogenous changes. In the search for the (new) Cournot level, however, such adjustments take place more slowly (agreement within the cartel). The cartel formation phase is an exception, as prices are initially set completely independently of the actual market development (until the maximum profit level has been reached in the cartel's opinion).
  3. The return differential (to a higher-level industry): Excess returns are expected.
  4. Correlation between the yield difference and changes in capacity: In a competitive market, a positive correlation between the yield difference and the changes in capacity is expected. For example, if an industry generates excess returns (because the products have become fashionable), on the one hand this attracts new companies and on the other hand leads to the expansion of the (fully utilized) capacities of previous market participants. Both effects are reflected in a positive change in capacity for the entire industry. In contrast, sub-returns lead to the drop-out of participants and a reduction in capacity. In a cartel phase (when the members agree on their investments), however, no short-term change in capacity is to be expected as long as the existing (underutilized) capacities are sufficient. It is therefore expected that both the establishment of the cartel and the cartel phase will be independent of the yield difference and changes in capacity.
  5. Distribution of price changes: In cartel activities, a higher density of price change distribution around zero is expected, since cartels tend to coordinate prices with one another. This has also been proven empirically.

Memberships

Awards

  • Roman Herzog Research Prize Social Market Economy 2018

The prize was awarded by Blanckenburg for his habilitation “Development of competitive economic methods to detect and reduce abuse of market power”. In it he shows ways to identify competitive defects and analyzes relevant empirical case studies. It is primarily about competition policy and cartel formation.

  • Teaching Award 2015 (Ostwestfalen-Lippe University of Applied Sciences)

Von Blanckenburg received the teaching award for his high level of commitment in his lectures.
