International Virtual Experimental Finance Workshop (vEFW)

Sascha Füllbrunn, together with Ernan Haruvy (McGill University, Montreal), hosted the first virtual Experimental Finance Workshop on November 11^th and November 18^th via zoom. On each day, eight speakers presented their current research projects accompanied by discussants. More than one-hundred participants each day listened to talks related to experimental finance methodology, which includes testing market anomalies, understanding trader’s and investor’s behavioural biases or testing decision models, among others.

On the first day, Martin Weber (University of Mannheim, Germany) gave the keynote on the relevance of experiments in finance.

Charles Noussair (University Arizona) held the second keynote about quantile preference together with his view on the methodology.

European participants were attending in the late afternoon, the West-coast US participants had to get up quite early, and Asia-Pacific participants had a long night. Sascha and Ernan used the meeting to talk about the setup of their planned Handbook of Experimental Finance. This meeting was co-presented by the hotspot Integrated Decision Making.

Due to the great success, they scheduled a third meeting on January 13^th 2021 with Brice Corgnet (EM-Lyin Business School) being the keynote speaker. Most of the speakers are already confirmed.

Minister of Finance delivered a research report from IMR researchers to the Tweede Kamer

The Dutch Minister of Finance Wopke Hoekstra delivered the research report “Niet-bancaire kredietverlening – een blik in de black box” by Sascha Füllbrunn, Dirk-Jan Janssen and Utz Weitzel to the Dutch House of Representatives (Tweede Kamer). The research project aimed to open the ‘black box’ of online credit provision in the Netherlands for small companies and self-employed people, for whom the consumer credit protection does not hold. The researchers analysed the web-pages of the credit providers, conducted a survey with the credit takers and the credit providers, and sent registered self-employed people to request credits from the online credit providers (Mystery Shopping).

They find the effective annual rate (jaarlijkse kostenpercentages) within a range of 8% and 421%, depending on the credit amount and duration. The relevant cost factors were often not clearly communicated such that the rates provided are still estimates for some of the credit providers. The credit takers only received detailed information after submitting personal information. Even though the credit providers advertise their background check to be quick and without the necessity to provide plenty of documents, the actual process did not always match the promise as mystery shoppers found out. However, the survey in line with earlier reports shows that the number of credit requests and credit needs was still below 25%. At the very end, those respondents requested regular bank loans often lacking further knowledge about alternative financing opportunities.

The Dutch Ministry of Finance commissioned this project. The researchers got valuable support from the AFM, Stichting MKB Financiering, the Ministry of Economic Affairs and Climate Policy, DYNATA, EXCAP and colleagues from the Institute for Management Research.

Five new innovative education 'proeftuinen' (experimental gardens) were awarded during a festive meeting on 13 June. All the winners will start working on their project in the area of ICT in education in the new academic year. The proeftuinen are facilitated by the ICT in Education programme. One of the winners is Dr Sascha Füllbrunn, Associate Professor of Financial Economics.

Experiential learning

Dr Sascha Füllbrunn will use his proeftuin for “learning by reflecting on what has been done”. In several of the courses within the Economy degree programme, the influence of behavioural prejudice or literacy (financial, risk, graphical) on human decision making is discussed.

Students now learn from theories, but with his proeftuin, Füllbrunn wants to create an environment in which students can experience situations in which they are required to make decisions. Depending on the decision taken, the student will receive feedback. This confronts them with the decision-making process that is related to the theory. This way, the student will gain a better understanding of where the decision-making deviates from optimal behaviour and will hopefully experience a “Eureka! moment”.
