Research Seminars for 29 April 2024 - 29 April 2024

Online Research Seminar 3:00 pm, Thursday, 28 April 2022 While the literature in the range of Covid-19 related topics has started to examine the market impact of the pandemic, little evidence exists regarding the effect on the German stock index DAX30. This paper fills in the gap by analysing the impact of the COVID-19 pandemic announcements in March 2020 on the German Stock Index DAX30. Using an event study, we investigate how certain industries and specific companies in the index responded to the news, by using three event windows of different length. It mirrors the expectations and trust of the investors [...]

Online Research Seminar 3:00 pm, Thursday, 12 May 2022 Analyses of human reaction to economic incentives reveal contradictory deviations from maximization. For example, underinvestment in the stock market suggests risk aversion, but insufficient diversification of financial assets suggests risk-seeking. The leading explanations for these contradictions assume that different choice environments (e.g., different framings) trigger different biases. Our analysis shows that variation in the choice environment is often not a necessary condition. It demonstrates how certain changes in the incentive structure are sufficient to trigger six pairs of contradictory deviations from maximization even when the choice environment does not change. Moreover, our [...]

Online Research Seminar 3:00 pm, Thursday, 19 May 2022 This paper introduces a new measure of comovement and contagion of crises between countries, applies it to 16 world crises, including the current COVID-19 pandemic, and provides insights regarding the occurrence of contagion during these crises. Our measure demonstrates several important advantages over the extant measures of contagion. Traditional measures of contagion, such as increase in correlation, could be limited in scope since they are bivariate, whereas contagion is often a regional or global market phenomenon. The multiple comparisons that the binary correlations require in such cases could yield inconclusive or contradictory [...]

Online Research Seminar 3:00 pm, Friday, 3 June 2022 An explanation of the break-even effect (Thaler & Johnson, 1990) is that gains cancelling prior losses receive disproportionate higher values. This explanation is proposed and tested for monetary losses as well as lost property. In Experiment 1 (n=107) investigating choices of risky and sure hypothetical monetary outcomes after a prior loss, the results did not show that risk seeking increased when the risky gain cancelled the prior loss. After a reminder of the opportunity cost (what the lost money could have bought), an increase was observed of the frequency of choices of [...]

Online Research Seminar 3:00 pm, Thursday, 23 June 2022 The seminar will be on topics from my ongoing research projects. The first two topics will be on biomedical image analysis projects that I pursue with collaborators. I will start with a novel methodology for MRI image registration. The first involves a statistical estimation of the registration as the non-parametric Bayesian posterior expectation. This estimate undergoes Procrustes analysis to give a rigid transformation. I will show applications of the method to MRI data of a variety of anatomic regions and imaging contrasts. I will then present a methodology to track as well [...]

Online Research Seminar 3:00 pm, Thursday, 7 July 2022 H2H Marketing takes the groundbreaking B2B marketing and branding principles and combines them with new ideas and concepts. Combing Philip Kotler’s “Marketing 5.0” and the “Mensch Marketing” developed by Uwe Sponholz and Waldemar Pfoertsch will help to shape this modern way of thinking about and doing marketing. H2H Marketing offers a smart, systematic plan to help any organization move away from conventional marketing and create value propositions for all relevant stakeholders. You don’t have to be an entrepreneur or techie to take advantage of their insights; you only have to be willing [...]

Online Research Seminar 18:30 pm, Thursday, 29 September 2022 Perceived long-term (ten-year horizon) return distributions are remarkably bearish and most individuals believe that uncertainty is only marginally greater in the long term than the near term (one-year horizon), resulting in inferred variance ratios that require unprecedented levels of mean reversion. Although respondents’ near-term beliefs are extrapolative, long-term beliefs are counter-cyclical. Long-term beliefs are more important than near-term beliefs in explaining equity market participation. Respondents agree more about long-term than near-term returns and respondents’ characteristics better explain long-term, versus near-term, belief heterogeneity. These patterns have important implications for understanding household finance and [...]

Online Research Seminar 15:30 pm, Thursday, 27 October 2022 Smart cities are ones that deploy innovative technology, create more innovative ways of delivering public services and make better use of data with the ultimate objective of becoming more prosperous, sustainable and a better place to live. Smart environments are usually built on a network of sensors and Internet of Things (IoT) sensing devices to enable real-time monitoring and response. Data collected from the IoT network can be processed both in real-time and a posteriori to provide insights for advancing and automating processes within and for the urban city environment. A large [...]

Online Research Seminar 15:30 pm, Thursday, 3 November 2022 As any other large-scale crisis, the COVID-19 pandemic one was characterised by enormous levels of uncertainty due to overload of information that generates complexity. This complexity in turn can enhance fear and of course panic at both individual and collective level. However, beyond your personal, family and social safety that is a priority, there is another threat in the air. People management is under threat. Our ability to lead people for various projects and processes through this crisis is very important. Our actions as leaders will highly affect the level of the [...]

Online Research Seminar 15:30 pm, Thursday, 8 December 2022 We conduct experiments on a rich set of repeated games with high discount factors ( = 0.99; 0.995) and develop two pattern-mining methods to study the long run. Our approach emphasizes learning within a repeated game and documents its consequences. Whether, how and what patterns emerge are the subjects of this paper. We find that there is more stability, more efficiency, and more equality at the end of play than at the beginning. Moreover, subjects reach more complex agreements over time. We are also able to detect typical story lines relating long [...]

Online Research Seminar 15:30 pm, Thursday, 26 January 2023 Using fresh data about US companies that announced they were suspending their business activities in Russia following the invasion of Ukraine, we test how their decision affected their prices and looking-forward volatility. We find that these firms, on average, experienced a reduction (increase) in their value (implied volatility). However, this reduction (increase) did not last more than one to two weeks. More in depth analysis shows variations across economic sectors following the announcement. In terms of returns, the energy sector benefited the most, technology was relatively stable, while consumer goods experienced the [...]

Online Research Seminar 16:30 pm, Thursday, 16 February 2023 The talk will discuss how to incorporate biometric tools to study business decision making. Part of the conversation will deal with the basics of biometric tools, different sensors that are commercially available, platforms to analyze data, and the type of research questions that can and cannot be answered by using biometric tools. The lecture will also address some of the challenges associated with using biometric tools, such as individual differences in participants, privacy concerns, data security, and ethical considerations. Attendees will also learn about the various ways in which these challenges can [...]
