Freie, öffentlichen Meinungsbildung ist das Herzstück der Demokratie. Doch digitale Kommunikation und datengetriebene Kuratierung von Inhalten verändern das der Demokratie eigene Konzept von Öffentlichkeit und erfordern neue gesetzliche Rahmenbedingungen. In diesem Sammelband führen Expert:innen der Rechts- und Politikwissenschaften, der Soziologie und Datenwissenschaft in die Materie ein und weisen Wege zur Stärkung der Demokratie in der Digitalisierung.
'Skelettfund' im Keller
(2021)
Bei der Identifizierung einer unbekannten, stark verwesten Leiche oder eines Skelettes ohne Hinweise auf die Identität durch die Auffindesituation spielt die Erstellung des sog. biologischen Profils eine entscheidende Rolle. Vorgestellt wird ein Leichenfund in einem mehr oder weniger frei zugänglichen Kellerabteil eines Mehrfamilienhauses. Der Leichnam war weitgehend skelettiert, das Skelett jedoch durch mumifizierte Weichteilreste noch nahezu vollständig zusammengehalten. Bei den Hinweisen auf die Identität ergaben sich insbesondere in der Altersschätzung scheinbare Widersprüche, die jedoch zufällig eine relativ genau zutreffende Schätzung lieferten. Die Überreste konnten mittels forensischer DNA-Analyse einer seit 4 Jahren vermissten 49-Jährigen zugeordnet werden. Als Todesursache wurde ein Kältetod diskutiert.
Der Fall wies eine außergewöhnliche Auffindesituation auf, die an Bilder von „Skelettfunden“ in Kriminalverfilmungen erinnerte. Derartige Befunde dürften jedoch in der Realität wohl nur sehr selten vorkommen. Darüber hinaus werden die Wichtigkeit und die Probleme der forensisch-osteologischen Untersuchungen bei der Identifizierung eines stark verwesten, unbekannten Leichnams demonstriert.
Background: Decedents who are repatriated to Germany from abroad are not systematically registered nationwide. In Hamburg, in addition to an epidemic hygienic examination, registration and examination of the content of the documents accompanying the corpses of German citizens has been carried out since 2007. In this way, unclear and non-natural deaths in particular are to be followed up as necessary.
Material and methods: Protocols of external and internal autopsies of German nationals who died abroad and were repatriated to Hamburg via the port or airport between 2007 and 2018 were retrospectively evaluated with respect to numbers, completeness of the autopsy abroad and correctness of manner and cause of death.
Results: Between 2007 and 2018 a total of 703 corpses were repatriated via the port or airport of Hamburg and examined by the Port Medical Service for epidemic hygiene and for anything conspicuous in the documents accompanying the corpse. Of them, 307 corpses were examined at the Institute of Legal Medicine at the University Medical Center Hamburg-Eppendorf. In total, 82.4% of the examined cases had an incorrect, unspecific or incomplete foreign death certificate. Of the deceased, 238 were subjected to a second external autopsy by a forensic pathologist and 69 deceased were autopsied again or for the first time in Hamburg. It was found that 84% of the autopsies performed abroad were not performed according to German and European standards. The most common discrepancy was incomplete preparation of the organs. In almost one quarter of the autopsies performed in Hamburg a different cause of death than abroad was determined at autopsy.
Conclusion: Since the quality of autopsies performed abroad sometimes does not meet the standards in Germany and Europe and many papers accompanying corpses are incomplete or incorrectly filled out, a systematic review procedure in the home country is recommended. Through the system established in Hamburg in 2007, at least a re-evaluation of the cases takes place.
Cryptocurrencies provide a unique opportunity to identify how derivatives impact spot markets. They are fully fungible, trade across multiple spot exchanges at different prices, and futures contracts were selectively introduced on bitcoin (BTC) exchange rates against the USD in December 2017. Following the futures introduction, we find a significantly greater increase in cross-exchange price synchronicity for BTC--USD relative to other exchange rate pairs, as demonstrated by an increase in price correlations and a reduction in arbitrage opportunities and volatility. We also find support for an increase in price efficiency, market quality, and liquidity. The evidence suggests that futures contracts allowed investors to circumvent trading frictions associated with short sale constraints, arbitrage risk associated with block confirmation time, and market segmentation. Overall, our analysis supports the view that the introduction of BTC--USD futures was beneficial to the bitcoin spot market by making the underlying prices more informative.
he ECB is independent, but it is also accountable to the European parliament (EP). Yet, how the EP has held the ECB accountable has largely been overlooked. This paper starts addressing this gap by providing descriptive statistics of three accountability modalities. The paper highlights three findings. First, topics of accountability have changed. Climate-related accountability has increased quickly and dramatically since 2017. Second, if the relationship between price stability and climate change remains an object of conflict among MEPs, a majority within the EP has emerged to put pressure for the ECB to take a more active stance against climate change, precisely on behalf of its price stability mandate. Third, MEPs engage with the climate topic in very specific ways. There is a gender divide between the climate and the price stability topics. Women engage more actively with climate-related topics. While the Greens heavily dominate the climate topic, parties from the Right dominate the topic of Price stability. Finally, MEPs adopt a more united strategy and a particularly low confrontational tone in their climate-related interventions.
Global consensus is growing on the contribution that corporations and finance must make towards the net-zero transition in line with the Paris Agreement goals. However, most efforts in legislative instruments as well as shareholder or stakeholder initiatives have ultimately focused on public companies.
This article argues that such a focus falls short of providing a comprehensive approach to the problem of climate change. In doing so, it examines the contribution of private companies to climate change, the relevance of climate risks for them, as well as the phenomenon of brown-spinning (ie, the practice of public companies selling their highly polluting assets to private companies). We show that one cannot afford to ignore private companies in the net-zero transition and climate change adaptation. Yet, private companies lack several disciplining mechanisms that are available to public companies, such as institutional investor engagement, certain corporate governance arrangements, and transparency through regular disclosure obligations. At this stage, only some generic regulatory instruments such as carbon pricing and environmental regulation apply to them.
The article closes with a discussion of the main policy implications. Primarily, we discuss and evaluate the recent push to extend climate-related disclosure requirements to private companies. These disclosures would not only help investors by addressing information asymmetry, but also serve a wide group of stakeholders and thus aim at promoting a transition to a greener economy.
We provide the first comprehensive analysis of option information for pricing the cross-section of stock returns by jointly examining extensive sets of firm and option characteristics. Using portfolio sorts and high-dimensional methods, we show that certain option measures have significant predictive power, even after controlling for firm characteristics, earning a Fama-French three-factor alpha in excess of 20% per annum. Our analysis further reveals that the strongest option characteristics are associated with information about asset mispricing and future tail return realizations. Our findings are consistent with models of informed trading and limits to arbitrage.
The transition to a sustainable economy currently involves a fundamental transformation of our capital markets. Lawmakers, in an attempt to overcome this challenge, frequently seek to prescribe and regulate how firms may address environmental, social, and governance (ESG) concerns by formulating conduct standards. Deviating from this conceptual starting point, the present paper makes the case for another path towards achieving greater sustainability in capital markets, namely through the empowerment of investors.
This trust in the market itself is grounded in various recent developments both on the supply side and the demand side of financial markets, and also in the increasing tendency of institutional investors to engage in common ownership. The need to build coalitions among different types of asset managers or institutional investors, and to convince fellow investors of a given initiative, can then act as an in-built filter helping to overcome the pursuit of idiosyncratic motives and supporting only those campaigns that are seconded by a majority of investors. In particular, institutionalized investor platforms have emerged over recent years as a force for investor empowerment, serving to coordinate investor campaigns and to share the costs of engagement.
ESG engagement has the potential to become a very powerful driver towards a more sustainability-oriented future. Indeed, I show that investor-led sustainability has many advantages compared to a more prescriptive, regulatory approach where legislatures are in the driver’s seat. For example, a focus on investor-led priorities would follow a more flexible and dynamic pattern rather than complying with inflexible pre-defined criteria. Moreover, investor-promoted assessments are not likely to impair welfare creation in the same way as ill-defined legal standards; they will also not trigger regulatory arbitrage and would avoid deadlock situations in corporate decision-making. Any regulatory activity should then be limited to a facilitative and supportive role.
This paper studies the interactions between corporate law and VC exits by acquisitions, an increasingly common source of VC-related litigation. We find that transactions by VC funds under liquidity pressure are characterized by (i) a substantially lower sale price; (ii) a greater probability of industry outsiders as acquirers; (iii) a positive abnormal return for acquirers. These features indicate the existence of fire sales, which satisfy VCs' liquidation preferences but hurt common shareholders, leaving board members with conflicting fiduciary duties and litigation risks. Exploiting an important court ruling that establishes the board’s fiduciary duties to common shareholders as a priority, we find that after the ruling maturing VCs become less likely to exit by fire sales and they distribute cash to their investors less timely. However, VCs experience more difficult fundraising ex-ante, highlighting the potential cost of a common-favoring regime. Overall the evidence has important implications for optimal fiduciary duty design in VC-backed start-ups.
