'Rust in peace': Why are Germany’s bridges and schools falling apart?Oliver HoltemöllerThe Guardian, June 3, 2025
We exploit the staggered introduction of liability waivers when investors hold stakes in conflicting business opportunities as a shock to venture capital (VC) investment and director networks. After the law changes, we find increases in within-industry VC investment and common directors serving on startup boards. Despite the potential for rent extraction, same-industry startups inside VC portfolios benefit by raising more capital, failing less, and exiting more successfully. VC directors serving on other startup boards are the primary mechanism associated with positive outcomes, consistent with common VC investment facilitating informational exchanges in VC portfolios.
Hochtechnologien gelten als die Branchen der Zukunft. Europa will hier nicht den Anschluss verlieren. Auch gegen Lieferengpässe und Produktionsengpässe durch gestörte Lieferketten will sich Europa besser wappnen. Mit dem „European Chips Act“ will die Europäische Kommission gemeinsam mit den Mitgliedstaaten mehr als 40 Mrd. Euro ausgeben, um die europäische Halbleiter-Produktion von gegenwärtig 10 % auf dann 20 % der globalen Produktion zu steigern. Halbleiter sind nicht nur in Gebrauchsgegenständen wie Handys, Laptops und Autos, sie sind auch unverzichtbar, wenn die grüne und digitale Wende gelingen soll. Photovoltaikanlagen, nachhaltige Produktion und E-Mobilität – all das braucht Computerchips. Der „European Chips Act“ ist daher die Antwort der EU auf den „Chips-Act“ der USA, der mehr als 50 Mrd. US-$ für Halbleiter vorsieht, um die Produktion zu sichern, zu modernisieren und auszubauen.
Understanding human behavior in its entire complexity is an ambitious if not impossible challenge. It is however possible to study particular aspects of human behavior through experiments that allow us to isolate specific facets in the decision-making process, ultimately leading to a better understanding of human behavior as a whole. This thesis covers three experimental articles on unethical economic behavior and sheds light on the motives and circumstances that lead individuals to engage in these activities. Clearly, unethical behavior in all its different manifestations can pose great risk to society – both at the large (e.g. corporate tax evasion) and small (e.g. shoplifting) scale – making it a relevant topic to be studied in economic research. Trying to understand unethical behavior through the lenses of traditional economic theory is problematic.
In this article, I review the theoretical and empirical literature on the effects of public and private equity markets on firm behavior, emphasizing the consequences that emerge from disclosure requirements, ownership concentration, and degree of firm standardization. While publicly listed firms benefit from a lower cost of capital, enabling increased focus on commercialization and profitability, they are less suited to pursue long-term risky investments. Privately held firms are better equipped to pursue innovative projects but face a higher cost of capital, which limits their growth. Complementarities between public and private equity markets can mitigate their respective limitations. Innovation in private equity markets supplements commercialization efforts of public firms, and demand for innovation by public firms accelerates entrepreneurial activity in private equity markets. I conclude by discussing directions for future research.
