Die Studie untersucht die Potenziale und Herausforderungen von modernen Technologien im Bereich Lieferkettenverantwortung, mit einem besonderen Fokus auf Blockchains. Derartige Technologien bieten Dank der Dezentralität und der zugrundeliegenden kryptographischen Verfahren die Möglichkeiten,...

Rating agencies report ordinal ratings in discrete classes . We question the market's implicit assumption that agencies define their classe s on identical scales, e.g., that AAA by Standard & Poor's is equivalent to Aaa by Moody's. To this end, we develop a non-parametric method to estimate the...
