Recently, the problems associated with the existing journal review processnaroused discussions from seasoned management researchers, who have also made useful suggestions for improving the process. To complement these suggestions, we propose a more radical change: a manuscript should be reviewed on an “as is”nbasis and its fate be determined in one round of review. The as-is review process shortens the time period from submission to final acceptance, reduces thenworkload of editors, referees and authors, provides frank author feedback to referees, and, most important, lets authors own all of the ideas in their publications.
Confidence intervals in econometric time series regressions suffer from notorious coveragenproblems. This is especially true when the dependence in the data is noticeable andnsample sizes are small to moderate, as is often the case in empirical studies. This papernsuggests using the studentized block bootstrap and discusses practical issues, such as thenchoice of the block size. A particular data-dependent method is proposed to automate the nmethod. As a side note, it is pointed out that symmetric confidence intervals are preferred over equal-tailed ones, since they exhibit improved coverage accuracy. The improvements in small sample performance are supported by a simulation study.
In Zeiten zunehmenden Kostendruckes gewinnt Business Process Outsourcing (BPO), die Auslagerung einzelner Prozesse an externe Dienstleistungsanbieter, bei Banken an Bedeutung. Dies trifft insbesondere auf die Abwicklung von Wertschriftentransaktionen zu, welche von Banken vermehrt nicht mehr selbst erbracht, sondern an spezialisierte Dienstleistungsanbieter ausgelagert wird.
Der Autor befasst sich im vorliegenden Werk mit Business Process Outsourcing-Dienstleistungen im Wertschriftenbereich, welche in der Schweiz sowohl von regulierten BPO-Anbietern mit Bank-/Effektenhändlerlizenz als auch von BPO-Anbietern ohne entsprechende Lizenzen angeboten werden. In Bezug auf das Dienstleistungsangebot sowie den Zugang zur Finanzmarktinfrastruktur (Börsen, Clearing- und Settlement-Organisationen etc.) unterscheiden sich die beiden ungleich regulierten BPO-Anbieter voneinander. Damit verbunden sind verschiedene Ertrags-, Kosten-, Risiko- und Kundenbindungsaspekte, welche es bei der ökomischen Beurteilung der einzelnen BPO-Modelle zu berücksichtigen gilt. Das hierfür entwickelte Beurteilungsmodell kann dabei als Hilfsinstrument dienen.
This book presents a selection of ten papers on three specific fields of financial market research. As a help for readers, the table below shows the field to which each paper belongs, and lists the title, author(s) and place or state of publication. Most of these articles went through a
peer-review process1 and have already appeared in scholarly journals or books.
While focusing on different areas, my papers have the common goal of enhancing the understanding of financial markets, in particular of shedding light on seemingly inefficient aspects of the financial markets and the behaviour of traders.
