While scientific findings need to be assessed by peers and journal referees, the confidentiality of original data often makes the process arduous. An accredited organization launched by Christophe Pérignon (HEC Paris) and colleagues with access to the original research data can now ensure reproducibility of results. This not only promises huge gains in time and effort for researchers but will also shore up trust in scientific results.
In this article we share testimonials from our professors about their personal experience with online education.

As the Single Supervisory Mechanism (SSM), the system of supervision for Euro Area banks centered on the European Central Bank (ECB), is now well into its fifth year of operation, the financial press offers constant reminders of the role of regulation and supervision in shaping the decisions of large multinational banks (MNBs). In particular, recent examples have highlighted their impact on banks’ locational choices, be it in the case of banks relocating some of their operations from London to other European cities in the anticipation of Brexit, or in the case of CommerzBank, which may soon become the target of a European cross-border bank merger.
In our recent research published in the Journal of Financial Economics, we analyze price formation in a context in which dealers repeatedly compete for the opportunity to trade with retail traders. We characterize equilibria in which dealers’ pricing strategies are optimal irrespective of the private information that each dealer may possess. We propose a robust model that predicts how the dealers share information and equilibrate the trade.
