Abstract
Purpose
Important research once thought unassailable has failed to replicate. Not just in economics, but in all science. The problem is therefore not in dispute nor are some of the causes, like low power, selective reporting, the file drawer effect, publicly unavailable data and so forth. Some partially worthy solutions have already been offered, like pre-registering hypotheses and data analysis plans.
Design/methodology/approach
This is a review paper on the replication crisis, which is by now very well known.
Findings
This study offers another partial solution, which is to remind researchers that correlation does not logically imply causation. The effect of this reminder is to eschew “significance” testing, whether in frequentist or Bayesian form (like Bayes factors) and to report models in predictive form, so that anybody can check the veracity of any model. In effect, all papers could undergo replication testing.
Originality/value
The author argues that this, or any solution, will never eliminate all errors.

Abstract
Purpose
With the introduction of the Markets in Financial Instruments Directive (MiFID), financial institutions are faced with many investor protection provisions; this has a major impact on the day-to-day operations of private banks, which provide investment services to predominately retail or non-professional investors. The purpose of this paper is to determine how MiFID provisions regarding investor protection with respect to suitability are complied with in practice by private banks.
Design/methodology/approach
Based on interviews with 25 representatives of private banks from 10 different European Union (EU) member states, the researchers have determined how these provisions are fulfilled and associated risks mitigated. Mapping out the suitability requirements of MiFID and comparing them with how these have been operationalised, we arrive at the question of whether this leads to a level playing field and investor protection by different private banks.
Findings
Although MiFID is trying to achieve a level playing field between the EU member states, this study shows that this has not been achieved in all areas. Investor protection requirements from MiFID are interpreted and operationalised differently. Although these differences are sometimes small, sometimes they are larger and affect the way the investor is served and suitability determined.
Originality/value
This research provides a unique insight into the way private banks in Europe have implemented the MiFID II requirements and gives insight into best practices. For the future, this research can serve as a prelude to in-depth follow-up research on the implementation of EU provisions.
