Table 3 Evaluation of data quality.
Criterion | Explanation | Example |
|---|---|---|
Time elapsed between events and reporting | Most newspaper articles were published the same day or the next day of the key policy-related event (e.g., the new legislation signed into law, the new policy approved, etc.) | A statement released on November 14, 2017 by the MAS regarding circumstances under which crypto-tokens could be considered to be securities according to Securities and Futures Act (SFA) and the Financial Advisers Act was published the next day (Sundararajan 2017) |
Openness to corrections | Corrections are incorporated in many outlets we used | Washingtonpost’s corrections are stated after: “Correction to this article” |
Range of knowledge and expertise of the person reporting the events | We used articles written by knowledgeable reporters/journalists | We cited one article by coindesk.com reporter Sundararajan (2017) but she wrote hundreds of articles about blockchain/cryptocurrency The sources and authors respected by their peers: WSJ’s MoneyBeat (Vigna 2014) cited news from Coindesk, newsbtc and others cited Brave New Coin, Ripple Insights has been covered by newsbtc and other established sources |
Corroboration from multiple sources | Data and information were triangulated from multiple sources. We also visited the original source as suggested by Joselyn (1977) | Original sources allowed to make updates and corrections: Zagone (2017) reported that Mark Carney was the Chair of the FSB but updated information on the FSB website (https://www.fsb.org/profile/mark-carney/) stated that that was no longer the case |
