I am not asking you for a random citation of the article, but one that demonstrates the article discusses a puzzle concerning a recent trend, as opposed to a longtime ongoing one.
Your citation of the article:
> This is a puzzle! Why would the market fail to reward innovative firms, or, conversely, why does it continue rewarding less innovative firms? Unfortunately, here we don’t have clear answers.
does not refer to any recent change, indeed, it uses the word "continue" invalidating your claim that the puzzle is about some recent change.
