     Whether or not we believe in astrology is irrelevant; the question is, did the Magdalenians? If so, then in a self-fulfilling prophecy they may have been organizing their lives according to a religious belief system, and not simply an economic or ecological one.

   • 2011 August 7, Paul Krugman, “A Self-Fulfilling Euro Crisis? (Wonkish)”, in The New York Times‎^[1], archived from the original on 11 July 2022:

     The big question, I believe, is whether the Italian and maybe Spanish crises are the kind of thing that might be brought under control by ECB bond purchases. This is often phrased in terms of whether they are facing liquidity or solvency problems; but I think it’s better phrased in terms of the possibility of self-fulfilling crises, a la Obstfeld. […] So there is a reasonable case that what we’re seeing in Italy is a self-fulfilling crisis trying to happen, in which fear of default is precisely what leads to default.
