how would economists predict a bubble, economists wouldnt agree on the detergent used,the frequency,the size and at the end of the day thats essentially what they are trying to predict,how often are they right well if one thousand get together one might get close to the mark.
a big reason why we had a gfc is economic theory relative to human nature,that somehow the yin and the yang would level the playing field and look what resulted with greedy human beings whose appetite is never satisfied
