"But what it's led to is this sense of impunity that is really stunning and you feel it on the individual level right now. And it's very very unhealthy, I have waited for four years, five years now to see one figure on Wall Street speak in a moral language.
And I've have not seen it once. And that is shocking to me. And if they won't, I've waited for a judge, for our president, for somebody, and it hasn't happened. And by the way it's not going to happen any time soon, it seems."
Jeffrey Sachs
“Some economists, when thinking about long memory, are concerned that it undercuts the Efficient Market Hypothesis that prices fully reflect all relevant information; that the random walk is the best metaphor to describe such markets; and that you cannot beat such an unpredictable market. Well, the Efficient Market Hypothesis is no more than that, a hypothesis. Many a grand theory has died under the onslaught of real data.” Benoît B. Mandelbrot
