过去，经济学家获得诺贝尔奖是因为他们向公众阐释了之前仅仅为经济学家才能理解的东西；现在，经济学家获得诺贝尔奖是因为他们向其经济学同行阐释了公众一向都很清楚的东西。

原文在此：

Economists used to win the Nobel prize for explaining to the general public something that previously only economists understood, but now they win it for explaining to their fellow economists something that the general public has always known, e.g.:

• Politicians care about themselves (Buchanan).
• Don’t put all your eggs in one basket (Markowitz, Miller,and Sharpe).
• You can’t fool all of the people all of the time (Lucas).
• Some people know more than others (Akerlof, Spence, Stiglitz).
  

Deaton’s major insight: aggregate measures of consumption and inequality conceal important differences among individuals.
