I've been cut off <a href=" http://ied.edu.br/cheap-tetracycline.pdf ">buy tetracycline antibiotics free shipping</a> Science is about forming theories and then testing and revising those theories, and economists such as Esther Duflo and Al Roth, who have dedicated their careers to using economic experiments to learn about the world, are probably particularly upset by the authors&#8217; characterization of economics. (I would venture to guess that most empirical economists, especially micro people, get pretty ragey upon hearing this classification.) Granted, sometimes it&#8217;s difficult to collect data (I&#8217;m still trying to figure out how to randomize the country into &#8220;tax cut&#8221; and &#8220;non tax cut&#8221; conditions, for example), but that doesn&#8217;t mean that people aren&#8217;t trying. In any case, this science versus not science thing is a bit of an irrelevant semantic dispute, and the prudent consumer of economics is better served by simply asking for supporting data rather than arguing labels.
