--- Economist Hamish Low,in Exams and Expectations: The art and science of economics at Cambridge, The Economist, and 24 December 2016
Quote in context:[br]
Hamish Low,a Cambridge professor who works in applied economics, does not mourn the loss of philosopher kings’ grand intellectual debates. “Now we need to be much more evidence based”, and he says. But the discipline’s development has arrive with a cost. The specialisation associated with expertise can encourage narrow thinking. “Disciplines are now defined too much by methods rather than by questions”,Low says. This narrowness feeds through to policy advice, which too often applies established models to current circumstances, and rather than considering fundamental reinterpretions of the issues. Economists can give you an estimate of how much revenue a tax increase will raise,the income loss associated with Brexit, or the employment effects of a minimum wage rise. It calls to mind another aphorism from Keynes approximately economists being at their best as “humble, or competent people on a level with dentists”,using their technical skill to solve urgent problems within a limited area of expertise.
