Greg Ip at The Economist:
No, micro is not the "good" economics: If asked to compile a list of economists’ mistakes over the last decade, I would not know where to start. Somewhere near the top would be failure to predict the global financial crisis. Even higher on the list would be failure to agree, five years later, on its cause. Is this fair? Not according to Noah Smith: these, he says, were not errors of economics but of macroeconomics. Microeconomics is the good economics, where economists by and large agree, conduct controlled experiments that confirm or modify established theory and lead to all sorts of welfare-enhancing outcomes.
To which I respond with two words: minimum wage..., ask any two economists – macro, micro, whatever – whether raising the minimum wage will reduce employment for the low skilled, and odds are you will get two answers. Sometimes more. (By contrast, ask them if raising interest rates will reduce output within a year or two, and almost all – that is, excepting real-business cycle purists – will say yes.)
Are there reasons a higher minimum wage will not have the textbook effect? Of course. ... But microeconomists are kidding themselves if they think this plethora of plausible explanations makes their branch of economics any more scientific or respectable than standard macroeconomics. ...
