Economists vs politicians: ... I suspect that there is a greater distance now between the political parties and economist than there has been for years. ...
You might think this isn't a wholly bad thing. Many ideas are not worth adopting ... This, however, doesn't justify politicians' lack of interest in the settled, established knowledge that economists do have.
So, where is there such a gap between politicians and economists?
The fault might partly lie with economics. Many academics aren't as interested in closing the gap between academia and the "real world" as they should be. At least some of the discipline was discredited by the crisis, and I get the feeling that there aren't so many good new policy-relevant ideas now.
It might be that the voters are to blame. Maybe they don't want serious politicians who are interested in good ideas but rather, in our narcissistic age, they simply expect their demands to be met, however unreasonable. But is this the whole story? Janan Ganesh thinks not:There is...an unsatisfied demand for seriousness and leadership. Most people do not vote Ukip or parse an MP’s tweet for class meaning. The flight to frivolity in public life is not the voters’ doing. Many are in fact waiting for a leader to arrest it.
This leaves a third suspect - the media. ... Political journalists have been complicit in creating a hyperreal bubble of mediamacro which perpetuates witless ideas (such as conflating the economy with the deficit) to the exclusion of such good ones as might exist.
I'm not sure, then, how exactly to apportion blame for the divorce between politicians and economists. But I do suspect that, net, it is a bad thing.
