How to think about uni-disciplinary advice

Tyler Cowen:

Let’s say its 1990, and you are proposing an ambitious privatization plan to an Eastern bloc county, and your plan assumes that the enacting government is able to stay on a non-corrupt path the entire time.

While your plan probably is better than communism, it probably is not a very good plan.  A better plan would take sustainability and political realities into account, and indeed many societies did come up with better plans, for instance the Poland plan was better than the Russia plan.

It would not do to announce “I am just an economist, I do not do politics.”  In fact that attitude is fine, but if you hold it you should not be presenting plans to the central government or discussing your plan on TV.  There are plenty of other useful things for you to do.  Or the uni-disciplinary approach still might be a useful academic contribution, but still displaced and to be kept away from the hands of decision-makers.

Nor would it do to claim “I am just an economist.  The politicians have to figure the rest out.”  They cannot figure the rest out in most cases.  Either stand by your proposed plan or don’t do it.  It is indeed a proposal of some sort, even if you package it with some phony distancing language.

Instead, you should try to blend together the needed disciplines as best you can, consulting others when necessary, an offer the best plan you can, namely the best plan all things considered.
