Installing metal [3] detectors in schools: according to one teacher they'll manage to get the pupils in at about the moment when it is time to break for lunch.

Another rejection [4] of the idea: on principle, not simple empirics. 

Comparative advantage [5] , cooking and satirical argument. Is it really the business of society to iron out the unfair advantages of endowment? 

Comparative macro-economics [6]. Germany has a budget surplus: not a bad thing to have at the beginning of a world-wide (possibly) economic turndown.  Something of a pity that the UK's economy wasn't managed similarly.

It would appear [7] that physicists, when publishing papers, understand markets better than economists do when publishing papers:

believing that it is better to err on the side of letting as many new
ideas in as possible, and to let the market eventually decide what is
good and what is bad through a Darwinian process that selects what is
useful and forgets what is not.
