"The economics of anarchy is an important area of research in public choice."
I haven't had the chance to read the whole paper yet, but the abstract for Benjamin Powell and Edward Peter Stringham's "Public Choice and the Economic Analysis of Anarchy" sounds mighty interesting:
Following the lead of the early public choice economists, many current economists are researching and analyzing how individuals interact without government. From their non-public-interested explanations of the creation of government law enforcement to their historical studies of attempts to internalize externalities under anarchy, public choice scholars are arriving at a more realistic perspective on government and how people interact when government law enforcement is lacking. Although the economics of politics often receives more attention, the economics of anarchy is an important area of research in public choice.
