Watching Watchmen (my Watchmen review here) recently reminded me of a theme of Batman (at least of the higher brow batman) found in Miller's Dark Knight Returns, and the more recent movie version, The Dark Knight, is that Batman "creates" his enemies. In Miller's Dark Knight Returns, it was a post-modern form of creation, a Hegelian thesis creating its antithesis (this was in the heyday of post-modernism, when people believed that the rules of literature could somehow be applied to reality). In Burton's film, it was a literal creation, Batman, dropped Jack Nicholson into a vat of chemicals, that turned him into the Joker. In the recent movie with Heath Ledger, it was somewhere in between, less literal, but also less literary, more sociological perhaps.
But I was wondering, could we have an economic theory of super villains. What would happen in our society if a super hero suddenly showed up. Can we think about this, Gary Becker Economics of Crimes and Punishments style. In some sense, a Batman, would effectively massively up the productivity of crime fighting technology, putting most crooks out of business. Essentially, by shifting up, the marginal cost of crime, Batman reduces the quantity of crime, but that also increases the marginal benefit of crime. Then, it becomes quite plausible that if the payoff to crime has gone up, the impact of Batman will cause talented people in other fields to shift professions, to take advantage of the high marginal benefits. Thus creating supervillains, villains who would have stayed out of crime before because the competition with the small time crooks kept profits in the crime industry too low.
This makes us wonder if it is possible then, that Batman actually makes crime worse. In a static world no. We are still at a low equilibrium for the quantity of crime. However, if talented people (who would otherwise have been at hedge funds or something) have now shifted to crime, and find that they are exceptionally good at it, thereby shifting the MB curve out, or the MC curve in, then maybe Batman can make things worse.
