Capitalism and trust

A contributor to the Guardian blog working in the field of "neuroeconomics" (?), Paul J. Zak, has an interesting post about the moral dimensions of capitalism. Not a contradiction in terms, he argues.

Zak points out that a market economy relies on a certain web of trust:

[The] decentralized delivery of goods relies on employees working for two weeks before receiving a pay cheque, companies offering each other lines of credit, and banks offering bridge loans.

Furthermore, Zak says, there are biochemical reasons, or at least incentives, that kick in an a capitalist transaction: "We have found that trust causes a spike in oxytocin and begets reciprocation -- the sharing of money. We are 'wired' to cooperate, and we find it rewarding in the same way that our brains identify eating a good meal or sex as rewarding."

Occasionally, about 2% of the time, you run across someone who doesn't provide trust in return for trust, a freeloader. "The technical term in my lab for these people is 'bastards.'"
