This was a tough, slow read for me. My knowing little about economics probably didn't make it easier. On the other hand, I read about stuff many economists take for granted (but Orlaean doesn't) with fresh eyes. I was amazed to learn that many economists try to get around money and more astounded that many economists try to sidestep the reality of human beings. Now wonder we get economic collapses. Orlaen brings in René Girard & Durkheim to explore economics more anthropologically. Girard's concept of mimetic desire is quite illuminating for how humans handle commodities, money & especially markets. Girard speaks of mimetic desire, imitating the desires of other people as basic to our humanity. If Girard is right, then mimetic desire would have a lot to do with economics. Orlaean demonstrates how social mimetic processes establish currency & also affect pricing of commodities and market shares. Where Girard explores how mimetic desire can lead to good, modelling caring relationships for example, but also, and more famously, where mimetic desire goes bad and leads society into violent meltdowns, Orlaean sees mimetic desire as merely a practical trait that has strong effects on the market. Orlaean's analysis of the crises of 2007-2008 show how a mimetic process swooped through the world and ruined fiances for the next few years. Unfortunately, Orlaean shows no interest in the ethical aspects of money and economy. He occasionally hints at greed possibly being relevant to the financial breakdown but he doesn't bring that in. If we were to apply Girard's thought to economy. ethical questions having to do with violence and sacrificing the more helpless people in society would emerge as important matters. Orlaean has taken a major step in connecting economic theory with actual human beings but other thinkers need to take these insights much further into the human dimensions.
