Check out this interesting read on new findings about how humans conceptualize of and are motivated by money.
Basically, humans seem to adhere to two different sets of norms: social and market. When humans even think about money, we tend to abide by market norms. In other words, just the thought of money makes us less likely to cooperate.
So, to what extent do these findings require IPE scholars to change their theoretical models? Do we need to pay more attention to constructivist concerns about how preferences and structures develop? How helpful are rational choice models at explaining a process that, at least at the individual level, doesn't seem at all rational? What do "market norms" of non-cooperation say about the institutions argument? And how much of this is old news, already exhaustively discussed during the emergence of prospect theory?
