" Think of how striking this is. The poor in these studies behave more “rationally.” They are closer in this case to the rational economic ideal, closer to homo economicus. This not only tells us something about poverty; it also tells us something about behavioral economics. That money is valued in relative terms is considered a classic finding in behavioral economics: presumably something that characterizes everyone’s thinking. Yet here we see that scarcity overturns—or at the very least waters down—this classic finding. In fact, scarcity alters many other findings as well. "
