ABSTRACT
A degree in economics bears a striking resemblance with a course on still photography, without of course the aesthetic pleasure afforded by the latter. Indeed, studying economics at university translates into spending years studying … ‘stills’. Every single model in the microeconomics textbook is a series of snapshots of homo economicus, frozen in time, working out which of his choices, that do not violate some exogenous constraint, corresponds to maximum intertemporal utility.
