Abstract: We investigate the origins of identity and the innate proclivity to draw a distinction between "insiders" and "outsiders".We propose an evolutionary explanation: we argue that identity arises because it facilitates survival. In an evolutionary setting we endogenize preferences and demonstrate that the evolutionarily stable preferences fashioned by natural selection would draw a distinction between insiders and outsiders. We then work out the implications of such preferences in two contemporary scenarios, one entailing rent-seeking behavior and the other involving public good provision. Our results are in conformity with empirical evidence.

We gratefully acknowledge the input of Hugh Neary.
