An example of an exchange economy is provided, satisfying all of the a
ssumptions of Dubey and Shubik (1978), for which the trivial Nash equi

From this example, we are led to propose an argument, related to the
intensity of competition, explaining whv there could be no trade at an
equilibrium point. (C) 1998 Academic Press.
