The number of equilibria of smooth infinite economies
Covarrubias, Enrique - 2011
. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria. …

Global invertibility of excess demand functions
Covarrubias, Enrique - 2013
In this paper we provide necessary and sufficient conditions for the excess demand function of a pure exchange economy to be globally invertible so that there is a unique equilibrium. Indeed, we show that an excess demand function is globally invertible if and only if its Jacobian never vanishes...
