Ej. Balder, Incompatibility of usual conditions for equilibrium existence in continuumeconomies without ordered preferences, J ECON THEO, 93(1), 2000, pp. 110-117
In recent years attempts were made to extend the equilibrium existence resu
lts of Gale and Mas-Colell (1975. J.Math. Econ. 2, 9-15) and Shafer and Son
nenschein (1975, J. Math. Econ. 2, 345-348) to continuum economies. Here it
is shown that the usual conditions used for these attempts force the "pref
erred to" correspondence to be empty-valued almost everywhere on the nonato
mic part of the measure space of agents. Several published continuum extens
ions of the existence results of Shafer and Sonncnschein are thus rendered
pointless. Journal of Economic Literature Classification Number: C72. (C) 2
