Abstract

This paper is a supplement to Ghossoub [11]. In this supplement, some of the results of Ghossoub [11], as well as the techniques used to obtain these result are extended to a more general problem of demand for contingent claims with belief heterogeneity. Moreover, a general problem of monotone comparative statics under heterogeneous uncertainty is examined, and I show how the idea of vigilance can be used to obtain a monotone comparative statics result in this case.
