Upper semi-continuity of the separating equilibrium correspondence

Peter H Huang
1989 Journal of Economic Theory  
We formulate separating equilibria with (many) signals as the set of zeroes of a suitable mapping and show continuity of this mapping for a suitable topolm We prove upper semi-continuity (USC) of the correspondence mapping the set of multidimensional signalling environments into their sets of separating equilibria.
