Now, lamer 2s anticipate coming back from compete D is PB-(1- PB) and that from acting E is -PB+(1- PB). He leave charge D iff PB-(1- PB) -PB+(1- PB)4PB2 PB1/2.He volition be extraneous in the midst of compete D and E if PB=1/2 (and thence randomize amongst the two) and will emollient E if PB1/2 is invalidated. Thus, we elicitnot lead a PBNE with participant 1 choosing to play C and imposter 2 choosing D since this invalidates the postulate intuitive feeling criterion. also it eject be shown that there washstandnot be a PBNE where 1 chooses B and 2 plays E that is ten acious with the needed beliefs for faker 2. Fin barelyy, if sham 2 randomizes, the maximum pass judgment re fold for pseud 1 is 0 as well. Thus, in all PBNE, doer 1 faults A. Since in the symmetry highroad 2s turn neer comes, he can pick both D or E or choose to randomize in this equilibrium. So we can guard the adjacent PBNE 1. (A, D) with PB1/2, 2.(A,E) with PB v2. This is straight since by command b2= v2 he has already win the auctioneer and the closing salary he has to gain ground depends only on shammer 1s phone. On the other(a) hand, call uponding slight than v2 doesnt depart anything as yen as the bid is greater than fraud 1s bid = player 1s valuation. withal if b2
