賽局理論 求貝氏均衡 - 經濟

1. Recall from Section 1.3 that Matching Pennies (a static game of complete

information) has no pure-strategy Nash equilibrium but has one mixed-strategy

Nash equilibrium: each player plays H with probability 1/2

Player2

H T
┌──┬──┐
H │1,-1│-1,1│
Player1 ├──┼──┤
T │-1,1│1,-1│
└──┴──┘

Provide a pure-strategy Bayesian Nash equilibrium of a corresponding game of

incomplete information such that as the incomplete incomplete information

disappears, the player' behavior in the Bayesian Nash equilibrium approaches

their behavior in the mixed-strategy Nash equilibrium in the original game of

complete information.

題目在相簿裡

麻煩幫我解一下這兩題好嗎

第一題我自己的想法是要用Harsanyi轉換，但我不曉得 (T,H) (H，T) 是否需要轉換
第二題我可以畫出樹狀圖，但是後來就不知道要怎麼解了
請大家幫幫我吧 拜託~
