Signaling games are used to model the following situation: Player 1, the Sender, receives some private information and sends a message m E M to Player 2, the Receiver. The latter, in turn, observes m but not 0, and chooses response r E R. Players'payoffs depend on 0, m and r. What could be simpler? Yet, there is a huge number of economically interesting games that fit nicely within this framework: Spence's job market signaling model is the leading example, but applications abound in IO (limit pricing, disclosure...) finance (security design) and political economics

实验3离散信号的DTFT和DFT 实验目的:加深对离散信号的DTFT和D的及其相互关系的理 解。 实验原理:序列x[n]的DTFT定义:X(e)=x[n]e- n=-∞ N点序列x[n]的DFT定义:

设A是n维酉空间V内的线性变换,如果V内的线性变换A满足a,BV,有 (Aa, B)=(a, B) 则称A是A的共轭变换.A为A的共轭变换当且仅当它们在标准正交基下的矩阵互为共轭 转置. 共轭变换的五条性质: 1)E=E 2)(A)=A 3)(kA)*=kA 4)(A+B)=a+B 5)(AB)'=B'A' 如果A=A,则称A是一个厄米特变换
