چکیده
We contrast a standard deterministic signaling game with one where the signal-generating mechanism is stochastic. With stochastic signals a unique equilibrium emerges that involves separation and has intuitive comparative-static properties as the degree of signaling depends on the prior type distribution. With deterministic signals both pooling and separating configurations occur. Laboratory data support the theory: In the stochastic variant, there is more signaling behavior than with deterministic signals, and less frequent types distort their signals relatively more. Moreover, the degree of congruence between equilibrium and subject behavior is greater in stochastic settings compared to deterministic treatments.

Thermal Analysis of Laser Hardening for Different Moving Patterns
Transient thermal field in laser surface hardening treatment of medium carbon steel was analyzed by employing both three-dimensional analytical model and finite element model. In finite element model the laser beam was considered as a moving plane heat flux to establish the temperature rise distribution in the work-piece, while in analytical model laser beam was considered as an internal heat s...
متن کاملMoment bounds for truncated random variables
Given any random variable X ∈ [0,M ] with EX = m1 and EX = m2 fixed, various bounds are derived on the mean and variance of the truncated random variable max(0, X−K) with K > 0 given. The results are motivated by questions associated with European call option. The techniques are based on domination by quadratic functions and change of measures in the unimodal distribution case.

1 Bipartite forbidden subgraphs We have seen the Erdős-Stone theorem which says that given a forbidden subgraph H, the extremal number of edges is ex(n,H) = 2(1−1/(χ(H)−1)+o(1))n. Here, o(1) means a term tending to zero as n → ∞. This basically resolves the question for forbidden subgraphs H of chromatic number at least 3, since then the answer is roughly cn2 for some constant c > 0. However, f...
متن کاملAlmost all C 4 - free graphs have less than ( 1 − ε ) ex ( n , C 4 ) edges
A graph is called H-free if it contains no copy of H. An old result of Kleitman and Winston [12] states that there are 2Θ(n 3/2) C4-free graphs on n vertices. Füredi [8] showed that almost all C4-free graphs of order n have at least c · ex(n, C4) edges for some positive constant c > 0. We prove that there is an ε > 0 such that almost all C4-free graphs have at most (1 − ε) · ex(n, C4) edges. Th...
متن کاملDoes strengthening Collective Action Clauses ( CACs ) help ?
In a model with both issues of sovereign debtor moral hazard and creditor coordination under incomplete information, we show that the resulting conict between ex ante and interim e¢ ciency limits the welfare impact of strengthening CACs. Conditional on default, we show that an interim e¢ cient CAC threshold exists and improving creditor coordination results in welfare gains. However, when ex a...
متن کاملProbabilistic Method & Randomized Algorithms Lecture 7 : - Nets , VC - dimension
Suppose X is a set with some distribution D, and C is a class of boolean functions, each of which has the form F : X → {0, 1}. We can think of each function F as a concept, labeling each point in X as positive (1) or negative (0). The goal is to obtain a small subset S ⊂ X such that for each function F ∈ C, if a large fraction (weighted according to distribution D) of points in X are marked as ...
