How do you evaluate the credibility and reliability of signals and screens?
In game theory, signals and screens are ways of conveying or extracting information from other players in strategic situations. Signals are actions or messages that reveal something about the sender's type, preferences, or intentions. Screens are actions or tests that elicit information from the receiver or filter out unwanted types. But how can you tell if a signal or a screen is credible and reliable? Here are some tips to help you evaluate them.
-
Evaluate cost-benefit dynamics:Compare the costs and benefits for both sender and receiver. For instance, tech companies use coding tests as costly screens to ensure only skilled applicants proceed, enhancing hiring reliability.### *Examine equilibrium strategies:Check if actions align with equilibrium strategies to gauge credibility. A student studying hard is credible if it consistently results in better grades, aligning with academic success goals.
