https://en.wikipedia.org/wiki/Signalling_theoryWithin evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species. The central question is when organisms with conflicting interests, such as in sexual selection, should be expected to provide honest

Xem thêmWhen animals choose mating partners, traits such as signalling are subject to evolutionary pressure. For example, the male gray tree frog, Hyla versicolor, produces a call to attract females. Once a female chooses a mate,

https://en.wikipedia.org/wiki/Signalling_(economics)In contract theory, signalling (or signaling; see spelling differences) is the idea that one party (termed the agent) credibly conveys some information about itself to another party (the principal). Although signalling theory was initially developed by Michael Spencebased on observed knowledge gaps between organisations and prospective employees, its intuitive nature led it to be adapted to many other domains, such as Human Resource Management, business, and financia…

Costly signaling theory in evolutionary psychology - Wikipedia
https://en.wikipedia.org/wiki/Costly_signaling_theory_in_evolutionary_psychologyCostly signaling theory in evolutionary psychology refers to uses of costly signaling theory and adaptationism in explanations for psychological traits and states. Often informed by the closely related fields of human behavioral ecology and cultural evolution, such explanations are predominantly focused on humans and emphasize the benefits of altering the perceptions of …

Railway signalling - Wikipedia
https://en.wikipedia.org/wiki/Railway_signallingRailway signalling ( BE ), also spelled railway signaling ( AE ), is a system used to direct railway traffic and keep trains clear of each other at all times. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and momentum of a train, which makes it difficult to ...
Signaling (telecommunications) - Wikipedia
https://en.wikipedia.org/wiki/Signaling_(telecommunications)In the public switched telephone network (PSTN), in-band signaling is the exchange of call control information within the same physical channel, or within the same frequency band, that the telephone call itself is using. An example is dual-tone multi-frequency signaling (DTMF), which is used on most telephone lines to customer premises.
Signal - Wikipedia
https://en.wikipedia.org/wiki/SignalIn signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The IEEE Transactions on Signal Processing includes audio, video, speech, image, sonar, and radar as examples of signal.

With imperfect information, investors cannot distinguish between high-quality firms and low-quality firms. Hence, high-quality firms choose to underprice their new issues in order to signal their true ...
