Economics
In economics, more precisely in contract theory, signaling describes the idea that one party (frequently known as the agent), conveys some meaningful information about himself to another party (usually known as the principal.) For example, in Michael Spence's famous job-market signaling model, employees signal the level of their skils to employers by acquiring a certain degree of education.
