értékjelzés

Értékjelzés is a Hungarian term that translates to "value signaling" or "signaling theory" in English. It refers to the concept that individuals or entities may engage in certain behaviors or display specific characteristics not for their intrinsic value, but to convey information about their underlying qualities to others. This signaling is often costly, making it a credible indicator of the trait being communicated.

In economics, értékjelzés is applied to explain phenomena like advertising, educational credentials, and warranties. A company advertising extensively might not solely be about informing consumers about its product, but also about signaling its financial health and commitment to the market. Similarly, obtaining a degree from a prestigious university can signal a person's intelligence and diligence, even if the specific knowledge gained is not directly used in their profession.

In evolutionary biology, értékjelzés is seen in animal courtship displays. Elaborate songs, bright plumage, or complex dances can signal an individual's fitness, health, and genetic quality to potential mates. The energy and resources expended in these displays make them a reliable indicator that cannot be easily faked.

The core principle is that the costliness of the signal ensures its honesty. If a signal were cheap or easy to produce, it would be easily imitated by individuals who do not possess the underlying quality, rendering it meaningless. Therefore, for a signal to be effective in conveying genuine value, it must be sufficiently burdensome to produce.
