Signaling theory is an economic concept where one party conveys credible information about their hidden qualities to another party to influence decisions, often in situations of asymmetric information. It explains behaviors like why job applicants might pursue advanced degrees to signal their abilities, and in modern contexts, it's applied to marketing strategies where companies signal product quality through warranties or branding. This theory highlights how signals must be costly and hard to fake to be effective, making it a cornerstone in understanding trust and efficiency in markets.
