Overview
Trust is a multifaceted concept that permeates various fields such as economics, finance, and social sciences. This entry explores the different dimensions of “trust,” including its role in game theory, finance (trust funds), and its connotation in regulatory contexts (antitrust).
Historical Context
Trust in Economics and Game Theory: Historically, trust has played a crucial role in economics, particularly in understanding markets with asymmetric information. Notable work includes George Akerlof’s “The Market for Lemons” (1970), which examined the dynamics of trust in markets with information asymmetry.
Trust Funds: The concept of trust funds dates back to the early common law era, evolving significantly during the 19th century with the establishment of legal standards governing trust funds.
Antitrust: The term originated in the late 19th century during the era of industrial consolidation in the United States. The Sherman Antitrust Act of 1890 was one of the first measures implemented to combat monopolistic practices.
Types and Categories

- Static Games: Trust issues often arise in single-shot games where equilibrium with trust might not exist.

Detailed Explanations
Trust in Economics and Game Theory
In game theory, trust is critical in environments of asymmetric information. One prominent example is in markets where sellers know more about product quality than buyers. Trust equilibrium can arise in infinitely repeated non-cooperative games through strategies like tit-for-tat or grim trigger.
Mathematical Model for Trigger Strategies:
Payoff = Σ (β^t * P_t)
Where:
β = discount factor
P_t = payoff in period t
