Information Asymmetry in Contract Theory and Economics

  • Information asymmetry refers to situations where one party in a transaction has more or better information than the other, creating an imbalance of power and potentially causing inefficiencies and market failure.

  • Examples of information asymmetry include adverse selection (when high-risk individuals are more likely to buy insurance), moral hazard (when parties take risks because they are not fully responsible for the consequences of their actions), and monopolies of knowledge (when one party has exclusive access to information).

  • Visualizing information asymmetry with a scale, the side with more or better information has the balance of power in the transaction.

  • Information asymmetry extends beyond economics to non-economic behavior, such as national leaders' incomplete knowledge of each other's armaments, quality of military personnel, or political climate.

  • Information asymmetries are studied in the context of principal-agent problems, where they are a major cause of misinforming and are essential in every communication process.

  • Information asymmetry is in contrast to perfect information, which is a key assumption in neoclassical economics.

  • James A. Mirrlees and William Vickrey received the Nobel Memorial Prize in Economics in 1996 for their "fundamental contributions to the economic theory of incentives under asymmetric information".

  • George Akerlof, Michael Spence, and Joseph E. Stiglitz received the Nobel Prize in 2001 for their "analyses of markets with asymmetric information".

  • The puzzle of information asymmetry has existed for as long as the market itself but remained largely unstudied until the post-WWII period.

  • Akerlof's "Market for Lemons" paper introduced the concept that certain sellers of used cars have more knowledge than buyers, leading to adverse selection.

  • Spence introduced the idea of "signaling" in economics, while Stiglitz expanded upon the ideas of Spence and Akerlof by introducing an economic function of information asymmetry called "screening".

  • The impact of the 2001 Nobel Prize work led to a greater discussion on the topic and the birth of a movement in economics that changed how the field viewed the market forever.

  • Information asymmetry models assume one party possesses information that other parties have no access to, and examples include adverse selection and moral hazard.Understanding Information Asymmetry: Causes, Consequences, and Countermeasures

  • Information asymmetry occurs when some parties have more information about an issue than others.

  • It is considered a major cause of market failure.

  • There are different types of information asymmetry, including adverse selection, moral hazard, and monopolies of knowledge.

  • Countermeasures to reduce information asymmetry include signaling, screening, warranties, mandatory information disclosure, incentives and penalties, and information gathering.

  • Signaling is the transfer of information to the other party to resolve the asymmetry.

  • Screening is the provision of a menu of choices that depend on the private information of the other party.

  • Warranties are utilized as a method of verifying the credibility of a product and are a guarantee issued by the seller promising to replace or repair the good should the quality not be sufficient.

  • Mandatory information disclosure is a regulatory instrument that can reduce information asymmetry.

  • Incentives and penalties can be implemented to reduce moral hazard.

  • Game theory and contract theory provide insights into how various economic agents can enter contractual arrangements in situations of unequal levels of information.

  • Information asymmetry can occur and be maintained in several ways, including media outlets, the educational system, organizational and legal measures, exclusive information networks, and mass surveillance.

  • Information asymmetry can lead to distrust between buyers and sellers, opportunistic behavior, and lower quality provision in markets.Understanding Information Asymmetry: Applications in AI, Management and Online Advertising


  • There is a reduced level of information asymmetry between two artificial intelligent agents than between two human agents.
  • When artificial intelligent agents engage in financial markets, it reduces arbitrage opportunities making markets more efficient.
  • As the number of artificial intelligent agents in the market increase, the volume of trades in the market will decrease.


  • Private information asymmetry within firms influences normal business activities.
  • Different information was an additional source of information asymmetry in venture capitalist and alliance networks.
  • Firms can exploit their informational gap through impression management, decoupling and information concealment.
  • Incentives, precommitment, information intermediaries, and monitoring and reward are some approaches that management can use to address information asymmetry problems.

Online Advertising

  • Online advertising is a dominant form of advertising, and a potential source of information asymmetry.
  • The nature of the internet and prevalence of social media in society has given firms opportunities to create promotional content in a less passive way than other forms of advertising.
  • 'Noise' represents any techniques that are used with the intent of obstructing, altering, or blocking the interpretation of the message by the receiver.
  • Highly advertised and strongly promoted items are generally more likely to be bought by customers, even if the product is inferior to less advertised competition, introducing adverse selection.
  • Online advertising that appears trustworthy but can be malicious in intent can still be trusted by consumers, despite the information asymmetry, even if consumers themselves identify as critical of the medium.
