History

According to research by Dembe and Boden, the term dates back to the 17th century and was widely used by English insurance companies by the late 19th century. Early usage of the term carried negative connotations, implying
fraud In law, fraud is intentional deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud can violate civil law (e.g., a fraud victim may sue the fraud perpetrator to avoid the fraud or recover monetary compen ...
or immoral behavior (usually on the part of an insured party). Dembe and Boden point out, however, that prominent mathematicians who studied decision-making in the 18th century used "moral" to mean "subjective", which may cloud the true ethical significance in the term. The concept of moral hazard was the subject of renewed study by economists in the 1960s, beginning with economist Ken Arrow, and did not imply immoral behavior or fraud. Economists use this term to describe inefficiencies that can occur when risks are displaced or cannot be fully evaluated, rather than a description of the ethics or morals of the involved parties. Rowell and Connelly offer a detailed description of the genesis of the term moral hazard, by identifying salient changes in economic thought, which are identified within the medieval theological and probability literature. Their paper compares and contrasts the predominantly normative conception of moral hazard found within the insurance-industry literature with the largely positive interpretations found within the economic literature. Often what is described as "moral hazard in the insurance literature is upon closer reading, a description of the closely related concept, adverse selection.

described moral hazard as "any situation in which one person makes the decision about how much risk to take, while someone else bears the cost if things go badly." Financial bailouts of lending institutions by governments, central banks or other institutions can encourage risky lending in the future if those that take the risks come to believe that they will not have to carry the full burden of potential losses. Lending institutions need to take risks by making loans, and the riskiest loans usually have the potential for making the highest return. Taxpayers, depositors, and other creditors often have to shoulder at least part of the burden of risky financial decisions made by lending institutions. Many have argued that certain types of mortgage

contribute to moral hazard. Mortgage securitization enables mortgage originators to pass on the risk that the mortgages they originate might default and not hold the mortgages on their balance sheets and assume the risk. In one kind of mortgage securitization, known as "agency securitizations," default risk is retained by the securitizing agency that buys the mortgages from originators. These agencies thus have an incentive to monitor originators and check loan quality. "Agency securitizations" refer to securitizations by either Ginnie Mae, a government agency, or by

in that the securitizing agency retains default risk. Under both models, investors take on only interest-rate risk, not default risk. In another type of securitization, known as "private label" securitization, default risk is generally not retained by the securitizing entity. Instead, the securitizing entity passes on default risk to investors. The securitizing entity, therefore, has relatively little incentive to monitor originators and maintain loan quality. "Private label" securitization refers to securitizations structured by financial institutions such as investment banks, commercial banks, and non-bank mortgage lenders. During the years leading up to the

of Moody's Analytics described moral hazard as a root cause of the subprime mortgage crisis. He wrote that "the risks inherent in mortgage lending became so widely dispersed that no one was forced to worry about the quality of any single loan. As shaky mortgages were combined, diluting any problems into a larger pool, the incentive for responsibility was undermined." He also wrote, "Finance companies weren't subject to the same regulatory oversight as banks. Taxpayers weren't on the hook if they went belly up re-crisis only their shareholders and other creditors were. Finance companies thus had little to discourage them from growing as aggressively as possible, even if that meant lowering or winking at traditional lending standards." Moral hazard can also occur with borrowers. Borrowers may not act prudently (in the view of the lender) when they invest or spend funds recklessly. For example,
credit card A credit card is a payment card issued to users (cardholders) to enable the cardholder to pay a merchant for goods and services based on the cardholder's accrued debt (i.e., promise to the card issuer to pay them for the amounts plus the ...

and where the risk of each mortgage passed to the next purchaser instead of remaining with the original mortgaging institution. These mortgages and other debt instruments were put into a large pool of debt, and then shares in the pool were sold to many creditors. Thus, there is no one person responsible for verifying that any one particular loan is sound, that the assets securing that one particular loan are worth what they are supposed to be worth, that the borrower responsible for making payments on the loan can read and write the language in which the papers that he/she signed were written, or even that the paperwork exists and is in good order. It has been suggested that this may have caused the subprime mortgage crisis. Brokers, who were not lending their own money, pushed risk onto the lenders. Lenders, who sold mortgages soon after underwriting them, pushed risk onto investors. Investment banks bought mortgages and chopped up mortgage-backed securities into slices, some riskier than others. Investors bought securities and hedged against the risk of default and prepayment, pushing those risks further along. In a purely capitalist scenario, the last one holding the risk (like a game of musical chairs) is the one who faces the potential losses. In the sub-prime crisis, however, national credit authorities (the

Others believe that financial bailouts of lending institutions do not encourage risky lending behavior since there is no guarantee to lending institutions that a bailout will occur. Decreased valuation of a corporation before any bailout would prevent risky, speculative business decisions by executives who fail to conduct proper due diligence in their business transactions.

, an international regulator for the banking sector, noted that the accounting rules ( IFRS # 9 and 13 in particular) leave entities significant discretion in determining financial instrument fair value and identified this discretion as a potential source of moral hazard: “The evidence consistent with accounting discretion as contributing to moral hazard behavior indicates that (additional) prudential valuation requirements may be justified.” Banking regulators have taken actions to limit discretion and reduce valuation risk, i.e. the risk to banks' balance sheets arising from financial instrument valuation uncertainties. A row of regulatory documents has been issued, providing detailed prudential requirements that have many points of contact with the accounting rules and have the indirect effect of curbing the incentives for moral hazard by limiting the discretion left to banks in valuating financial instruments.

, since numerous actors in the financial market may have had an incentive to increase their exposure to risk. In general, there are three ways in which moral hazard may have manifested itself in the lead up to the financial crisis. * Asset managers may have had an incentive to take on more risk when managing other people's money, particularly if they were paid as a percentage of the fund's profits. If they took on more risk, they could expect higher payoff for themselves and were somewhat shielded from losses because they were spending other people's money. Therefore, asset managers may have been in a situation of moral hazard, where they would take on more risk than appropriate for a given client because they didn't bear the cost of failure. * Mortgage loan originators, such as Washington Mutual, may have had an incentive to understate the risk of loans they originated because the loans were often sold to mortgage pools (see mortgage-backed securities). Because loan originators were paid on a per-mortgage basis, they had an incentive to produce as many mortgages as possible, even if they were risky. Because these institutions didn't expect to hold on to the loans until maturity, they could pass on the risk to the buyer of the loans. Therefore, mortgage loan originators may have been in a situation of moral hazard, because they didn't bear the costs of the risky mortgages they were underwriting. * Third, large banks may have believed they were "

. "Too big to fail" banks may have believed they were essentially invincible to failure, thus putting them in a position of moral hazard: they could take on big risks – thus increasing their expected payoff – thinking that the federal government would bail them out in the event of a major failure. Therefore, large banks may have been in a situation of moral hazard, because they didn't bear the costs of a catastrophic collapse. Notably, the

(FCIC), tasked by Congress with investigating the causes of the financial crisis, cited moral hazard as a component of the crisis, arguing that many factors, including deregulation in the derivatives market in 2000, reduced federal oversight, and the potential for government bailout of "too big to fail" institutions all played a role in increasing moral hazard in the years leading up to the collapse. Others have argued that moral hazard could not have played a role in the financial crisis for three main reasons. First, in the event of a catastrophic failure, a government bailout would only come after major losses for the company. So even if a bailout was expected it wouldn't prevent the firm from taking losses. Second, there is some evidence that big banks were not expecting the crisis and thus were not expecting government bailouts, though the FCIC tried hard to contest this idea. Third, some have argued that negative

Insurance industry

Moral hazard has been studied by insurers and academics; such as in the work of
Kenneth Arrow Kenneth Joseph Arrow (23 August 1921 – 21 February 2017) was an American economist, mathematician, writer, and political theorist. He was the joint winner of the Nobel Memorial Prize in Economic Sciences with John Hicks in 1972. In economi ...

industry. Insurance companies worried that protecting their clients from risks (like fire, or car accidents) might encourage those clients to behave in riskier ways (like smoking in bed or not wearing seatbelts). This problem may inefficiently discourage those companies from protecting their clients as much as the clients would like to be protected. Economists argue that the inefficiency results from information asymmetry. If insurance companies could perfectly observe the actions of their clients, they could deny coverage to clients choosing risky actions (like smoking in bed or not wearing seat belts), allowing them to provide thorough protection against risk (fire or accidents) without encouraging risky behavior. However, since insurance companies cannot perfectly observe their clients' actions, they are discouraged from providing the amount of protection that would be provided in a world with perfect information. Economists distinguish moral hazard from adverse selection, another problem that arises in the insurance industry, which is caused by ''hidden information'', rather than ''hidden actions''. The same underlying problem of non-observable actions also affects other contexts besides the insurance industry. It also arises in

: if a financial institution knows it is protected by a lender of last resort, it may make riskier investments than it would in the absence of the protection. In insurance markets, moral hazard occurs when the behavior of the insured party changes in a way that raises costs for the insurer since the insured party no longer bears the full costs of that behavior. Because individuals no longer bear the cost of medical services, they have an added incentive to ask for pricier and more elaborate medical service, which would otherwise not be necessary. In those instances, individuals have an incentive to over consume, simply because they no longer bear the full cost of medical services. Two types of behavior can change. One type is the risky behavior itself, resulting in a '' before the event'' moral hazard. Insured parties then behave in a more risky manner, resulting in more negative consequences that the insurer must pay for. For example, after purchasing automobile insurance, some may tend to be less careful about locking the automobile or choose to drive more, thereby increasing the risk of theft or an accident for the insurer. After purchasing fire insurance, some may tend to be less careful about preventing fires (say, by smoking in bed or neglecting to replace the batteries in fire alarms). A further example has been identified in flood risk management in which it is proposed that the possession of insurance undermines efforts to encourage people to integrate flood protection and resilience measures in properties exposed to flooding. A second type of behavior that may change is the reaction to the negative consequences of risk once they have occurred and insurance is provided to cover their costs. That may be called ''ex post'' (after the event) moral hazard. Insured parties then do not behave in a more risky manner that results in more negative consequences, but they ask an insurer to pay for more of the negative consequences from risk as insurance coverage increases. For example, without medical insurance, some may forgo medical treatment due to its costs and simply deal with substandard health. However, after medical insurance becomes available, some may ask an insurance provider to pay for the cost of medical treatment that would not have occurred otherwise. Sometimes moral hazard is so severe that it makes insurance policies impossible. Coinsurance, co-payments, and deductibles reduce the risk of moral hazard by increasing the out-of-pocket spending of consumers, which decreases their incentive to consume. Thus, the insured have a financial incentive to avoid making a claim.


Numerical example

Consider a potential case of moral hazard in the health care market caused by the purchase of health insurance. Assume health care has constant marginal cost of $10 per unit and the individual's demand is given by ''Q'' = 20 − ''P''. Assuming a perfectly competitive market, at equilibrium, the price will be $10 per unit and the individual will consume 10 units of health care. Now, consider the same individual with health insurance. Assume this health insurance makes health care free for the individual. In this case, the individual will have a price of $0 for the health care and thus will consume 20 units. The price will still be $10, but the insurance company would be the one bearing the costs. This example shows numerically how moral hazard could occur with health insurance. The individual consumes more health care than the equilibrium quantity because they don't bear the cost of the additional care.


Economic theory

In economic theory, moral hazard is a situation in which the behavior of one party may change to the detriment of another after the transaction has taken place. For example, a person with insurance against automobile theft may be less cautious about locking their car because the negative consequences of vehicle theft are now (partially) the responsibility of the insurance company. A party makes a decision about how much risk to take, while another party bears the costs if things go badly, and the party insulated from risk behaves differently from how it would if it were fully exposed to the risk. According to
contract theory From a legal point of view, a contract is an institutional arrangement for the way in which resources flow, which defines the various relationships between the parties to a transaction or limits the rights and obligations of the parties. From an ...
, moral hazard results from a situation in which a hidden action occurs. Bengt Holmström said this: Moral hazard can be divided into two types when it involves asymmetric information (or lack of verifiability) of the outcome of a random event. An ''ex ante'' moral hazard is a change in behavior prior to the outcome of the random event, whereas ''ex post'' involves behavior after the outcome. For example, in the case of a health insurance company insuring an individual during a specific time period, the final health of the individual can be thought of as the outcome. The individual taking greater risks during the period would be ex-ante moral hazard whereas lying about a fictitious health problem to defraud the insurance company would be ex post moral hazard. A second example is the case of a bank making a loan to an entrepreneur for a risky business venture. The entrepreneur becoming overly risky would be ex ante moral hazard, but willful default (wrongly claiming the venture failed when it was profitable) is ex post moral hazard. According to Hart and Holmström (1987), moral hazard models can be subdivided in models with hidden action and models with hidden information. In the former case, after the contract has been signed the agent chooses an action (such as an effort level) that cannot be observed by the principal. In the latter case, after the contract has been signed there is a random draw by nature that determines the agent's type (such as his valuation for a good or his costs of effort). In the literature, two reasons have been discussed why moral hazard may imply that the first-best solution (the solution that would be attained under complete information) is not achieved. Firstly, the agent may be risk-averse, so there is a trade-off between providing the agent with incentives and insuring the agent. Secondly, the agent may be risk-neutral but wealth-constrained and so the agent cannot make a payment to the principal and there is a trade-off between providing incentives and minimizing the agent's limited-liability rent. Among the early contributors to the contract-theoretic literature on moral hazard were Oliver Hart and Sanford J. Grossman. In the meantime, the moral hazard model has been extended to the cases of multiple periods and multiple tasks, both with risk-averse and risk-neutral agents. There are also models that combine hidden action and hidden information. Since there is no data on unobservable variables, the contract-theoretic moral hazard model is difficult to test directly, but there have been some successful indirect tests with field data. Direct tests of moral hazard theory are feasible in laboratory settings, using the tools of experimental economics. In such a setup, Hoppe and Schmitz (2018) have corroborated central insights of moral hazard theory.
