The role of asymmetric information

Definition of asymmetric information: This is a situation where there is imperfect knowledge. In particular, it occurs where one party has different information to another. A good example is when selling a car, the owner is likely to have full knowledge about its service history and its likelihood to break-down.

The potential buyer, by contrast, will be in the dark and he may not be able to trust the car salesman. Asymmetric information can lead to adverse selectionincomplete markets and is a type of market failure. When looking at a car, a buyer can only see the externals and cannot know how reliable the engine is. Asymmetric information is a problem in financial markets such as borrowing and lending.

In these markets, the borrower has much better information about his financial state than the lender. The lender has difficulty knowing whether it is likely the borrower will default. To some extent, the lender will try to overcome this by looking at past credit history and evidence of a reliable salary. However, this only gives limited information.

The consequence is that lenders will charge higher rates to compensate for the risk. Another example of asymmetric information is about insurance. When insuring a good, the insurer is uncertain how well the customer will look after a piece of property. For example, if a consumer was careless with locking his bike, the insurer would not want to insure it.

This problem can lead to the related problem of adverse selection. The employer can look at his CV and past references, but once employed he cannot guarantee the attitude of the worker. Managers of companies may have inside knowledge about the fortunes of the company. With this knowledge, they may know the share of the company is either over-valued or under-valued — compared to market price.

People hold back selling good cars because the equilibrium price is lower than real value of their good car. Asymmetric information can also be analysed with game theory. For example, when deciding whether to cut or increase prices, firms will be uncertain about how their rivals will behave and react. They will have to make decisions while trying to second guess how other second-hand will respond. Some economists argue that the internet has helped to reduce the incidence of asymmetric information.

For example, when guests go to visit hotels and restaurants — they can look at online reviews to have a better idea of what to expect. Selling second-hand goods through market places like Ebay relies on sellers building up good reviews.

Therefore, there is an incentive to only sell goods which are correctly marketed.

Asymmetric information in insurance Another example of asymmetric information is about insurance.

Asymmetric information in share dealing Managers of companies may have inside knowledge about the fortunes of the company. Overcoming Asymmetric information Invest in the business — give signals. With second-hand car markets, if you were buying from a one-off private buyer, you would have reasons to be suspicious about the quality of the car. However, if a second-hand car dealer invests in a large property and advertising, it is a signal that the firm intends to stay in the long-term.

In this case, the firm has a greater incentive to sell reliable cars and avoid costs to its reputation. This is why the price of a second-hand car from big dealers is higher than from private seller.

Give warranties. Another way to avoid asymmetric information is for second-hand car salesmen to give warranties for the reliability of their car.Welcome to our series on economic theories that are changing the way we think. Today, Richard Holden explains how asymmetric information — when one party to a transaction knows more about the deal than the other — affects everything from car sales and IPOs, to credit costs and tattoos.

You may not consider yourself an economist but you almost certainly have first hand experience of an aspect of economic theory called asymmetric information. Suppose you are interested in buying a used car. You meet the seller, who seems nice, and you buy it. On the drive home it breaks down. You have no warranty, no recourse, and are pretty annoyed. What happened? Well, the seller, of course, knew a lot more about the car than you did. He knew whether the engine was regularly over-revved, regular maintenance had been performed, if it had been garaged.

After all, there was trade. In a famous paper in titled The Market for Lemonsthe Nobel Prize-winning American economist George Akerlof pointed out how this kind of asymmetric information — where one party to a potential transaction is better informed than the other party — can lead markets to fall apart completely.

Suppose there are two types of sellers: good types and bad types. Good types have good quality cars, say, and bad types have bad ones. And suppose that there are equal numbers of good and bad types. If the car is a good type, buyers are willing to buy.

If it is a bad type, they are not.

Asymmetric Information

What happens in this market? To answer that question, we need to use to logic of equilibrium and think not only about buyers and sellers valuations, but about their beliefs. So, suppose that there is market in which both good and bad types sell their cars. What will buyers believe about the quality of the car they are getting? So they will value it halfway between how they value a high quality car and a low quality car.

And that will be the market clearing price. Low quality sellers are happy with this — they are getting more than their dud car is worth. But high quality sellers are not happy — they are getting less than their car is worth to them. Why would you sell something for less than you value it at? They exit the market.Five the main theories explain why financial intermediaries exist: Delegated monitoring, information production, liquidity transformation, consumption smoothing and commitment mechanisms.

Moral Hazards, Market Failure, And Adverse Selection Asymmetric information arises when two parties have different information, it can result in moral hazards, market failure, and adverse selection. Words: - Pages: 3. Popular Essays. Ready To Get Started? Create Flashcards.The economic theory of asymmetric information was developed in the s and s as a plausible explanation for market failures. The theory proposes that an imbalance of information between buyers and sellers can lead to market failure.

Market failure, to economists, means an inefficient distribution of goods and services in a free market, in which prices are determined by the law of supply and demand. Three economists were particularly influential in developing and writing about the theory of asymmetric information: George AkerlofMichael Spence, and Joseph Stiglitz.

The three shared the Nobel Prize in economics in for their contributions. Akerlof first argued about information asymmetry in a paper entitled "The Market for 'Lemons': Quality Uncertainty and the Market Mechanism. Akerlof uses the colloquial term lemons to refer to bad cars.

He argues that buyers often do not have the information to distinguish a lemon from a good car.

The Theory of Asymmetric Information in Economics

Thus, sellers of good cars cannot get better-than-average market prices for their products. This argument is similar to Gresham's law about money circulation, which argues that poor quality money triumphs over better money. That theory has faced considerable opposition. Michael Spence added to the debate with a paper "Job Market Signaling. That is, the employer cannot be certain of a candidate's productive capabilities. Spence compares the hiring process to a lottery. Real-world market research has called into question the validity of information asymmetry theory.

In this case, Spence identifies the information asymmetries between employers and employees. It was Stiglitz, however, who brought information asymmetry to mainstream acceptance.

Using a theory of market screening, he authored or co-authored several papers, including significant work on asymmetry in the insurance markets.

Asymmetric Information

Through Stiglitz's work, asymmetric information was placed into contained general equilibrium models to describe negative externalities that price out the bottom of markets. For instance, the health insurance premium needed to cover high-risk individuals causes all premiums to rise, forcing low-risk individuals away from their preferred insurance policies. Market research over the years has called into question the existence or the practical duration of asymmetric information causing market failure.

Real-life analysis has been offered by economists including Erik Bond for the truck market, inCawley and Philipson on life insurance, inTabarrok on dating and employment, inand Ibrahimo and Barros on capital structure, in Little positive correlation between insurance and risk occurrence has been observed in real markets, for instance. One possible explanation is that individuals do not usually have expert information about their own risk types, while insurance companies have actuarial life tables and significantly more experience in predicting risk.

Other economists, such as Bryan Caplan at George Mason University, point out that not everyone is in the dark in real markets.

the role of asymmetric information

Insurance companies aggressively seek underwriting services, for example. Caplan also suggests that models based on the ignorance of one party are flawed, given the availability of information from third parties such as Consumer Reports, Underwriters Laboratory, CARFAX, and the credit bureaus.

Economist Robert Murphy suggests that government intervention can prevent prices from accurately reflecting known information, which can cause market failure.Asymmetric information is concerned with the study of various types of decisions with respect to transactions where a party is well informed in comparison to another and examples of such a problem could be a moral hazard, monopolies of knowledge, and adverse selection and it usually extends to non-economical behavior.

For example, used car owners possess more asymmetric information than they disclose while selling their cars. This can create an element of suspicion for the buyers and make it difficult for sellers who want to sell good quality second-hand cars.

Sellers of high-quality goods would gradually exit the market, leaving only an adverse selection of low-quality goods. Gradually, the market for second-hand cars will disappear. Another instance can be while opting for health insurance, the insured party may not disclose information pertaining to past health ailments if any which causes a gap in the information between the insurer and the insured.

This causes asymmetric information problems in the contract. This refers to the process whereby undesired results occur when buyers and sellers have access to different or asymmetric information.

This leads to an imbalance in the price and quantity of goods and services in the market. For e. A situation in which a party will take risks because the cost incurred will not be felt by the party taking the risk. The hazard can occur when the actions of one party may change to the detriment of another after a financial transaction.

In respect of asymmetric information, moral hazards may occur if one party is insulated from risk and holds more asymmetric information about its actions and intentions than the party paying for negative consequences of risk. This solution is of paramount importance which involves creating opportunities for greater access to information to consumers.

It is almost impossible to provide all the information at a time, but sufficient information should be available for the user to make an educated decision. As a result, along with improved customer satisfaction, the overall quality of the product of the commodity can be improved. This paves way for seamless communication and resolves many problems before they arise.

These benefits offer a cushion to consumers against faulty products. This is useful in negotiating the prices as well. Government intervention through policies is very common in case of market imperfection. The doctor principle stands to benefit the most due to asymmetric information by them thereby controlling the health care labor market. Through monopolistic practices, many doctors or health specialists become better off by taking additional payments from the patients.

The government complete the market or strike a balance between the gainers and losers. Normally, this is executed by imposing higher taxes on the doctor and subsidies to receivers of the healthcare. Industries may set a few pre-conditions to be met for providing the goods and services. This ensures offering high-quality products and services in the market. Information asymmetry can be more harmful in case of adverse selection in the market.

For instance, a person with good health conditions is less likely to opt for life insurance as compared to someone who does not have optimum health conditions. A person can do immoral behavior prior to the transaction due to the asymmetric information problem.

For compensating on the unavailable information and to offset the risk of uncertainty, the health insurance company is empowered to increase all their premiums.

It means the riskiest people price out the less risky customers. Sufficient controlling and monitoring are other big challenges for the government. The government should assume responsibilities for intervening all of the aspects in sectors which have information gap problems. Without proper monitoring and controlling, firms may be impacted by various problems executed by illegal beneficiaries.

The government regulations have to be structured and updated in ways through which gaps are minimized and one party is not taking advantage over the other. It has to be combined with strict monitoring and controlling processes. Firms can be subject to severe penalties if minimum industry standards are not set.

Asymmetric Information is a situation whereby there is unequal knowledge between the parties of a transaction resulting in an unusual advantage to the party with additional knowledge. Adverse selection and Moral hazard can result from severe cases of asymmetric information problems.This paper examines the nature of financial crises from a historical perspective using the new and burgeoning literature on asymmetric information and financial structure.

After describing how this literature helps to understand the nature of financial crises, the paper focuses on a historical examination of a series of financial crises in the United States, beginning with the panic of and ending with the stock market crash of October 19, The asymmetric information approach explains the patterns in the data and many features of these crises which are otherwise hard to explain.

It also suggests why financial crises have had such important consequences for the aggregate economy over the past one hundred and fifty years.

This typically manifests when the seller of a good or service possesses greater knowledge than the buyer; however, the reverse dynamic is also possible. Almost all economic transactions involve information asymmetries.

Asymmetric information is the specialization and division of knowledge, as applied to any economic trade. For example, doctors typically know more about medical practices than their patients. After all, physicians have extensive medical school educational backgrounds that their patients generally don't have. This principle equally applies to architects, teacherspolice officers, attorneysengineersfitness instructors, and other trained professionals.

Asymmetric information isn't necessarily a bad thing. In fact, growing asymmetrical information is the desired outcome of a healthy market economy.

As workers strive to become increasingly specialized in their chosen fields, they become more productive, and can consequently provide greater value to workers in other fields. For example, a stockbroker's knowledge is more valuable to a non-investment professional, such as a farmer, who may be interested in confidently trading stocks, to prepare for retirement.

One alternative to ever-expanding asymmetric information is for workers to study all fields, rather than specialize in fields where they can provide the most value.

However, this is an impractical solution, with high opportunity costs and potentially lower aggregate outputs, which would lower standards of living.

Another alternative to asymmetric information is to make information abundantly and inexpensively available through the internet and other data sources. In some circumstances, asymmetric information may have near fraudulent consequences, such as adverse selectionwhich describes a phenomenon where an insurance company encounters the probability of extreme loss due to a risk that was not divulged at the time of a policy's sale. For example, if the insured hides the fact that he's a heavy smoker and frequently engages in dangerous recreational activities, this asymmetrical flow of information constitutes adverse selection and could raise insurance premiums for all customers, forcing the healthy to withdraw.

The solution is for life insurance providers is to perform thorough actuarial work and conduct detailed health screenings, and then charge different premiums to customers based on their honestly-disclosed risk profiles. To prevent abuse of customers or clients by finance specialists, financial markets often rely on reputation mechanisms.

Financial advisors and fund companies that prove to be the most honest and effective stewards of their clients' assets tend to gain clients, while dishonest or ineffective agents tend to lose clients, face legal damages, or both.
