Insurance, in law and economics, is a form of risk management primarily used to hedge against the risk of a contingent loss.
Insurance is defined as the equitable transfer of the risk of a potential loss, from one entity to another, in
exchange for a premium.
Insurer, in economics, is the company that sells the
insurance. Insurance rate is a factor used to determine the amount, called the premium, to be charged for a certain amount of insurance coverage. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.
I. Principles of insurance
Commercially insurable risks typically share seven common characteristics. A large number of homogeneous exposure units. The vast majority of insurance policies are provided for individual members of very large classes.
Automobile insurance, for example, covered about 175 million automobiles in the United States in 2004. The existence of a large number of homogeneous exposure units allows insurers to benefit from the so-called “law of large numbers,” which in effect states that as the number of exposure units increases, the actual results are increasingly likely to become close to expected results. There are exceptions to this criterion. Lloyds of London is famous for insuring the life or health of actors, actresses and sports figures. Satellite Launch insurance covers events that are infrequent. Large commercial property policies may insure exceptional properties for which there are no ‘homogeneous’ exposure units. Despite failing on this criterion, many exposures like these are generally considered to be insurable.Definite Loss. The event that gives rise to the loss that is subject to insurance should, at least in principle, take place at a known time, in a known place, and from a known cause. The classic example is death of an insured on a life
insurance policy. Fire, automobile accidents, and worker injuries may all easily meet this criterion. Other types of losses may only be definite in theory. Occupational disease, for instance, may involve prolonged exposure to injurious conditions where no specific time, place or cause is identifiable. Ideally, the time, place and cause of a loss should be clear enough that a reasonable person, with sufficient information, could objectively verify all three elements. Accidental Loss. The event that constitutes the trigger of a claim should be fortuitous, or at least outside the control of the beneficiary of the insurance. The loss should be ‘pure’ in the sense that it results from an event for which there is only the opportunity for cost. Events that contain speculative elements, such as ordinary business risks, are generally not considered insurable. Large Loss. The size of the loss must be meaningful from the perspective of the insured.
Insurance premiums need to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjusting losses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For small losses these latter costs may be several times the size of the expected cost of losses. There is little point in paying such costs unless the protection offered has real value to a buyer. Affordable Premium. If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that anyone will buy insurance, even if on offer. Further, as the accounting profession formally recognizes in financial accounting standards (See FAS 113 for example), the premium cannot be so large that there is not a reasonable chance of a significant loss to the insurer. If there is no such chance of loss, the transaction may have the form of insurance, but not the substance. Calculable Loss. There are two elements that must be at least estimateable, if not formally calculable : the probability of loss and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to do with the ability of a reasonable person in possession of a copy of the insurance policy and a proof of loss associated with a claim presented under that policy to make a reasonably definite and objective evaluation of the amount of the loss recoverable as a result of the claim. Limited risk of catastrophically large losses. The essential risk is often aggregation. If the same event can cause losses to numerous policyholders of the same insurer, the ability of that insurer to issue policies becomes constrained, not by factors surrounding the individual characteristics of a given policyholder, but by the factors surrounding the sum of all policyholders so exposed. Typically, insurers prefer to limit their exposure to a loss from a single event to some small portion of their capital base, on the order of 5%. Where the loss can be aggregated, or an individual policy could produce exceptionally large claims, the capital constraint will restrict an insurers appetite for additional policyholders. The classic example is
earthquake insurance, where the ability of an underwriter to issue a new policy depends on the number and size of the policies that it has already underwritten. Wind insurance in hurricane zones, particularly along coast lines, is another example of this phenomenon. In extreme cases, the aggregation can affect the entire industry, since the combined capital of insurers and reinsurers can be small compared to the needs of potential policyholders in areas exposed to aggregation risk. In commercial fire insurance it is possible to find single properties whose total exposed value is well in excess of any individual insurer’s capital constraint. Such properties are generally shared among several insurers, or are insured by a single insurer who syndicates the risk into the reinsurance market

III. History Of Insurance
Early instances of insurance.—Forms of insurance were known to the Romans and to some extent were practiced among the Collegia. In certain respects these bodies resembled our benefit societies. For example, they provided for burial and also made some form of provision for promotion among the soldiers in their organizations. In reality, then, they were based on the insurance principle since they accepted from their members a certain stipulated sum and in return agreed to perform certain services. Demosthenes describes marine loans made to the ancient Greeks ; we also have record that insurance existed among the Chinese 2500 years ago. In none of these early instances, however, did insurance reach anything like large proportions. In fact, so far as we know, it entirely disappeared, many centuries passing before there was a revival. It is true that certain laws among the Romans governing annuities necessitated a mortality table, but it was, however, for this sole purpose and apparently not in any sense an insurance matter. Present forms of insurance.—The business of insurance is divided into four main branches :
marine insurance,
fire insurance,
life insurance and
casualty insurance. The first three state the form of disaster against which insurance is provided. The fourth—originally accident insurance—includes all forms not embraced in the other three. An idea of the variety of events against which insurance is offered. Marine insurance antedates every other form, its history dating back over seven centuries. It appears to have been practiced in the Mediterranean, and at least one old policy has come down from the thirteenth century, proving that marine insurance was an established practice among the commercial countries of that time. A broad gap exists between that period and the continuous history running back now some four hundred years, but since that time insurance has been an established business among those engaged in maritime adventures.
Fire insurance, the second oldest form to become permanently established, dates from the great London fire of 1666. Life insurance followed a little later, although not until 1760 was a company founded on a modern basisCasualty insurance owes its origin to the application of steam to railway travel; its more common name of accident insurance was due to the fact that the first events to be insured against were those of accidents to the person on a railway journey. It originated in England in the first half of the nineteenth century.
Put basically, allowance enables those who ache a blow or blow to be compensated for the furnishings of their misfortune. The payments appear from a armamentarium of money contributed by all the holders of alone allowance policies. In added words, alone risks are affiliated and shared, with anniversary policyholder authoritative a addition to the accepted fund.
