According to the textbooks on risk management, the tools of risk management can be
classified into two types, `ex-ante' and `ex-post' risk management. The former, which is called as
`loss control', is affected before an accident occurs. Installing fire alarms and building
earthquake-proof houses are the good examples of loss control. In contrast, the latter, which is called
as `loss (risk) financing', is affected after an accident occurs. Saving money and purchasing
the insurance are good examples of loss (risk)
financing.
Loss (risk) financing is the essential tool in case of engaging in some risky activities, but
the purpose of that type of risk management is to cover the damages. Thus, the academic
fields in loss (risk) financing have a tendency to not include investigating the effect of
accident experience.
However, in most cases, the persons concerned may be able to get intangible assets
such as skills and knowledge so as to not to relapse the accidents from the past accident
experience. In this situation, the persons may choose to commit the risk activities even if the expected
profit in the short run is negative.
For example, consider the person who wants to become a Certified Public Accountant
(CPA). In many countries including Japan, it is necessary to pass the exam to become a CPA.
However, the CPA exam is very difficult. According to the website of the Financial Services Agency in
Japan, the acceptance rate of the CPA exam in 2008 was
17.1%. From this acceptance rate, only a
small number of people passed the exam at the first chance. In other words, most people failed
the exam and had to try again. |
