The Classification of Risks
The
Classification of Risks
Willett
recognized that risk is commonly used in an ambiguous manner and
sought
to construct a more precise definition. He first proposed to classify risks
in
two categories, economic risks, because their existence is due to participation
in
economic life, and in contrast extra-economic risks, the existence of which is
not
the result of economic activity. He mentioned that such risks may also
affect
economic activity but he was only concerned by economic risk.
Static
and Dynamic Risks
Willett
considered that a fundamental classification of economic risks is based
on
the distinction between static and dynamic losses. A similar classification
was
suggested by Von Mangold between technical and economic losses. 1 I An
alternative
classification was presented by Hardy and distinguished the
followings:
(1) risks of destruction through physical hazard, (2) uncertainties in
the
production process, (3) risks resulting from market changes, (4) risks caused
by
"abnormal" social conduct and, (5) risks arising from the failure to
use
available
knowledge.
Dynamic
risks are those involved in the possibility of dynamic changes.
They
are resulting from changes in the economic conditions such as price levels,
consumers
tastes, saving behavior and technology. They usually benefit the
entire
society in the long run.
Static
risks involve losses that would occur even if there were no changes in
the
economy such as accidents, fires and other perils of nature. These losses are
also
caused by irregular action or mistakes of human beings. They could be the
source
of gain for an individual but usually static losses involve the destruction
of
assets and are not a source of gain for the society.
Pure
and Speculative Risks
The
distinction between pure and speculative risks is usually attributed to
Mowbray.
13 In the first publication of the American Economic Association,
Professor
Emery distinguished risks of production from speculative risks.14
Risks
of production were not defined but speculative risks were "the risks of
price
fluctuations affecting the whole market. "
Speculative
risks describe a situation where there is a possibility of a loss as
well
as a gain. The activities generating such risks are usually undertaken in the
hope
of a gain. Gambling is a good example of a speculative risk. Investments
in
risky assets are vohmtary accepted although price fluctuations can either
benefit
or deprive the owner.
Pure
risks are those that offer only the prospect of a loss. Therefore, perils
of
nature or consequences of human errors are usually only pure risks.
There
are some borderline examples were it is difficult to classify the risk
because
the process is dynamic and the result may be a short term loss which
could
result in a gain in the long term. A strike results in losses for the workers
and
the firm but in fact the outcome is a new labor contract which carries the
prospect
of improved work conditions and/or salaries and higher expected
productivity
and profits for the firm. The consequences of a war can also be
appreciated
in different ways. A nationalization results in the loss of property
due
to a dynamic change in the country but in fact the decision of investment
usually
incorporates a premium for such a risk in the required rate of return on
the
investment.
