The economics has a big influence on the commercial laws and the economy-related law in today.
Organizational economics(Transaction cost approach), contract economics have in particular a big
influence on the commercial law so far. The economics contributes to development of the law by
offering logical prediction possibility for the reasoning as the vague of the law.
For example, so-called agent theory is fixed in what an economic discussion introduces it into in
the commercial law. We have a meaning in the economics theory by letting you do the analysis tool
in the commercial law wealthily. However, there is one point that you must be careful about. Little
doubt is possible for organizational economics, contract economics influence on law. The model that
is discussed in a area of the law, you must examine whether it is evaluated of organizational
economics, contract economics. You must confirm whether the application does not have the inherent
limitation.
Organizational economics has provided a theoretical background for the system of the legal rules
about a corporation. However, Organizational economics in itself is not a complete economic theory.
In addition, a complete market and the basics called a perfect rational human being that
organizational economics premises are the suppositions that cannot consist. Therefore, a limit of the
interpretation by it can occur.
There is so-called behavioral economics(experimental economics) as the economic theory that
criticize the neoclassical school(microeconomics) recently. The behavioral economics denied a rational
image of a human being(Homo Economicus) that neoclassical school made the premise. The
behavioral economics classified the image of a human being of the irrationality into the field of
vision and was going to take in psychology and a behavioral science in economics. The opinion of
the behavioral economics has an influence on law mainly in U.S.A. and Europe.
It is necessary we receive a new economic theory in the study of the commercial law, and to
solve classic difficult problems well from now on.
