18. Ross Starr 教授が語る含意
• [The Uzawa Equivalence Theorem] says that use of the
Brouwer Fixed-Point Theorem is not merely one way to
prove the existence of equilibrium. In a fundamental sense,
it is the only way.
• Any alternative proof of existence will include, inter alia, an
implicit proof of the Brouwer Theorem. Hence, this
mathematical method is essential; one cannot pursue this
branch of economics without the Brouwer Theorem.
• If Walras (1874) provided an incomplete proof of existence
of equilibrium, it was in part because the necessary
mathematics was not yet available.

47. コミュニティによるコモンズの統治
• Both state control and
privatization of resources have
been advocated, but neither the
state nor the market have been
uniformly successful in solving
common pool resource problems.
• In contrast to the proposition of
the tragedy of the commons
argument, common pool
problems sometimes are solved
by voluntary organizations rather
than by a coercive state.
