Abstract: | AbstractJohn R. Commons thought that prices should be stable and that the law of supply and demand should be controlled by the power of the state through patent law and by protecting bargaining equality. Commons also thought that prices should be stabilized by macro monetary policy. These means would allow the realization of a “reasonable price.” Commons called the objective and measurable value in money, which is determined by a court ruling, “reasonable value.” Analysis of Commons’s price and business cycle theories point toward the realization of both “reasonable price” and “reasonable value” and toward “reasonable capitalism” that can replace banker capitalism. |
