Marx, Keynes and the possibility of crisis
论证马克思与凯恩斯的经济危机理论互补：马克思从货币流通断裂解释危机可能性，凯恩斯从有效需求不足解释危机现实性，两者共同构建资本主义生产的货币理论。
In this article Peter Kenway states that the theories developed by Marx and Keynes to explain the operation of the capitalistic economy complement each other. Due to the existence of money, in Marx the economic crisis is always a possibili ty that may occur when a rupture in the capi tal circuit separates the act of purchasing from the act of selling. This possibilityarises from the anarchy of capitalistic production, its basiccharacteristic, and raises questions on the demand level required in orden to carry it out. Keynes' theory of the effective demand asserts that the crisis occurs when the inflows and outflows of investment do not provide the sufficient aggregated demand to carry out the productoAccording to the author, the common characteristic to both approaches in then, the attempt to build a new monetary theory of capitalistic production, in which the theory of possibility supplements that of effective pemand in the explanation of why money performs an operative role in the production process. In turn, the theory of effective demand supplements the theory of possibili ty to explain the demand level required to carry out the product between the various departments of the economy. Thus, in the analysis by Kenway, Marx and Keynes share the same area regarding the theory of a possibility of a crisis. The theory of reality would be the subject for another analysis.
