Effective Demand, Production Prices, Principle of Effective DemandAbstract
Every economic theory requires an explicit relationship between distribution and its theory production. In fact, the concept of effective demand has been explored by all authors since the classical authors of Political Economy. This concept can only be defined from some definition of supply price, as it is the price that ensures profitable production of goods. Thus, effective demand is the monetary demand that pays the production prices. We contrast the marginalist approach with the surplus approach, highlighting the criticisms made by Sraffa. Therefore, we seek to analyze the theories addressed and point out how they relate the determination of relative prices to production. We conclude that the surplus approach is the only one compatible with different production theories, given the logical inconsistencies of marginalist theory, and the union between classical production prices and the Principle of Effective Demand is essential to overcome the inconsistencies of neoclassical approaches and Say's Law.
