687:(as has been alleged by those who wish to disagree with it), because the key proposition of the law is that no matter how much people save, production is still a possibility, as it is the prerequisite for the attainment of any additional consumption goods. Say's law states that in a market economy, goods and services are produced for exchange with other goods and services—"employment multipliers" therefore arise from production and not exchange alone—and that in the process a sufficient level of real income is created to purchase the economy's entire output, due to the truism that the means of consumption are limited

Second, after Say's law was dealt with and shown to be theoretically inconsistent, there was a gap to be filled. If Say's law was the logic by which we thought financial markets came to a unique position in the long run, and if Say's law were to be discarded, what were the real "rules of the game" of the financial markets? How did they function and remain stable?

1061:. Capitalism, which is interested in value (money as wealth), must create use value. The capitalist has no control over whether or not the value contained in the product is realized through the market mechanism. This gap between production and realization creates the possibility for capitalist crisis, but only if the value of any item is realised through the difference between its cost and final price. As the realization of capital is only possible through a market, Marx criticized other economists, such as

What this means is that money can be (and must be) hoarded: it may not re-enter the circulatory process for some time, and thus a general glut is not only possible but, to the extent that money is not rapidly turned over, probable.

changing economic circumstances, households and businesses in aggregate seek to increase net savings and thus decrease net debt. To increase net savings requires earning more than is spent—contrary to Say's law, which postulates that supply (sales, earning income) equals demand (purchases, requiring spending). Keynesian economists argue that the failure of Say's law, through an increased demand for monetary holdings, can result in a general glut due to falling demand for goods and services.
1317:, where interest rates approach zero and cannot fall further). To Keynes, in the short run, interest rates are determined more by the supply and demand for money than by saving and investment. Before interest rates can adjust sufficiently, excessive hoarding causes the vicious circle of falling aggregate production (recession). The recession itself lowers incomes so that hoarding (and saving) and dis-hoarding (and real investment) can reach a state of balance below full employment.

others' behavior, and so on. Without Say's law keeping them in balance, financial markets are thus inherently unstable. Through this identification, Keynes deduced the consequences for the macroeconomy of long-run equilibrium being attained not at only one unique position that represented a "Pareto Optima" (a special case), but through a possible range of many equilibria that could significantly under-employ human and natural resources (the general case).
