Say's law

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 1034:) by showing that supply and investment were not independent of one another and thus could not be related uniquely in terms of the balancing of disutility and utility. 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? 135: 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 1020:, take the fact that a commodity–commodity economy is substantially altered once it becomes a commodity–money–commodity economy, or once money becomes not only a facilitator of exchange (its only function in marginalist theory) but also a store of value and a means of payment. 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. 459:
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. 1038:
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).

However, Keynes and others argued that hoarding decisions are made by different people and for different reasons than are decisions to dis-hoard, so that hoarding and dis-hoarding are unlikely to be equal at all times, as indeed they are not. Decreasing demand (consumption) does not necessarily stimulate capital spending (investment). 77: 1313:, could adjust to keep hoarding and dis-hoarding equal, so that Say's law could be maintained, or that prices could simply fall, to prevent a decrease in production. But Keynes argued that to play this role, interest rates would have to fall rapidly, and that there are limits on how quickly and how low they can fall (as in the 236:, there must be unmet demand for another: "If certain goods remain unsold, it is because other goods are not produced." However, according to Petur Jonsson, Say does not claim a general glut cannot occur and in fact acknowledges that they can occur. Say's law has been one of the principal doctrines used to support the 368:

But the only way of getting rid of money is in the purchase of some product or other. Thus the mere circumstance of creation of one product immediately opens a vent for other products.

John Maynard Keynes argued in 1936 that Say's law is simply not true, and that demand, rather than supply, is the key variable that determines the overall level of economic activity. According to Keynes, demand depends on the propensity of individuals to consume and on the propensity of businesses to

According to Say, the only reason to have money is to buy products. It would not be a mistake, in his view, to treat the economy 589:
When more goods are produced by firms than are demanded in certain sectors, the suppliers in those sectors lose revenue as result. This loss of revenue, which would in turn have been used to purchase other goods from other firms, lowers demand for the products of firms in other sectors, causing an

Not only doesn't supply create its own demand; experience since 2008 suggests, if anything, that the reverse is largely true -- specifically, that inadequate demand destroys supply. Economies with persistently weak demand seem to suffer large declines in potential as well as actual

James Mill used Say's law against those who sought to give the economy a boost via unproductive consumption. In his view, consumption destroys wealth, in contrast to production, which is the source of economic growth. The demand for a product determines the price of the product.

The theory that hoarding is a cause of unemployment has been the subject of discussion. Some classical economists suggested that hoarding (increases in money-equivalent holdings) would always be balanced by dis-hoarding. This requires equality of

The Great Depression posed a challenge to Say's law. In the United States, unemployment rose to 25%. The quarter of the labor force that was unemployed constituted a supply of labor for which the demand predicted by Say's law did not exist.

Although hoarding of money was not a direct cause of unemployment in Keynes's theory, his concept of saving was unclear and some readers have filled the gap by assigning to hoarding the role Keynes gave to saving. An early example was
