Say's law states that "The more goods [for which there is demand] that are produced, the more those goods (supply) can constitute a demand for other goods". Keynes summarized this "law" as asserting that "supply creates its own demand". The consumer's desire to trade causes the potential consumer to become a producer to create goods that can be ...
In microeconomics, excess demand, also known as shortage, is a phenomenon where the demand for goods and services exceeds that which the firms can produce.. In microeconomics, an excess demand function is a function expressing excess demand for a product—the excess of quantity demanded over quantity supplied—in terms of the product's price and possibly other determinants.

Difference between supply and demand Unemployed men queue outside a depression soup kitchen in United States during the Great Depression. A 2014 image of product shortages in Venezuela. In economics, a shortage or excess demand is a situation in which the demand for a product or service exceeds its supply in a market.
Say further argued that because production necessarily creates demand, a "general glut" of unsold goods of all kinds is impossible. If there is an excess supply of one good, there must be a shortage of another: "The superabundance of goods of one description arises from the deficiency of goods of another description." [11]
For example, when there is excess supply in the labor market—that is, unemployment—consumer-laborers will be constrained in their disposable income and hence will demand a smaller quantity of goods at any given price. This diminished goods demand resulting from a constraint in another market is known as the effective demand for goods.
With respect to related goods, when the price of a good (e.g. a hamburger) rises, the demand curve for substitute goods (e.g. chicken) shifts out, while the demand curve for complementary goods (e.g. ketchup) shifts in (i.e. there is more demand for substitute goods as they become more attractive in terms of value for money, while demand for ...
And yet another progressive economic study, this time from the Groundwork Collaborative, sheds light on the problem, arguing that more than half of the consumer price price increases in the middle ...
Supply is fixed for a one-time sale of goods, so the market-clearing price is simply the maximum price at which all items can be sold. In a market where goods are produced and sold on an ongoing basis, the theory predicts that the market will move toward a price where the quantity supplied in a broad period of time will equal the quantity demanded.
