Walras's law is a consequence of finite budgets. If a consumer spends more on good A then they must spend and therefore demand less of good B, reducing B's price. The sum of the values of excess demands across all markets must equal zero, whether or not the economy is in a general equilibrium.
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]
If the value of the excess demand function is positive, then more units of a commodity are being demanded than can be supplied; there is a shortage. If excess demand is negative, then more units are being supplied than are demanded; there is a glut. The assumption is that the rate of change of prices will be proportional to excess demand, so ...
[3] [6] At each price, the firm must accept the level of output as determined by the market's consumer demand, and every output quantity is identified with a price that is determined by the market's consumer demand. The price and output are co-determined by consumer demand and the firm's production cost structure. [4]
Prices are announced (perhaps by an "auctioneer"), and agents state how much of each good they would like to offer (supply) or purchase (demand). No transactions and no production take place at disequilibrium prices. Instead, prices are lowered for goods with positive prices and excess supply. Prices are raised for goods with excess demand.
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.

Monetary-disequilibrium is a short-run phenomenon as it contains within itself the process by which a new equilibrium is established i.e. through changes in the price level. If the demand for real balances changes, either the nominal money supply or price level can adjust to monetary equilibrium in the long run as seen from the figure. [3]
The rule also implies that, absent menu costs, a monopolistic firm will never choose a point on the inelastic portion of its demand curve. For an equilibrium to exist in a monopoly or in an oligopoly market, the price elasticity of demand must be less than negative one (<), for marginal revenue to be positive. [4]
