Competitive equilibrium, economic equilibrium when all buyers and sellers are small relative to the market; Economic equilibrium, a condition in economics; Equilibrium price, the price at which quantity supplied equals quantity demanded; General equilibrium theory, a branch of theoretical microeconomics that studies multiple individual markets
Using the temporary equilibrium method, it can be reduced to a system involving only state variable. This is possible because each short-run equilibrium price will be a function of the prevailing capacity, and the change of capacity will be determined by the prevailing price. Hence the change of capacity will be determined by the prevailing ...
The transition from the short-run to the long-run may be done by considering some short-run equilibrium that is also a long-run equilibrium as to supply and demand, then comparing that state against a new short-run and long-run equilibrium state from a change that disturbs equilibrium, say in the sales-tax rate, tracing out the short-run ...
We will also see similar behaviour in price when there is a change in the supply schedule, occurring through technological changes, or through changes in business costs. An increase in technological usage or know-how or a decrease in costs would have the effect of increasing the quantity supplied at each price, thus reducing the equilibrium price.
where > 0 is the speed of adjustment parameter and is the time derivative of the price — that is, it denotes how fast and in what direction the price changes. By stability theory , P will converge to its equilibrium value if and only if the derivative d ( d P / d t ) d P {\displaystyle {\frac {d(dP/dt)}{dP}}} is negative.
This is opposed to a partial equilibrium, where price levels are taken as given and only output levels are determined within the model economy. Equilibrium: In accordance with Léon Walras's General Competitive Equilibrium Theory, the model captures the interaction between policy actions and behaviour of agents. [6]
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.
Calculating option prices, and their "Greeks", i.e. sensitivities, combines: (i) a model of the underlying price behavior, or "process" - i.e. the asset pricing model selected, with its parameters having been calibrated to observed prices; and (ii) a mathematical method which returns the premium (or sensitivity) as the expected value of option ...
