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 ...
The first term in the RHS describes short-run impact of change in on , the second term explains long-run gravitation towards the equilibrium relationship between the variables, and the third term reflects random shocks that the system receives (e.g. shocks of consumer confidence that affect consumption). To see how the model works, consider two ...
Only in the short run can a firm in a perfectly competitive market make an economic profit. Economic profit does not occur in perfect competition in long run equilibrium; if it did, there would be an incentive for new firms to enter the industry, aided by a lack of barriers to entry until there was no longer any economic profit.

A short-run monopolistic competition equilibrium graph has the same properties of a monopoly equilibrium graph. Long-run equilibrium of the firm under monopolistic competition. The company still produces where marginal cost and marginal revenue are equal; however, the demand curve (MR and AR) has shifted as other companies entered the market ...
Only after this process has run its course will a new long-run equilibrium be attained in the domestic money market, the currency exchange market, and the goods market. As a result, the foreign exchange market will initially overreact to a monetary change, achieving a new short run equilibrium.
[5]: 266 Under the premise that the price level is flexible in the long run, but sticky or even completely fixed under shorter time horizons, it is usual to distinguish between a long-run and a short-run aggregate supply curve. Whereas the long-run aggregate supply curve (LRAS) is vertical, the short-run aggregate supply curve will have a ...
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]
In the short run (and possibly in the long run), markets may find a temporary equilibrium at a price and quantity that does not correspond with the long-term market-clearing balance. For example, in the theory of " efficiency wages ", a labor market can be in equilibrium above the market-clearing wage since each employer has the incentive to ...
