  2. Long run and short run - Wikipedia

    en.wikipedia.org/wiki/Long_run_and_short_run

    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 ...

  3. Phillips curve - Wikipedia

    en.wikipedia.org/wiki/Phillips_curve

    This is nothing but a steeper version of the short-run Phillips curve above. Inflation rises as unemployment falls, while this connection is stronger. That is, a low unemployment rate (less than U*) will be associated with a higher inflation rate in the long run than in the short run. This occurs because the actual higher-inflation situation ...

  4. Profit maximization - Wikipedia

    en.wikipedia.org/wiki/Profit_maximization

    The principal difference between short run and long run profit maximization is that in the long run the quantities of all inputs, including physical capital, are choice variables, while in the short run the amount of capital is predetermined by past investment decisions. In either case, there are inputs of labor and raw materials.

  5. Monopolistic competition - Wikipedia

    en.wikipedia.org/wiki/Monopolistic_competition

    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 ...

  6. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    A short-run marginal cost (SRMC) curve graphically represents the relation between marginal (i.e., incremental) cost incurred by a firm in the short-run production of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables ...

  7. IS–LM model - Wikipedia

    en.wikipedia.org/wiki/IS–LM_model

    The IS–LM model shows the relationship between interest rates and output in the short run in a closed economy. The intersection of the "investment–saving" (IS) and "liquidity preference–money supply" (LM) curves illustrates a "general equilibrium" where supposed simultaneous equilibria occur in both the goods and the money markets.

  8. Marshall–Lerner condition - Wikipedia

    en.wikipedia.org/wiki/Marshall–Lerner_condition

    If the long-run export and import elasticities equal .5 and -.5, exports will rise 5% to $63 million and imports will fall 5% to $104.5 million. The long-run result is a trade deficit of $41.5 million, smaller than the short-run deficit but bigger than the original deficit of $40 million before the depreciation.

  9. AD–AS model - Wikipedia

    en.wikipedia.org/wiki/AD–AS_model

    The AD–AS or aggregate demand–aggregate supply model (also known as the aggregate supply–aggregate demand or AS–AD model) is a widely used macroeconomic model that explains short-run and long-run economic changes through the relationship of aggregate demand (AD) and aggregate supply (AS) in a diagram.
