Macroeconomic Equilibrium :: Economics

Macroeconomic EquilibriumIntroductionMacroeconomic equilibrium for an frugality in the slight run isestablished when pile up demand intersects with miserable-run hoard upsupply. At the price train Pe, the aggregate demand for goods and services is fit to the aggregate supply of output. The output and the generalprice direct in the preservation will tend to adjust towards thisequilibrium position.If the price level is overly high, there will be an excess supply ofoutput. If the price level is under equilibrium, there will be excessdemand in the short run. In both situations there should be a processtaking the economy towards the equilibrium level of output.Consider for exemplar a situation where aggregate supply is greaterthan current demand. This will lead to a build up in stocks(inventories) and this sends a signal to producers either to cutprices (to stimulate an accession in demand) or to reduce output so asto reduce the build up of excess stocks. Either way - there is a object for output to move closer to the current level of demand.There may be occasions when in the short run, the economy cannot meetan change magnitude in demand. This is more likely to occur when an economyreaches full-employment of factor resources. In this situation, theaggregate supply curve in the short run becomes increasinglyinelastic.The diagram at a lower place tracks the effect of this. We forecast aggregate demandrising but the economy finds it difficult to raise (expand)production. There is a small increase in concreteistic national output, but themain effect is to put upward pressure on the general price level.Shortages of resources will lead to a general rhytidoplasty in be and prices.Impact of a change in aggregate supplySuppose that increased efficiency and productivity together with lower scuttlebutt cost (e.g. of essential raw materials) causes the short runaggregate supply curve to pouch outwards. (I.e. an increase in supply- assume no solecism in agg regate demand).The diagram below shows what is likely to happen. AS shifts outwardsand a new macroeconomic equilibrium will be established. The pricelevel has fallen and real national output (in equilibrium) hasincreased to Y2.Aggregate supply would shift inwards if there is a mount up in the unitcosts of production in the economy.

For example a sharp rise in global commodity prices.
