Macroeconomics (from the greek prefix makro-meaning large + economics) is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole this includes regional, national, and global economies. The ad–as or aggregate demand–aggregate supply model is a macroeconomic model that explains price level and output through the relationship of aggregate demand and aggregate supply it is based on the theory of john maynard keynes presented in his work the general theory of employment, interest and money. The aggregate demand curve ad remaining constant, with the leftward shift in aggregate supply curve from as 0 to as 1, leads to the new macro-economic equilibrium being established at point t, at which price level is higher and aggregate output smaller than before. If the system is in equilibrium and the as or ad curves shift, we can use the ad curve in conjunction with the as curve to work out what the new equilibrium output and price level will be if the system is not in equilibrium, then the is/lm subsystem or the labor market, or both, are in disequilibrium. Home macro economic notes and essays macro economic essays essay: explain how the natural rate of unemployment is determined the natural or (equilibrium) level of unemployment is determined by calculating the level of unemployment when the labour market is in equilibrium the natural rate of unemployment is shown by the below.
Im a student in south africa, writing an essay on the ad-as model with regard to the walmart acquisition of massmart here in sa we are required to critically analyse the takeover with respect to the impact on south african gdp as well has introduce and explain the as-ad model and link it to the situation. Since aggregate demand is defined as spending on domestic goods and services, export expenditures add to aggregate demand, while import expenditures subtract from aggregate demand two sets of factors can cause shifts in export and import demand: changes in relative growth rates between countries and changes in relative prices between countries. Equilibrium means a state of equality or balance between market demand and supply equilibrium means a state of equality or balance between market demand and supply changes in equilibrium market prices - revision video behavioural economics example essays (volume 1) for a level economics sku: 02-4130-30038-03 printed edition. New-keynesian economics: an as-ad view pierpaolo benigno nber working paper no 14824 march 2009, revised may 2013 jel no e0 abstract a simple new-keynesian model is set out with as-ad graphical analysis.
The ad/as framework implies two ways that inflationary pressures may arise one possible trigger is if aggregate demand continues to shift to the right when the economy is already at or near potential gdp and full employment, thus pushing the macroeconomic equilibrium into the steep portion of the as curve. Equilibrium price and quantity occur where quantity demanded equals quantity supplied or where the downward-sloping demand curve intersects the upward sloping supply curve. Market equilibrium occurs when market supply equals market demand the equilibrium price of a good or service, therefore, is its price when the supply of it equals the demand for it.
Pceconcom class notes by aggregate demand and aggregate supply equilibrium if the aggregate demand, short run aggregate supply and long run aggregate supply all meet at the same point, then the economy is in long run equilibrium. Refer to the sets of the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves use the graphs to explain the process and steps by which each of the following economic scenarios will shift the economy from one long-run macroeconomic equilibrium to another equilibrium.

When as shifts right, then the new equilibrium e1 is at the intersection of ad and as1, and then yet another equilibrium, e2, is at the intersection of ad and as2 shifts in as to the right, lead to a greater level of output and to downward pressure on the price level. The aggregate supply - aggregate demand model the first formal macroeconomics model introduced by the text is called the aggregate supply - aggregate demand model , which will hereafter be referred to as the as/ad model.
