live chatConsider a regular run of the mill aggregate demand curve such as the one displayed here Like all aggregate demand curves this one is constructed based on several ceteris paribus aggregate demand determinants such as the size of the money supply 03 01 32 Understanding how aggregate demand is different from demand for a specific good or service Justifications for the aggregate demand curve being downward sloping
live chatSupply and demand models are useful for examining the behavior of one good or market but what about looking at a whole economy Luckily the aggregate supply and aggregate demand model lets us do The aggregate supply of an economy is the amount of goods and services produced at a specific price level measured over a specific time Movements in production costs which include the costs of labor and raw materials have an impact on long term and short term aggregate supply
live chatAggregate demand is an economic measurement of the sum of all final goods and services produced in an economy expressed as the total amount of money exchanged for those goods and servicThe aggregate demand curve is drawn under the assumption that the government holds the supply of money constant One can think of the supply of money as representing the economy s wealth at any moment in time As the price level
live chatNow which factors cause aggregate demand curve to shift We have drawn above aggregate demand curve AD in Fig 221 keeping non price factors such as government expenditure taxes autonomous investment money supply as remaining fixed or constantThe aggregate supply curve depicts the quantity of real GDP that is supplied by the economy at different price levels The reasoning used to construct the aggregate supply curve differs from the reasoning used to construct the supply curves for individual goods and servic
live chatNotice the real money supply on the right hand side is fixed when drawing the LM any change in the real money supply shifts the entire curve Assuming real money demand depends positively on the amount of real transacting Y and negatively on the opportunity cost of holding money r the LM is an upward sloping curve with steepness depending on how sensitive real money demand is to changes If aggregate demand declines unexpectedly say because the money supply grows less quickly the new short run equilibrium will be at point B where the inflation rate is lower and we have a much lower growth rate perhaps even a negative growth rate as shown here
live chatAggregate Demand and Aggregate Supply Section 01 Aggregate Demand As discussed in the previous lesson the aggregate expenditures model is a useful tool in determining the equilibrium level of output in the economy 05 03 32 The aggregate demand and supply model Make sure that you understand the idea of the long run aggregate supply and how to draw a recessionary gap and inflationary gap Keep in mind that the long
