AD-AS Model Flashcards
Assumptions
Only one good is being produced/sold in the economy
The model is extremely simplified
Ceteris Paribus-“all else remains equal
Only one event happening at a time/happening in isolation
Macroeconomic equilibrium
If the price level is too high, there is an excess supply of output (unsold stock)- a signal to cut back on production. If price level is below equilibrium, excess demand in the short run (stock run down)- a signal to expand production
Changes
Changes in price level causes movement along the AD/AS curve (not a shift)
Changes in cost of production shifts SRAS
Changes in productive capacity shifts LRAS
Demand Shock
Sudden/Considerable shifts in pattern of spending e.g. crashes in stocks or house prices
Supply shocks
Makes production more difficult, disrupts supply chain and higher COP e.g. change in oil price, natural disasters, war
Shocks
Sometimes a shock would affect both AD and AS. It could be favourable or unfavourable (positive or negative) e.g. global pandemic, war, floods etc
Real living wage
Minimum income necessary for a worker to meet their basic needs.
