ΔY Taxing
Tax Multiplier x Change in Taxes
AD/AS Graph
Shows the entire macroeconomy in short run (current) equilibrium and long run equilibrium. Used to analyze how changes in the economy affect price level, output, and unemployment.
When the LRAS is stagnant the economy is in Long Run Equilibrium, when it shifts to the left the economy is in an Inflationary Gap, and when it shifts to the right the economy is in a Recessionary Gap.
Shifters of AD:
C+I+G+(X-M)
Shifters of SRAS: Anything that would affect an economy's supply
Shifters of LRAS: Anything that would affect an economy's potential output

PPC Graph
Shows a hypothetical economy which produces two goods and the maximum combination of those goods that can be produced if resources are fully utilized
Shifters: The Amount of Resources, The Quality of Resources, and Technology

Phillips Curve Graph
Shows the inverse relation of Unemployment and Inflation in an economy.
Shifters of SRPC: Same as SRAS but in opposite direction
Shifters of LRPC: anything that would shift unemployment
