AD/AS model and Fiscal Policy Flashcards
What is the AD/AS model?
a macroeconomic model which illustrates the relationship between the aggregate levels of expenditure and output(which equals income)
- identifies the point of equilibrium
where AO = AE which determines the
current level of econ activity
What is aggregate demand?
illustrates the total amount of spending by all sectors in the economy at difference price levels AD
= AE
- AD is negatively sloped -> as the general level of prices in the economy increases, total spending in the economy falls
What are the 3 reasons why AD is negatively sloped?
income effect
- open economy effect
- interest rate differential
What are the factors affecting shifts in AD?
C+I+G+(X-M)
2 Factors affecting AD: Consumption
- Income
- interest rates
2 Factors affecting AD: Investment
- interesst rates
- investment sentiment
2 Factors affecting AD: govt
- changes in govt spending
- level of economic activity
2 Factors affecting AD: net exports
-exchange rates
- terms of trade
What is aggregate supply?
illustrates the total amount of output produced by producers at each general price level
- AS curve not infinitely positively sloped
- the economy has a finite amount of resources, therefore cannot increase
“output indefinently”
What is short run aggregate supply curve?
illustrates the ability of producers to increase output in the short term
- output can be increased and will put pressure on prices to rise
8 What are factors affecting SRAS
- price of imports eg capital
- ER (price of imported capital)
- price of oil, wages
- ToT (price of imported capitals)
- supply shocks eg natural disaster
- sales tax
- technology
- productivity
What is long run AS curve
represents the productive capacity of the economy where resources are fully employed -> productive capacity of the economy
- it demonstrates the full employment Ivl of output (NAIRU-non accelerating inflation rate of UE)
- full employment Ivl of output without high inflation
5 Factors affecting LRAS
- investment
- technology
- productivity
- education/efficiency
- changes to workforce
Contraction graph of LRAS/SRAS
- vertical line of LRAS, is where AD and SRAS intersects.
- equilibrium OE/O(FE), PE
- sustainable growth
- stable prices
- full employment at the NAIRU
5 characteristics of Peak graph of LRAS, SRAS
vertical line of LRAS, is left side of equilibrium OE,PE
- high growth, demand pull inflation
- equilibrium O(FE), PE
- creating expansion gap
- operating at a level of output higher than OE (increase inflation)
6 characteristics of Trough graph of LRAS/SRAS
- LRAS right side of OE,PE
- equilibrium PE, O(FE)
-creating contraction gap - trough has lower employment, OE (where we are at) is lower than O(FE)
(where we want to be) - high cyclical UE, low growth
- operating at a level of output lower than OE
3 Notes about lras/sras
- AD = SRAS -> where the economy is
at (macroeconomic equilibrium OE) - LRAS-> where we want to be →>
O(FE) - O(FE) - tells us where we want to be
(full employment level of output)
What are the 3 EPO’s(economic policy objectives), target rate, types.
Full employment (target UE 4%)
- cyclical: follows business cycle
Stable prices (target 2-3% infl rate)
- Demand pull excess demand
- cost push not enough supply
Sustainable growth (target 3.5-4%)
- sources:
- demand factors
-supply factors
- increase efficiency (allocative, dynamic, technical(productive))
AE model to show cyclical UE (full employment) 3 characteristics
- at y(fe) the economy is operating at a full employment level of Y, output where cyclical UE is zero
- fall in AE from AE(fe) to AE(def) creates a stock buildup which results in a decrease in production which reduces demand for resources including creating cyclical (or demand efficient UE)
- economy contracts to Y(def) and economy is now operating at a level of income, output below full employment - creating deflationary gap
AD/AS model to show cyclical UE(full employment) 3 characteristics
- at O(fe)LRAS the economy is operating at a full employment level of output where cyclical UE is zero
- fall in AD from AD to AD1 creates a stock buildup which results in a decrease in production which reduces demand for resources including creating cyclical UE (or demand efficient UE)
- economy contracts to OE1 and economy is now operating at a level of output below full employment - creating deflationary gap
AE model to show demand pull inflation 3 characteristics
- at y(fe) the economy is operating at a full employment level of Y, output where prices are stanle
- rise in AE from AE(fe) to AE(inf) creates a stock rundown which results in a increase in production which increases demand for resources, including labour
- economy expands to Y(inf) and economy is now operating at a level of income, output aove full employment - creating inflationary gap
AD/AS model to show demand pull inflation 3characteristics
- at O(fe)LRAS the economy is operating at a full employment level of output where prices are stable
- rise in AD from AD to AD1 creates a stock rundown which results in a increase in production which increases demand for resources including labour
- economy expands to OE1 and economy is now operating at a level of output above full employment - creating inflationary gap
AD/AS model to show cost push inflation 3characteristics
- at O(fe) LRAS the economy is operating at a full employment level of output where prices are stable
- decrease in AS from SRAS to SRAS1 due to increase in costs of proud, decreasing supply/prod, results in rise from PE to PE1
- economy contracts to OE1 and economy is now operating at a level of output below full employment
AD/AS model to show sustainable growth: demand source 3characteristics
- at O(fe)LRAS the economy is operating at a full employment level of output where growth is sustainable
- rise in AD from AD to AD1 creates a stock rundown which results in a increase in production which increase demand for resources including labour
- economy expands to OE1 and economy is now operating at a level of output above full employment - creating inflationary gap
AE model to show sustainable growth: demand source 3characteristics
- at y(fe) the economy is operating at a full employment level of Y, output where growth is sustainable
- rise in AE from AE(fe) to AE(inf) creates a stock rundown which results in a increase in production which increases demand for resources, including labour
- economy expands to Y(inf) and economy is now operating at a level of income, output above full employment - creating inflationary gap
