AS And Supply Side Pilicies Flashcards
Productivity
Output per unit of factor input
Aggregate supply
Total volume of gode and services that all firms in an economy are willing to supply at any given price
Labour productivity
Output per worker
Why is SRAS curved?
To reflect varying price elasticity of supply in the short run
When economy is operating well short of full capacity it is relatively easy for firms to respond to an increase in the price level
Why does SRAS become vertical?
When economy is closer to full capacity firms are unable to respond quickly to an increase in the price level - respond in elasticity as majority of labour is already being employed, those left unemployed are least productive / skilled , capital is working at full capacity and there is no excess stock
Factors affecting SRAS (5)
1) CHANGES IN LABOUR COSTS:a change in wage rates will shift SRAS curve ( LRAS remains constant) -cheaper wages decrease the production costs of firms and so SRAS shifts outwards - rise in wages would cause inward shift and cost push inflation
2) COMMODITY PRICES: changes to raw material costs and other components will affect firms costs and shift SRAS inwards or outwards accordingly ; as a large proportion of commodities is imported changes in prices will also affect AD
3) EXCHANGE RATE: costs may be affected by changes in exchange rate - fall in exchange rate increases import costs shifting SRAS inwards
4) GOV TAXATION & SUBSIDIES:
5) GLOBALISATION & IMPORT PRICE: availability of cheaper component imports will shift SRAS out while imposition of tariff/ import quota will reduce supply available at each price level
Factors affecting LRAS (5)
1) CHANGES TO LABOUR SUPPLY: any in change in size of workforce will impact LRAS - membership in eu + ( relaxed immigration requirements for non eu citizens) = influx of migrants shifting LRAS out, increasing retirements age will increase workforce size & shift LRAS out, fall in birth rates
2) LABOUR PRODUCTIVITY: improvements in education, training, human resource management can all result in improvement in labour productivity & LRAS shifts out ( however initial effect of increased gov spending will expand AD and LRAS will only shift after time lag)
3) IMPROVEMENTS TO LABOUR MOBILITY: policies that help improve labour mobility will shift LRAS out
4) INCREASE IN QUANTITY/ QUALITY OF CAPITAL STOCK: increase in capital stock of economy shifts LRAS out
5) INCREASING COMPETITION+ EFFICIENCY : deregulation of markets , allowing businesses to set up more easily, removal of bureaucracy , establishing enterprise zones
6) STIMULATE INVENTION+ INNOVATION
Supply side policies
Macroeconomic policies designed to imported supply side potential of economy ( shifting LRAS out) to make markets and industries operate more efficiently and contribute to a faster underlying rate of growth of real national output - POSSIBLE TO GENERATE ECON GROWTH WITHOUT INFLATION
Supply side objectives (6)
1) IMPROVE WOKR INCENTIVES- cut income tax, reduce unemployment benefits and invest in skill development ( training job centres) to help unemployed find work
2) INCREASE LABOUR PRODUCTIVITY-investment in education, training, capital goods to make workforce more productive
3) INCREASE CAPITAL PRODUCTIVITY- attracting foreign investment + encouraging innovation, research, development
4) INCREASE OCCUPATIONAL + GEOGRAPHICAL MOBILITY OF LABOUR
5) PROMOTING MORE COMPETITION - blocking mergers and removing trade barriers
6) ENCOURAGE START UP- establishing enterprise zones where it is cheaper for new for new businesses to set up
Free market approach (5)
1) Cut gov spending& taxes to reduce burdens on private sector
2) introduce laws to limit trade union powers and improve flexibility of labour market ( firing + hiring)
3) Keep gov intervention to minimum to avoid failure ( dissolving quangos, gov agencies
4) Tough competition laws aimed at improving efficiency and international competitiveness
5) Laws to protect intellectual property ( patents, copyrights- increase incentive to invest + innovate
Interventionist approach (4)
1) State has key role in investing in public services & building critical infrastructure for long run economic benefits ( education, infrastructure)
2) Tax incentives & welfare reforms encourage more people to work
3) Regional policy to boost under performing areas / areas of high unemployment
4) controlling international trade to allow does tic industries to expand
Supply side policies and recession
1) reduction in business taxation
2) improving quality of and access to education and training for all-when coming out of recession new jobs may be in different industries to before recession and so this is needed to prevent cyclical unemployment from turning into structural unemployment
3) stimulation of business start ups
Evaluation of supply side policies
1) TIME LAGS:
2) EXPENSE: opportunity cost- paying down deficit/ debt
3) EQUALITY: some policies have adverse effects on income distribution - widening income gap, more poverty, increase of Gini coefficient
4) AD- supply side policies assume sufficient level of. AD
Measuring productivity- output per worker
= real GVA \ number of workers employed
Output per job
= real GVA/ number of jobs
