Case Study for Supply Side Economy

A new government scheme has been launched today to tackle our sluggish economic growth. 'Business Link' (for more information and research, visit their website) has started a new scheme called 'My New Business' to give advice to potential entrepreneurs. Could this be a potential supply side policy aimed at shifting our LRAS curve rightward?

Read this short article which explains the potential benefits the scheme will bring to our economy. Click here.

Supply Side Economics

Supply side economic policy is a set of government initiatives that aim to improve the economic performance of markets and industries. Policies tend to be more microeconomic because they focus of individual economic agents. Policies aim to:

· Increase competition within markets

· Increase efficiency within markets

· Increase the economy’s potential production – PPF/LRAS (see here for more)

Supply side fiscal policy

· Creating personal incentives to improve economic performance of the supply-side of the economy

· Since 1979, supply-side fiscal policy had been used by Labour and Conservative governments

· Supply-side economists believe that high levels of government spending, taxation and borrowing lead to crowding out (see below) of the public sector.

The intended effects of supply-side policies are shown below:

It is the free market view that supply-side policies should be used to increase efficiency and competition within markets.

Crowding out

Resource crowding out

Assuming there is no spare capacity in the economy and full employment of all resources, resource crowding out is when employing more labour and capital in the public sector sacrifices the use of the same resources by the private sector. Resource crowding out does not happen when there is spare capacity in the economy because government spending can be seen as ‘picking up the slack’ of the private sector. The private sector can be stimulated and crowding in can occur.

Financial crowding out

Increasing taxes to facilitate for high levels of government expenditure reduces the spending power of private sector firms.

Production Possibility Frontier

The PPF curve shows the combination of capital and consumer goods that can be produced within the economy. The PPF curve essentially shows what the economy can produce. See Production Possibility Frontier and Long Run Aggregate Supply for a more detailed view.

Production Possibility Frontier and Long Run Aggregate Supply

The PPF shows the combination of capital and consumer goods that can be produced within the economy. The PPF shows what the economy can produce. If the economy is producing inside the PPF, point X, it is in a recession. Unemployment is high and the economy is not producing at it’s full productive capacity.

When the economy is producing on the PPF, point Y, it IS producing at its full productive capacity. It is also producing on the LRAS curve, point V on the supply/demand diagram. Real national output is YFE and the price level is P1. Full employment of resources has been achieved, which means that the labour force is fully employed, see Word of the Day. The only way to increase output is by increasing investment in capital goods (which increases consumer goods) thereby increasing LRAS. If this happens, economic growth is occurring in the long run. See Word of the Day. LRAS1 moves rightward to LRAS2 and thus SRAS1 shifts rightward to SRAS2. Real national output in the economy has increased from YFE to YFE2. Assuming AD remains unchanged, the price level falls from P1 to P2.

Word of the Day

Full Employment

According to Beveridge's definition, which is perfectly acceptable to use in the exam, full employment is when 3% or less of the labour force is unemployed.

According to the free market definition, full employment occurs when ASL = ADL

Full employment also occurs when the economy is producing on the LRAS curve, see PPF and LRAS. This is because when there is no spare capacity, all workers willing and able to work are working.

It does not mean that all members of the working population are in employment, frictional and structural unemployment is always occurring.
