what are the primary economic objectives?
Economic growth
Low inflation
Low unemployment
Satisfactory current account/Balance of payments
what are some other objectives the gvt may set?
Low government borrowing
Stable exchange rate
Issues of equality
Environment
what are the macroeconomic indicators?
what are injections?
This is an increase of expenditure into the circular flow of income, leading to an increase in aggregate demand (AD). Injections can include:
what are withdrawals?
Withdrawals are a reduction of money in the circular flow, sometimes known as leakages. Withdrawals can include:
factors that effect investment (AD)
Confidence
Animal spirits
Interest rates
Availability of finance
Government regulation
Economic growth
explain the accelerator effect
ECONOMIC GROWTH AND INVESTMENT RELATIONSHIP
The accelerator effect states that investment levels are related to the rate of change of GDP.
what is a demand side shock?
A demand-side shock is an event which causes a sudden fall in AD. It could be due to a variety of factors. For example:
• Global recession/Credit crunch — causing a fall in demand for UK exports
• Fall in house prices, leading to negative wealth effect and falling AD
• Fall in business and consumer confidence due to an event such as a stock
market crash.
what is the multiplier effect?
The multiplier effect occurs when a change in injections causes a bigger final change in real GDP.
multiplier = change in real GDP/change in injections
The multiplier effect is determined by the marginal propensity to consume (MPC).
• The higher the marginal propensity to consume, the bigger the multiplier.
• If consumers received extra money but none of this was spent directly in
the UK, there would be no multiplier effect.
• If consumers have a high marginal propensity to consume, then there will
be bigger knock-on effects throughout the economy.
” Suppose we have a depressed economy with spare capacity and unemployed workers. If the government spends £10 bn on building roads, they will employ workers. Income and spending will rise by £10bn.
what is aggregate supply?
Aggregate supply (AS) is the total productive capacity of the economy. It is the sum of all the individual supply curves for particular goods.
The AS curve shows maximum potential output; there is a strong correlation with a Production Possibility Frontier (PPF) curve from unit 1, which also shows the maximum potential of an economy.
difference between short run and long run AS?
However, it can be important to distinguish between SRAS and LRAS. A rise in oil prices shifts SRAS. Capital investment would affect LRAS.
what are the 2 different economic beliefs about the LRAS?
Different economists have different views about the LRAS.
• On the left, the classical view is that LRAS is inelastic. In this case, a rise in AD will cause inflation in the long run. Economic growth requires LRAS to shift to the right.
• On the right, the Keynesian view is that there can be spare capacity in the long run (e.g. prolonged recession), therefore an increase in AD can cause higher real GDP (if there is spare capacity).
what is a supply side shock?
If there was a rapid rise in oil prices, we would see a supply-side shock to the economy, leading to inflation and lower economic growth.
A supply-side shock could also occur as a result of:
• Rapid devaluation, causing a rise in the price of imported goods
• Rise in the price of commodities, such as food or coffee.
• Powerful trade unions causing a rapid rise in wages.
what are the 5 ways of measuring economic growth?
causes of economic growth in the short run?
Demand-side factors that can increase economic growth could include:
• Lower interest rates — reducing the cost of borrowing and leading to higher investment and higher consumption
• Higher confidence in the economy — encouraging spending and
investment
• Rising exports — from higher growth in other countries.
limits to economic growth in the short run?
what are some factors that could increase LRAS?
what is an output gap?
The output gap is the difference between potential GDP and actual GDP. In the real world, the rate of economic growth is rarely constant. We can have positive and negative output gaps.
what are the types of unemployment?
explain some policies to reduce unemployment?
• However, demand-side policies may cause higher rates of inflation and will not reduce supply-side unemployment, like structural unemployment.
• However, it would cost money, and it may prove difficult for some older workers to retrain in new industries and develop new skills.
• However, benefits in the UK are already quite low; reducing benefits may increase poverty, but will not create any jobs.
• However, demand for labour may be quite inelastic; cutting wages may just make firms more profitable.
• However, subsidies may prove ineffective for encouraging workers to move, because they may be attached to their local community. Also, firms may have a similar reluctance to set up in depressed areas because of a lack of infrastructure.
what are the 3 types of inflation and the target?
how is CPI calculated?
problems of calculating CPI?
explain the relationship between deflation and productivity?
If deflation is caused by a fall in costs and rising productivity, then deflation may be less damaging to the economy. This kind of deflation can also cause rising real GDP.
Another potential benefit of deflation is that your economy may become more internationally competitive, and it could lead to rising exports. It depends whether other countries are also experiencing deflation.
