Which of the following is an example of expansionary fiscal policy? [1]increase in taxation [2]Increase in government expenditure [3]increase in the VAT rate [4] increase in the money supply

If the rand depreciates against the dollar (1)South Africa export prices in dollar terms will increase (2)the rand price of South African imports will decrease (3)the balance on the current account of the South African balance of payments will improve. (4)the South African rate of inflation will decrease

1. Use a diagram to explain what will happen to the exchange rate between the Rand and the Dollar if South African exports to the United States increased – This question is from page 55 of the study guide. See the solutions on page 58 of the guide 2. With the aid of a diagram, explain what will happen to the exchange rate between the Rand and the Dollar when the demand for dollars increases This question is from page 55 of the study guide. See the solutions on page 58 of the guide

True of false 1.Exports create a supply of foreign exchange while imports constitute a demand for foreign exchange true 2. An increase in SA imports from the united states will give rise to an appreciation of the rand against the Dollar false 3. If American importers buy more SA goods, the supply of dollars in the South African foreign exchange market increases true

The total value of all final goods and services produced in a country during a particular year is called the (1)gross national income (2)gross domestic expenditure. (3)net national income (4)gross domestic product.

Question YearNominal GDPReal GDP a)Calculate the growth rate of nominal gdp between 2008 and %. ( )/150*100 b) Calculate the growth rate of real gdp between 2008 and % c) What do you think the difference in the two figures can be attributed to ?- real gdp has taken into account inflation effects while nominal gdp has not.

YearNominal GDP Real GDP Use the information in the table above to calculate the increase in real GDP between 2001 and %---( )/280*100

YearGDP at current prices (R millions) GDP at constant (2003) prices (R millions) The increase in real GDP growth between 2001 and 2004 is [1] 0.39% [2] 5.67% [3] 39%. [4] 56.7%

True of False if the marginal propensity to consume is ¾, then at an income level (Y) of 100, the induced consumption is 75 True. Induced consumption is cY. Therefore ¾*100=75 If autonomous consumption is 80 and the mpc =4/5, then C=880 at an income level of 1000 true

If aggregate spending exceeds aggregate production in the simple Keynesian model (1)unplanned decreases in inventories will occur (2)inflation will occur (3)aggregate spending will also exceed aggregate demand (4) intended saving will equal intended consumption spending

Autonomous investment means that investment is independent of the (1)cost of capital goods (2)interest rate (3)level of income. (4) expected revenue to be earned from capital goods

In the simple Keynesian model (1)the marginal propensity to consume has no effect on consumers’ ability to save (2)there is an inverse relationship between savings and the level of income (3)induced consumption is a function of the income level (4) the consumption function is made up of an autonomous component only

Calculate the value of the multiplier if 1. MPC= 3/4, /(1-c)=1/(1-3/4)=4 =8/10, =7/ =2/

Using the following information about the closed economy to calculate equilibrium level of income Autonomous consumption expenditure=R100 Investment expenditure=R150 c =7/8 You first calculate the value of the multiplier, then multiply that by the sum of your autonomous components. Therefore y=multiplier*[autonomous consumption plus autonomous investment] Y=8*[ ] Y =2000

Suppose the autonomous consumption is R200 million, the marginal propensity to consume is 5/6 and autonomous investment is R400 million. Calculate the following: a)The multiplier 1/{1-c}=1/[1-5/6]=6 b) The equilibrium level of income 3600

Calculate the impact on equilibrium level of income of an increase in investment spending of R100 million in the economy above. You add the 100 to the previous total of autonomous components and multiply that value by the multiplier. Y=4200

Keynesian with government- government spending We then looked at the impact of adding government spending to the Keynesian model We wanted answers to how the inclusion of government spending impacts on 1. the size of the multiplier----leaves multiplier unchanged 2. autonomous spending-----increases if government spending increases 3. equilibrium level of income------increases if government spending increases

See the attached word document on the impact of introducing government spending.
