Question 1

The Fisher effect suggests that, in the long run, if the rate of inflation rises from 3 per cent to 7 per cent, the nominal interest rate should increase by 4 percentage points and the real interest rate should remain unchanged.

Accepted Answer

The Fisher effect states that the nominal interest rate should adjust one-for-one with changes in the expected inflation rate, so if inflation increases by 4 percentage points, the nominal interest rate should also increase by 4 percentage points to maintain the same real interest rate.

Question 2

In the long run, the demand for money is most dependent upon the

Accepted Answer

The demand for money is most dependent upon the level of prices in the long run. As prices rise, people need more money to cover their expenses, and therefore demand for money increases. Conversely, as prices fall, people need less money to cover their expenses, and demand for money decreases.

Question 3

Real economic variables measure

Accepted Answer

Real economic variables are adjusted for inflation and are measured in the prices of a base year to reflect true purchasing power.

Question 4

An inflation tax is paid by those that hold money because inflation reduces the value of their money holdings.

Accepted Answer

Inflation reduces the purchasing power of money, meaning that the same amount of money can buy fewer goods and services than before. Those who hold money, such as savers, are directly affected by this reduction in purchasing power and effectively pay an inflation tax.

Question 5

Suppose an economy produces only ice cream cones.If the price level rises, the value of currency

Accepted Answer

When the price level rises, the value of currency falls because one unit of currency is able to buy fewer ice cream cones. This is because the prices of ice cream cones have increased, meaning it takes more units of currency to purchase the same number of cones as before.

Question 6

In the long run, an increase in the money supply tends to have an effect on real variables but no effect on nominal variables.

Accepted Answer

An increase in the money supply tends to have both short-run and long-run effects on both nominal and real variables. In the short run, an increase in the money supply leads to an increase in aggregate demand, which raises both nominal and real output and prices. In the long run, however, an increase in the money supply leads to a corresponding increase in prices (inflation), but has no effect on real variables such as output and employment. Therefore, an increase in the money supply affects both nominal and real variables in the short run and has an effect on nominal variables in the long run.

Question 7

In the long run, inflation is caused by

Accepted Answer

Inflation occurs when the supply of money in an economy exceeds the demand for goods and services. As a result, the value of money falls, causing prices to rise. The most common cause of inflation is when governments print too much money, leading to an oversupply of money in circulation. This oversupply of money reduces the value of money, causing prices to rise. Therefore, option D is the correct answer.

Question 8

If the price level doubles,

Accepted Answer

When the price level doubles, the purchasing power of the currency decreases by half, meaning that the value of money is cut by half. This means that the same amount of money can only buy half the amount of goods and services it could before, leading to inflation. The quantity demanded of money may change, but it depends on various factors such as the interest rate, so option A is not always true. Nominal income may also be affected by inflation, so option C is not true in general. The money supply may or may not change, and it is not tied directly to the price level, so option E is not a certain consequence of a price level change.

Question 9

If inflation turns out to be higher than people expected, wealth is redistributed to lenders from borrowers.

Accepted Answer

The answer of If inflation turns out to be higher...

Question 10

The term hyperinflation refers to

Accepted Answer

Hyperinflation refers to a period of very high inflation, where the prices of goods and services skyrocket and the value of currency rapidly decreases. This often leads to a lack of confidence in the economy and can have devastating effects on the population.

Question 11

When prices rise at an extraordinarily fast rate, it is called

Accepted Answer

When prices rise at an extraordinarily fast rate, it is called hyperinflation. Disinflation refers to a decrease in the inflation rate, deflation refers to a general decrease in the prices of goods and services, and inflation refers to a general increase in the prices of goods and services. Hypoinflation is not a commonly used term in economics.

Question 12

Monetary neutrality means that a change in the money supply doesn't cause a change in anything at all.

Accepted Answer

Monetary neutrality is the idea that changes in the money supply do impact the overall economy, but the extent of that impact is subject to debate.

Question 13

If the price level were to double, the quantity of money demanded would double because people would need twice as much money to cover the same transactions.

Accepted Answer

The answer of If the price level were to double,...

Question 14

The shoeleather costs of inflation should be approximately the same for a medical doctor and for an unemployed worker.

Accepted Answer

The shoeleather costs of inflation are the increased costs of time and effort spent in response to inflation, such as having to go to the bank more often to withdraw smaller amounts of money. These costs are typically higher for individuals with lower incomes and less flexible schedules, such as an unemployed worker. A medical doctor, on the other hand, may have a higher income and more flexible schedule, which may mitigate some of the shoeleather costs of inflation.

Question 15

The supply of money is determined by

Accepted Answer

In South Africa, the supply of money is determined by the South African Reserve Bank. The Bank aims to control inflation and maintain financial stability by regulating the levels of money supply in the economy through various policy tools. The price level, treasury and budget office, and demand for money can all influence the supply of money, but ultimately it is the Reserve Bank that has the authority to control and regulate it.

Question 16

If the nominal interest rate is 7 per cent and the inflation rate is 5 per cent, the real interest rate is 12 per cent.

Accepted Answer

The real interest rate is calculated by subtracting the inflation rate from the nominal interest rate. So, in this case, the real interest rate would be 2% (7% - 5%), not 12%.

Question 17

The quantity theory of money concludes that an increase in the money supply causes a proportional

Accepted Answer

The quantity theory of money states that the level of prices in an economy is directly proportional to the amount of money in circulation. Therefore, an increase in the money supply results in an increase in prices. Choice B is incorrect because the quantity theory of money assumes that the economy is operating at full capacity, so an increase in the money supply does not result in an increase in real output. Choices C, D, and E are also incorrect as they do not reflect the conclusions of the quantity theory of money.

Question 18

If the money supply is R500, real output is 2,500 units, and the average price of a unit of real output is R2, the velocity of money is 10.

Accepted Answer

The equation of exchange is MV = PY, where M is the money supply, V is velocity, P is the average price level, and Y is real output. We can rearrange this equation to solve for velocity:

V = PY/M

Plugging in the given values, we get:

V = (2,500 x R2) / R500
V = 10

Therefore, the statement is true. The velocity of money is 10.

Question 19

Economists agree that

Accepted Answer

Economists agree that high inflation is costly, but they do disagree about the costs of moderate inflation.

Question 20

An increase in the price level is the same as a decrease in the value of money.

Accepted Answer

When the price level increases, it takes more money to purchase the same quantity of goods and services. Therefore, the value of money decreases as the price level increases.
