Question 1

An increase in money demand will raise the equilibrium interest rate in the money market, holding all things constant.

Accepted Answer

An increase in money demand means people want to hold more money, which will drive up the demand for money and decrease the supply of money. This will lead to an increase in the equilibrium interest rate in the money market.

Question 2

In the long run, the interest rate adjusts to balance the supply and demand for money, whereas in the short run, the interest rate adjusts to balance national saving and desired investment.

Accepted Answer

In the long run, the interest rate adjusts to balance national saving and desired investment, whereas in the short run, it can be influenced by monetary policy and the supply and demand for money.

Question 3

The quantity of money demanded is _____ the interest rate.

Accepted Answer

As the interest rate increases, the cost of borrowing money increases, and individuals and firms will demand less money. Therefore, there is an inverse relationship between the quantity of money demanded and the interest rate.

Question 4

According to the theory of liquidity preference, the money demand curve is downward sloping, reflecting _____.

Accepted Answer

The theory of liquidity preference suggests that individuals hold money as a store of value to meet unexpected or emergency expenses. However, holding money incurs an opportunity cost in terms of foregone interest or potential returns from alternative investments. Therefore, the money demand curve slopes downward as people are willing to hold less money as the interest rate increases, which represents the opportunity cost of holding money.

Question 5

When the government increases its purchases, the increase in aggregate demand could be more than or less than the increase in government purchases, depending on whether the multiplier effect or the crowding-out effect is larger.

Accepted Answer

The multiplier effect occurs when the increase in government purchases leads to an even larger increase in aggregate demand through a chain reaction of increased spending and income. This can be greater than the initial increase in government purchases. On the other hand, the crowding-out effect occurs when the government's increased borrowing to finance its purchases leads to higher interest rates, causing a reduction in private investment and consumption, and therefore a smaller overall increase in aggregate demand. Which effect is larger depends on various factors, such as the state of the economy and the magnitude of the initial increase in government purchases.

Question 6

Any change in government spending has a multiplier effect on the level of economic activity.

Accepted Answer

Changes in government spending have a multiplier effect on the economy because they affect income, consumption, and investment. When the government spends more money, it injects more funds into the economy, increasing aggregate demand and stimulating economic activity. The opposite is true when the government reduces its spending, which can lead to a decrease in economic activity. The size of the multiplier effect depends on the marginal propensity to consume (MPC) and the marginal propensity to import (MPI), among other factors.

Question 7

According to the RBA's policy guidelines, if the RBA sees rising inflation, it would then increase interest rates.

Accepted Answer

This is correct according to the RBA's policy guidelines. The RBA uses interest rates to maintain inflation within their target range, so if inflation is rising, they would increase interest rates to try to slow down spending and lower inflation.

Question 8

Keynes's theory that the interest rate adjusts to bring money supply and money demand into balance is called:

Accepted Answer

Keynes's theory that the interest rate adjusts to bring money supply and money demand into balance is called the theory of liquidity preference.

Question 9

The theory of Ricardian equivalence suggests that an increase in public saving will be balanced by an increase in private saving.

Accepted Answer

The theory of Ricardian equivalence suggests that government borrowing does not affect the overall level of savings in an economy because individuals anticipate future taxes to pay off the debt and increase their savings accordingly, not that an increase in public saving will be balanced by an increase in private saving.

Question 10

Personal income tax revenue and transfer payments act as automatic stabilisers because they fluctuate over the course of the business cycle.

Accepted Answer

Personal income tax revenue tends to decrease during economic downturns as people earn less income and therefore pay less taxes, while transfer payments such as unemployment benefits tend to increase as more people become unemployed. These changes in revenue and payments help to stabilize the economy by providing a counter-cyclical stimulus during times of recession and reducing inflationary pressures during times of expansion.

Question 11

In the liquidity preference theory, money is the most liquid asset and used as a medium of exchange.

Accepted Answer

The liquidity preference theory proposes that individuals prefer to hold their wealth in the most liquid form, which is money. Money serves as a medium of exchange, allowing individuals to easily buy goods and services.

Question 12

At a higher price level, the demand for money increases, the interest rate increases, and the demand for business and residential investment falls.Hence the aggregate-demand curve slopes downward.

Accepted Answer

As the price level increases, people need more money for transactions, which increases the demand for money. This leads to higher interest rates, making borrowing more expensive and thus reducing investment in business and residential projects. Consequently, overall demand decreases, illustrating why the aggregate-demand curve slopes downward.

Question 13

The multiplier effect suggests that the increase in aggregate demand could be smaller than the increase in government purchases, while the crowding-out effect suggests that the increase in aggregate demand could be larger than the increase in government purchases.

Accepted Answer

The multiplier effect suggests that the increase in aggregate demand will be larger than the increase in government purchases, while the crowding-out effect suggests that the increase in aggregate demand will be smaller than the increase in government purchases.

Question 14

The multipler > 1 represents a less than proportionate change on economic activity as a result of government spending.

Accepted Answer

The statement is incorrect. A multiplier greater than 1 represents a greater than proportionate change on economic activity as a result of government spending.

Question 15

Changes in government spending affect saving and growth in the long run, and aggregate demand and employment in the short run.

Accepted Answer

Changes in government spending have different effects in the short run and the long run. In the short run, an increase in government spending can boost aggregate demand, leading to higher employment and economic growth. However, in the long run, if the government spends more than it collects in revenue, it may lead to higher levels of debt and interest payments, which can reduce national saving and investment, and slow down economic growth. Therefore, changes in government spending have both short-term and long-term effects on the economy.

Question 16

Like a commodity, the money supply curve is upward sloping, reflecting the fact that the quantity of money supplied raises with the interest rate in the money market.

Accepted Answer

The money supply curve is actually vertical in the short run, meaning that the quantity of money supplied is fixed and is not affected by changes in the interest rate. In the long run, the money supply curve is upward sloping due to the ability of banks to create money through lending activities, but this is a more complex concept that is not reflected in the question.

Question 17

In the long run, the interest rate and inflation rate adjust to accommodate a fixed level of output.In the short run, the interest rate and output adjust to accommodate a predetermined level of prices.

Accepted Answer

In the long run, the economy adjusts to its natural level of output, and the interest rate and inflation rate adjust to accommodate this level of output.

Question 18

The global financial crisis has shown that the Australian government can influence the behaviour of the economy only with fiscal policy.

Accepted Answer

The global financial crisis has shown that the Australian government can also influence the behaviour of the economy with monetary policy through the actions of the Reserve Bank of Australia, such as setting interest rates and implementing quantitative easing measures.

Question 19

In order to fight recession, the RBA has to raise its inflation target in order to reduce the real interest rate needed to stimulate the aggregate demand.

Accepted Answer

Raising the inflation target can lower real interest rates, which can stimulate aggregate demand by making borrowing cheaper and encouraging spending.

Question 20

Monetary policy affects the aggregate demand via the Reserve Bank changing its inflation target.

Accepted Answer

When the Reserve Bank changes its inflation target, it can affect the interest rates, which in turn affects aggregate demand. For example, if the Reserve Bank raises its inflation target, it may need to increase interest rates to control inflation, which can decrease aggregate demand as borrowing becomes more expensive. On the other hand, if the Reserve Bank lowers its inflation target, it may decrease interest rates to stimulate the economy, which can increase aggregate demand.
