Answer to Problem 1QAP

True that the main determinants of investment are the level of sales and the interest rate.

Explanation of Solution

Firms with low level of sales will not required to invest further while firms with high level of sales is required to invest in order to continue the servicing of these sales. Higher the interest rate, the cost of borrowing will increase which further leads to decrease in the level of investment.

Economics Concept Introduction

Introduction: There is a direct relationship between level of sales and level of investment and inverse relationship between interest rate and level of investment.

b.

To determine

To explain: Higher level of output can be achieved only by lowering the interest rate, if all the exogenous variables in the IS relation are constant.

Answer to Problem 1QAP

True that higher level of output can be achieved only by lowering the interest rate, if all the exogenous variables in the IS relation are constant.

Explanation of Solution

The Central bank influence the borrowing and lending by lowering the interest rate which further leads to increase in the output. Assuming if all the exogenous variables in the IS relation are constant.

Economics Concept Introduction

Introduction:The IS relation shows that how the income depends on the interest rate through the relationship between demand and supply in the goods market.

c.

To determine

To explain: The IS curve is downward sloping because goods market equilibrium.

c.

Answer to Problem 1QAP

False that the IS curve is downward sloping because goods market equilibrium does notimply that an increase in taxes leads to lower level of output.

Explanation of Solution

IS curve indicates that with an increase in interest rate output decreases. Similarly with decrease in interest rate output increases which cause the downward sloping of IS curve.

Economics Concept Introduction

Introduction: The IS curve represents all the combination of income and the real interest rate such that the market for goods and services is in equilibrium.

d.

To determine

To explain: If government spending and taxes increase by the same amount, the IS curve does not shift.

Answer to Problem 1QAP

Uncertain that if government spending and taxes increase by the same amount, the IS curve does not shift.

Explanation of Solution

There might be a shift in the IS curve as a decrease in taxes that is completely offset by an increase in government spending.

Economics Concept Introduction

Introduction: The IS curve represents all the combination of income and the real interest rate such that the market for goods and services is in equilibrium.

Answer to Problem 1QAP

False that the LM curve is not horizontal at the central bank’s policy choice of the interest rate.

Explanation of Solution

Increase in income leads to increase in demand for the money which further leads increase in the interest rate. Therefore, LM curve is upward slopping.

Economics Concept Introduction

Introduction: LM curve represents the relationship the relationship between real output and interest rates.

Answer to Problem 1QAP

False that the real money supply is not constant along the LM curve.

Explanation of Solution

As output will increase, demand for real money will increase and then central bank is required to increase the supply for real money to maintain the interest rate at constant level.

Economics Concept Introduction

Introduction: LM curve represents the relationship between real output and interest rates.

Answer to Problem 1QAP

False. If the nominal money supply is $400 billion and the price level rises from an index value of 100 to an index value of 103; the real money supply would not increase

Explanation of Solution

The real money supply decreases when the nominal money supply is constant and price level increases.

Economics Concept Introduction

Introduction: LM curve represents the relationship the relationship between real output and interest rates.

Answer to Problem 1QAP

True. If the nominal money supply rises from $400 billion to $420 billion and the price level rise from an index value of 100 to 102, the real money supply rises.

Explanation of Solution

The nominal money supply rise by 10% and price level rise by 2%, which will lead to increase in real money supply.

Answer to Problem 1QAP

False. An increase in government spending does not lead to decrease in investment in IS-LM model

Explanation of Solution

An increase in government spending will increase the level of output and at the same level of interest rate; investment will increase in IS-LM model.

Economics Concept Introduction

Introduction: IS-LM model describes equilibrium in both goods and financial markets.

In the discussion of the life-cycle hypothesis, income is assumed to be constant during the period before retirement. For most people, however, income grows over their lifetimes. How does this growth in income influence the lifetime pattern of consumption and wealth accumulation shown in Figure 17-12 under the following conditions? Consumers can borrow, so their wealth can be negative. Consumers face borrowing constraints that prevent their wealth from falling below zero. Do you consider case (a) or case (b) to be more realistic? Why?
Suppose that the government creates a disincentive for private saving by increasing the tax that people pay on income from holding stocks and bonds. Construct a well-labeled diagram that depicts the effect of the policy change on the real interest rate and the equilibrium quantity of investment.
Consumption and the real interest rate: According to the life-cycle / permanent-income hypothesis, consumption depends on the present discounted value of income. An increase in the real interest rate will make future income worth less, thereby reducing the present discounted value and reducing consumption. To incorporate this channel into the model, suppose the consumption equation is given by Assume the remainder of the model is unchanged from the original setup, as in Table 11.1. (a) Derive the IS curve for this new specification. (b) How and why does it differ from the original IS curve?

  • After the global financial crisis, there has been a heated debate about whether the sluggish recovery in advanced economies reflects the secular stagnation or a slowing trend under debt overhang. Advocates of secular stagnation argue that tepid investment spending along with subdued consumption by households would result in persistent output gap and slow growth for many years to come. Also, the resulting excess of global savings over global investment in turn would put the real interest rate on a downward path. There are several explanations for this secular stagnation hypothesis. Which of the following cannot be viewed as such explanation?a. Decline in investment rates due to a dearth of profitable investment opportunitiesb. Decline in the relative price of investment goods – hence the same investment projects can be pursued by committing a smaller share of GDP, which results in a lower amount of investment in total.c. Decline in population growth rate means capital has less…
    Jack and Jill both obey the two-period Fisher model of consumption. Jack earns $200 in the first period and $200 in the second period. Jill earns nothing in the first period and $410 in the second period. Both of them can borrow or lend at the interest rate r. a. You observe both Jack and Jill consuming $200 in the first period and $200 in the second period. What is the interest rate r? b. Suppose the interest rate increases. What will happen to Jack’s consumption in the first period? Is Jack better off or worse off than before the interest rate rise? c. What will happen to Jill’s consumption in the first period when the interest rate increases? Is Jill better off or worse off than before the interest rate increase?
    What are the basic determinants of investment? Explain the relationship between the real interest rate and the level of investment. Why is investment spending unstable? How is it possible for investment spending to increase even in a period in which the real interest rate rises?
