Chapter 12: Q. b-For Critical Thinking (page 264)

In principle, what might be possible causes of the observed diminishment of the rightward shifts of Germany's investment function over time? (Hint: Recall that changes in productive technology or business tares affect levels of planned investment spending.)

Short Answer

Expert verified

Executives repeatedly emphasized Germany's existing competitive advantage in terms of the country's well-established technical networks, which enable efficient information and experience sharing.

Step by step solution

01

Introduction.

Purchases of machinery, land, factors of production, or infrastructure are examples of investment spending.

Investing expenditure differs from investment, which is the acquisition of assets such as stocks, securities, and futures. Another name for it is capital formation.

02

Germany's investment function.

The repercussions of the global economic crisis in Germany were as follows: industrial production in Germany fell by 40%during this period. Inflation was strong, and the currency had depreciated as a result. There was a lot of unemployment, so people stood on the side of the road announcing that they would do any job.

In light of the above discussion, how is a greater degree of habit persistence in consumption likely to affect the marginal propensity to save? Explain your reasoning.

Consider the table below when answering the following questions. For this economy, the marginal propensity to consume is constant at all levels of real GDP, and investment spending is autonomous. Equilibrium real GDPis equal to \(8,000. There is no government.


a. Complete the table. What is the marginal propensity to consume? What is the marginal propensity to save?

b. Draw a graph of the consumption function. Then add the investment function to obtain C+I.

c. Under the graph of C+I, draw another graph showing the saving and investment curves. Does theC+Icurve cross the45-degree reference line in the upper graph at the same level of real GDPwhere the saving and investment curves cross in the lower graph, at the equilibrium real GDPof \)8,000? (If not, redraw your graphs.)

d. What is the average propensity to save at equilibrium real GDP?

e. If autonomous consumption were to rise by $100, what would happen to equilibrium realGDP?

Take a look at Table 12-2 and consider the changes in planned real consumption and saving associated with an increase in real GDP from \(14.0 trillion to \)15.0 trillion to calculate the marginal propensity to consume.

The multiplier in a country is equal to5, and households pay no taxes. At the current equilibrium real GDP of \(14trillion, total real consumption spending by households is \)12trillion. What is real autonomous consumption in this country?

Consider the table below when answering the following questions. For this hypothetical economy, the marginal propensity to save is constant at all levels of real GDP, and investment spending is autonomous. There is no government.

a. Complete the table. What is the marginal propensity to save? What is the marginal propensity to consume?

b. Draw a graph of the consumption function. Then add the investment function to obtain C+I.

c. Under the graph of C+I, draw another graph showing the saving and investment curves. Note that the C+Icurve crosses the 45-degree reference line in the upper graph at the same level of realGDPwhere the saving and investment curves cross in the lower graph. (If not, redraw your graphs.) What is this level of real GDP?

d. What is the numerical value of the multiplier?

e. What is equilibrium real GDPwithout investment? What is the multiplier effect from the inclusion of investment?

f. What is the average propensity to consume at equilibrium real GDP?

g. If autonomous investment declines from \(400to \)200, what happens to equilibrium real GDP?
