Suppose the government of Lilliput, a closed economy, increases its spending while investment demand rises simultaneously. Briefly discuss the long-run impact on private saving, public saving, national saving, the domestic real interest rate, and investment according to the classical model of a closed economy (5 marks).Note: Explain your answers for national saving, the domestic real interest rate and investment by mentioning the impacted curve(s) and direction of curve shifts in the market for loanable funds.

In the classical model of a closed economy, which of the following best describes the effect of an increase in the real interest rate on national savings and investment, assuming the economy is initially in equilibrium?

In the classical model of a closed economy, assume that the government decides to increase its spending (G) without increasing taxes. What is the most likely impact on the equilibrium real interest rate and investment, assuming that the total production of goods and services in the economy (national output) remains unchanged? 3. Add options A. The real interest rate will decrease, and investment will increase. This option is incorrect because it misinterprets the effects of increased government spending. An increase in government spending without a corresponding increase in taxes typically reduces national savings. This reduction in savings decreases the supply of loanable funds, leading to an increase in the real interest rate, not a decrease. Higher interest rates make borrowing more expensive, reducing investment rather than increasing it. B. The real interest rate will decrease, and investment will decrease. This option is incorrect because it incorrectly suggests that an increase in government spending would lead to a decrease in the real interest rate. According to the classical model, an increase in government spending reduces the supply of loanable funds, which raises the real interest rate, not lowers it. The idea that investment would decrease in this scenario is correct, but it’s not due to a lower interest rate—it’s due to a higher one. C. The real interest rate will remain unchanged, and investment will increase. This option is incorrect because it suggests that the real interest rate is unaffected by changes in government spending. In reality, in the classical model, a reduction in national savings (due to increased government spending) leads to a higher real interest rate. The suggestion that investment would increase under these conditions is also flawed, as higher borrowing costs typically reduce investment. D. The real interest rate will increase, and investment will decrease. This is the correct answer. When the government increases spending without raising taxes, national savings decrease because the government is using funds that could otherwise be saved. This reduction in savings shifts the supply of loanable funds to the left, causing the real interest rate to rise. As borrowing becomes more costly due to higher interest rates, investment tends to decrease. 请帮我检查一下我创建的问题以及解释答案是否正确

Consider the closed economy of the country of Examnia from the perspective of the classical model. Suppose the government of Examnia engages in expansionary fiscal policy by increasing government expenditure. Briefly discuss the impact on private saving, public saving, national saving, investment, and the domestic real interest rate.

QUESTION 2Assume the graph below indicates the long-run impact on the loanable funds market of a closed economy. Select all scenarios for which the above graph correctly illustrates the long-run effect according to the classical model.Note: This is a multiple-answer question; thus, more than one option may be correct.a.An increase in government expenditure.b.A decrease in transfer payments.c.A decrease in taxes.d.A decrease in government expenditure.
