In Keynesian economics, the multiplier effect refers to the process by which an initial change in government spending leads to a larger change in equilibrium income. When the government increases its spending, it increases demand for goods and services, which leads to an increase in income and output. However, financing the spending with a tax increase reduces disposable income and thus reduces consumption, leading to a smaller increase in equilibrium income. The change in equilibrium income depends on the marginal propensity to consume (MPC). The MPC is the fraction of additional income that is spent on consumption. If the MPC is high, the multiplier effect is stronger, leading to a larger increase in equilibrium income.
- (A) Unchanged: This is incorrect. The equilibrium income will change because the increase in taxes will reduce consumption, which affects the overall equilibrium income.
- (B) Increased by 1: This is incorrect. The increase in government spending will be offset by the decrease in consumption due to higher taxes, so the increase in equilibrium income is less than 1.
- (C) To change depending on the value of the marginal propensity to consume: This is correct. The effect on equilibrium income depends on the MPC. A higher MPC leads to a larger increase in equilibrium income.
- (D) Decrease by 1: This is incorrect. The decrease in income is not necessarily 1; it depends on the value of the MPC and the multiplier effect. The correct answer is (C), as the effect on equilibrium income depends on the value of the marginal propensity to consume.
Final Answer: (C) To change depending on the value of the marginal propensity to consume.
In the context of the Keynesian concept of a multiplier, a \(\$\)1 increase in government spending financed by a \(\$\)1 increase in taxes will cause equilibrium income to:
Which of the following statements are correct about the IS curve?
(A) It shows the combination of the interest rate and the level of income such that the money market is in equilibrium.
(B) It is negatively sloped.
(C) The smaller the multiplier and the more sensitive investment spending is to changes in the interest rate, the steeper the IS curve.
(D) An increase in government purchases shifts the IS curve to the right.
