All flashcards
Flashcard 1: State the formula for the tax multiplier.
Answer: 1−MPC−MPC. Negative because tax increases reduce disposable income.
Flashcard 2: What is the relationship between MPS and MPC?
Answer: MPS = 1 - MPC. Income must be either consumed or saved, so they sum to 1.
Flashcard 3: What is the impact of fiscal policy on multipliers?
Answer: Influences GDP through spending and taxation. Government uses multipliers to predict policy effectiveness.
Flashcard 4: What is the implication of a high tax rate on disposable income?
Answer: Reduces disposable income. Higher taxes leave consumers with less money to spend.
Flashcard 5: Identify the impact on GDP of an increase in foreign demand.
Answer: GDP increases. Higher foreign demand increases exports and domestic GDP.
Flashcard 6: What does a tax cut signify in terms of economic stimulation?
Answer: Increases economic activity. Tax cuts boost disposable income and consumer spending.
Flashcard 7: What is the relationship between the tax multiplier and MPC?
Answer: Directly proportional. Higher MPC makes the tax multiplier more negative (larger magnitude).
Flashcard 8: What does a tax cut signify in terms of economic stimulation?
Answer: Increases economic activity. Tax cuts boost disposable income and consumer spending.
Flashcard 9: Express the change in GDP with a $200 increase in exports, MPC = 0.9.
Answer: GDP increases by $2000. Using export multiplier: $200 × 10 = $2000.
Flashcard 10: How does a decrease in government spending affect GDP?
Answer: GDP decreases. Government spending directly adds to aggregate demand.
Flashcard 11: Identify the result of a $100 increase in government spending, MPC = 0.75.
Answer: GDP increases by $400. Using spending multiplier: $100 × 4 = $400.
Flashcard 12: What is the effect of a decrease in exports on GDP?
Answer: GDP decreases. Exports are a component of aggregate demand.
Flashcard 13: State the effect of a high savings rate on multipliers.
Answer: Weakened multipliers. High savings reduces MPC, weakening all multiplier effects.
Flashcard 14: State the effect of a high savings rate on multipliers.
Answer: Weakened multipliers. High savings reduces MPC, weakening all multiplier effects.
Flashcard 15: What is the direct effect of an increased investment on GDP?
Answer: Increases GDP. Investment is a component of aggregate demand.
Flashcard 16: How does a decrease in government spending affect GDP?
Answer: GDP decreases. Government spending directly adds to aggregate demand.
Flashcard 17: What does MPS stand for in economics?
Answer: Marginal Propensity to Save. The fraction of additional income that consumers save.
Flashcard 18: What is the impact of fiscal policy on multipliers?
Answer: Influences GDP through spending and taxation. Government uses multipliers to predict policy effectiveness.
Flashcard 19: What does MPS stand for in economics?
Answer: Marginal Propensity to Save. The fraction of additional income that consumers save.
Flashcard 20: What does a multiplier greater than 1 indicate?
Answer: Amplified effect on GDP. Each dollar of spending creates more than one dollar of GDP.
Flashcard 21: What is the impact of a balanced budget multiplier?
Answer: Equal change in GDP. Equal increases in spending and taxes have a net multiplier of 1.
Flashcard 22: What is the formula for the change in GDP from a tax cut?
Answer: Tax cut × Tax multiplier. Tax cuts stimulate GDP through the negative tax multiplier.
Flashcard 23: What does a negative tax multiplier signify?
Answer: Inverse relationship with GDP. Tax increases reduce GDP, hence the negative multiplier.
Flashcard 24: What is the formula for the change in GDP from a tax cut?
Answer: Tax cut × Tax multiplier. Tax cuts stimulate GDP through the negative tax multiplier.
Flashcard 25: What is the effect of a higher MPC on consumption?
Answer: Increases consumption. Higher MPC means people consume more of each dollar earned.
Flashcard 26: What is the formula for the net export multiplier?
Answer: 1−MPC1. Net exports work the same way as other spending injections.
Flashcard 27: State the effect of an increase in savings on economic activity.
Answer: Reduces economic activity. More savings means less consumption and spending.
Flashcard 28: What is the implication of a high tax rate on disposable income?
Answer: Reduces disposable income. Higher taxes leave consumers with less money to spend.
Flashcard 29: State the effect of a decrease in taxes on GDP.
Answer: GDP increases. Tax cuts increase disposable income and consumption.
Flashcard 30: What is the direct effect of an increased investment on GDP?
Answer: Increases GDP. Investment is a component of aggregate demand.
Flashcard 31: What determines the strength of a multiplier effect?
Answer: Value of MPC. Higher MPC creates larger multipliers for all types.
Flashcard 32: What is the formula for the spending multiplier?
Answer: 1−MPC1. Based on how much of each dollar is spent vs. saved.
Flashcard 33: Express the spending multiplier in terms of MPS.
Answer: MPS1. Since MPS=1−MPC, this is equivalent to the standard formula.
Flashcard 34: Identify the effect of a high MPC on the tax multiplier.
Answer: Larger absolute value of tax multiplier. Higher MPC makes the tax multiplier more negative.
Flashcard 35: Identify the result of a $100 increase in government spending, MPC = 0.75.
Answer: GDP increases by $400. Using spending multiplier: $100 × 4 = $400.
Flashcard 36: What is the effect on GDP of a simultaneous increase in taxes and spending?
Answer: GDP increases by the amount of spending increase. The balanced budget multiplier always equals 1.
Flashcard 37: State the formula for the balanced budget multiplier.
Answer: Always equal to 1. Spending and tax effects exactly offset when changed equally.
Flashcard 38: What does a multiplier greater than 1 indicate?
Answer: Amplified effect on GDP. Each dollar of spending creates more than one dollar of GDP.
Flashcard 39: What is the effect of a decrease in exports on GDP?
Answer: GDP decreases. Exports are a component of aggregate demand.
Flashcard 40: Identify the impact on GDP of an increase in foreign demand.
Answer: GDP increases. Higher foreign demand increases exports and domestic GDP.
Flashcard 41: What determines the strength of a multiplier effect?
Answer: Value of MPC. Higher MPC creates larger multipliers for all types.
Flashcard 42: What is the formula for the net export multiplier?
Answer: 1−MPC1. Net exports work the same way as other spending injections.
Flashcard 43: What does a negative tax multiplier signify?
Answer: Inverse relationship with GDP. Tax increases reduce GDP, hence the negative multiplier.
Flashcard 44: What is the relationship between the tax multiplier and MPC?
Answer: Directly proportional. Higher MPC makes the tax multiplier more negative (larger magnitude).
Flashcard 45: Which multiplier is generally larger, spending or tax?
Answer: Spending multiplier. Spending has no negative sign, making it larger in absolute value.
Flashcard 46: What is the significance of a multiplier in economic analysis?
Answer: Assess impact of fiscal changes. Multipliers help predict how policy changes affect GDP.
Flashcard 47: How does consumer confidence affect the multiplier?
Answer: Higher confidence strengthens multiplier. Confidence affects how much people spend from additional income.
Flashcard 48: State the formula for the tax multiplier.
Answer: 1−MPC−MPC. Negative because tax increases reduce disposable income.
Flashcard 49: What is the impact of a balanced budget multiplier?
Answer: Equal change in GDP. Equal increases in spending and taxes have a net multiplier of 1.
Flashcard 50: What happens to the multiplier if MPC increases?
Answer: Multiplier increases. Higher MPC means more spending per dollar, amplifying effects.

Answer: GDP increases by $2500. Using spending multiplier: $500 × 5 = $2500.
Flashcard 57: Which factor does not affect the spending multiplier?
Answer: Tax rate. Spending multiplier depends only on MPC, not tax rates.
Flashcard 58: How does an increase in MPS affect the spending multiplier?
Answer: Multiplier decreases. Higher saving means less spending, reducing the multiplier.
Flashcard 59: What is the significance of a multiplier in economic analysis?
