- Consider the following income/expenditure diagram in the simple Keynesian model. If taxes, T, were increased, then Group of answer choices A) The Y = C+S+T line would shift to the right, and equilibrium Y would increase. B) the C+I+G line would shift downward, and equilibrium Y would decrease. C) The Y = C+S+T line would shift to the left, and equilibrium Y would decrease. D) neither of the lines would shift, and equilibrium Y would stay the same. E) the C+I+G line would shift upward, and equilibrium Y would increase.arrow_forward7. Deriving and exploring the total expenditures curve The following graph shows total production (TP) and the level of Natural Real GDP (NRGDP) for a hypothetical economy. When Real GDP is $325 billion, consumption is $275 billion, government purchases are $50 billion, and investment is $25 billion. When Real GDP is $375 billion, consumption is $300 billion, government purchases are $50 billion, and investment is $25 billion. Use the blue line (circle symbol) to plot the economy's total expenditure function within a simplified Keynesian framework. 450 425 X 400 375 TOTAL EXPENDITURE (Billions of dollars) 500 475 350 325 300 300 TP NRGDP 325 350 375 400 425 REAL GDP (Billions of dollars) 450 475 500 TE ?arrow_forwardAccording to Keynes’ Law... A) The total demand for products determine the level of gross domestic product and may not equal the supply capacity of the economy in the short run. B) The total demand always equals the total supply capacity in the short run. C) The total demand tends to rise above the total supply capacity in the short run which leads to recessions D) The total supply of products determines the level of gross domestic product and the level of demand in the economy in the long run.arrow_forward
- Assuming that there is no government spending or trade, an economy’s GDP is the sum of domestic consumption C and investment I, i.e. Y = C+ I Assume that I is unaffected by GDP Assume the consumption function is C = c0 + c1Y In any equilibrium aggregate demand, AD must be equal to Y, GDP. Given this model, which FIVE of the following statements are correct? Select one or more: A. If the economy above is a demand-driven economy, then the equilibrium solution for Y is given by Y = m(c0 + I), where m = 1/(1 - c1) is the multiplier. B. if c1 = 0.8 the multiplier is equal to 1/0.8= 1.25 C. if c1 = 0.75 the multiplier is equal to 4 D. assume c0 =100, I=50, c1=0.6. The equilibrium value of Y in a demand-driven economy is 300. E. Assume that Y is initially 400, I is initially 100, and the multiplier is 2.5. I increases by 10%. The multiplier implies that in equilibrium Y will increase by 25%. F. The higher is c1 the larger is the multiplier G. If consumers…arrow_forwardIf the price level increases, what happens to the consumption function? Why?arrow_forwardLRAS, LRAS₂2 A. B. C. D. E.
