Suppose  the  United  States  economy  is  repre- sented  by  the  following  equations: Z  =  C + I + G,  C  =  500 + 0.75YD,  T  =  600,  I  =  300, YD  = Y  − T ,  G = 2000   Given the  above  variables,  calculate  the  equilibrium level  of  output. assume that   government   spending   decreases   from 2000  to  1900.   What  is  the  new  equilibrium  level  of output?  How much does income change as a result of this event?  What is the multiplier for this economy?

From the information above, calculate the level of consumption and saving that occurs at the equilibrium level of income.

The graph below shows, the aggregate demand and supply for the economy of Etrusca. a. Draw AD2 on the graph below assuming an increase of $60 in aggregate demand. Plot only the endpoints of the curve below b. What is the new level of equilibrium GDP? c. What is the new equilibrium price level? d. How much is the reduction in GDP due to the crowding out effect?

hi there is another picture as well

Use the information below for a four sector economy, answer the following questions: C 300+0.6 Yd T = 60 1 = 300 G = 650 X = 600 M 350 +0.15 Y C = Consumption function T = Tax function I = Investment function G = Government expenditures function X = Export function M=Import function Y = National Income YD = Disposable Income function Yf = Full Employment Income Ye Equilibrium income a. What is the value of autonomous expenditures? Number b. What is the slope of aggregate expenditure? Number c. What is the value of equilibrium GDP? Number d. What is the value of the autonomous tax multiplier? Number e. What is the value of Consumption (C) at equilibrium? Number f. What is the value of Savings at equilibrium? Number

could you help me, please?

8. The income-expenditure model Consider a small economy that is closed to trade, so its net exports are equal to zero. Suppose that the economy has the following consumption function, where C is consumption, Y is real GDP, I is investment, G is government purchases, and T stands for net taxes: C = 15+0.75 x (Y-T) Suppose G = $90 billion, 1 = $60 billion, and T = $20 billion. Given the consumption function and the fact that for a closed economy total expenditure can be calculated as Y=C+I+G, the equilibrium output level is equal to 5 billion. Suppose the government purchases are increased by $50 billion. The new equilibrium level of output will be equal to Based on the effect of the change in government purchases on equilibrium output, you can tell that this economy's spending multiplier is equal to

Course: Macroeconomic - IS-LM Model Prove mathematically the following: Given an increase in the proportional tax on income(t), what happens to the level of output and to the tax?" . Hint: for demostration, use the IS general function for a closed economy Y = C + I + G, where C = a + c*YD and YD = Y + TR - Y*t (where t = proportional income tax) and realize changes i.e., from "t1" to "t2"

Hi I need the second half to this problem thank you
