3. Suppose that you are interested in answering the question of how consumption reacts to tax increases. In recent years, government has imposed tax increases to fund increased infrastructure spending. If you could design an ideal experiment to answer this question, how would you do so? Do you think it would be practical to use this experiment on a large scale?
Suppose that the least amount of goods and services that Roberto will consume in a year is $40,000.Roberto tends to save $0.30 of every dollar of disposable income that he makes. Use the given line to graph Roberto's consumption function for disposable income levels between $0 and $200,000. Move each endpoint to the appropriate spot on the graph.
U = c¹/² + Bc¹²/2 tt+1 A) Suppose that the household faces two within period budget constraints of the form: C++ 1 = Y++1 + (1+r)s Combine the two period budget constraints into one intertemporal budget constraint. B) Use the intertemporal budget constraint and this utility function to derive the Euler equation characterizing an optimal consumption plan. C) Use this Euler equation and the intertemporal budget constraint to derive a consumption function expressing cas a function of Y, Y₁+1, and rt.
6) Suppose the economy is closed and is characterized by the following behavioral equations: C=C₁+C₁YD Y₁ = Y-T I=b₁ + b₂Y a. Government spending and taxes are constant. Solve for the equilibrium output. What is the value of the multiplier? How does the relationship between investment and output affect the value of the multiplier as compared to the case when investment was exogenous? For the multiplier to be positive what condition must (c₁ +b₁ ) satisfy? Explain your answers? b. Suppose that the parameter bo, sometimes called business confidence, increases. How will the equilibrium output be affected? Will investment change by more or less than the change in bo? Why? What will happen to national saving?

1) In the IS equation why wasnt G in the calculations. 2)Suppose that with all exogenous variables, including T and M at their original values, households become less confident about the future and reduce their autonomous level of consumption from 200 to 150. Solve for the new values of e, Y and NX. With the help of graphs, explain very carefully the mechanisms by which a new equilibrium is reached. 3)Suppose that with all exogenous variables at their original values, the autonomous part of money demand increases to 70. Solve for the new values of e, Y and NX. With the help of graphs, explain very carefully the mechanisms by which a new equilibrium is reached.
Suppose that the least amount of goods and services that Jim will consume in a year is $40,000. Jim tends to save $0.30 of every dollar of disposable income that he makes. Use the given line to graph Jim's consumption function for disposable income levels between $0 and $200,000. Move each endpoint to the appropriate spot on the graph.

Consider an economy where individuals live for two periods only. Their utility function over consumption in periods 1 and 2 is given by U = 2 log(C1) + 2 log(C2), where C1 and C2 are period 1 and period 2 consumption levels respectively. They have labor income of $100 in period 1 and labor income of $50 in period 2. They can save as much of their income in period 1 as they like in bank accounts, earning interest rate of 5 percent per period. They have no bequest motive, so they spend all their income before the end of period 2. a. What is each individual’s lifetime budget constraint? If they choose consumption in each period so as to maximize their lifetime utility subject to their lifetime budget constraint, what is the optimal consumption in each period? How much do the consumers save in the first period? b. Suppose that the government introduces a social security system that will take $10 from each individual in period 1, put it in a bank account, and transfer it back to…
