Explain the short-run and long-run effects of an exogenous decrease in investment by explanation and using graphical analysis.

Consider the household model that you have seen in class but now assume that the goal of the household is to consume twice as much in period 2 as in period 1. She earns $100 in the first period and $150 in the second period. The interest rate is 5%. What is her optimal saving in the first period? Note: Type in your answer approximated to two decimal points, i.e., your answer must be of the form "999.99". I will not be able to fix correct answers that were entered incorrectly, such as "999.999" or "999,99" or "999". In case the last digit in the correct answer is zero, e.g., "999.90" or "999.00", Blackboard will automatically delete it and you should not do anything about it.

Use the two-period model from the Appendix to answer this question.Your current income is 40,000. Your next period (future) income is known to be 40,000.If your current consumption expenditure is 32,000, your (current) level of savings S=____(Enter your answer as a whole number.)

Question: Suppose that the marginal cost of extracting a non-renewable natural resource is MXC(Q) = 10 and the marginal beneÖt of using the resource are MB(Q) = 90Q. In the context of a static model, address the following question: Calculate the efficient value of Q if the total stock of the natural resource is Q = 50: Provide a graphical representation of the solution.   My Note: This is my first time resubmitting, I was told to confirm that MXC(Q) =10 is the correct form of the Marginal cost of extraction to answer this question correctly. I'm not sure but this is the way my professor asked his question.

The algebraic form of the consumption function is: Disposable Income YD-Y-T $0 Consumption Spending C = C₁ + MPC(YD) Investment Spending | $1,000 $250 $1,000 $1,750 $250 $2,000 $2,500 $250 $3,000 $3,250 $250 $4,000 $4,000 $250 $5,000 $4,750 $250 $6,000 $5,500 $250 Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. C=$1,000+ 0.25(Y-T) = $1,000+ 0.25(YD). b C = $250 +0.75(YT) = $250 +0.75(YD). с C = $1,000+ 0.75(Y-T) = $1,000+ 0.75(YD). d C=$750 +0.75(Y-T) = $750 +0.75 (YD). Your answer

Economics Help: Please see attached. Screenshot 1 is the context and screenshot 2 is the drop downs. I just need the answer to the drop downs please

Sub : EconomicsPls answer very fast.I ll upvote correct answer. Thank You

Saving in the economy Multiple Choice Occurs when current spending is less than current incomes. and investment are essentially the same concept. Occurs when current consumption is more than current output. is generally not a determinant of future output.

Consumption-savings decisions involve intertemporal choice as this is a decision involving a tradeoff between current and future investment. consumption and investment. current and future consumption. consumption and saving. consumption per worker and income per worker. OO

3. Analytic Question on Durable Consumption It is known that durable consumption is more sensitive to interest rates and expected income. In this question, we investigate if this is the case in the context of the model we have been studying. We investigate the following decision: U (c1, c2) 1 max {c1,c2} 2 VCi + xo + subject to the following budget constraints: The time 1 budget constraint: a = Y1 - Ci and the time 2 budget constraint: C2 = Y2 + (1 +r) a. The novelty is that ro is now a variable to represents past purchases of goods 1. You can think of this as a car. In turn, we have that x1 = c1 so a1 is consumption derived utility in period 2 derived from past purchases. For this question assume that B (1+ r) = 1. Answer the following questions. а. Substitute out a from both budget constraints, the one at time 1 and time 2, to write a single intertemporal budget constraint. b. Show that the Euler equation (the equation that relates the marginal utility of consumption to the interest…
