Explanation of Solution
The slope of the linear equation is the MPC; here, it is equal to 0.8. Thus, MPC is 0.8.

- Crusoe will live this period and the next period as the lone inhabitant of his island. His only income is a crop of 100 coconuts that he harvests at the begin- ning of each period. Coconuts not consumed in the current period spoil at the rate of 10 percent per period. (LO5) a. Draw Crusoe’s intertemporal budget constraint. What will be his consump- tion in each period if he regards future consumption as a perfect, one-for- one substitute for current consumption? b. What will he consume each period if he regards 0.8 unit of future consump- tion as being worth 1 unit of current consumption?arrow_forward12. Given this diagram of Consumption and Savings functions, What will be the level of savings at an income level of 60? 6. Given this diagram of Consumption and Savings functions, What will be the level of savings at an income level of 20? 07. Given this diagram of Consumption and Savings functions, What is the level of total desired consumption at income level of 80? 8. Given this diagram of Consumption and Savings functions, What is the level of "induced consumption" at income level of 40arrow_forward1. According to the Bureau of Economic Analysis, during therecession of 2007–2009, household saving as a fraction of dis-posable personal income increased from a low of just over1 percent in the first quarter of 2008 to 5 percent in the secondquarter of 2009. All else equal, what impact would this changein saving have on the MPC, MPS, and multiplier? How wouldthis change affect equilibrium output when planned invest-ment changes? 2. Assume in a simple economy that the level of saving is –500 whenaggregate output equals zero and that the marginal propensity tosave is 0.2. Derive the saving function and the consumption func-tion, and draw a graph showing these functions. At what level ofaggregate output does the consumption curve cross the 45° line?Explain your answer and show this on the graph.arrow_forward
- 7 Consider a model in which an individual lives only two periods. This person has diminishing marginal utility of consumption and receives an income of $20,000 in period 1 and an income of $5,000 in period 2. The private interest rate is 10 percent per period, and this person can borrow or lend money at this rate. Also assume that this person intends to consume all of his income over his lifetime. a. Give a hypothetical numerical example of what a person’s optimal consumption would be over these two periods. In answering this question, what assumptions did you make?arrow_forwardSuppose that consumer spending initially rises by $5 billion for every 1 percent rise in household wealth and that investment spending initially rises by $20 billion for every 1 percentage point fall in the real interest rate. Also assume that the economy�s multiplier is 3. If household wealth falls by 6 percent because of declining house values, and the real interest rate falls by 2 percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level? The aggregate demand curve will shift_____ by $____ billion. In what direction and by how much will it eventually shift? The aggregate demand curve will shift_____ by $____ billion..arrow_forward6 Suppose a closed economy with no government spending or taxing initially. Suppose also that intended investment is equal to 100 and the aggregate consumption function is given by C = 250 + 0.75Y.

Consumption, as you would expect, does depend on income via the consumption function C = 2 + 0.75Y – 0.75T. Net taxes are T = 12. Your friend thinks that the equilibrium will be where Y = 150 but he is wrong.
