Given the following information about each economy , either calculate the missing variable or determine that it cannot be calculated . [LO 7.2,7.3] a. If C=\$20.1 billion, I=\$3.5 billion G=\$5.2 billion, and NX=-\$1 billion, what is total income ? b. If total income is $1 trillion G=\$0.3 tr trillion , and C=\$0.5 trillion , what is I? c. If total expenditure is $675 billion, C=\$433 billion , I = $105 billion , and G=\$75 billion , what is NX ? How much are exports ? How much are imports?
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?

- For the linear IS-LM model, the goods market and the money market are in equilibrium when. Suppose that the economy is characterized by the following equations: (Y;r) = ( 1200 ; 6), Y-C-IG=0, C-Co-c(Y-T)=0,I-Io+hr=0, and kY-ur-M^s=0, which are satisfied for Co=60, lo=150, G=250, T=200, M^s=60, with the parameters c=0.8, k=0.1, h=10, and u=10.

- 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.
