Q5. The following equation:AW₁ = TBo+r*W-1tells us that change in wealth (AW = WoW-1) equals the interest paid/earned on wealthfrom previous period and the trade balance in current period. Using the above equation andnotation from the slides, answer the following questions. Assume that unilateral transfers andcapital account equals zero.a. Write an expression for the stock of external wealth at the end of period 0 (W) as afunction of the economy's trade balance (TB), the real interest rate, and initial externalwealth (W-1).b. Write an expression for the stock of external wealth at the end of period 1 (W₁) as afunction of the economy's trade balance each period (TB), the real interest rate, andinitial external wealth (W-1). Use the given equation and your answer to part a.c. Suppose the economy faces a constraint requiring that external wealth at the end ofperiod 2 equals zero. Write down the budget constraint for the economy that the presentvalue of trade balances (in periods 0, 1, and 2) must satisfy.
