Consider an economy that lasts for two periods, period 1 and period 2. Let TB1 denotes the trade bal-
ance in period t, CA the current account balance in period 1, and Bf the country's net international
investment position at the end of period 1. Let r denote the interest rate paid on assets held for one
period. Assume net international payments to employees, net unilateral transfers, and valuation changes
are always equal to zero, so that in period t = 1,2:
CA = r B_1 = TB
and
CA = B - B²_1
