3. The current account in terms of real consumption. Retrace the steps that led to eq. (27), using eq. (30) instead of eq. (24) (these last two budget constraints are equiva- lent under perfect foresight). You will obtain another version of eq. (27), 00 RC= s (1+r)B P-1 + YpY-Is-G Ps Deduce from this an alternative rendition of eq. (28) that parallels eq. (25) of Chap- ter 2: 4. 5. (1+r)B P- +--G C = 1-0 1,8 , -1) (R)- Ps Finally, compute the change in B,/P,, the stock of foreign assets measured in real consumption units. Show that this change is given by an equation exactly parallel to eq. (26) in section 2.2.2.
