The intergenerational welfare effects of government deficits are exami
ned in a simple life-cycle economy which can borrow at given interest
rates and import at given prices but has unexploited market power in e
xports. Despite perfect capital market integration, a deficit-financed
tax cut to the current young causes an immediate real exchange rate a
ppreciation, raising the after-tax wage by more than the tax cut and l
owering the rate of return on domestic assets. Subsequently, the real
exchange rate depreciates to a lower steady-state value, and the after
-tax wage decreases by more than the tax increase needed to service th
e larger deficit.
