Unless free international lending/borrowing is allowed, domestic saving equals domestic investment and hence saving and investment taxes have the identical effect, as is the case in a closed-economy context. However, if it is allowed, households can accumulate foreign assets besides domestic capital and hence saving and investment are separated, causing the two taxes to have different effects. Using a two-sector growth model, we show that the two taxes generate completely different effects on industrial structure. The investment tax always shrinks the capital-intensive sector whereas the saving tax may well expand it.
