摘要:

This paper analyzes the long-run effects and short-run effects of foreign aid
on the domestic economy by using the Hamilton system and Laplace transform. It is
found that an increase in the foreign aid has no long-run effect on the foreign borrowing,
domestic capital accumulation and the foreign direct investment in the home country, but
increases the steady-state consumption level the same amount. However, the short-run
analysis presents that increasing foreign aid does not affect the initial consumption level
and the initial consumption increase rate; but it affects the initial savings positively.
