A new foreign aid initiative called Aid for Trade is intended to improve a recipient's trade-related infrastructure which lowers its trade costs. We formulate a two-country, continuum-good Ricardian model, where each country's transport cost is inversely related to its effective public services which are subject to congestion. Our numerical experiments show that an increase in the donor's aid/GDP ratio within a certain range raises welfare in both countries if the recipient's relative income tax rate is sufficiently small.
