Trade liberalization and its fiscal implications in a north-south trade model

We study the fiscal implications of trade liberalization in a North-South trade model with nonhomothetic preferences. Combining a Ricardian trade model with a continuum of competitive goods and a public good, nonhomothetic preferences imply that both the global income distribution and the local income distribution matter for gauging the effects of different trade liberalization regimes on income taxes and public good provision. The fiscal implications of tariff reductions are typically more adverse for poorer countries than for richer countries. We also find that unilateral trade liberalization by richer countries is a more viable policy option to pursue than multilaterally reducing tariffs.
