The nexus of economic and political relations is a central issue in interna
tional relations, and the influence of political liberalization upon trade
ties lies at the center of much liberal theory. However, many facets of the
empirical linkage between political liberalization-including democratizati
on and the respect for human rights-and trade remain uninvestigated. Examin
ing the case of U.S.-Africa trade, this study considers two unexplored face
ts of these political determinants of trade: (1) the role of human rights c
onditions, and (2) the robustness of the relationship between democracy, hu
man rights, and trade across a subset of vertical dyads. Using a gravity mo
del to assess trade patterns, we find that neither democracy nor human righ
ts conditions has a significant impact upon U.S. trade to Africa.
