In this paper, I examine the effect of trade reform on regional employ
ment in Mexico. Three factors condition regional labor demand. (1) tra
nsport costs, which encourage firms to locate in regions with good acc
ess to foreign markets; (2) backward-forward linkages, which encourage
firms to locate near buyers and suppliers, and (3) agglomeration econ
omies, which reinforce the pre-trade pattern of industry location. The
results suggest transport costs and backward-forward linkages influen
ce regional employment. Post-trade employment growth is relatively hig
h in regional industries that are close to the United States and near
upstream and downstream industries. Trade reform appears to have contr
ibuted to the breakup of the Mexico City manufacturing belt and the fo
rmation of new industry centers in northern Mexico. (C) 1998 Elsevier
