We construct a partial equilibrium model of intra-industry cross-hauli
ng DFI with unionized duopoly, where wages and employment are determin
ed through Nash bargaining between firms and national labor unions. We
show that under symmetry, cross-hauling DFI is the unique Nash equili
brium, in which the negotiated wage decreases for every level of emplo
yment and each firm's profit increases. Cross-hauling DFI increases (d
ecreases) employment and national welfare if the union is wage (employ
ment) oriented.
