Labor market distortions provide a second-best case for protection. Ho
wever, the implications are less obvious when the product market is im
perfectly competitive too, as suggested by several partial equilibrium
studies. This paper adopts a general equilibrium approach, combining
unionization in labor markets with monopolistic competition in product
markets. Two labor market settings are considered: fully centralized
wage bargaining (''Scandinavia'', for short) and negotiation at the fi
rm level (''Latin America'). The competitive labor market case is used
as a benchmark. It is shown that in Latin America the second-best tar
iff is higher, and the welfare level lower, than in the benchmark case
. Scandinavia reaches the first best under free trade.
