Product Market Integration and Wages in Unionized Countries

This paper addresses the effects of product market integration on wages. We develop a two–country general equilibrium model of international trade with imperfectly competitive product markets and unionized labor markets. Integration is modelled as either a fall in fixed or variable trade costs. A reduction in fixed trade costs leads to an unambiguous decrease in wages, whereas a reduction in variable trade costs has an ambiguous effect on wages.
