Labor Market Power and the Pro-competitive Gains from Trade
Abstract
We build into a model of trade with market power in product markets and strategic complementarities in price-setting labor market power, strategic complementarities in wage-setting, and a rich structure of product and labor markets to study the pro-competitive gains from trade. We combine our model with confidential firm-level data from Australia to quantify the welfare and efficiency gains of higher exposure to international trade. We find that closing the economy to trade has significant and negative effects on welfare and aggregate labor productivity. In a perfectly competitive economy, where there is no firm market power, welfare losses are only 40% of the total effect which indicates that imperfect competition is the main driver behind these losses. Contrary to common belief, these losses are amplified by the presence of labor market power, which accounts for almost half of the total effect. We find that, at the aggregate level, the pro-competitive effect is well approximated by models of firm market power that leave aside strategic complementarities both in price- and wage-setting. However, these models hide how the losses materialize. Our results highlight the importance of market structure, firm competition, and strategic complementarities for the quantification of the gains from trade liberalizations.
