In this paper, we use a linked employer-employee database from Brazil to examine the impact of trade reform on the wages of workers employed at heterogeneous firms. Our analysis of data at the firm level confirms earlier findings of a differential positive effect of trade liberalization on average wages at exporting firms relative to non-exporting firms. However, the analysis of average firm-level wages is incomplete along several dimensions. First, it cannot fully account for the impact of a change in trade barriers on workforce composition, especially in terms of unobservable (time-invariant) worker characteristics (innate ability) and any additional productivity that results from employment in a specific firm (match-specific ability). Furthermore, the firm-level analysis is undertaken u...

This paper studies empirically the links between international trade and labor income risk faced by workers in the United States. We use longitudinal data on workers to estimate time-varying individual income risk at the industry level. We then combine our estimates of persistent labor income risk with measures of exposure to international trade to analyze the relationship between trade and labor income risk. Importantly, by contrasting estimates from various sub-samples of workers, such as those who switched to a different industry (or sector) with those who remained in the same industry throughout the sample, we study the relative importance of the different channels through which international trade affects individual income risk. Finally, we use these estimates to conduct a welfare ana...
