The U-Shaped Productivity Dynamics of French Exporters
Abstract
We use data on French manufacturing firms to reveal that the productivity dynamics of new exporters is typically U-shaped. Prior to entry, firm productivity temporarily decreases, then recovers contemporaneously with entry, as the benefits from sales to foreign markets accrue. We show that the U-shaped pattern is more pronounced for intensively exporting firms and for firms operating in capital-intensive or high-technology sectors. This finding suggests that firms prepare to become exporters through prior specific investments and learning-to-export mechanisms. We then point to the limitations of studies that focus only on date of entry to exporting to discriminate between self-selection versus learning mechanisms.
