Global trade and economics

International trade shapes how firms grow, innovate, and compete by exposing them to larger markets, foreign technologies, and new competitive pressures. Economists study these dynamics using detailed firm-level data to understand why some businesses thrive when borders open while others contract, and how aggregate productivity and welfare shift as a result of liberalization. Central open questions include how the gains from trade are distributed across workers and regions, whether exporting itself drives productivity improvements or merely selects the firms that were already more capable, and how trade policy interacts with technological change to determine long-run growth trajectories.
