Robot adoption and export performance: Firm-level evidence from Spain

Export activities are crucial for firm performance. Existing evidence shows that technology adoption is an essential determinant of firm competitiveness. Nevertheless, scarce attention has been devoted to robotisation, a new technology that firms increasingly adopt. We investigate the effect of robot adoption on the intensive and extensive margins of exports of Spanish manufacturing firms over the period 1990-2014. We combine the pro-pensity score matching (PSM) and difference in differences (DID) techniques and find that firms adopting robots experience a sharp increase in their export probability, export sales and share of exports in total output. This result persists after a wide array of robustness checks, including the use of instrumental variables. Robot adoption fa-vours export entry and survival and fosters the export activity of intermediate goods' producers. The positive impact of robot adoption on exports is driven by its positive effect on firm total factor productivity, product innovation and importing.
