In particular, we take advantage of Costa Rica's gradual policy driven change from a paper-based to an electronic trade single window that allows for streamlined administrative procedures to obtain product-specific authorizations required to export to identify the impact of information technologies on firms' exports. 1We carry out difference-in-differences estimations on highly disaggregated firm-level export data from Costa Rica over the period 2007-2013 that distinguish whether shipments' required documentation was processed manually and separately with each intervening agency -even when potentially presented at a single physical entry point-or electronically in a simultaneous manner for all relevant agencies.

This effect has been stronger for firms that have to interact with several public 1 More specifically, Costa Rica imple...
