I show that nearly half of these regulations entered into force before being notified. This lack of transparency has substantial consequences: advance notification more than halves the decline in export participation associated with new regulations, from 7 to 3 percentage points, by reducing temporary exits and encouraging entry, particularly among smaller firms.
Strikingly, even when notification arrives after a regulation has taken effect, export participation rebounds once information becomes available. This pattern points to regulatory uncertainty, rather than adjustment time alone, as a key mechanism, consistent with a real-options model of exporting.
The estimated tariff equivalent of timely notification ranges from 8 to 28 percentage points, highlighting the substantial trade benefits of regulatory transparency.
