D.1. Introducing the data localisation shocks one by one

Figure A D.1 displays the projected change in real exports and real GDP for the four scenarios with the three types of costs (trade costs, WTP, and data management costs) entered one at a time. In Scenario A No data localisation, there is a small contribution of trade cost reductions, because the interaction of data flow and data localisation policies on trade costs is considered. Lifting data localisation policies would for some regions with less restrictive data flow policies imply a reduction in the costs of transferring data and thus an expansion of trade. At the global level the impact is marginal, because this only happens in isolated cases. The contribution of WTP/trust is larger to the expansion of real GDP and real exports, since the isolated regions would move to a safeguards regime with higher levels of trust when restrictive data localisation policies are lifted.
