Résumé : The paper makes the case for a more systematic ex-ante assessment of the distribution of gains and losses from efficiency enhancing innovations that regulatory sandboxes are expected to test. It shows how a prior formal modelling of tests can inform the regulators on the possible need to control better upfront in the design of the sandbox for some otherwise underestimated but predictable distributional effects. Failing to do so is likely to lead to underestimate efficiency-equity trade-offs and other distributional issues, across stakeholders or within groups of stakeholders. Simple Industrial Organization models will often suffice to identify the potential issues at an early stage and allow better sandboxes designs and hence more reliable policy relevant results.
