%A Doh-Shin Jeon %A Domenico Menicucci %J European Journal of Law and Economics %T Data portability and competition: Can data portability increase both consumer surplus and profits? %X We study how data portability affects consumer surplus and firms’ profits in a two-period model with a switching cost where two firms compete under a non-negative pricing constraint. The firms can circumvent the constraint by tying another complementary free service (called ”freebies”) with the original service. We consider a general framework of incomplete pass-through of freebies into consumer benefit, which includes the two extreme cases of no pass-through and full pass-through as special cases. Regarding the effect on consumer surplus, data portability involves a trade-off between intensifying competition after consumer lock-in and reducing rent dissipation before consumer lock-in. We find that for an intermediate range of pass-through rates, data portability increases both consumer surplus and profits. %K Data portability %K Switching cost %K Non-negative pricing constraint %K Freebies %K Pass-through %D 2023 %C London %R 10.1007/s10657-023-09774-9 %I Kluwer %L publications48256
