After a repeal of North Dakota's Sunday morning retail ban, morning visits to Walmart stores rose sharply, reducing cross-border travel & shifting shopping to preferred times and stores.

Sunday morning store closures impose significant costs on consumers, but supporters of such ‘blue laws’ argue these rules protect workers, family life, and small retailers. This column uses GPS data to study the effects of lifting North Dakota’s strict Sunday morning retail ban in 2019. After the repeal, Sunday morning visits to Walmart stores rose sharply, reducing cross-border travel and shifting shopping to preferred times and stores. The consumer welfare loss from the ban was equivalent to an extra 1.4 miles (2.25 km) per shopping trip, highlighting a trade-off between a day of shared rest and consumer flexibility.
