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.

Map of Walmart Supercenter locations in North Dakota and neighbouring states.

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.

This paper examines the effects of deregulating store opening hours, specifically focusing on North Dakota's repeal of its Sunday closing law in 2019.

Summer 2025 reality check for those who rely on LLMs for help with math and logic: chatgpt.com/s/t_6880b52a...
I tested four models, all gave wrong answers (ChatGPT (4o), Gemini (2.5flash), Perplexity, DeepSeek). For some other numbers, the answers were correct.

I think people don’t yet realize that the new Pope might prefer Chicago-style pizza over Italian pizza.

A deep joke by DeepSeek?

The result? All three could solve Gemini’s and DeepSeek’s problems, but only DeepSeek solved ChatGPT’s! Impressive.
toomas.hinnosaar.net
I did a simple test to check the math capabilities of three AI models: ChatGPT (model o1), Gemini (2.0 experimental), and DeepSeek (DeepThink R1). I asked each to create a math problem they could solve but the other AI tools would struggle with.

Sent from my mobile device. My sincerest and most heartfelt apologies for all of the autocorrections, as well as the semantically optimized yet contextually irrelevant phrasing that has been generously introduced by AI without my explicit intention or approval.
