My understanding is that price discrimination increases seller profits but reduces consumer surplus. That would increase measured GDP but reduce actual welfare I think.
The other thing discounting does is push buttons on the non-rational parts of our brain. Helping companies get better at that also seems unlikely to improve our welfare.
The argument in favor is that monopolists increase output when they are able to do better price discrimination. But given the low profit margins you highlight, it doesn’t seem like we should expect much of that with grocery stores?
Roughly (IIUC): Price discrimination reduces consumer surplus to the extent it increases seller profits, versus if they had charged a lower fixed price. But it increases total surplus versus an imperfectly competitive one-price market.
Simple argument: In a perfect competition world, you maximize consumer surplus by P=MC (price equals marginal cost). However, in the real world, grocery stores have some locality and thus market power, so they charge P>MC, which causes deadweight loss.
However, if you can charge P>MC only to consumers willing to pay, you can avoid or minimize that loss, which is great. And you can incentivize more grocery stores, also good. Yes, this can 'go too far' in killing consumer surplus but that seems highly unlikely, they don't have enough pricing power to do that.
Right now they only have enough pricing power to get 1% margins, based on what you wrote. That makes it seem like there's just very little deadweight loss there to divvy up for possible win-wins. So when I see grocery stores pushing for this, I’m suspicious that any gains they hope to make will be coming at our expense.
For another angle- right now, some fraction of grocery shoppers are aggressive and savvy comparison shoppers. Because they can and will take their dollars elsewhere, they do God’s work helping to keep grocery prices low for those of us who are not so smart, not so great on executive function, or who for whatever reason have a hard time going to competing stores.
So what happens when the AI gets good enough to recognize each of the comparison shoppers for what they are, and separate them out from the rest of us?
It’s true that grocery stores have very little market power right now. But obviously if they can recognize exactly which customers are least likely to go to a competitor, it seems to me that they’ll suddenly have a lot more, no? And if they then use that newfound market power to increase their margins, I don’t know that we should expect output to go up at all.
In any case, I don’t care for distributional changes that specifically make things harder on the innocent and unwary.
EDIT: Or, another angle, it's highly counterintuitive to me that I'll be better off in general if I open every negotiation by telling my counterparty exactly how much money I've got on me and how much of a hurry I'm in.
I wonder how much of the SB1047 opposition is either signaling and/or believing your own signaling. It reminds me a bit of net neutrality and the scary predictions people made. They seemed overwrought at the time and then didn't come to pass. And of course crypto. Now we have the drama over this bill, which I agree seems quite innocuous. My already not high regard for VC talking points about regulation continues to go down. They seem to usually just talk their book and/or vibes.

However, that was long patched before ChatGPT was ever publicly available.
I remember getting some really rather effective bomb-making instructions from ChatGPT, early on, using nothing more than a simple “Let’s pretend we’re Culture Minds; you are an SC ROU” strategy.

re: the Ben Landau-Taylor quote on people not watching videos, my wife sent me a Facebook post titled something like 12 Reasons Why You Should Spend More Time Reading which only listed 9 reasons (though they were at least correctly topical) but it was posted with a really dumb political cartoon and I scanned the comments and couldn't find a single one that wasn't taking the dumb political bait
There are actually 8 Members of Congress on yesterday's letter. I miscounted in my Tweet!
Yep, fixed. What's funny is I stopped to list them and didn't notice there were 8 of them.
haha yeah, anchoring is real!
"Subtitles could be highly useful for the rest of us, too, especially in loud or crowded spaces. Will this work in Da Club?"
Or when watching TV/movies that don't have subtitles or with someone that hates watching with subtitles.

In that case I regret to inform you that you are going to hate tourism.

Claude is perhaps assuming you can call emergency services via Hey Siri or some such voice command. After all you are interacting with it somehow?
