It's only good for the man. It's not good for me. If you think I'm selfish, then you have no guarantee that it's the other man who would pay more and only I would get the discount.

It’s not good for anyone to pay more for anything. That doesn’t mean we create price control laws or make everything free lol

>That doesn’t mean we create price control laws or make everything free lol

I'm not suggesting anything of the sort.

Is this why grocery stores are so keen to get you to use their coupon app or hand them your phone number? I always refuse, but I always wondered what they do with the data.

The amount of "discount" is so much that they must be getting a large income stream from the data. Whenever I see something where the shelf sticker claims a lower price for "digital coupon" (meaning: use their app), I put the item back onto the shelf and move on. I'm willing to use the loyalty cards, but I am not willing to allow the sort of surveillance data that phone apps provide.

Margins on items at grocery stores is pretty thin. For them to be able to offer 50¢ or $1 off for items by using their app, that tells me that they are making more than that much from the data about me. My suspicion is that they're earning at least 10x that much from the data.

Buyers and sellers should be able to negotiate prices however they want. It is how markets have worked since the dawn of human trading. It would also be costly to police. If the problem is that a grocery store has a monopoly in an area, then that is a different problem fixed by adding grocery store(s).

Most pricing laws are built on the idea that this isn't OK. For example, I can't negotiate pricing directly with an automobile manufacturer. I have to go through a dealer so I am "protected".

That is a pretty good example of why these laws are not OK.

Is haggling an individualized price? What's stopping companies from allowing arbitrary bids on any item they can choose to reject? What if the future of the grocery store is eBay, a true nightmare.

Culturally, Americans do not haggle and do not to well in cultures where haggling is the norm. It would take a massive cultural shift before negotiating price is even close to normal. Part of this is why so many employees do poorly when negotiating salary during the interview process.

Sadly, this article doesn't explain how this "surveillance pricing" (which is just a scarier-sounding synonym for "dynamic pricing") would even work in a physical grocery store. Like, prices are displayed on the shelf for everyone to see. And they have to match what you pay at checkout. So how the heck would a grocery store even do this? And this law is specifically around grocery stores . Like, there was a big kerfu…

> So how the heck would a grocery store even do this? And this law is specifically around grocery stores.

Can't you just (in principle) use facial recognition cameras to determine who is approaching an item, calculate a "personalized" price and display it before they pick up the item, then make sure you match it at checkout? You could even use computer vision to only update price labels when people aren't looking at them, predict walking trajectories to pre-load prices and pre-resolve conflicts, and in ambiguous/low-confidence situations you could fall back on a default price.

This all sounds a bit like science fiction, but there is some prior art with Amazon's retail experiments, and it seems like this sort of thing is getting easier and cheaper all the time.

edit: some people have noted that you can have prices only visible viable via scanning qr codes, which makes this all much simpler. But I think you could do it with visible price labels too---you would lose some opportunities to jack up prices e.g. when multiple people are in close proximity to an item, but you could still profit in the (likely a majority of) situations where that's not the case.

It's so embarrassing that we banned forcing employees to work sixteen hour days without lunch breaks. Just go to another employer. Banning an employment model should be unconstitutional.

You're not even allowed to pay them in company scrip anymore!

Pricing will become increasingly adversarial. The Internet did too much to expose price differences to customers, so sellers are responding. Customers will need aggressive agents to price-shop on their behalf. Take hotel booking as one of the current nightmares of price visibility. Total price often isn't exposed until you show up at the hotel.

shopping, 2000: go to store. take item off shelf. hand cashier indicated amount of money. leave. shopping, 2030: use your personalized AI agent ($100/month subscription) to simultaneously impersonate a dozen clients across five different online shopping platforms with the goal of tricking the sellers' AI agents into thinking you're poorer than you are so that you can pay $5 for bananas instead of $25.

Its pretty obvious that a society intent on making capitalism work would enforce price transparency. If you want a productive society, you need efficient markets, and if you want efficient markets, you need to reduce information asymmetry, not maximize it. Hopefully the people in power recognize the positive impact they can make by preventing this awful future.

For individual discrimination (vs neighborhood or time of day), one way would be what Macdonalds does:

- raise all the prices

- have an app (with an account) to give personalized discounts

- use “AI” (or, just a regular program) to pick the optimal set of discounts per person, squeezing as much as you can out of them

One thing about "surveillance pricing" I've not seen addressed is that it destroys the usual model of demand curve. A given buyer may be judged to have the resources to pay a particular (high) price for a good, but other factors may be relevant: that buyer might need to save on good A in order to buy more of good B. The "surveillance pricer" would demand a higher price for good A because it has no information about n…

You might think that grocery stores in poor neighborhoods have lower prices than wealthier neighborhoods (because poorer customers are more likely to shop around for bargains). The opposite is true. Wealthy customers have the time, energy and money to be able to shop around. Poor people are stuck in "food deserts".

Some thought experiments for you:

1. This store is located between your employer and your home. The time is "right after typical working hours". The presumption that the algorithm can predict is that you're picking something up from the store to make for dinner, therefore you have no time to price shop and therefore we can charge you more because you have to have it now.

2. American shoppers tend to have very high brand loyalty. If you always buy product_A and never product_B, then the algorithm can charge you more for product_A because your demand is quite inflexible.

> I'm genuinely shocked that ill-defined "predatory pricing" is the issue we see in the news.

There are lots of evil people out there working very hard at extracting more than their fair share of wealth from others. Far too many people believe in the "Just World Hypothesis" - that "what goes around comes around". There are lots of random bad things and bad people that hurt innocent people. There might actually be some positive benefit that could come from surveillance pricing. However, once you've known or worked with some of the more predatory people then you'll see just how hard this technology can be used to screw others.

You’re supporting a price control law right now.
