Please provide a source if you have one. Dumping usually refers to the international trade context, I don't see how it could be applied in this case.

So are you against municipalities having the right to determine their own laws and regulations then? Just because you don't like the law doesn't mean you can ignore it.

My point is not whether or not the regulations should exist, in many cases they probably should not. I was just pointing out that having companies willing to operate in legal gray areas could have a distorting effect on the existing market.

The original question was what regulators could do, and an answer is to enforcing existing laws where applicable.

What does real estate have to do with the dollar? 1 dollar does not entitle you to any US land. Inflation is not driven by land or land development.

The value of the dollar is stable because people trust it to be stable and because there is a financial system that lets people use it for things they want to do. It fluctuates based on (money) supply and demand.

With Bitcoin you are trusting (or speculating) that someone will want to buy it from you in the future. You don't need to trust that no one will suddenly print more though.

I suspect Eugene Fama would say it is priced exactly right.

In the US predatory pricing only applies to companies who use their market power to earn above-competitive profits. So the earlier actions could only be dealt with by the FTC after they drove competitors out of the market and raised prices.

But another distortion is the regulatory arbitrage angle. Ride sharing companies that don't comply with taxi regulations, Airbnbs that don't have to follow hotel or zoning laws, etc.

I found it interesting that the employees of Renaissance finally convinced him to boot Robert Mercer. Simons has accomplished great things in mathematics, investing, autism research and math education. But he has also enabled a Bond villain to undermine our social fabric with disinformation, and I don't think he gets enough credit for that.

Fair, but I'm still not aware of any practical applications for "systems of equations" like the person I responded to mentioned. If you know any please share.

The determinant intuition for me is the signed volume factor for a change of basis. I've seen the combinatorial lattice path application and I'm sure there are more in other fields.

But not much reason I can see to have them feature so prominently in an intro linear algebra class. Better to spend more time with SVD for instance, which wasn't even covered in the first linear algebra class I took.

That is what Twitch does with "bits", it should definitely work here as well.

I don't understand, can you give an example?

For most of the classical applications determinants are computationally terrible compared to factorization methods, e.g. for matrix inverse elimination is O(n^3) and Cramer's rule is something like O(n!).

I saw a talk on this paper a couple years ago. https://arxiv.org/abs/1503.02531 The method is to train a smaller model on the predictions of a large model or ensemble. I'd be interested in knowing other techniques as well.

The difference is stocks vs. flows. $100 capex only shows up in year one, but the balance sheet goes up permanently (depreciating of course). When the parent mentions "level of infrastructure" it refers to the balance sheet account, which is why I mentioned P/B.

You are referring to Earnings/Share, not Price/Earnings. It doesn't matter much anyway, if they can make the same amount of money with less invested capital that should increase their metrics. And there are good tax reasons to prefer share buybacks over dividends as a way to return cash to shareholders.

I agree, I should have mentioned free cash flow. Of course the real answer is to look at many metrics and get a broad picture. But I doubt you are going to find a "value investing" reason to buy AMZN at these levels, it's clearly a growth stock.

P/E is a very meaningful metric. It's not that Amazon has infrastructure that matters, it's that they are reinvesting their earnings at a higher rate than other companies. If they returned capital to investors because they didn't have enough potential projects, then the investors would need to decide how to reinvest it.

Your comment about reflecting the infrastructure in valuation would lean toward looking at Price/Book Value instead. Amazon would look quite expensive on this measure as well.

Rybolovlev was the seller, the question is who is paying him and who did he buy it from for $127 million in the first place? At this high a price it seems more like money laundering than painting the tape, but who knows.

You are right, I miscopied from their website. 3 million trades, billions of shares daily. Whether market making is beating the market is mostly semantics, I was just responding to the guy who said they flipped heads 10 times and got lucky.

This article leaves more questions than it answers.

Is top 5% of patents really a good measure of scientist productivity as opposed to published articles or research awards?

Is outmigration more relevant than absolute residency numbers? If "top scientists" choose to start their career in a high tax state and don't move, they will not show up in this study.

What percent of this rather arbitrary group are professors, working at large corporations, or some other affiliation?

What is the effect of outliers? No sample size is given and the individual tax rate effect doesn't look very robust in the scatterplots. Does that fact that a large amount of patent law gets set in Eastern Texas influence this more than taxes?

Even for the corporate tax rate effect that does look like a positive correlation, the effect could be due to one or a few large organizations moving their R&D department.

This just seems like some half baked regressions that aren't seriously trying to understand the issue.

Sorry for the late reply. You are right that they are closely related, as revenue is a pretty important part of running a business.

But I find it useful to distinguish between them, as do most business schools. Mergers are part of corporate strategy that only somewhat involve marketing considerations. Advertising is marketing strategy that doesn't have much to do with corporate strategy. A decision to enter new markets would be in the overlap area.

Anyway I thought the original article was just vague consultant speak.

Another competitor is CoCalc (https://cocalc.com/) created by the SageMath developers.

A number of countries run these types of programs. https://en.wikipedia.org/wiki/State-sponsored_Internet_propa...

All promote their own propaganda and many also attack their rivals via sock puppets. As far as I know the only country using trolls to push general unrest is Russia.
