Models are not inherently scientific, just because something is trying to make predictions doesn't make it scientific. May I ask, what do you think of economic models? Would you call them scientific? They are using similar underlying e

Perhaps you've never studied chaos theory? Complex systems are notoriously hard to model despite the underlying process being deterministic. Why do you think we keep having recessions? We know where every dollar is at every point in ti

The very fact it is held to a better standard means it is more responsible when it mucks up. If NY Times is the vanguard of journalism, would you not find it atrocious the precedent they set in partisanship and misrepresentation of the peop

The data you see is biased negatively - you have recruiters fees for one sitting above the salaries you see. People complaining on glassdoor are probably not the highest paid team members. You also have the fact that people who are paid wel

Dealers need bbg, the social network in bbg chat drives some network effects, there's also a bit of tradition involved too. They tend to have less data issues than most but there's plenty still there. Analysts and research roles a

Did you intend for your username to give away where you work? Unless of course Odecee is not the firm here. You should probably check your professional indemnity insurance is all sorted out if you are a contractor.

No that's not the cause, globally fees are coming down across the industry and that is putting pressure on salaries.

I wonder if 'fake news' will become the next excuse to encroach on our liberties just like how 'terrorism' is used.

Academia relies on students to exist, the students are the customer not the workers - so the power is a lot more in favor of the grad student, not that academia itself is any more noble or humane. I doubt academia is inherently any more hum

Uber doesn't form monopolies as far as I can see, everywhere there seems to be a competitor or two, so that pricing pressure will keep Uber in check. I'm not sure why you think Uber has the power.. they have a lot of cash and firs

Perhaps I need to clarify, these systems are chaotic hence the difficulty in modelling them, I didn't mean to imply anything political. https://en.wikipedia.org/wiki/Complex_system

It's a failing of the industry to treat nutrition as cause and effect when the body is clearly a complex system. Then again, it's hard to pick a complex system that we do model properly.. the economy, the climate, the body, etc..

My comment was half tongue in cheek, but it's still accurate. US government debt has to be paid in USD, it doesn't matter what other assets they own, that can only be used to buy USD. Unless you barter with bondholders and have th

The converse is allowing US companies to break the law in other jurisdictions. Imagine if Valve just kept the money and didn't deliver the games at all? Surely you have to comply with the law everywhere you operate.

It sounds to me like what he's building is a lot closer to a custom version of an issue tracking product than an artificial version of Dalio's brain. Is this accurate?

A $25 hold for a fare that might be $15 doesn't sound unreasonable? Is ride-sharing that big of a cost for your day to day?

How exactly do you think the performance is made public, if the fund doesn't want it to be? This isn't about illuminati, this is just logic. You can't hide what you're doing from the institutions you have to deal with, b

The article seems to use the labels 'insider' and 'hacker' to contrast the intent of the two, when the labels should be just used to define their circumstances. Both Snowden and Ellsberg appear to have done a good job at

It depends on your definition of reliability. Is driving a car reliable? There's no way of knowing it will crash but that doesn't stop you from getting in one. You see it as a problem, if you are used to the idea of earning money

"Algotrading" generally refers to execution algorithms only, despite popular culture's interpretation. When the funds portfolio is decided based on a system your fund is systematic. It's an important distinction.

Academia doesn't pay that much attention to the real world. Most of the papers out there are rubbish and would be considered junior level work, except with way too much detail. There are pretty much no econ papers that would describe w

He's wrong because he's assuming the average result of the zero-sum game is the only result you can have. It's a simple fallacy most people with a statistics background understand, but the average journalist doesn't. Say

Or perhaps there isn't causality either way. For example, perhaps good management tends to produce both happy employees and successful companies.
