james1071··on Why Is Productivity So Weak? Three Theories
Changes in prices are taken account of in the GDP calculation.
james1071··on Why Is Productivity So Weak? Three Theories
These issues are very well understood and incorporated into GDP.
james1071··on Why Is Productivity So Weak? Three Theories
No.
james1071··on Being a Developer After 40
Was he privileged when he was in Eastern Europe or only when he arrived in the US?
james1071··on How Measurement Fails Doctors and Teachers
Managements often like to use 'performance metrics' and other statistics as a means of providing cover for their own decisions.

They hide behind the numbers, which they have rigged, to avoid taking any blame.

james1071··on Why London Underground stopped people walking up the escalators
Formation walking is the solution.
james1071··on Why London Underground stopped people walking up the escalators
Yes, good joke but true.
james1071··on Why London Underground stopped people walking up the escalators
This is not correct.

The normal situation with escalators on the tube is that the flow of people onto the escalators is less than that which would cause a queue to build up.

That is not surprising, as the system has been designed so that there is sufficient capacity on the escalators to handle the flow of people.

However, at one or two stations during rush hour the situation can be different.

Sometimes the flow of people can be such that a queue builds up.

It is debatable, though, what would happen then if people walked on both sides of the escalator.

The queue would not move twice as fast, as people will not walk on side by side.

Another problem is that people with luggage take more than one person's width.

Standing two abreast may jam up the escalator, so that people are unable to get off easily at the top.

james1071··on Advanced economies are so sick we need a new way to think about them
That is a complete non sequitor, but never mind.
james1071··on Advanced economies are so sick we need a new way to think about them
You are talking as if construction were a large part of the economy.
james1071··on Beware “mathiness”: Algebra and data to reinforce ideological preconceptions
You don't understand what he has written.
james1071··on P values are not as reliable as many scientists assume (2014)
That is a separate issue.

The main problem with p-values is that, without further information, one cannot infer from them how likely it is that a result is genuine.

james1071··on Ask HN: Why do UK companies think that software development is cheap?
Just say no.
james1071··on Yanis Varoufakis resigns despite referendum no vote
Yes-I agree.
james1071··on U.S. GDP Shrank in Q1 2015
Debt overhang-takes a long time to work through.
james1071··on There’s more to mathematics than rigour and proofs
I am not so convinced of the merits of SMP, having done it myself.

It included some interesting things, but left out a lot of traditional pure and applied maths (especially mechanics).

james1071··on Ask HN: Why do managers tend to make more money than engineers?
There are obviously different possible reasons.

One is that the marginal product of a manager might be more than that of an engineer.

Another is that the manager is better at capturing value than are engineers.

These might amount to the same thing if there is a difference between actual marginal product and what is perceived within the company.

james1071··on “Cheating teachers go to jail. Cheating Wall Streeters don’t. What’s up?”
A friendly, helpful regulator will get job offers to work for the firms he is regulating.

A tough regulator will not.

james1071··on The Importance of Mathematics Courses in Computer Science Education
Agree-am sure that learning the hard stuff pays dividends years later.
james1071··on The Importance of Mathematics Courses in Computer Science Education
Think his point about MOOCS is that they don't filter the applicants, but let them fall by the wayside.

That is inevitable if the object is to grant a prestigious qualification but do not screen at entry.

james1071··on The Importance of Mathematics Courses in Computer Science Education
My comment is:

No-comp sci is not a branch of maths. Yes-you do need to know some maths to study it.

james1071··on Poor Kids of Silicon Valley
This doesn't seem to be that difficult a problem.

The solution is surely transitional payments to get people to relocate.

james1071··on 'Skunk-like cannabis' increases risk of psychosis, study suggests
I would be surprised if any correlation were spurious (assuming that the correlation is highly statistically significant and thus not a product of chance).
james1071··on Compound interest can help save for the future, or it can bankrupt the world
One of the things that investors soon learn is that achieving any sort of compound growth over a long time frame is virtually impossible.
james1071··on The Better Angels of Our Nature: Why Violence Has Declined (2012)
It might be that one factor is the decline in importance of manual labour.

Guys who are proud of their physical strength, which also gives them status and respect, may be more likely to resolve their differences through violence.

james1071··on Prostitution: is there anything wrong with selling sex?
Is there anything wrong with trolling hacker news?
james1071··on My experiment with smart drugs (2008)
Perhaps the drug made him a more prolific plagiarist.
james1071··on Virtually all TV comedies, from Seinfeld to South Park, follow a simple formula
You might explain this better to our American friends by reminding them of the fact that they have a highly commercial film and TV industry, where the profit and loss of individual shows is monitored very closely.

What works gets repeated and hence the industry is highly formulaic, with those in control of the money going for the explainable and repeatable.

That is not the case in other countries, where the lack of business sophistication has given more room for the creatives to flourish.

james1071··on What if Finland’s great teachers taught in U.S. schools?
It's always a pleasure to interact with people who respond emotionally, based on some other issue, than the one that is being discussed, so I congratulate you for your response.

I presume that you're upset with life being unfair, which it most certainly is.

It does not change the fact that lack of calories is not a significant factor in poor educational attainment in the UK.

There are also many reasons for a pupil not getting top grades-but being dragged into gang life by anti-intellectual peers is not one that ranks highly.

More common, in my experience, are boys wasting hours on playing computer games and smoking dope.

As for getting beaten up by entering into the wrong area-I don't see how that stops them from doing their homework in their bedroom.

james1071··on What if Finland’s great teachers taught in U.S. schools?
As I said, this is pretty much complete nonsense and a classic example of the phenomenon of American blindness to their problems.

Take your ludicrous assertion that healthcare costs will decline as a % of GDP over the next 20 years.

You are on another planet to the rest of us.
