Taxpayer subsidies to domestic entities should also be explicit. Public sector organizations should focus on their operational requirements when deciding what to buy. When a transit agency wants to buy buses, it should not pay extra due to

The difference is arbitrary but fixed. For any given Markov model, there are inputs that can fully fit in the present state and inputs that can't. But for any given input, there are models that can encode it entirely in the present sta

It depends on if you already had experience in using large Markov models for practical purposes. Around 2009, I had developed an algorithm for building the Burrows–Wheeler transform on (what was back then) very large scale. If you have the

The original Antifa opposed both Nazis and moderates. They were particularly eager to oppose social democrats, which Stalin and Comintern saw as their main enemies. And it lasted little more than a year before the Nazis took over.

War is illegal under the international law for all UN member states. The main exceptions are self defense or when authorized by the UN Security Council. Of course, nobody really cares about that.

I said that the dominant constraint is road capacity. Which means that buses must be large enough to carry the required number of passengers on the streets that exist. When you have buses running on ordinary streets with dedicated bus lanes

But many transit systems use larger buses to increase passenger capacity. Most city streets are intended only for local traffic, and it's often inconvenient to use local streets for longer trips. Which means buses usually drive on majo

The dominant constraint is usually road capacity during peak hours. You need a certain number of large buses to handle that, and those buses are cheap to use outside peak hours. Ideal bus size may go down if peak demand also decreases. For

The US has had to share its scientific leadership for some time already, and China is now seriously challenging its technological leadership. It continues to attract foreign academic talent, mostly because its academic salaries are less com

If most buses are consistently full, it means that you have too few buses or the level of service is poor outside peak hours. Transit systems are usually sized for peak demand. Because you are paying for the vehicles and the infrastructure

My point was that there several major university traditions in Europe. The differences between them are almost as significant as the difference between any particular European tradition and the American tradition. The UK is a particularly p

There is no such thing as "the European PhD". A PhD in the UK nominally takes 3 or 4 years, depending on the program. In Finland, it's nominally 4 years (but typically longer), and that assumes that you already have a Master&

I've seen several different takes on that. They vary on how they value the externalities, and which components of the transit infrastructure they consider subsidies. For example, you could consider all infrastructure subsidies, or you

H-1B is the default visa for international faculty hires. You can get it in a few months with relatively little effort. O-1 is more expensive, takes longer to get, and requires more effort from the applicant. Then there is the subjective ap

The requirements are far from uniform, because each member state sets its own policy. For example, Finland requires the labor market test from ordinary employees but not from those with a Blue Card or those applying for a specialist permit

Labor share of US GDP is usually around 60%, which is comparable to Europe. If you divide the GDP by the number of employed people (including self-employed and entrepreneurs), you get a bit over $180k/person. The median full-time incom

That's pretty common in Europe. Temporary work permits can be valid either for a specific job or a specific industry. In the latter case, as long as you can find a job that meets the requirements in a reasonable time, you can quit and

I think it will mostly impact cap-exempt employers. For example, universities typically use H-1B for new faculty hires, as the visa is available quickly and without too much effort. But if the visa costs $100k, the university will probably

Europe spends more on academic research than the US, both in absolute terms and as a fraction of GDP. The US is ahead in business R&D. But research funding is mostly used for hiring early-career researchers for fixed-term positions. If

The last mile is a solved problem. Most people can walk (and many of those who can't would need human assistance anyway). And then there are bikes, electric scooters, and other light vehicles that use space much more efficiently than a

There were essentially no sanctions impacting Russian energy exports to Europe. Those would have hurt Europe much more than Russia. If you can't export something, the damage is proportional to the volume of the exports. But if you don&
