Solve for the (drone) equilibrium

A Patriot missile – usually priced at about $3m (£2.5m) – was used to shoot down a small quadcopter drone, according to a US general.

The strike was made by a US ally, Gen David Perkins told a military symposium.

“That quadcopter that cost 200 bucks from Amazon.com did not stand a chance against a Patriot,” he said.

Patriots are radar-targeted weapons more commonly used to shoot down enemy aircraft and ballistic missiles.

“Now, that worked, they got it, OK, and we love Patriot missiles,” the general said.

Addendum: The Chinese are experimenting with a radio wave gun to bring down drones.

Solve for the equilibrium are British people really like this?

The first self-driving cars to be operated by ordinary British drivers will be left deliberately unmarked so that other drivers will not be tempted to “take them on”, a senior car industry executive has revealed.

One of the biggest fears of an ambitious project to lease the first autonomous vehicles to everyday motorists is that other road users might slam on their brakes or drive erratically in order to force the driverless cars into submission, he said.

This is why the first 100 self-driving 4×4 vehicles to be leased to motorists as part of a pilot scheme on busy main roads into London will look no different than other Volvos of the same model, said Erik Coelingh, senior technical leader at Volvo Cars. The scheme will start in 2018.

Americans wouldn’t talk this way:

One driver interviewed for the survey said: “I’ll be overtaking all the time because they’ll be sticking to the rules.”

Another said: “They are going to stop. So you’re going to mug them right off. They’re going to stop and you’re just going to nip around.”

Addendum: Via Anecdotal, here is an Australian perspective:

Well, I am here to tell you: that’s OK. We’ve all had it drummed into us from infancy that humans bullying cars = bad.

But we can’t let our bourgeois notions of propriety in auto-human interactions stop us from letting out our inner Johnny from Karate Kid.

We must, rather, get on with the vital and necessary work of bullying, haranguing and insulting these contraptions every chance we get. Because I cannot stress this enough: these cars must not be allowed to develop self-esteem.

From another corner of the world, I can tell you that Kiwis do not drive as politely as they talk.

In early October, the [German] district government informed Sumte’s mayor, Christian Fabel, by email that his village of 102 people just over the border in what was once Communist East Germany would take in 1,000 asylum seekers.

His wife, the mayor said, assured him it must be a hoax.

Here is the NYT article, you will note that Herr Holger Niemann is enthusiastic about the new development; he is the lone neo-Nazi on the local town council.  By the way, the town has no stores, they had to install more pumps in the sewer system, and if I understand the article correctly Sumte has no permanent police presence.

At lunch lately we have been arguing how many immigrants can be taken in without seeing political backlash and eventually immigration reduction.  We’ll soon be seeing more data.

Most people assume a degree in the arts is no guarantee of riches. Now there is evidence that such graduates also rack up the most student-loan debt.

A Wall Street Journal analysis of new Department of Education data shows that median debt loads at schools specializing in art, music and design average $21,576, which works out to a loan payment of about $248 a month. That is a heavy burden, considering that salaries for graduates of such schools with five or fewer years’ experience cluster around $40,000, according to PayScale.com.

The story is here.  And here is some sad news in particular:

New York’s Manhattan School of Music had the second-highest median debt load, at $47,000. Graduates with up to five years’ experience earn an average of $42,700, according to PayScale.

Which school is number one?:

Among the 4,000 colleges and universities in the federal database, the Creative Center in Omaha, Neb., a for-profit school that offers a three-year bachelor’s in fine arts, had the highest average debt load, at $52,035. Median pay for graduates of the school with five or fewer years’ experience is $31,400, according to PayScale.com.

I say that’s a school in future financial trouble.

An environmental entrepreneur whose plan to dump iron in a patch of the Pacific Ocean was shelved four years ago after a scientific outcry has gone ahead with a similar experiment without any academic or government oversight, startling and unnerving marine researchers.

…The entrepreneur, Russ George, said his team scattered 100 tons of iron dust in mid-July in the Pacific several hundred miles west of the islands of Haida Gwaii, in northern British Columbia, in a $2.5 million project financed by a native Canadian group.

The job categories projected to grow over the next decade include nursing, home health care and child care. Of the 15 categories projected to grow the fastest by 2016 — among them sales, teaching, accounting, custodial services and customer service — 12 are dominated by women. These are not necessarily the most desirable or highest-paying jobs. But they do provide a reliable source of employment and a ladder up to the middle class. It used to be that in working-class America, men earned significantly more than women. Now in that segment of the population, the gap between men and women is shrinking faster than in any other, according to June Carbone, an author of “Red Families v. Blue Families.”

From Hanna Rosin, here is more.  And:

More important than the particular jobs available, which are always in flux, is a person’s willingness to adapt to a changing economy. These days that usually requires going to college or getting some job retraining, which women are generally more willing to do. Two-thirds of the students at the local community college are women, which is fairly typical of the gender breakdown in community colleges throughout the country.

Here is a description of one equilibrium:

The former Russell [a now-closed manufacturing firm] men are sometimes categorized by people in town as one of three types: the “transients,” who drive as far as three hours to Montgomery for work and never make it home for dinner; the “domestics,” who idle at the house during the day, looking for work; and the “gophers,” who drive their wives to and from work, spending the hours in between hunting or fishing.

Here is the short video.  Here is text with photos and another video.  Five Ukrainian women, in an Ukrainian art museum.  They are sleeping, or rather pretending to sleep, dressed up as Sleeping Beauty.  Men come along and kiss them, on the lips, with each man allowed only one kiss.  They have all signed legally binding contracts.  If a woman responds to a kiss by opening her eyes and “waking,” she must marry the man.  The man must marry the woman.

Who will kiss?  When do eyes get opened?

The museum gives out free breath mints.

…the Romney campaign went up with an ad just days after the Ryan pick, hitting Obama on the $716 billion figure.

“You paid into Medicare for years: every paycheck. Now, when you need it, Obama has cut $716 billion dollars from Medicare. Why? To pay for Obamacare,” the ad says. “The Romney-Ryan plan protects Medicare benefits for today’s seniors and strengthens the plan for the next generation.”

How the GOP ticket talks about Medicare is vitally important in Florida in particular, a competitive swing state with a high retirement-age population. Ryan is visiting the state for the first time today since he was named to the ticket, and will go to The Villages — billed as the largest retirement community in the world — with his mom.

But instead of wading into the policy details with which Ryan is most comfortable, Republican strategists said it would be far smarter for the Wisconsin lawmaker to focus on the Obama move to remove money from the Medicare trust fund and portray Republicans as the program’s savior.

Scott Sumner on the eurozone, wise throughout:

The eurozone excludes Norway, Iceland, Sweden, Denmark, Britain and Switzerland. That’s a fairly affluent group of countries.  The eurozone is shaped roughly like a pyramid, with Finland on top, and a wide base stretching from Portugal to Cyprus on the bottom.  Most of the weight if a pyramid lies in the bottom half, which in the case of the eurozone is mostly lower income countries like Italy, Spain, Greece, Portugal, Cyprus, and Malta…

The pyramid structure I referred to earlier is likely to get much worse as the eurozone grows over time.  And it seems to me that here you have a massive adverse selection problem.  Because of Abraham Lincoln, affluent states like Massachusetts can’t suddenly decide they want no part of our fiscal union, and would rather just reap the benefits of our large single market.  But Switzerland, Norway can and did make that choice.  Britain almost certainly would, and both Sweden  and Denmark might as well.  In contrast, Bulgaria, Romania and Croatia would like nothing more than to join such a union.  And all the likely future expansion of the EU is into areas further east, and much poorer than even Greece and Portugal.  Places like Armenia, Georgia, Ukraine (a country nearly the size of France) Belarus, Serbia, Macedonia, Bosnia, Moldova (the saddest place on Earth—even the name is depressing.)  And did I mention Turkey?  Indeed why not Russia at some distant point in the future?

That’s what some environmentalists said they feared when Planktos, a
California-based concern, announced it would embark on a private effort
to fertilize part of the South Atlantic with iron, in hopes of
producing carbon-absorbing plankton blooms that the company could
market as carbon offsets. Countries bound by the London Convention, an
international treaty governing dumping at sea, issued a “statement of
concern” about the work and a United Nations
group called for a moratorium, but it is not clear what would have
happened had Planktos not abandoned the effort for lack of money.

Here is the whole story.

What is the equilibrium in higher education policy?

That is the topic of my Bloomberg column, here goes:

Critics of the policy see it as rewarding Democratic supporters and interest groups, including university faculty and administrators but most of all students. This perception, regardless of whether it’s true, will influence political behavior…

Republicans, when they hold political power, are likely to strike back. They may be more interested in draining the sector of revenue. The simplest way of doing this would be to limit tuition hikes in state universities. De facto tuition caps are already common, but they may become tighter and more explicit, especially in red and purple states. Such policies might also prove popular with voters, especially during a time of high inflation.

A second set of reforms might limit the ability of public universities to spend money on hiring more administrators, including people who work on so-called DEI issues. Given the fungibility of funds, and the ability of administrators to retitle new positions, such restrictions may not be entirely enforceable. Still, they would mean less autonomy for public universities as policy in many states tried to counteract their current leftward swing.

Another possible reform could tie funding for a school or major to the future earnings of graduates. That likely would penalize the humanities, which already tend to be one of the more politicized segments of the modern university…

Longer-term, a future Republican administration might decide to restructure the entire system of federal student loans. How about making student loans dischargeable through normal bankruptcy proceedings? That might sound like a pretty unremarkable idea to most voters, and many economists, including Larry Summers, favor it. It would also allow for some measure of debt relief without extending it to the solvent and the well-off.

Still, the long-term consequences of this reform would probably lead to a significant contraction of lending. Most enrolled students do not in fact finish college, and many of them end up with low net worth yet tens of thousands of dollars of debt. (By one estimate, the net worth of the median American below age 35 is $13,900.) So the incentives to declare bankruptcy could be relatively high. This would make federal student loans a more costly and less appealing proposition. Private lenders would be more wary as well. Higher education would likely contract.

The net effect of the president’s loan-forgiveness initiative — which is an executive order and thus does not have an enduring legislative majority behind it — could amount to a one-time benefit for students, no impact on rising educational costs, and the intensification of the culture wars over higher education.

Sad but true.

What does equilibrium look like for the book business?

Adam Davidson offers some interesting remarks.  My take is a little more radical.  I expect two or three major publishers, with stacked names (“Penguin Random House”), and they will be owned by Google, Apple, Amazon, and possibly Facebook, or their successors, which perhaps would make it “Apple Penguin Random House.”  Those companies have lots of cash, amazing marketing penetration, potential synergies with marketing content they own, and very strong desires to remain focal in the eyes of their customer base.  They could buy up a major publisher without running solvency risk.  For instance Amazon revenues are about twelve times those of a merged Penguin Random House and arguably that gap will grow.

There is no hurry, as the tech companies are waiting to buy the content companies, including the booksellers, on the cheap.  Furthermore, the acquirers don’t see it as their mission to make the previous business models of those content companies work.  They will wait.

Did I mention that the tech companies will own some on-line education too?  EduTexts embedded in iPads will be a bigger deal than it is today, and other forms of on-line or App-based content will be given away for free, or cheaply, to sell texts and learning materials through electronic delivery.

Much of the book market will be a loss leader to support the focality of massively profitable web portals and EduTexts and related offerings.

There is this funny thing called antitrust law, but I think these companies are popular enough, and associated closely enough with cool products — and sometimes cheap products — to get away with this.

The equilibrium (with apologies to Daniel Klein)

On September 5, the first Sleeping Beauty in Polataiko’s exhibition awoke to a kiss from another woman. Both of them were surprised. Polataiko shot photos of them laughing and looking at each other. Then he posted the images to his Facebook profile, where he has been live-blogging the entire event. Now the Sleeping Beauty must wed her “prince,” thus queering the historically heteronormative fairtytale. Gay marriage is not allowed in the Ukraine, however, so these two women will have to wed in a European country that does allow for same-sex marriage.

Here is more.  I believe that none of you had solved for this equilibrium.  For the pointer I thank Eapen.

The political economy of Kansas fiscal policy (from the comments)

MR commentator Patrick L. has a go at it:

OK I’ll bite.

In nominal terms, between 2002 and 2012 state receipts grew 50%. Inflation in this period was 28%, and probably significantly lower for Kansas, while population growth has only been about 10% since 2000. Even the “low” 2014 receipts are $1.5 billion more in revenue from when Sebelius first took office and the government started rapidly growing. In the past 15 years expenditures have grown over 50%, exceeding $6 billion today. The shortfall is $300 million, or about 5%. While the growth of the Kansas government in the past 15 years is smaller than other governments in the country, it still explains the shortfall. We can justify this increase by saying that education and health are rising faster than everything else, but that is not a revenue problem. Tax rates have to rise because education and health costs are growing faster than our economies. That says nothing at all about the optimum size of taxation for state governments with regard to growth, jobs, or even revenue. The tax and spending levels Brownback choose would have been adequate ten, maybe even five years ago. With a bit of luck, he could have ignored the shortfall because of variance, which for receipts can be a few hundred million a year.

Republicans should be wise enough to not depend on luck, and they should be wiser predicting how trend lines go. Cutting the size of government was never a serious option.

I haven’t looked at the votes in depth, but it looks like a classic case of urban // rural split that typically troubles the state’s politics. Just under half the state’s population lives around Kansas City or Wichita, which are both five times than the next largest city. These places have as many votes as the rest of Kansas combined, but their needs are radically different.

Rural Kansas has two unique problems. First, there’s the problem of population collapse, which all farm states are seeing. What few children are born move out when they come of age and new people are not moving in. Fixed costs like “We need at least one school building” or “We need at least one teacher per grade” start to add up for small towns of 1000 or less. Those are the obvious problems, not to mention any number of federal or state concerns dealing with food, medical, or disability services that have to be met. As a matter of geography, 98% of the state is rural, and I think I heard 25% of the state is in towns less than 2500 – with over 400 municipal governments servicing less than 1000 people it’s probably the highest per capita in the country (This is FIVE times the national average).

This is a non-trivial growing problem related to scale government services that has been an issue of intense legal debate in the state. Wichita School District’s scale is such it can use its buses to deliver free or low cost lunches to children in the summer. Small cities don’t have buses. Is that fair? How should taxes be structured to compensate? The only political viable solution to this problem has been to spend more money. If all the small towns could magically consolidate into a super smallville, taxes would (back of the envelope) be 10-15% lower.

Government services to low population areas are subsidized by high population areas, and it costs much more to deliver the same services to small towns. The US Postal Service paid for delivery to small towns across the country by charging monopolistic prices on first class letter mail in cities (Which cost almost nothing to deliver). NPR’s national budget mostly goes to setup stations in small towns. The small towns in Kansas are both relatively and in many cases actually getting smaller, older, and poorer. They are costing more and delivering less.

The other problem is that some rural areas are *growing*, but they’re growing because of immigration attracted to the agriculture and food packaging industries. Which is not the same as growing from a resource boom which can be taxed heavily to compensate. Liberal, KS is the largest per capita immigrant community in the United States. While this influx of people is necessary for the health of these places, the new population has more expensive demands on government services and pays less in taxes. Some of these small towns are the same ones that a decade ago were collapsing. Services and infrastructure might have been allowed to lapse or removed, and now rapidly needs to be replaced. That’s expensive! In the long run this problem might replace the first problem, but for now it’s the worst of both worlds.

The economy of the small cities is based largely around food production, which mostly can’t move, and food packaging, which probably can’t for logistical reasons. These places are poorer, getting relatively poorer per capita, and demanding more in services both directly (immigration / aging) and through scale issues. Their populations are either getting very old or very Hispanic, or both.

In contrast, Kansas City is a stable metropolis whose economy depends on manufacturing is built around a national centralized hub for trains. It also has some finance and telecom sprinkled in, though those guys can probably go anywhere. Wichita, is a moderately growing city based around aircraft manufacturing. When state taxes can’t provide enough government services, local taxes for these areas easily rise to compensate. Their economic concerns are how to stop businesses from going across the border to Omaha, Oklahoma City, Tulsa, Springfield, or Kansas City, Mo – places which are functionally identical and just as close. Given their dependence on manufacturing, they also have to consider movement across international borders to China and Mexico. Their demography is much closer to the national averages rather than the extremes. They are large enough that they can take advantage of scaling for government services, without being so large that there is decreasing actual returns. I don’t have figures, but I’d guess income rates in the urban areas to be between 150 and 200% those of the rural areas, which are themselves typically around 2/3rds the national average. This is an industry effect, a farmer in Kansas City and an aeronautical engineer in Greensburg, KS would not make much money. The cities are richer, but they’re richer because they have industries that are becoming increasingly easier to move.

On a political level, normally cities become more liberal, and poorer as you go deeper into the city – a leftover of 19th century industrialization competing against 20th century transportation. Deep urban cores produce these deep blue constituencies that act as checks on conservative suburban rings. In some states this manifests itself as a coalition between the poor rural areas and the poor urban areas against richer suburban areas allowing normal American class politics to balance itself. Cities produce political equilibrium: The richer and denser it becomes, the more liberal, which pushes more money and voters to suburbia, diluting the power. In short, declining rural power (D) and rising urban power (D) offset each other, but rising urban power (D) enhances suburban power (R), and so at a state level you get a balance.

The problem is that the inner core of Kansas City is in Missouri, so Kansas only gets the rich (Republican) suburban ring and a tiny blue part. Typical democratic concerns like maintaining a progressive tax structure can’t really find a foundation. While Wichita also has an urban core that does provide a Democratic representation, the city isn’t constrained geographically by anything (No ocean, mountain, lake, and transportation goes around, not through, the city) means concentration, an ingredient for populist politics, is lessened. The city spreads, and the poor can easily move up the class structure by moving further and further out. Wichita has half the population density of Syracuse and two thirds that of Madison, two close sized metropolitan areas. I haven’t done a county level comparison, but I suspect that Sedgwick has half the density of the ‘average American county with half a million people’ in it. There are other places in America like that, but guess how they vote.

Nor are either cities big university cities, like Madison or Boston. The two big universities in the state are in the small towns of Lawrence and Manhattan, which are quite separate from the rest of the state. Urban centers are places of “Commanding Heights” industries, like health and education that can’t easily move, but Wichita and Kansas City are based around manufacturing.

The political outcomes are not that surprising at all. There is nothing ‘the matter with Kansas’. The power structure easily shifts between slim majorities formed from predominately suburban populations who are wealthier, and whose jobs are most likely to move, and slim majorities formed from the small urban cores and rural parts of the state.

There’s no possible political coalition that you could form that would pass a constitutional amendment allowing a floating balanced budget over a 10 year period. Nor are the populist pressure strong enough to push against regressive taxation. You have ‘fiscal hawks’ in the rural areas who never vote for cuts, and suburban conservatives who never vote for taxes. When the storm gets too bad, they vote a nice moderate democrat in to raise taxes and crack down hard on whatever (Non manufacturing / agricultural) big business they can put pressure on. Obviously something that can’t move easily like Health Insurance.

In summery, this really is an issue of Urban vs Rural politics. Unlike other cities, the kind of industries around Kansas City and Wichita can move. The jobs in the rural areas can’t. The rural areas require more per capita government services, and the urban areas have more money. They both have half the vote. Solve for equilibrium.

== As for the deal:

It’s mostly a .4% sales tax increase, which is less than some of the more fanciful projects done by local governments in the past 15 years, which have included sports arenas, loans to movie theaters, and waterfront improvement. A half cent increase in sales tax does move the state into the top 10 for the country, but the overall tax burden is still quite low. The real problem is that city/county sales taxes are a function of distance from Wichita, and the inverse of population. The smaller your city, and the farther you are from Wichita, the more the county depends on sales taxes. In places like Junction City, this could put the sales tax close to 10%! The real disparity is going to be at the border towns: After the change there will be a .7% difference between KC, KS and KC, MO, though I bet the Missouri side will raise taxes to compensate. After the increase, there’s a 1.5% difference between Pittsburg, KS and Joplin, MO – big enough that I could see some people consider driving for purchases more than $300 (Biweekly grocery shopping for a large family?), especially if retailers on the Missouri side are not dumb. As a general rule, the money and the shopping is on the Kansas side of the border, so stuff isn’t going to transition immediately, but I expect some Laffer curve effects here for local governments, and I would hope they’ll respond by dropping taxes to compensate.

This is probably WHY such a deal was able to pass. Most of the damage goes on the poor and rural parts of Kansas, which is where most of the balance budget hawks are. The rich living near Kansas City will have the easiest time dodging the increase and avoid it more often. A regressive tax, but an efficient one.

As for the other parts of the deal, $90 million in itemized deductions are being removed. I don’t actually think this will amount to much, since there aren’t many itemized state deductions left. What remains are things like adoption, historical preservation, or disabled access. I don’t see much money coming in this way, and the state will almost certainly reverse itself the first chance it gets (As it did the last time it got rid of the adoption credit).

Whew!
