The Rotten Kid theorem?

According to Adecco, nearly a third of parents are helping their kids find work, and nearly one in ten are taking them to job interviews.

…Three percent of recent college grads say their parents have actually sat in with them during interviews, and one percent claim Mom or Dad wrote their thank you notes afterwards.

Nearly one in four say they would not take a job they were otherwise interested in if they could not make or receive personal phone calls at work. Twelve percent say they wouldn’t work at a place that wouldn’t let them check in on Twitter or Facebook. Finally, my favorite, five percent — one in 20 recent grads — say they wouldn’t take a job where they couldn’t shop online, and the same amount would say no to employment where they couldn’t check sports scores.

The story is here, and for the pointer I thank John Chilton.

The Myth of Chinese Meritocracy

No doubt you have heard how the leadership of China is meritocratic and composed of technocrats with PhDs. Minxin Pei suggests that there is less than meets the eye.

…Contrary to the prevailing perception in the West (especially among business leaders), the current Chinese government is riddled with clever apparatchiks like Bo who have acquired their positions through cheating, corruption, patronage, and manipulation.

One of the most obvious signs of systemic cheating is that many Chinese officials use fake or dubiously acquired academic credentials to burnish their resumes. Because educational attainment is considered a measure of merit, officials scramble to obtain advanced degrees in order to gain an advantage in the competition for power.

The overwhelming majority of these officials end up receiving doctorates (a master’s degree won’t do anymore in this political arms race) granted through part-time programs or in the Communist Party’s training schools. Of the 250 members of provincial Communist Party standing committees, an elite group including party chiefs and governors, 60 claim to have earned PhDs.

Tellingly, only ten of them completed their doctoral studies before becoming government officials.

Simply put, Chinese institutions are not as good as those in say Mexico. Thus, China will not overtake Mexico in terms of GDP per capita any time soon, hence Chinese growth rates will fall. All we are seeing today is the logic of the Solow model in action.

Bertrand Russell’s 10 Commandments for Teachers

  1. Do not feel absolutely certain of anything.
  2. Do not think it worth while to proceed by concealing evidence, for the evidence is sure to come to light.
  3. Never try to discourage thinking for you are sure to succeed.
  4. When you meet with opposition, even if it should be from your husband or your children, endeavour to overcome it by argument and not by authority, for a victory dependent upon authority is unreal and illusory.
  5. Have no respect for the authority of others, for there are always contrary authorities to be found.
  6. Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.
  7. Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
  8. Find more pleasure in intelligent dissent that in passive agreement, for, if you value intelligence as you should, the former implies a deeper agreement than the latter.
  9. Be scrupulously truthful, even if the truth is inconvenient, for it is more inconvenient when you try to conceal it.
  10. Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.

The Big Easy’s School Revolution

Interesting op-ed in the Washington Post on schools in New Orleans.

…the levees broke and the city was devastated, and out of that destruction came the need to build a new system, one that today is accompanied by buoyant optimism. Since 2006, New Orleans students have halved the achievement gap with their state counterparts. They are on track to, in the next five years, make this the first urban city in the country to exceed its state’s average test scores. The share of students proficient on state tests rose from 35 percent in 2005 to 56 percent in 2011; 40 percent of students attended schools identified by the state as “academically unacceptable” in 2011, down from 78 percent in 2005.

….Most of the buzz about the city’s reforms focuses on the banishment of organized labor and the proliferation of charter schools, which enroll nearly 80 percent of public school students, up from 1.5 percent pre-Katrina. But what really distinguishes New Orleans is how government has re­defined its role in education: stepping back from directly running schools and empowering educators to make the decisions about hours, curriculum and school culture that best drive student learning. Now, state and school-district officials mostly regulate and monitor — setting standards, ensuring equity and closing failing schools. Instead of a traditional school system, there is a system of schools in what officials liken to a fenced-in free market. Families have more choice about where their children can best succeed, they say, and educators have more opportunity to choose a school that best aligns with their approach.

The population of New Orleans changed pre and post-Katrina so it’s difficult to compare pre and post-Katrina test scores; although given the state of the schools pre-Katrina it’s hard to believe that the schools have not greatly improved. What really drives innovation, however, is not a simple substitution of private for public but a system substitution of competition for monopoly. The key therefore is to expand charters and voucher programs.

The state of Louisiana just passed a voucher program that although limited to poor and middle class students in failing schools will offer as many as 380,000 vouchers to be used at private schools or apprenticeships. Indiana has passed a potentially even larger program that would make about 500,000 students voucher-eligible. Keep in mind that at present there are 50 million public school students and only 220,000 voucher students nationwide.

My ideal program would fund students not schools and would make vouchers available to all students on a non-discriminatory basis. We are far from that ideal but we are slowly moving in the right direction. Charters and the expansion of voucher programs around the country are starting to bring more competition, dynamism and evolutionary experimentation to the field of education.

The Armchair Economist-Revised Edition

The Armchair Economist includes my favorite line in all of popular economics:

Economic theory predicts that you are not enjoying this book as much you thought you would.

I laugh every time I read that line and I think what a brilliant opening to an essay on auction theory and the winner’s curse!  And then I think, but in fact I am enjoying this book more than I thought!

I first read Landsburg’s book some twenty years ago and dipping into the revised edition over the weekend I can see how influential The Armchair Economist has been on my own teaching and writing, particularly Landsburg’s wonderful and deep essay, Why Prices are Good: Smith v. Darwin. Around 1997, the Armchair Economist also inspired my (now) colleague Bryan Caplan to create a listserv to discuss economics with a small cadre of like minded readers. Many of the people on that listserv would later become well-known econ bloggers. My history makes me assume that everyone has read The Armchair Economist, after all, all my friends have read The Armchair Economist! More rational reflection tells me that time and the flowering of popular economics means that there is a whole new generation of readers ready to be delighted and inspired.

California fact of the day

Data available from the UC Office of the President shows that there were 2.5 faculty members for each senior manager in the UC system in 1993. Now there are as many senior managers as faculty.  Just think: Each professor could have his or her personal senior manager.

And there is this:

A report on administrative growth by the UCLA Faculty Association estimated that UC would have $800 million more each year if senior management had grown at the same rate as the rest of the university since 1997, instead of four times faster.

What could we do with $800 million? That is the total amount of the state funding cuts for 2008-09 and 2009-10, and four times the savings of the employee furloughs. Consider this: UC revenue from student fees has tripled in the last eight years. The ratio of state general fund revenue to student fee revenue in 1997 was 3.6:1. Last year it was 1.9:1. If we used that $800 million to reduce student fees, the ratio would go back to the 1997 value. To put another way, it could pay the educational fees for 100,000 resident undergraduates.

Thiel’s Law

Thiel’s law: A startup messed up at its foundation cannot be fixed.

That is from the new section of Peter’s lecture notes, recommended of course.  To pose a simple question, how many other people are there in the world you would rather listen to?  Does that not mean Peter is one of the seminal public intellectuals of our time, albeit working through some non-traditional media of communications?

The factory farm?

There are no professors in Virginia Tech’s largest classroom, only a sea of computers and red plastic cups.

In the Math Emporium, the computer is king, and instructors are reduced to roving guides. Lessons are self-paced, and help is delivered “on demand” in a vast, windowless lab that is open 24 hours a day because computers never tire. A student in need of human aid plants a red cup atop a monitor.

The Emporium is the Wal-Mart of higher education, a triumph in economy of scale and a glimpse at a possible future of computer-led learning. Eight thousand students a year take introductory math in a space that once housed a discount department store. Four math instructors, none of them professors, lead seven courses with enrollments of 200 to 2,000. Students walk to class through a shopping mall, past a health club and a tanning salon, as ambient Muzak plays.

I reserve judgment, but note this:

…Virginia Tech students pass introductory math courses at a higher rate now than 15 years ago, when the Emporium was built. And research has found the teaching model trims per-student expense by more than one-third, vital savings for public institutions with dwindling state support.

“When I first came here, I was like, ‘This is the dumbest thing ever,’” said Mike Bilynsky, a freshman from Epping, N.H., who is taking calculus. “But it works.”

No academic initiative has delivered more handsomely on the oft-stated promise of efficiency via technology in higher education, said Carol Twigg, president of the National Center for Academic Transformation, a nonprofit that studies technological innovations to improve learning and reduce cost. She calls the Emporium “a solution to the math problem” in colleges.

It may be an idea whose time has come. Since its creation in 1997, the Emporium model has spread to the universities of Alabama and Idaho (in 2000) and to Louisiana State University (in 2004). Interest has swelled as of late; Twigg says the Emporium has been adopted by about 100 schools.

Does Not Compute

Steven Salzberg from Forbes is right about this:

Wow, no one saw this coming.  The University of Florida announced this past week that it was dropping its computer science department, which will allow it to save about $1.7 million.  The school is eliminating all funding for teaching assistants in computer science, cutting the graduate and research programs entirely, and moving the tattered remnants into other departments.

Let’s get this straight: in the midst of a technology revolution, with a shortage of engineers and computer scientists, UF decides to cut computer science completely?

Salzberg, however, is critical of Florida Governor Rick Scott for cutting university funding overall (Scott famously decried anthropology degrees in favor of STEM). Salzberg also finds it “unintentionally ironic” that in announcing a new polytechnic just two day ago Gov. Scott said:

“At a time when the number of graduates of Florida’s universities in the STEM [science, technology, engineering, and mathematics] fields is not projected to meet workforce needs, the establishment of Florida Polytechnic University will help us move the needle in the right direction.”

Rather than ironic I see this as illustrating how university incentives are not always aligned with those of the Governor or with the social interest. As Governor, Scott can more easily direct new funds towards STEM than tell entrenched university bureaucracies how to reallocate funds among existing programs. In particular Scott wants to promote STEM and computer science graduates for the externalities they produce but universities don’t get paid for producing externalities they get paid based on student enrollment. Thus, this is not surprising:

…Meanwhile, the athletic budget for the current year is $99 million, an increase of more than $2 million from last year.  The increase alone would more than offset the savings supposedly gained by cutting computer science.

How to get stuff done

This is a good discussion, I agree with most of it, for most people.  Here is one bit:

The hardest part is often just starting. I’ve found that it’s especially hard for me to start when a task is difficult or complex. The more importance and weight a certain activity has in my life or business, the more I seem to put off starting.

However, if I can just get moving on it, even for a few minutes, it tends to get easier.

Because I know this about myself, rather than setting the intention to finish something, I resolve myself to start. The more often I start, the easier things get finished. Overcoming that first bit of inertia is the biggest challenge (just like getting started on a run, or the first push of getting a car moving).

Once things are moving, momentum is on your side.

The shift to on-line education can happen gradually and easily

I left the following comment on Bryan Caplan’s blog post:

You don’t need to overturn all convention.  The top schools could shift at the margin, as they have many times in the past, and suddenly the conformist thing to do is to have ?? percent of your classes be on-line, and so on.  In virtually any other context you would see the flexibility of the market here!  No major credentials need to collapse, if it turns out that cannot happen easily.

This is a phantom issue, raised by many people but not thought through deeply enough.  Markets convexify (sometimes).

It is fine to argue “on-line education is not in fact more efficient.”  It is much harder to argue “if it is efficient, conformity pressures will keep it out of the market.”  Don’t confuse the former case with the latter.

Why is U.S. higher education so dominant? And why is Harvard #1?

Shailendra Raj Mehta reports:

The key innovation was alumni control of the Board of Trustees. This is what made possible several desiderata on the Rosovsky (1991) and (Aghion, Dewatripont et al. 2007) lists in the first place. This is what simultaneously allowed autonomy, continuity of purpose, large  endowments and the ability to weather turbulence. The role of alumni trustees has not been fully examined so far. Now, to be sure, Rosovsky does talk about the role of independent trustees. Certainly it is true that in one sense the trustees of US schools are often truly independent in that they provide a buffer against interference from the political and other domains. Further, they are usually able to take a view of the institution independent of the interests of the faculty. But, in fact, the trustees are not independent or uninterested observers at all. This is on account of the fact that the Board of Trustees, at least in the top US schools, consists primarily of alumni, the group which has the highest permanent stake in the reputation of the university.

…Therefore, whichever measure of school quality that we use – rank, school selectivity or endowment, we find that same result – the greater the degree of alumni control, the higher the quality of the school.

…so why is Harvard #1? This question, then becomes easy to answer. Except for a few brief years in its early days and a decade in the middle, for almost its entire existence, a period of nearly 400 years, Harvard has been controlled by its alumni.

Bryan Caplan’s signaling model and on-line education

The very useful model is here, and there is further commentary from Bryan here.  My question is this: does the model imply that on-line education should succeed, or not?

Let’s say that education signals conscientiousness.  A purely on-line class, with no ogre standing over your shoulder to discipline you, should be blown off by those who are not conscientiousness.  The on-line class would seem to offer a better signal and a cleaner separation of types.

Alternatively, let’s say education signals IQ or some other notion of “smarts.”  On-line education would seem to offer less opportunity to get through by buttering up the teacher, spouting mumbo-jumbo in basket-weaving classes, and so on.  For better or worse, a lot of on-line education seems to be based on relatively objective tests.  Then on-line education would seem to offer a better signal of smarts.

One possible application of Bryan’s model might be this.  Income inequality is rising, so there is greater care to get the signal, selection, and screening right for top jobs.  Relatively high levels of education should be all the more discriminatory, and that may mean more on-line education.  In fact, in normative terms that might well be a problem with on-line education, namely its inegalitarian nature with regard to curiosity and effort and smarts.

Oddly, the signaling model could be true, but through an invisible hand mechanism — schools competing to separate quality in the most effective ways — you can end up with a state of affairs where upfront signaling costs are fairly low.  Imagine a chess school, needing to sort talent, and unable to teach its students very much, but setting up a quite cheap on-line tournament and declaring some winners.  Aren’t the Khan Academy users some really talented people?

Alternatively, through an invisible hand mechanism, if the learning model is correct, you could end up with an equilibrium in which upfront signaling costs appear to be relatively high, namely that you impose “taxes” to make sure people end up learning what they need to know.  Think Paris Island or KIPP schools.

It is important not to confuse “seeing high upfront signaling costs” with “the signaling model of education is essentially correct.”  They sound like they should go together, but quite possibly they don’t.

Will Fairfax follow through with The Great Experiment?

Fairfax County schools could become the first in the Washington region to create a virtual public high school that would allow students to take all their classes from a computer at home.

No sports teams. No pep rallies. No lockers, no hall passes. Instead, assignments delivered on-screen and after-school clubs that meet online.

It’s a reimagination of the American high school experience. And it’s a nod to the power of the school choice movement, which has given rise to the widespread expectation that parents should have a menu of options to customize their children’s education.

Several School Board members, who will hear a formal proposal for the online school at a meeting Monday, said they are excited by the prospect.
