Zotero
Zotero is a free program for citations management and bibliography generation designed to be competitive with Endnote and similar products. I've been using it for a couple of weeks. Zotero lives as a Firefox extension and it's best feature is the ease with which you can import citations from the web. If you are looking at a paper on JSTOR, for example, you can "one-click import" the citation. One-click import is also available from Amazon, Cite-Seer, ABI-Inform, the Library of Congress, many university library catalogs, Medline, Google books and many others.
Thus it's very easy to generate a citations list in Zotero by visiting a handful of large databases – this is especially easy for books and not too hard for recent articles but it's more difficult to find older articles in online databases. Zotero's interface is somewhat clunky so entering citations by hand is not as convenient as I would like. In addition to grabbing the citation, Zotero can grab entire PDFs so you can keep articles and citations in one database. Exporting of the citations in a variety of bibliographic format is clean and well done.
Zotero is only available as a Firefox extension (the developers take a perverse pride in this fact). The developers are at GMU, although I don't know the team at all. Zotero will import citations from another citations management program so switching is low cost. Worth checking out.
My talk on economics for university administrators
Thank you all for the advice; in my talk I promoted the following ideas:
1. Many mid-level schools do not yet apply rigorous quantitative analysis in reviewing their fundraising techniques; this should change.
2. Norms will shift toward a greater inequality of rewards for lower-level staff. Yet any single administrator who tries to bulldoze through a business-like, highly-incentivized solution does so at his or her peril. The shift of norms will take a long time.
3. Community colleges are in many cases turning out to be stronger competitors than are for-profits.
4. The higher education bubble has burst. The expiration of stimulus funds in 2011 will be a crushing event for many public sector universities.
5. Faculty governance is essential for tenure and curriculum decisions. But faculty governance for setting university priorities is a big mistake.
6. The value of face-to-face classroom time (discussed in Create Your Own Economy, by the way) will prove robust. But the very best teachers of the future will take on an increasing role as editors, collage creators, and DJs. A brilliant scientist who doesn't understand YouTube will be crippled as a teacher. Adjuncts may lead the wave of innovation here.
7. The way to be fiscally responsible is to refuse luxury projects in good times. If bad times have come it is already too late.
8. Current administrators are using stimulus funds to buy off the old interest groups, under the view that these are temporary bad times. Relative to what will come, these are "good times," and much of that surplus ought to be put in reserve funds. That is not happening.
9. Many mid-level schools underinvest in making incremental improvements to their strong, core departments, because nobody gets much credit for that.
10. Being a good university administrator requires the right mix of idealism and cynicism and that is hard to come by.
What should university presidents and provosts know about economics that they don’t?
I'm giving a talk to such a group tomorrow and I am curious to hear what you think I should be telling them. This isn't a talk about public policy per se, it's a talk about the economics of universities.
In addition to what I say, I will refer them to the answers you all give.
Markets in everything
http://www.corrupted-files.com/
They advertise that it will take days for your professor to notice that the submitted paper file is corrupted. He then asks you for an uncorrupted copy, but in the meantime you have purchased a copy of the term paper you need.
I thank Tucker Hughes for the pointer.
Estimating Economic Growth
The answer is 238.64%. A good way of approximating is to use the rule of 70. If x is the growth rate then the doubling time is approximately 70/x. Thus, with a growth rate of 5% we expect a doubling (100% increase) in 14 years and a quadrupling in 28 years so a bit more than a tripling in 25 years (200% increase) is a good guess.
Auctions and Politicians
David Warsh has an excellent column on economists, auctions and the politicians who oppose them:
…the US Department of Transportation earlier this month canceled plans to auction landing slots for New York’s three busiest airports. The Bush administration had sought the measure, hoping to cut delays at the chronically congested airports (and, of course, raise some much-needed cash). The airline industry lined up against the proposal, so did Democratic congressmen. Incumbent airlines will continue to profit; frequent travelers will continue to suffer delays.
Similarly, the banking lobby, among the nation’s strongest interest groups, has so far successfully opposed Treasury Department attempts to put up for bid banks’ questionable (now “legacy”) assets. The reason is simple: when the asking price is, say, 90 cents on the dollar and the bid is closer to 40 cents, no manager will willingly take part in an auction that seems certain to lower book values.
[Similarly]…President Obama campaigned on a promise to auction the [carbon] permits. But a coalition of Midwestern and Southern Democrats teamed up to alter the bill, and when its language was released last week it turned out that fully 80 percent of the permits would be given away at first to electricity utilities and their big industrial customers…
Ask Marilyn: IQ vs. the economists
Marilyn vos Savant has (supposedly, read the link) the world's highest recorded IQ at 228. She is now fielding questions on economics. Here is one example:
Question: Why has the income disparity
grown so much in developed countries? – Matthew Cencich, Victoria,
British Columbia, Canada
Answer: I think the disparity is
a normal result of overall economic growth. The bottom incomes (zero)
can’t go lower, but the top incomes can go up and up. And so they do,
of course.
Here is another:
Question: Do you think that government
actively encouraging people to borrow money (and spend it) is the right
way to resolve the recession? – Caroline Kelly, Hendon, London
Answer:
No. I think that more consumer activity could be modestly helpful to
the economy in the short term. And in better times, it would even
masquerade as growth. But in the current climate, increasing the family
debt would cause added personal financial problems. So I doubt that
it’s useful for government to advocate shopping as a form of national
service unless elected officials are perhaps a tad more interested in
shifting a little of the burden away from themselves than they are in a
lasting solution.
She also explains the financial crisis. ("First, an economy based on growth is bound to falter now and then. A
whole sector could collapse. It’s a house of cards. Eventually, it must
morph into a system that functions on stability, or it will fail –
meaning a fall large enough to cause an unstoppable breakdown and
widespread hardship.")
Question: on these problems, does she do better or worse than leading economists?
Addendum: Here is Marilyn on YouTube. Oddly (look just past the 4:00 mark), she can't define IQ properly.
How to learn about everything?
Eric Drexler offers some tips:
- Read and skim journals and textbooks that (at the moment) you only half understand. . Include Science and Nature.
- Seldom stop to study a single subject with a student’s intensity, as if you had to pass a test on it.
- Don’t drop a subject because you know you’d fail a test – instead,
read other half-understandable journals and textbooks to accumulate
vocabulary, perspective, and context. - Notice that concepts make more sense when you revisit a topic, and note which topics provide keys to many others.
- Continue until almost everything you encounter in Science and Nature makes sense as a contribution to a field you know something about.
The three-word version of that is "Get context first."
Why are more colleges rewarding professorial research?
Dahlia Remler and Elda Pema are studying this question (do you know of an ungated copy?) but they don't yet have clear answers:
Higher education institutions and disciplines that traditionally did
little research now reward faculty largely based on research, both
funded and unfunded. Some worry that faculty devoting more time to
research harms teaching and thus harms students’ human capital
accumulation. The economics literature has largely ignored the reasons
for and desirability of this trend. We summarize, review, and extend
existing economic theories of higher education to explain why
incentives for unfunded research have increased. One theory is that
researchers more effectively teach higher order skills and therefore
increase student human capital more than non-researchers. In contrast,
according to signaling theory, education is not intrinsically
productive but only a signal that separates high- and low-ability
workers. We extend this theory by hypothesizing that researchers make
higher education more costly for low-ability students than do
non-research faculty, achieving the separation more efficiently. We
describe other theories, including research quality as a proxy for
hard-to-measure teaching quality and barriers to entry. Virtually no
evidence exists to test these theories or establish their relative
magnitudes. Research is needed, particularly to address what employers
seek from higher education graduates and to assess the validity of
current measures of teaching quality.
Here is an excellent summary of the piece, with discussion.
Can MR readers set them straight? One hypothesis is that donors prefer to affiliate with research rather than with higher teaching loads and, until the financial crisis, donors have been rising in importance for many universities.
You might also claim that faculty prefer to do research, but why are faculty getting their way more than before? (And why don't faculty just take the lower teaching load without the research requirement, if they are in charge of this evolution?) Or are you wishing to claim that research ability is a good proxy (the best available proxy?) for teaching ability? I doubt that.
My hypothesis draws on the tipping point idea. Due to coalitional politics, it's hard to keep a happy medium, so the most valuable members of the department, whether defined in terms of teaching or research, push for higher research standards than they might otherwise privately favor, if they could have their way. (This happens in both "research-teaching" departments and research departments.) They fear that turning the keys over to "the barbarians" won't much improve teaching either. Research prowess is one of the most efficient bases for organizing competing coalitions. Didn't Dr. Seuss write a novel about this?
Ideally there should be a better way to keep down the losing coalition but it
is hard to find and implement in an incentive-compatible fashion.
One implication is that when growth is high, relatively tough research standards are needed to keep down the losing coalition. When personnel is stagnant or shrinking, the emphasis on research may be less necessary because there is less chance of a shift in power.
Gambling on the Future
A conversation with the ten year-old.
"For the third time. Do your homework."
"I HATE homework. Why should I do it!"
"You need to do your homework so you can get into college and get a good job."
"Oh, Dad," (exasperated), "by the time I'm ready to go to college I'll be able to download the answers directly into my brain in twenty seconds!"
Now here is Gary Becker on fat ten-year olds.
…the negative health consequences of being overweight and even obese will generally be significantly lower for children than for adults. The reason is that aside from very extreme obesity, the really harmful effects to overweight children will not usually kick in for another 25 or more years when they are in their forties or older. However, one can reasonably expect sizable progress during the coming decades in the development of drugs, such as lipitor, that will reduce the health consequences of high cholesterol and excess weight for heart conditions, diabetes, and some cancers. From that perspective, perhaps even ignorant and impulsive children are not acting so stupidly by indulging themselves in their eating since the future will likely see the development of drugs that will alleviate many serious medical conditions.
So who is most (ir)rational, my ten-year old, the fat-ten year old or the great Gary Becker?
Toward a theory of “Assorted links”
Brad DeLong and Matt Yglesias, trendsetters of the blogosphere if there were any, are assembling "assorted links" once a day or so. As do I and Yves Smith, not to mention the Herculean efforts of Mark Thoma.
Does anyone click on these things or do you simply wish to feel you have experienced a more comprehensive menu of what you have refused to learn?
A second-order question is whether or not I should care about the answer to the first query.
TED Talks: Search, Translate, Subtitle
TED has developed a cool new technology that makes it possible to search, caption and translate TED talks. Each talk will now come with an transcript. What's cool is that you can click on any phrase in the transcript and you will jump to that point in the video. If you go to my talk, for example, and click on "open interactive transcript" you can see this in action. What this means is that videos will now be Google searchable.
In addition, by linking a translation to the English transcript it's possible to have talks searchable in multiple languages. Thus, TED is now seeking volunteer translators to convert TED talks into some 40 other languages. Here, for example, is Bonnie Bassler's great talk on quorum sensing in bacteria (how bacteria talk to one another) which is translated into Swedish and Spanish. My talk is still in English only but if anyone translates it they will get a shout out from me! With a click, translations and transcripts can be shown as subtitles so not only will TED talks be available in other languages they will also be available to the hearing impaired.
Stuff they don’t teach in graduate school
Chris Blattman has a problem to do with his research that they just don't teach about in graduate school. Which type of anti-malarial drugs should he provide for his research assistants?
be really fantastic if none of them fell deathly ill because of, well, my
research papers.
Here's the question. We have at least two perfectly
common anti-malarial options–doxycycline and mefloquine–each of which cost a
few cents each. They've been around a while, so we know what to expect. Doxy:
sun sensitivity in the occasional case, and no milk in your coffee that morning
(which is a tragedy). Mefloquine: crazy dreams among a few (including
me).
Along comes a fancy-pants new drug, Malarone. It costs $6 a pill,
with insurance, and has to be taken every day. Why would I pay 120 times more
than the generic? Is it 10 times as effective? 1.2 times? Just as effective? As
far as I can tell, there aren't studies on the matter.
Markets in everything
It's funny but to me this story is more surprising than the usual fare of prediction markets on whether bronzed bones of your ancestors will be transcribed into binary code for your Kindle, or simultaneously used as collateral for CDS swaps and bundled with adultery insurance:
Reached on the phone, Richard A. Hanson isn't quite sure he's ready
to give an interview about this week's sale of Waldorf College. The
college's president has talked quite a bit locally, trying to assure
students, professors and the residents of Forest City, Iowa, that
selling the liberal arts institution to a for-profit, online university
is the best (in fact, only) option.
What persuaded Hanson to
talk about what's happening at Waldorf is the question of whether he
thinks other colleges will soon be facing the same choice. "You are
going to be seeing a lot more of this from colleges like us," he said.
They're actually selling the college. Hurrah.
How our macro book differs
Alex already has suggested some points related to economic growth; I'll add to that:
1. We make macroeconomics as intuitive as microeconomics. Our macro is based on the idea of incentives, consistently applied.
2. We cover the current financial crisis.
3. We show a simple — yes truly simple — way of teaching the Solow Growth model. I call it Really Simple Solow. But if that's not simple enough for you, you can skip it and just call it Long-Run Aggregate Supply.
4. We offer equal and balanced coverage of neo Keynesian and real business cycle models. Most other texts emphasize one or the other.
5. We offer an intuitive way of teaching real business cycle theory. No intertemporal optimization representative agent models. Can you explain to your grandmother why swine flu has been bad for the Mexican economy? If so, you also think that real business cycle theory can be taught simply and intuitively.
6. Our version of the AD-AS model actually makes sense. We don't mash together real and nominal interest rates into the same diagram, we don't treat the Taylor rule as an assumption for deriving an AD curve, and we do the analysis consistently in terms of dynamic rates of change. (On the latter point for instance it is the rate of inflation which influences economic behavior, not the absolute level of prices per se, yet so often "p" rather than "pdot" goes on the vertical axis.)
The AD-AS analysis covers both neo Keynesian and RBC models and can be done with three simple curves in one simple graph. There is only one (consistent) model which needs to be taught for presenting the major macro ideas.
Alex and I vowed we would not stop working on this book until macro ceased to be the "ugly sister" of the micro/macro pair. Modern Principles: Macroeconomics is the result of that Auseinandersetzung.
We are heartened by the response to our previous posts on the book. Again, please do contact us if you are interested in a review copy for teaching purposes. Here is the book's home page.
