The Boom in College Education-Becker
The worldwide boom in college education during past several decades has been as remarkable as it was unexpected. Many economists in the United States were claiming in the 1970s that college education was overrated, at least as far as its effects on earnings. Yet starting in the late 1970s, the number of American high school graduates who went on for higher education began to grow at a reasonably fast rate. Were these college students disappointed by the effects of their education on their subsequent earnings and other aspects of their life, or did the nay-saying economists just get it wrong?
The evidence is now crystal clear that in fact college education turned out to be an excellent investment for the vast majority of these students. Despite books like "The Overeducated Americans", published in the late 1970s, that argued that the earnings gains from a college education were in serious decline, the gains from attending and graduating college actually increased rapidly after 1980. A natural interpretation of the increased enrollments in college is that expectations of improvement in their earnings, health, and other determinants of welfare attracted large numbers of Americans into higher education.
Supporting evidence for this interpretation is that the same trends in earnings and enrollments took place in the rest of the world. The earnings gap between persons with university and high school education increased in the great majority of countries, more or less regardless of their level of economic development. And as in the United States, the higher benefits from college stimulated sizable increases in the fraction of high school graduates who went on for further education. For example, in the top half of countries as measured by per capita incomes, the average percent of 30-34 year olds with a higher education increased between 1970 and 2000 from about 12 percent to over 20 percent. Lower income countries had similar increases, although poorer nations have much smaller fractions of persons with higher education.
In the great majority of countries, women increased their propensity to go to college much more rapidly than men. This sharply reduced the gender gap in college education. In fact, more women than men are getting higher education in virtually all the rich countries, and also in many middle -income countries. In the United States, a little under 60 percent of younger college graduates are now women, whereas in 1970 men were far more likely than women to start and especially to finish college.
Higher returns to college are an important immediate cause of this boom in the number of persons going to college in countries all over the globe and at different stages of economic development, but why did returns to college increase so universally? The answer must relate to general causes that were widely applicable. One factor that immediately comes to mind is the sharp expansion during the past several decades in the amount of international trade, including a rapid growth in foreign direct investment (FDI). The classical theory of international trade implies that in poorer countries with cheap low skilled labor, a growth in trade of goods and services should increase the demand for goods using relatively much of the low skilled labor, and trade should lower the demand for goods using the relatively expensive skilled labor. Increased trade has the opposite effects in rich countries. As a result, increased trade should raise the earnings of skilled workers relative to other labor in richer countries, but lower the relative earnings of skilled workers in poorer countries. Yet the gap between the earnings of skilled and less skilled workers has tended to rise in poorer countries as well.
The growth in FDI helps explain this apparent contradiction to classical trade theory, for FDI tends to raise the demand for educated and other skilled workers in recipient countries. Educated and other skilled workers become more valuable in developing countries when they import capital from the technologically advanced nations.
The newer technologies that have been developed during past three decades, such as the computer and the Internet, biotech, the mapping of the genome and other advances in medicine, and cell phones and social networking, also increased the overall demand for educated persons. Since the United States is the most important innovator in the world, and has one of the most efficient economies, it has experienced a particularly rapid widening of the college earnings premium.
Under the right circumstances, these newer technologies flow from the rich innovating countries, such as the United States and Japan, to developing and other countries. Technologies may be embodied in internationally traded goods and services, or in capital transfers, or brought back by students who study in the innovating nations. Since the international transfer of technologies is expedited by having a larger number of well -educated persons, the transfer of technologies also raises the demand for persons with higher education.
Many articles have complained that the increased benefits from higher education have contributed to widening inequality, not only in the United States, but in many other countries as well, including major developing countries like China and India. The larger education earnings premiums certainly helped widen income inequality, but these larger premiums also raised the efficiency of investments in capital by raising rates of return on human capital.
Higher returns on capital obviously raise the efficiency of an economy. The challenge to public and private policies is to increase the number of persons who manage to go to and benefit from college, for that would reduce inequality while raising the number of persons who benefit from the higher returns to a college education. How to accomplish this is too large a topic to be considered in this discussion, but improving the preparation of disadvantaged children so that they can benefit more from schooling should probably have high priority. Also important would be to increase the quality of schools available to these children by raising the degree of competition among schools.

another possibility is that many college administrations seek to increase enrollment for economies of scale, as a sign of success, or due to political pressure (when publicly funded). this is often facilitated by lowering entrance requirements for many programs, especially by community colleges. in my geographic region, it used to be common to have grade requirements to get into community college, but most programs now only require a high school dipolma, and not even that if you are above 23 years of age. anyone who has worked at the post-secondary level for long has likely encountered a desire (from administration or peers) to maintain/increase enrollments, if only to ensure the continued employment of the faculty and the flow of tuition money.
of course this is separate from the issue of whether the returns to education are worthwhile, and whether students are educated enough to good enough decisions that market pressure keeps enrollment levels on par with returns. just pointing out that there are substantial assymetrical knowledge, risk and economic issues for a student that generally do not match those of the educational institution.

I work for a fast growing high tech startup. None of our jobs have anything to do with what we studied in college. The two senior developers were a history major and communications major. One executive jokes that he majored in pot. The consultants all consult in a field that did not even exist five years ago. Browsing through my facebook friends, virtually none of my friends do anything that uses their college degree. Or look at Larry Ellison, Bill Gates, Paul Allen, Mark Zuckerberg, Steve Jobs, and Steve Wozniak. These
are the people who have driven our technological economy, yet they all dropped out of college.
The real story behind the college premium is the growth of credentialing laws. Practically all well paid professions - doctors, nurses, medical technicians, architect, lawyers, civil servants, military officers, professor, most engineers, teachers - legally require a college degree. All of these jobs are either paid for by the state, or have special state privileges ( doctors have the monopoly right of dispensing medicine, etc.) Also, the Griggs Supreme Court case played an enormous role in forcing similar credentialing upon private corporations.
I mean seriously, how many people would be paying $250,000 grand for college and law school if they could pass the bar through self-study, like Lincoln's did?
Because people go to school for the legal credential, the college has lost all incentive to actually educate. I was talking to a friend going to law school the other day, who reported, "During the summer we do internships where we get paid and we actually learn. Then we go back to school where we haven't learned anything useful since the first year." Another friend getting a masters in architecture reports the exact same thing. After a three years masters they have learned about "aura" and been indoctrinated in modernist architecture ( where they aren't allowed to use style books, because that's not "creative"). They haven't however, learned anything that's on the licensing exams, or anything else about how to actually practice architecture. That they have to learn on the job.
What we need is iron clad separation of credantialing and schooling. Only then will we be able to determine if the college premiums is really a result of returns of investment in human capital, or if it really represents the bureuacratization of our economy. My money is on the latter.

Prof Becker doesn't seem to respond to comments, but I would be interested to know if the returns to a college education increased for non-marketable majors as well, such as liberal arts, humanities, english, etc. If increasing returns to education over the past generation are due to increasing human-capital productivity--then what are these non-marketable majors doing differently today? How is shakespeare different today vs 30 or 100 years ago?

I would like to second Ryan's question: How are the returns on education doing if we kick out the engineers and leave just the liberal arts majors?
Also, other groups might disproportionately account for these returns on investment, like top students and students from top schools.
The value of a college education to the kid who is on the fence about going or not going to college seems poorly measured by considering the gross returns to all college graduates.
So what are the returns on investment for a mediocre student at a middle of the road school pursuing a liberal arts degree? Are these returns still positive?

Whether (or which) college degrees 'add value' to a person or to their earning scale is debatable, and may not be quantifiable. But, lacking a sheepskin plainly reduces earning opportunities. Analogize to any recognized distinction. Which is the better restaurant, one in the Michelin guide, or the one your best friend recommended - it's unknown, but more people may dine according to one recognized in the guidebook, even if it's not 'better.' So too, a lot of folks get degrees because they weary from being passed over for opportunities, in favor of anyone who has one more line on their resume.
As to the point about world populations with cheaper labor, consider this. Many companies, who'd tried outsourcing, ended that trial because of the perceived lack of education of those foreign workers. Then, outsourcing companies began to point out how many of their workers actually had degrees from the U.S. or Common Market universities - so, companies resumed outsourcing. The workers there, and their capability to do the work, and the cost for their work, did not change. It was the reassurance of knowing of their degrees from schools in the West that changed the employers' view of how the working relationship should be valued. So, how much were the degrees of those foreign-based workers worth?

Whew! Ryan? and Thomas?? "non-marketable" degrees?? If you read Patrick's post I think you could see that "learning to learn" is one of the values of advanced education. Did you know Carly Fiorina, who was CEO of all those engineers, scientists and techies at HP was a liberal arts major? English, history and liberal arts in general; what do you suppose those planning to become attorneys major in, in college? Those planning to be diplomats or politicians?
"The value of a college education to the kid who is on the fence about going or not going to college seems poorly measured by considering the gross returns to all college graduates."
........ wrong question in my mind. When I went to school most academics emphasized "a richer life, a better citizen, appreciation of arts and our culture" over simply looking for a return on investment in terms of one's worth to the corporate world.
Looking back I'd say they were exactly right and suggest we'd do better individually and have a much better nation were more tradesmen and others whose vocations don't "require" college to be grads or at least have a couple of years of liberal arts, political science, a class or two in law including an introduction to our Constitution.
It is indeed a shame that our stagnant wages for those of median, and below, makes the decision to spend money on college such a critical "business" decision.
And Thomas; perhaps it's even more advisable for the slow student to go to college; while he may not reap the rewards of a "front runner" consider what his lot is likely to be without college opening the doors to the "certificate" jobs Patrick mentions?

Currently, certain states of Australia are undergoing huge mining booms driven (mainly) by Chinese demand for raw materials. As a consequence of this rapid expansion, large salaries are being offered to young people who are willing to move "up north" and work on the mines. The result of this has been a significant fall in the number of students leaving school and attending university.
(eg. http://www.theaustralian.news.com.au/story/0,25197,23481617-12332,00.html)
Obviously the value of earnings now to these people outweighs the NPV of higher future earnings that they would expect if they decided instead to go to uni.

Jack -
I actually think the schooling part of college is a terrible way to "learn to learn". The tenure process for professors promotes extreme ideological narrowness. Many subjects have been dominated by quacks for centuries ( such as philosophy and literature. I personally switched out of political science because it was full of quacks who practiced modern numerology. I studied history, but even there, I have learned far more history reading books since graduation than I did going to an ivy league school.
The big lectures of most schools certainly do not promote critical thinking. The grading process promotes figuring out what the professor wants to hear. Also, success in school is very different from success in life. School promotes following the assignments, success in life is about seizing opportunities.
I also think there is no need to front load four years of liberal arts education at the beginning of life. My outlook on life has changed radically after finding a job, starting a business, etc. Even if you think liberal arts is valuable, there's no need to drag it out more for more than a year before making it on in life.
The only good thing about universities is that they bring a lot of smart and motivated people together. Most of the intellectual growth and ferment comes from dining hall, clubs, and late night bull sessions. However, there's no reason that this should cost $40,000 a year. There's a also no reason univerisites could not be replaced by intellectual societies, as we used to have in this country.
Forcing people to undergo ideollogical indoctrination by state accreditated institutions in order to practice their chosen profession is the policy of a tyranny, not a free country.

anychance the currently more women than men are in college fact furthur is somehow going to widen the gap of income between female and male workforces?

There is an issue in upper level education that I believe is being overlooked here and elsewhere that has potentially dire consequences for the Nation (yet is one of golden lies of the Free Traders movement). That is, the growing numbers of foreign students in American Universities. These students are taking up spaces that would have normally gone to American students, especially in the fields of Science, Mathematics, Engineering and Technology.
I can remember back to my days on campus when it was a big joke that there was huge mansion that was occupied by Iranain students, known to the student body at large, as the "Iranian Embassy". Large numbers passed through its doors, wearing civilianised versions of military uniforms and diplomatic suits. Where was the money coming from and why? Meanwhile, many Americans were kept out of advanced science and engineering programs that are vital to the Nations success and security.
Now the world is confronted by the specter of a Nuclearized Iran. Was this really only "Atoms for Peace"? I won't even mention the other transfer of process's and technologies that have taken place because of this knowledge transfer. Much to the detriment of the Nation, not only in the military realm, but also on the economic trade front.
National security? Don't worry about it. We live in a warm and fuzzy world where confrontation and war are things of the past.

As Professor Becker will be aware, the usual figures or returns to higher education include only earnings differentials. They are therefore substantially underestimated.
Apart from higher pay, someone with college education can also expect to live extra years, have less health problems, gain consumer satisfaction from the wider range of consumption options which they are educated to enjoy, have a better chance of marrying an educated partner and sharing in his or her gains from higher education (including probably a chance of benefiting more than otherwise from a partners' inheritance from his or her family). I would guess that college training and contacts also increase the probable lifetime total of your capital gains as well.
All this seems to apply regardless of the subject or subjects you majored in. That statistical result is no surprise when I think that the college subject which proved of most use in my own working life was philosophy. I never applied it directly, but it taught me how to learn.
The benefits also apply in all countries for which I have seen results. The world-wide surge in demand for higher education therefore makes excellent economic sense. As to where the limits to the benefits will be found, after looking for them for fourty years, they still have not shown over the horizon. I guess that is because higher education enhances people's abilities to learn about others ideas and innovations. It just might also help people to come up with new ideas of their own; but that I regard as not proven.

Patrick. good comments and I'd agree with most of them and even add that the current system with its emphasis on getting a sheepskin for career purposes is all too often taken by the student as a vaccination after which there seems little quest for more knowledge. You almost line out a prescription for school reform or an alternative.
As for cost it does seem "$40,000" is too high and unmanageable for many. But starting with $8,000 for public HS costs, and college profs earning and perhaps deserving twice what HS teachers earn, the cost per student would have to be higher, though college aged kids can more easily learn from the big lecture halls than can HS students.
While some kids seem ready to go off to a "big school" as freshmen, it seems to me that more could do well living at home or nearby and going to a local college that may well be part time and modeled on your suggestions. Recently I've seen a lot of the "front runners" that were my boy's friends in school go off to school and drop out for a bit, while others seem able to continue "getting good grades" as they did in HS.
I'm not sure about your "indoctrination" comment though. If it's about college folk becoming more liberal, (except in engineering??) I recall watching some of that happen as Soc profs asked questions as to how a farm subsidy differed from a food stamp or other "welfare" program while other classes revealed some of the inequities of our society and justice systems, and economics classes explored the difficulties of "many unorganized sellers" when the encountered the better organized "few buyers".

Jack, "except in Engineering??" It's like the rest of the University, some are and some aren't. Then there are the ones who are still trying to figure out their pocket protectors, some of them though, are the "go to" guys, especially if you're having problems with "Diffe Q". ;)
