Why is this happening? The short answer is that nobody knows for sure. One theory is that corporate cost-cutting, having thinned the ranks of workers on the factory floor and in routine office jobs, is now targeting supervisors, managers, and other highly educated people. Another theory is that technological progress, after favoring highly educated workers for a long time, is now turning on them. With rapid advances in processing power, data analysis, voice recognition, and other forms of artificial intelligence, computers can perform tasks that were previously carried out by college graduates, such as analyzing trends, translating foreign-language documents, and filing tax returns. In “The Second Machine Age” (Norton), the M.I.T. professors Erik Brynjolfsson and Andrew McAfee sketch a future where computers will start replacing doctors, lawyers, and many other highly educated professionals. “As digital labor becomes more pervasive, capable, and powerful,” they write, “companies will be increasingly unwilling to pay people wages that they’ll accept, and that will allow them to maintain the standard of living to which they’ve been accustomed.”

The new study backs up this idea, but offers a bit of good news, as well: Employees who averaged more than 10,500 steps a day or burned at least 2,100 calories were less likely to mistreat their cohabitants than those who averaged fewer steps or burned fewer calories.


If higher education serves primarily as a sorting mechanism, that might help explain another disturbing development: the tendency of many college graduates to take jobs that don’t require college degrees. Practically everyone seems to know a well-educated young person who is working in a bar or a mundane clerical job, because he or she can’t find anything better. Doubtless, the Great Recession and its aftermath are partly to blame. But something deeper, and more lasting, also seems to be happening.

Barber acknowledges that finding time to work out and get a full night’s sleep can be difficult when work pressures are mounting—and that often, job stress can directly relate to sleep quality. (Her previous research suggests that not only can a bad day at the office keep us up at night, but that poor sleep can also affect how we interpret events at work.)


And, while college graduates are still doing a lot better than nongraduates, some studies show that the earnings gap has stopped growing. The figures need careful parsing. If you lump college graduates in with people with advanced degrees, the picture looks brighter. But almost all the recent gains have gone to folks with graduate degrees. “The four-year-degree premium has remained flat over the past decade,” the Federal Reserve Bank of Cleveland reported. And one of the main reasons it went up in the first place wasn’t that college graduates were enjoying significantly higher wages. It was that the earnings of nongraduates were falling.

Previous research shows that employees who are belittled or insulted by colleagues are likely to vent their frustrations and behave angrily toward people outside of work, says study co-author Shannon Taylor, a management professor at the University of Central Florida’s College of Business.


The “message from the media, from the business community, and even from many parts of the government has been that a college degree is more important than ever in order to have a good career,” Peter Cappelli, a professor of management at Wharton, notes in his informative and refreshingly skeptical new book, “Will College Pay Off?” (PublicAffairs). “As a result, families feel even more pressure to send their kids to college. This is at a time when more families find those costs to be a serious burden.” During recent decades, tuition and other charges have risen sharply—many colleges charge more than fifty thousand dollars a year in tuition and fees. Even if you factor in the expansion of financial aid, Cappelli reports, “students in the United States pay about four times more than their peers in countries elsewhere.”

Being mistreated at work can make people take out their frustrations on loved ones at home. But a new study suggests that getting more exercise and sleep may help people better cope with those negative emotions by leaving them at work, where they belong.


Obtaining a vocational degree or certificate is one strategy that many students employ to make themselves attractive to employers, and, on the face of it, this seems sensible. If you’d like to be a radiology technician, shouldn’t you get a B.A. in radiology? If you want to run a bakery, why not apply to Kansas State and sign up for that major in Bakery Science? But narrowly focussed degrees are risky. “If you graduate in a year when gambling is up and the casinos like your casino management degree, you probably have hit it big,” Cappelli writes. “If they aren’t hiring when you graduate, you may be even worse off getting a first job with that degree anywhere else precisely because it was so tuned to that group of employers.” During the dot-com era, enrollment in computer-science and information-technology programs rose sharply. After the bursting of the stock-market bubble, many of these graduates couldn’t find work. “Employers who say that we need more engineers or IT grads are not promising to hire them when they graduate in four years,” Cappelli notes. “Pushing kids into a field like health care because someone believes there is a need there now will not guarantee that they all get jobs and, if they do, that those jobs will be as good as workers in that field have now.”

The findings also revealed that when employees felt they had a bad night’s sleep because of work issues, they were more likely to be grouchy at home. “When you’re tired, you’re either less able or less motivated to regulate yourself,” says co-author Larissa Barber, professor of psychology at Northern Illinois University.

A paper — from Matthew Gibson of Williams College and Jeffrey Shrader of the University of California at San Diego, based on data from Jawbone, the fitness- and sleep-tracker company — says that additional time sleeping can translate into thousands of dollars in wages。

Increasingly, the competition for jobs is taking place in areas of the labor market where college graduates didn’t previously tend to compete. As Beaudry, Green, and Sand put it, “having a B.A. is less about obtaining access to high paying managerial and technology jobs and more about beating out less educated workers for the Barista or clerical job.” Even many graduates in science, technology, engineering, and mathematics—the so-called STEM subjects, which receive so much official encouragement—are having a tough time getting the jobs they’d like. Cappelli reports that only about a fifth of recent graduates with STEM degrees got jobs that made use of that training. “The evidence for recent grads suggests clearly that there is no overall shortage of STEM grads,” he writes.

Physical activity seems to counterbalance poor sleep, Barber says, because it promotes healthy brain functions needed to properly regulate emotions and behavior. “This study suggests that high amounts of exercise can be at least one way to compensate for sleep troubles that lead to negative behaviors at home,” she says.

Now, the story is not so simple。 Don‘t think you can start to sleep more and you will instantly make more money。 It’s more about the subtle interplay between how people schedule their lives, how much time they have available to sleep and how that affects worker performance and, ultimately, earnings。

In the fast-growing for-profit college sector, which now accounts for more than ten per cent of all students, vocational degrees are the norm. DeVry University—which last year taught more than sixty thousand students, at more than seventy-five campuses—offers majors in everything from multimedia design and development to health-care administration. On its Web site, DeVry boasts, “In 2013, 90% of DeVry University associate and bachelor’s degree grads actively seeking employment had careers in their field within six months of graduation.” That sounds impressive—until you notice that the figure includes those graduates who had jobs in their field before graduation. (Many DeVry students are working adults who attend college part-time to further their careers.) Nor is the phrase “in their field” clearly defined. “Would you be okay rolling the dice on a degree in communications based on information like that?” Cappelli writes. He notes that research by the nonprofit National Association of Colleges and Employers found that, in the same year, just 6.5 per cent of graduates with communications degrees were offered jobs in the field. It may be unfair to single out DeVry, which is one of the more reputable for-profit education providers. But the example illustrates Cappelli’s larger point: many of the claims that are made about higher education don’t stand up to scrutiny.

The researchers even calculated the exact energy expenditure needed to protect against work-to-home emotional spillover. Burning an additional 587 calories, the equivalent of a 90-minute brisk walk or an hour-long swim for a 195-pound male, can “substantially reduce the harmful effects of workplace undermining,” they wrote.

They find that a one-hour increase in average weekly sleep in a location increases wages by 1.3 percent in the short run, which include changes of less than a year, and 5 percent in the long run。 By moving to a location where a sunset is one hour earlier, a worker will make an additional $1,570 a year。

Despite the increasing costs—and the claims about a shortage of college graduates—the number of people attending and graduating from four-year educational institutions keeps going up. In the 2000-01 academic year, American colleges awarded almost 1.3 million bachelor’s degrees. A decade later, the figure had jumped nearly forty per cent, to more than 1.7 million. About seventy per cent of all high-school graduates now go on to college, and half of all Americans between the ages of twenty-five and thirty-four have a college degree. That’s a big change. In 1980, only one in six Americans twenty-five and older were college graduates. Fifty years ago, it was fewer than one in ten. To cater to all the new students, colleges keep expanding and adding courses, many of them vocationally inclined. At Kansas State, undergraduates can major in Bakery Science and Management or Wildlife and Outdoor Enterprise Management. They can minor in Unmanned Aircraft Systems or Pet Food Science. Oklahoma State offers a degree in Fire Protection and Safety Engineering and Technology. At Utica College, you can major in Economic Crime Detection.

The researchers used activity trackers to record sleep patterns and physical activity of 118 graduate students with full-time jobs. Each participant, and one person he or she lived with, also completed surveys about sleep, exercise and feelings of mistreatment at home or work.

We all know sleep matters for job performance。 After a week of vacation, you may find your work better than ever。 It wouldn‘t surprise anyone that sleep affects attention, memory and cognition — important factors in the workplace。 But striking new research suggests the effect of additional sleep has a high monetary value。

Cappelli stresses the change in corporate hiring patterns. In the old days, Fortune 500 companies such as General Motors, Citigroup, and I.B.M. took on large numbers of college graduates and trained them for a lifetime at the company. But corporations now invest less in education and training, and, instead of promoting someone, or finding someone in the company to fill a specialized role, they tend to hire from outside. Grooming the next generation of leadership is much less of a concern. “What employers want from college graduates now is the same thing they want from applicants who have been out of school for years, and that is job skills and the ability to contribute now,” Cappelli writes. “That change is fundamental, and it is the reason that getting a good job out of college is now such a challenge.”

People who burned more calories on a daily basis—by doing the equivalent of a long walk or swim—were less likely to take out their anger about work issues on people they lived with, the researchers found in the new study, which was published in the Journal of Applied Psychology.
