(p. A2) An economist known for pioneering work on slanted coverage in the news media won the John Bates Clark Medal, one of the profession’s most prestigious honors.

Matthew Gentzkow, a professor at the University of Chicago’s Booth School of Business, on Thursday was awarded the Clark medal by the American Economic Association, which every year honors the nation’s most promising economist under age 40.
. . .
A big theme in Mr. Gentzkow’s work is finding innovative ways to tackle questions that expand economists’ tool kits.
. . . , in 2008, he and Mr. Shapiro examined the fact that different parts of the U.S. got access to television at different times to gauge TV’s effects on high-school students in the 1960s.
The economists found that children who lived in cities that gave them more exposure to TV in early childhood performed better on tests than those with less exposure. The work also suggested TV helped American children in non-English-speaking households do better in school.

Aloysius Siow’s Obituary for Gary Becker

My friend Aloysius Siow and I were graduate students at the University of Chicago in the mid to late 1970s, where we took courses from Gary Becker, and attended his workshop. In the past, I have posted several entries on Becker on this blog that appear under the Category “Becker, Gary.” I expect to write some thoughts on his passing, but am not ready to do so yet. Aloysius drafted an obituary without delay, and kindly said it was OK for me to post it as an entry on this blog.

Obituary: Gary Becker
The Father of Economics Imperialism

By Aloysius Siow, Professor of Economics
University of Toronto
May 4, 2014

Gary Becker, an American economist, died on May 3 at the age of 83.
His major contribution was the systematic application of economics to the analysis of social issues. Before his work, economists primarily studied how markets and market economies worked. He used economics to study discrimination, criminal behavior, human capital, marriage, fertility and other social issues.
He won the Nobel Prize in economics in 1992. He also won the John Bates Clark medal, awarded to the best American economist under 40, in 1967; and the Presidential Medal of Freedom, the highest honor award by the US president to a civilian, in 2007.
Becker’s father, Louis William Becker, migrated from Montreal to the United States at age sixteen and moved several times before settling down in Pottsville, Pennsylvania. Becker’s mother was Anna Siskind. He was born in Pottsville in 1930. At age five, Gary and his family moved to Brooklyn. He studied in Princeton University as an undergraduate. He did his PhD at the University of Chicago where he met Milton Friedman who would have an enormous influence on his intellectual development. After he obtained his PhD, Becker spent a few years as an assistant professor at the University of Chicago and then moved to Columbia University.
His path breaking 1955 dissertation was on the economics of discrimination. It was the first systematic study of a non-traditional economic topic using economics. In it, he argued that the difference in wages between a majority and a minority group can be used to measure the extent of discrimination in the labor market. When one points out today that it is unfair that women earn 80 percent of what men make, they are channeling Becker. His thesis analyzed how the South African system of apartheid benefited Whites at the expense of Blacks in South Africa. This analysis predated the Anti-apartheid Boycott Movement of the West which started in 1959.
The methodology and concern of his thesis previewed his research career. At the time of the publication of his thesis in 1957, economics was a conservative discipline, restricting itself to the study of the behavior of markets and market economies. Becker set for himself the task of systematically applying the tools of economics to the study of social issues. At the beginning, his work was generally ignored if not actually denigrated within the profession. Economists were supposed to study more important concerns.
After studying discrimination, he provided a modern economic theory of criminal behavior. Together with his study on discrimination, this work inspired the development of the law and economics movement.
At Columbia University, he began a systematic study of human capital, the study of the allocation of time and other topics in labor economics. Together with his colleague Jacob Mincer, they wrote many of the important papers in labor economics and also produced many successful graduate students. For example, their graduate student, Michael Grossman, wrote his thesis on health economics where he applied economics to the study of individual maintenance of health. Today, health economics is a major field of study and a central pillar of health policy. Due to the topics they worked on, they also attracted and successfully supervised many female PhD students. Claudia Goldin of Harvard University is perhaps his most illustrious female PhD student.
In 1970, Becker returned to the University of Chicago where he remained as a professor until his death. He continue to apply his economics to the study of the family, including the behavior of marriage markets, allocation of resources within the family and fertility behavior. The discussion of how economics can affect fertility anticipated government policies which seek to increase their native fertility rates. For example, Singapore has over 30 programs which seeks to increase her fertility rate.
Today, Becker’s approach is known as the rational choice approach in the social sciences. As the economics profession grew to appreciate his contributions, other social sciences have mixed feelings about his influence. On the one hand, they appreciate how he led economists to study different social issues. On the other hand, other social scientists often feel threatened by the invasion of economists.
Economists systematically use mathematical methods, statistical analysis and often large data sets. They prioritize cost benefit calculus over other factors which may also affect individual behavior. They had little patience with qualitative studies. Thus some social scientists felt that their contributions were unfairly ignored and so resisted the application of economics to their fields. For example, the Critical Legal Studies movement was developed in the 1970s in part in reaction to the success of the law and economics movement in law schools. In political science, rational choice theory is now a core field of study. Yet there are many political scientists who reject this approach.
Interestingly, motivated by the work of psychologists, economists have also begun to reject the purely rational calculus model of Becker as too narrow. Rather, these behavioral economics researchers argue that individuals have bounded rationality and are subject to systematic biases in their behavior. For example, Robert Shiller, a Nobel economist, has argued that bubbles occur in asset markets due to psychological biases. Thus the success of Becker has led to qualifications which is a hallmark of progress in science.
Contrary to many successful economists, Becker did not spend much time consulting for either the government or business. He was a conservative but unlike his mentor Milton Friedman, his direct influence on policy was minimal. Rather, the various economic fields which he instigated have had and continue to have significant influence on public policy. For example, every politician who wants to spend more resources on public education says that they are investing in the human capital of their society. Today, economists systematically contribute to policy discussions on maternity leaves, subsidies for child care and other social issues.
On a personal note, I was a graduate student at the University of Chicago in the late seventies where I met Gary Becker. I was interested in social issues. But because he was so intimidating as a scholar, I did not write my thesis under him nor was it on those concerns. Ten years after I obtained my PhD, and after I had moved to the University of Toronto, I wrote my first paper on the economics of the family motivated by a discussion in evolutionary psychology. Our interest on the economics of the family overlapped and we subsequently have had many professional interactions. I also began to realize that he did not know everything and that it is fine to work on topics which he had worked on.
Later in his life, he would sometimes introduce me as a former PhD student. At first I would correct him. But later I did not because perhaps he was right.

Strategic Conversations: Vital to Creative Adaptation or Reinforcers of Lazy Consensus?

MomentsOfImpactBK2014-04-24.jpg

Source of book image: online version of the WSJ review quoted and cited below.

(p. A15) “Moments of Impact” is at its best on the importance of promoting different perspectives. Businesses need to look at the world through as many disciplinary lenses as possible if they are to cope with the fast-changing threats that confront them. But day-to-day corporate life is all about fences and silos. Strategic conversations give companies a chance to examine their business models from the outside–and, as the authors put it, to “imagine operating within several different yet plausible environments.”
. . .
Mr. Ertel and Ms. Solomon argue that companies increasingly face a choice between what Joseph Schumpeter called creative destruction and what they call creative adaptation–and that strategic conversations are vital to creative adaptation. Perhaps so. But strategic conversations can also reinforce lazy consensus, as people try to justify their jobs and protect their turf. Many bold decisions are driven by the opposite of “conversations”–by senior managers deciding to lop-off functions or take the company in a radically new direction.

Gary Becker’s Grandson Ponders Opportunity Cost of College

HarboeLouisYoungTechEntrepreneur2014-03-30.jpg

“Louis Harboe with his parents, Frederik Harboe and Catherine Becker. Louis, now 18, got his first freelance tech job at age 12. Last year, he attended the Apple Worldwide Developers Conference in San Francisco.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. 1) Ryan was headed to South by Southwest Interactive, the technology conference in Austin. There, he planned to talk up an app that he and a friend had built. Called Finish, it aimed to help people stop procrastinating, and was just off its high in the No. 1 spot in the productivity category in the Apple App store.
. . .
Ryan is now 17, a senior at Boulder High. He is among the many entrepreneurially minded, technologically skilled teenagers who are striving to do serious business. Their work is enabled by low-cost or free tools to make apps or to design games, and they are encouraged by tech companies and grown-ups in the field who urge them, sometimes with financial support, to accelerate their transition into “the real world.” This surge in youthful innovation and entrepreneurship looks “unprecedented,” said Gary Becker, a University of Chicago economist and a Nobel laureate.
Dr. Becker is assessing this subject from a particularly intimate vantage point. His grandson, Louis Harboe, 18, is a friend of (p. 6) Ryan’s, a technological teenager who makes Ryan look like a late bloomer. Louis, pronounced Louie, got his first freelance gig at the age of 12, designing the interface for an iPhone game. At 16, Louis, who lives with his parents in Chicago, took a summer design internship at Square, an online and mobile payment company in San Francisco, earning $1,000 a week plus a $1,000 housing stipend.
Ryan and Louis, who met online in the informal network of young developers, are hanging out this weekend in Austin at South by Southwest. They are also waiting to hear from the colleges to which they applied last fall — part of the parallel universe they also live in, the traditional one with grades and SATs and teenage responsibilities. But unlike their peers for whom college is the singular focus, they have pondered whether to go at all. It’s a good kind of problem, the kind faced by great high-school athletes or child actors who can try going pro, along with all the risk that entails.
Dr. Becker, who studies microeconomics and education, has been telling his grandson: “Go to college. Go to college.” College, he says, is the clear step to economic success. “The evidence is overwhelming.”
But the “do it now” idea, evangelized on a digital pulpit, can feel more immediate than academic empiricism. “College is not a prerequisite,” said Jess Teutonico, who runs TEDxTeen, a version of the TED talks and conferences for youth, where Ryan spoke a few weeks ago. “These kids are motivated to take over the world,” she said. “They need it fast. They need it now.”

Decline in Hours Worked Shows Weakness in Labor Market

(p. A15) Most commentators viewed the February [2014] jobs report released on March 7 as good news, indicating that the labor market is on a favorable growth path. A more careful reading shows that employment actually fell–as it has in four out of the past six months and in more than one-third of the months during the past two years.
Although it is often overlooked, a key statistic for understanding the labor market is the length of the average workweek. Small changes in the average workweek imply large changes in total hours worked. The average workweek in the U.S. has fallen to 34.2 hours in February from 34.5 hours in September 2013, according to the Bureau of Labor Statistics. That decline, coupled with mediocre job creation, implies that the total hours of employment have decreased over the period.
. . .
. . . , although the U.S. economy added about 900,000 jobs since September, the shortened workweek is equivalent to losing about one million jobs during this same period. The difference between the loss of the equivalent of one million jobs and the gain of 900,000 new jobs yields a net effect of the equivalent of 100,000 lost jobs.

Paul Ryan Warns that the Safety Net Can Be a Hammock

Ryan made similar comments in his January 25th official Republican response to the State of the Union speech:

We are at a moment, where if government’s growth is left unchecked and unchallenged, America’s best century will be considered our past century. This is a future in which we will transform our social safety net into a hammock, which lulls able-bodied people into lives of complacency and dependency.

Depending on bureaucracy to foster innovation, competitiveness, and wise consumer choices has never worked — and it won’t work now.

Disabled Workers Are More Likely to Be Free Agent Entrepreneurs

HartfordKevinEntrepreneurWhoStutters2014-03-10.jpg “Kevin Hartford, right, and a colleague at his factory. He started his business after employers failed to hire him.” Source of caption and photo: online version of the NYT article quoted and cited below.

HR departments have incentives to avoid hiring risky employees. But a determined high-risk employee can hire themselves by becoming a free agent entrepreneur. If we want to truly help the disabled, we should remove obstacles to entrepreneurship, such as burdensome regulations and high taxation.

(p. B4) Mr. Hartford, the father of two sons, thrived as a business consultant in his 20s and 30s. He was used to flying first class, staying at swank hotels and advising CEOs. Then the consulting firm unraveled in the mid-1990s. When he began looking for a new job, a stuttering problem–something he had always considered manageable–put off potential employers.

“I applied for job after job after job,” says Mr. Hartford, now 58. “I was one of two finalists; I was one of three finalists. But I never got the job.”
In the end, Mr. Hartford concluded that his only shot at a satisfying job was to create a company. He is now president and co-owner of Alle-Kiski Industries, which makes parts, such as exhaust pipes for train locomotives and prototype truck wheels, for larger manufacturers, including Alcoa Inc. and General Electric Co.
Like many before him, Mr. Hartford discovered that one option for people who don’t fit into large organizations is to start a small one. That is particularly true for people with disabilities. About 11% of disabled workers are self-employed, compared with 6.5% of those with no disabilities, according to Labor Department data.
. . .
The business has grown to 38 employees from a dozen when Messrs. Hartford and Newell started in 2005. They own more than $2 million of equipment used to drill, groove and otherwise shape metal, arrayed in a 27,000-square-foot factory with an American flag hanging from one of the beams. Last year’s sales of $6 million were the highest yet, Mr. Hartford says, and the company is building a 4,000-square-foot addition to house more equipment.

Small Business Will Fire Workers When Minimum Wage Is Raised

(p. B4) . . . , Charlene Conway is watching her numbers. For 22 years, Ms. Conway and her husband have run Carousel Family Fun Centers in Fairhaven and Whitman, Mass. The business has annual revenue of less than $500,000 and depends exclusively on part-time minimum-wage earners, mostly teenagers, to handle tasks like running the snack bar and maintaining the games.
This year, Massachusetts is considering raising its minimum to $9 an hour, from $8. Should that happen, Ms. Conway said, she will probably need to reduce her staff of 20. Her employees currently make an average of $9 an hour, with managers earning from $10 to $15. Like Ms. Riley, Ms. Conway said that an increase in the minimum would force her to raise pay across the board.
And she, too, is reluctant to raise prices again. In 2011 and 2012, she increased her admission fees by a dollar — they generally run from $5 to $10 now, based on age and time of day. Another increase, she said, would just make things worse: “We will price ourselves out of business.”
In the past, when Massachusetts increased the state’s minimum, Ms. Conway responded by increasing the minimum age of her workers to 16 from 14. “I’m not going to pay a 14-year-old $9 an hour with no experience, maturity or work ethic,” she said. More recently, she has been hiring 18-year-olds with college experience. “What this does,” she said, “is eliminate the opportunity for young people to get started in the work force.”
Should minimum wage reach $10 an hour, Ms. Conway said she would reduce her staff to 10 employees and double up on work tasks. “This is a slippery slope that could absolutely cause me to shut down and force me into bankruptcy,” she said.

The Young, with Managerial Experience, Are Most Likely to Become Entrepreneurs

(p. A13) In a current study analyzing the most recent Global Entrepreneurship Monitor (GEM) survey, my colleagues James Liang, Jackie Wang and I found that there is a strong correlation between youth and entrepreneurship. The GEM survey is an annual assessment of the “entrepreneurial activity, aspirations and attitudes” of thousands of individuals across 65 countries.
In our study of GEM data, which will be issued early next year, we found that young societies tend to generate more new businesses than older societies. Young people are more energetic and have many innovative ideas. But starting a successful business requires more than ideas. Business acumen is essential to the entrepreneur. Previous positions of responsibility in companies provide the skills needed to successfully start businesses, and young workers often do not hold those positions in aging societies, where managerial slots are clogged with older workers.
In earlier work (published in the Journal of Labor Economics, 2005), I found that Stanford MBAs who became entrepreneurs typically worked for others for five to 10 years before starting their own businesses. The GEM data reveal that in the U.S. the entrepreneurship rate peaks for individuals in their late 20s and stays high throughout the 30s. Those in their early 20s have new business ownership rates that are only two-thirds of peak rates. Those in their 50s start businesses at about half the rate of 30-year-olds.
Silicon Valley provides a case in point. Especially during the dot-com era, the Valley was filled with young people who had senior positions in startups. Some of the firms succeeded, but even those that failed provided their managers with valuable business lessons.
My co-author on the GEM study, James Liang, is an example. After spending his early years as a manager at the young and rapidly growing Oracle, he moved back to China to start Ctrip, one of the country’s largest Internet travel sites.

70 Percent of Current Jobs May Soon Be Done by Robots

Kelly may be right, but it does not imply that we will all be unemployed. What will happen is that new and better jobs, and entrepreneurial opportunities, will be created for humans.
Robots will do the boring, the dangerous, and the physically exhausting. We will do the creative and the analytic, and the social or emotional

(p. A21) Kevin Kelly set off a big debate with a piece in Wired called “Better Than Human: Why Robots Will — And Must — Take Our Jobs.” He asserted that robots will soon be performing 70 percent of existing human jobs. They will do the driving, evaluate CAT scans, even write newspaper articles. We will all have our personal bot to get coffee. There’s already an existing robot named Baxter, who is deliciously easy to train: “To train the bot you simply grab its arms and guide them in the correct motions and sequence. It’s a kind of ‘watch me do this’ routine. Baxter learns the procedure and then repeats it. Any worker is capable of this show-and-tell.”
