Vox: DACA boosted immigrants’ education, labor force participation, productivity

It also cut teen pregnancy.

Journalist Matthew Yglesias with the website Vox covered the research of SMU government policy expert Elira Kuka. Her working paper, “Do Human Capital Decisions Respond to the Returns to Education? Evidence from DACA,” was released in February by the National Bureau of Economic Research.

Kuka, an assistant professor in the SMU Department of Economics, and her colleagues found that the Deferred Action for Childhood Arrivals program under fire by the Trump Administration has significantly changed the lives of young people who came to the United States illegally as children.

Kuka’s research focus is on understanding how government policy effects individual behavior and well-being, the extent to which it provides social insurance during times of need, and its effectiveness in alleviation of poverty and inequality.

Her current research topics include the potential benefits of the Unemployment Insurance (UI) program, the protective power of the U.S. safety net during recessions and various issues in academic achievement.

EXCERPT:

By Matthew Yglesias
Vox

The Deferred Action for Childhood Arrivals program changed the lives of young people who came to the United States illegally as children in incredible ways — boosting high school graduation rates and college enrollment, while slashing teen births by a staggering 45 percent.

That’s according to timely new research from Elira Kuka, Na’ama Shenhav, and Kevin Shih that uses the program to study a larger question that’s of interest to economists — when education becomes more available, do people go get more of it? The DACA results suggest that the answer is yes, at least when there’s a clear upside. The program itself, in other words, was a smashing success in terms of bringing people out of the shadows and letting them contribute more to American society.

Oscar Hernandez, a DACA recipient, explained to Vox’s Dara Lind how things changed.

”The discussion in my house was, ‘You don’t get noticed. Because if you do something awesome and great, you might get noticed, and if you do get noticed, they might find out that we’re here undocumented, and if they find we out we could get separated.’ It was never a discussion we had, but that was the unwritten rule for our house. You don’t do bad things, but you also don’t do good things. You stay under the radar, you work, and that’s it.”

DACA changed that. Suddenly, recipients got to experience what US citizens take for granted — that to excel is good.

Canceling DACA almost certainly won’t reduce the overall size of the unauthorized population living in the United States, but it will meaningfully reduce the educational attainment and economic productivity of the undocumented population. That’s bad for the DREAMers, but also America as a whole.

DACA eligibility led to a lot more schooling
One of DACA’s provisions was that to qualify, you had to get a high school degree if you were old enough. That’s an unusual incentive to stay in school, and using a difference-in-differences design to compare the eligible to non-eligible population over time (you can do this because you had to have arrived within a specific time and age window to qualify) they show that DACA-eligibility increased high school graduation rates by 15 percent and brought teen births down by 45 percent.

Female students exposed briefly to charismatic career women are inspired to pursue male-dominated field

Easy, inexpensive experiment briefly sent inspiring female role models into intro to econ classes and sharply increased college female interest in the male-dominated, well-paying field of economics.

A low-budget field experiment to tackle the lack of women in the male-dominated field of economics has been surprisingly effective, says the study’s author, an economist at Southern Methodist University, Dallas.

Top female college students were inspired to pursue a major in economics when exposed very briefly to charismatic, successful women in the field, according to SMU economist Danila Serra.

The results suggest that exposing young women to an inspiring female role model succeeds due to the mix of both information and pure inspiration, Serra said.

“The specific women who came and talked to the students were key to the success of the intervention,” she said. “It was a factor of how charismatic and enthusiastic they were about their careers and of how interesting their jobs looked to young women.”

Given the simplicity and low-cost of the intervention, similar experiments could be easily conducted in other male-dominated or female-dominated fields of study to enhance gender diversity.

Serra’s results showed that among female students exposed to the enthusiastic mentors there was a 12-percentage point increase in the percentage of female students enrolling in the upper-level Intermediate Microeconomics course the following year — a 100% increase, or doubling, for that demographic.

Not surprisingly, given that the intervention was targeted to female students, Serra found that the role model visits had no impact on male students.

But astonishingly it had the greatest impact on high-achieving female students.

“If we restrict the analysis to the top female students, the students with a GPA of 3.7 or higher, the impact is remarkable — it is a 26 percentage points increase,” Serra said. “So this intervention was especially impactful on the top female students who perhaps were not thinking about majoring in economics.”

The results were very surprising to Serra, an assistant professor in the SMU Department of Economics in Dedman College who teaches the upper-level class Behavioral and Experimental Economics. Serra’s research relies on laboratory and field experiments, a relatively new methodology in the field of economics. She launched and is co-leader of the Laboratory for Research in Experimental Economics at SMU.

“I didn’t think such limited exposure would have such a large impact,” Serra said. “So this is telling me that one of the reasons we see so few women in certain fields is that these fields have been male-dominated for so long. This implies that it is very difficult for a young woman to come into contact with a woman in the field who has an interesting job in the eyes of young women and is enthusiastic about her major and her work. Young men, on the other hand, have these interactions all the time because there are so many male economics majors out there.”

Co-author on the research is Catherine Porter, associate professor of economics at Heriot-Watt University, Edinburgh, Scotland, and Serra’s former Ph.D. classmate at the University of Oxford.

“The gender imbalance in economics has been in the news a lot lately, and much of the discussion has been very negative,” said Porter. “This study offers something positive: a cheap way of improving the gender balance. The results can hopefully be used by other schools in order to redress the low numbers of women that major in economics – women have a lot to offer and should consider economics as a subject that is interesting and varied for a career.”

Serra reported the findings, “Gender differences in the choice of major: The importance of female role models,” on Jan. 6 in Philadelphia at the 2018 annual meeting of the Allied Social Sciences Association. Hers is one of many findings on gender and gender differences in economics presented at a session organized by the Committee for the Status of Women in the Economics Profession.

Inspiring the individual is the best tool to recruit and retain
Serra launched the study after SMU was one of 20 U.S. universities randomly chosen by Harvard economics professor Claudia Goldin for the Undergraduate Women in Economics Challenge. The project awarded each university a $12,500 grant to develop a program freely chosen by the universities to test the effectiveness of a deliberate intervention strategy to recruit and retain female majors.

Nationally, there’s only about one woman for every three men majoring in economics. SMU has a large number of economics majors for a school of its size, with 160 a year. The gender imbalance, however, is greater at SMU than the national average, with only one woman to every four men.

Serra developed her intervention based on her own experience as a Ph.D. student at the University of Oxford several years ago.

“I started thinking about role models from my personal experience,” Serra said. “As a student, I had met many female professors in the past, but my own experience taught me that inspiration is not about meeting any female professor — it’s about meeting that one person that has a huge charisma and who is highly inspiring and speaks to you specifically.”

Serra said that’s what she experienced as a graduate researcher when she first met Professor Abigail Barr, who later became her Ph.D. advisor.

“I know for a fact that that is why I decided to do a Ph.D. in economics, because I was greatly inspired by this person, her experiences and her research,” she said. “So I thought it would be interesting to see whether the same could work for a general student population.”

Two inspiring women role models, 15 minutes, four classrooms
Serra asked two of her department’s top undergraduate female economics students to take the lead in choosing the role models.

The students, Tracy Nelson and Emily Towler, sorted through rosters of SMU economics alums and shortlisted 18 men and women that they thought were working in interesting fields – which purposely excluded stereotypical jobs in banking and finance – and then carried out scripted interviews with a subset of who agreed to be interviewed via Skype to get additional information about their career path and to assess their charisma.

The students ultimately found two alumnae, Julie Lutz and Courtney Thompson, to be the most inspiring. Lutz, a 2008 graduate, started her career in management consulting but, shortly after, decided to completely change her career path by going to work for an international NGO in Nicaragua, and then as a director of operations at a toy company based in Honduras. Lutz now works in Operations at a fast-growing candy retail company. Courtney Thompson, class of 1991, has had a stellar career in marketing, becoming the senior director of North American Marketing and Information Technology at a large international communications company, with the unique claim of being not only a female econ major at a time when that was exceedingly rare, but also African American in a white dominated field.

Serra invited each woman to speak during the Spring 2016 semester for 10 to 15 minutes to four Principals of Economics classes that she had randomly selected from a set of 10. The Principles classes are very popular, with about 700 students total from a variety of desired majors, and are typically gender balanced. The imbalance, said Serra, starts the following year with Intermediate Microeconomics, which is a requirement for upper-level economics courses and so is a good indicator of a desire to major in economics.

Serra offered each role model an honorarium for speaking, but each woman declined and indicated they were happy to be back on campus sharing with students. Serra told the speakers nothing of the purpose of the research project, but encouraged each one to explain to the class why they majored in economics and to be very engaging. She directed them to approach the students with the following question in mind: “If you had to convince a student to major in economics, what would you say?”

Thompson, Serra said, during her college days played SMU’s costumed Peruna mascot, and today retains a “bubbly, big personality, that makes her extremely engaging.” In her classroom visits, Thompson described her experience working and being extremely successful in marketing with an economics degree, while being surrounded by business majors. Lutz, being still in her 20s, was very easy for the young women in the classrooms to identify with, and her experience working in the non-profit and in developing countries may have been especially appealing to them.

Young women judge best who will inspire them
Serra believes that a key to the success of the intervention was the fact her two female economics students actively participated in the selection of the role models.

“The most important thing about the project was that I realized I needed current female students to choose the role models,” Serra said. “I’m not that young anymore, so I’m probably not the best person to recognize what is inspiring to young women. I think young female students are in the best position to tell us what is most inspiring to them.”

In November the directors and officers of the International Foundation for Research in Experimental Economics honored Serra as the inaugural recipient of the $50,000 Vernon L. Smith Ascending Scholar Prize. The Smith Prize is described by the foundation as a “budding genius” award.

For her highly cited corruption research, Serra uses lab experiments to study bribery, governance and accountability, questioning long-standing assumptions. Some of her findings are that corruption declines as perpetrators take into account social costs of their illegal activities, and as victims share information about specific bribery exchanges through online reporting. Serra’s current research agenda also includes experimental work on gender differences in preferences, behaviors and outcomes. — Margaret Allen, SMU

Daily Planet: Star Wars come to life in SMU chemist’s invention

Long ago, sort of, scenes from Star Wars triggered a child’s imagination, so that today it’s informed one of his research goals as a chemist.

Discover Canada’s science magazine show Daily Planet reported on the research of SMU organic chemist Alex Lippert, an assistant professor in the Department of Chemistry in SMU’s Dedman College of Humanities and Sciences.

Lippert’s team develops synthetic organic compounds that glow in reaction to certain conditions. He led his lab in developing a new technology that uses photoswitch molecules to craft 3-D light structures — not holograms — that are viewable from 360 degrees. An economical method for shaping light into an infinite number of volumetric objects, the technology will be useful in a variety of fields, from biomedical imaging, education and engineering, to TV, movies, video games and more.

For biomedical imaging, Lippert says the nearest-term application of the technique might be in high-volume pre-clinical animal imaging, but eventually the technique could be applied to provide low-cost internal imaging in the developing world, or less costly imaging in the developed world.

The Daily Planet segment aired Dec. 12, 2017.

Lippert’s lab includes four doctoral students and five undergraduates who assist in his research. He recently received a prestigious National Science Foundation Career Award, expected to total $611,000 over five years, to fund his research into alternative internal imaging techniques.

NSF Career Awards are given to tenure-track faculty members who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research in American colleges and universities.

Lippert joined SMU in 2012. He was previously a postdoctoral researcher at the University of California, Berkeley, and earned his Ph.D. at the University of Pennsylvania, and Bachelor of Science at the California Institute of Technology.

Cyber grad and U.S. Marine Corps vet Michael Taylor proved his mettle as an outstanding student researcher

‘Outstanding student in computer science & engineering’ graduates Dec. 16 with master’s degree and Raytheon ticket to a Ph.D.

Michael Taylor will be the first to tell you that he was not ready for college when he graduated from Plano East High School in 2006. And he’ll also tell you that nobody was more surprised than he was when SMU admitted him in 2014, a little later than the average undergrad.

But Taylor’s disciplined approach to life, honed through five years in the Marine Corps, combined with the intelligence he learned to tap, has earned him a master’s degree from SMU’s Lyle School of Engineering that will be awarded Dec. 16. And after proving his mettle as a student researcher in Lyle’s Darwin Deason Institute for Cyber Security, Taylor has been awarded the first Raytheon IIS Cyber Elite Graduate Fellowship, which will fund his Ph.D. in quantum computing at SMU and then put him to work as an employee at Raytheon.

“Michael Taylor stood out to me when I first had him in an undergraduate class,” said Mitch Thornton, research director for the Deason Institute and Cecil H. Green Chair of Engineering at SMU. “I could sense there was something special about him and that he had a lot of talent. I actively encouraged Michael to do research with me and he has excelled in everything I have asked him to work on. He is a credit to the student body of SMU’s Lyle School, and a credit to the nation.”

Taylor learned to focus on the details in the Marine Corps. He had sampled community college very briefly after high school, but it didn’t stick. He knew he didn’t have skills to trade for a decent job, so joining the Marine Corps made sense to him.

“Honestly? In retrospect, I wasn’t ready for school,” Taylor acknowledged.

After the Marines, finally ready for college
Taylor’s dad was an SMU engineering alumnus, and this was not the career path he’d envisioned for his son. But it’s funny how things work themselves out. Taylor completed Marine basic training, and took an aptitude test to determine where his skills might fit the Marine Corp mission. He did very, very well.

“My score on that test – I qualified for every enlisted job in the Marine Corps,” Taylor said. “I got to pick what job I wanted.” Working as a calibration technician sounded interesting – a job that would require him to conduct testing for proper operation of a wide range of mechanical and electronic devices and tools. But before working in calibration, he’d have to go school for a year.

“Ironic, I know,” Taylor said, smiling. “I had to sign up for an extra year, so I ended up doing a five-year tour in the Marines.”

He spent most of that time working out of Camp Pendleton in California, but was deployed to Helmand Province, Afghanistan, from March through September 2010, at the height of the surge of U.S. troops. “I wasn’t a combat guy,” Taylor said. “But even on base, sometimes, the rockets would come in the middle of the night.”

Nearing the end of his enlistment in 2012, Taylor was getting the hard sell to stay in and make the Marines a career. By now, he had decided he was ready for college, but the career planner he met with tried hard to talk him out of it, predicting that Taylor would “fail again.”

“He actually told me if I got out of the Marine Corps and went back to college, I’d end up living under a bridge,” Taylor said, shaking his head. It just made him more determined to succeed.

He started back at community college, and this experience was very different. “It seemed like it was so hard the first time,” Taylor said. “What then seemed like a monumental task, now seemed like nothing. I started thinking, I might be able to do school, now.”

And he started thinking about SMU. Taylor’s grades at Collin County Community College were good – good enough to get him into his father’s alma mater.

SMU Prof’s mentoring made all the difference
Taylor never dared to think he could live up to what his Dad had accomplished, starting with the scholarship to attend SMU that Jim Taylor ’89 had received from Texas Instruments. “He was a technician there,” Taylor recalled, “and they paid for him to come here. As a kid, if you’d told me I could do something like that, too, I’d never have believed you. For me there was Albert Einstein, and Jim Taylor.”

Michael Taylor came to the Hilltop on the GI Bill, and SMU’s Yellow Ribbon program for military veterans covered what the GI Bill didn’t. Then, the Darwin Deason Institute for Cyber Security picked up the cost of his master’s degree.

Taylor’s first semester at SMU’s Lyle School was a tough adjustment after his relatively easy path at community college, but that class with professor Thornton his second semester changed everything. “Dr. Thornton offered me a position working in the Deason Institute for Cyber Security,” Taylor said. “It’s been going great since then.”

Thornton’s influence and mentoring made all the difference for Taylor.

“If I had not met Dr. Thornton, there were times I wondered if I would have gotten my bachelor’s degree. I definitely wouldn’t be getting the master’s degree. And a Ph.D. wouldn’t have been something I ever considered.”

Compelled to dive into quantum computing and cyber security
Taylor was interested in computer hardware when he arrived at SMU, but the Deason Institute opened the door to the contributions he could make in cyber security. He received the Lyle School’s 2017 Rick A. Barrett Memorial Award for outstanding work in computer science and engineering. And as he neared the completion of his master’s degree, he was tapped for the Raytheon Cyber Elite Graduate Fellowship and is looking forward to pursuing his Ph.D. in quantum computing.

“Quantum computers solve problems that are too difficult for classical computers to solve,” Taylor said. “Certain problems in classical computation are intractable, there’s no way you can solve them in this lifetime. It’s only a matter of time before quantum computers render all encryption obsolete.”

For Fred Chang, executive director of SMU’s Deason Institute and former research director for the National Security Agency (NSA), finding talented students like Taylor to fill the gaps in the cyber security workforce is “job one.” Chang testified before a congressional subcommittee in September that we are likely facing a worldwide shortage of cyber security workers five years from now.

“Today’s students will be responsible for designing, creating, operating, maintaining and defending tomorrow’s cyber infrastructure,” Chang explained. “We need a large and capable pool of folks to staff these positions for the future.”

For Taylor, cyber security is just plain compelling.

“I just like the challenge. There’s somebody out there that’s trying to crack what you have, to break you down. You have to be smarter than them. It’s a game!” — Kim Cobb, SMU

SMU economist wins $50,000 “budding genius” prize with highly cited corruption research

Serra questioned long-standing assumptions; found corruption declines as perpetrators take into account social costs of their illegal activities, and as victims share information about specific bribery exchanges through online reporting systems.

Guilt and shame play a role in reducing bribery, according to research by economist Danila Serra, Southern Methodist University, Dallas.

As an economist who has studied bribery behavior extensively, Serra has discovered that bribery declines if potentially corrupt agents are made aware of the negative effects of corruption, and when victims can share specific information about bribe demands through online reporting systems.

An assistant professor in the SMU Department of Economics, Serra’s research methodology is unique — relying on lab experiments in which players gain and lose real money. Her work is frequently cited by other researchers studying the field of bribery.

In November the directors and officers of the International Foundation for Research in Experimental Economics honored Serra as the inaugural recipient of the $50,000 Vernon L. Smith Ascending Scholar Prize. The Smith Prize is described by the foundation as a “budding genius” award.

“Dr. Serra’s accomplishments have marked her as an ascending scholar, teacher, mentor and colleague of exceptional promise,” said a statement from the foundation.

The prize is named for Nobel Laureate Vernon L. Smith, considered the father of experimental economics. It aims to build on his legacy and inspire recipients, early on in their careers, to set the loftiest possible goals for themselves as social-science theorists, practitioners, colleagues, mentors and truth seekers, the foundation said.

Serra’s interest in understanding bribery transformed in 2005 when she became frustrated by measurement problems and the difficulty of finding good data. Her goal was to identify and understand the causes of corruption, and in particular whether non-monetary motivations, social norms and culture play any role in corruption decision-making. During her Ph.D. work at the University of Oxford, economist Abigail Barr exposed Serra to lab experiments, a relatively new methodology for the field of economics.

“I was always interested in corruption. As soon as I discovered the field of experimental economics I decided to design and implement bribery experiments,” Serra said. “I recreate the situation I want to study in a laboratory setting, employing real monetary incentives, which we provide, and with scenarios where the subjects can make corruption decisions that increase their money at the expense of other players. The play is anonymous and they get to bring home the money they earn in the experimental setting.”

Corruption isn’t purely about money
The focus of Serra’s research sharpened further when she began to question the root assumption that guilt and shame don’t play a role in bribery. She found in laboratory experiments that the intrinsic costs of guilt and shame do matter, and that corruption isn’t purely a matter of money.

She found that corruption declines when potentially corrupt agents are made aware of the negative impact of their actions, and when bottom-up anti-corruption mechanisms are in place, such as victims sharing specific information about bribe demands. Serra also found evidence of a significant relationship between corruption and culture.

“In one of my early studies, I employed a sample of international students at the University of Oxford and found among undergraduate students that the level of corruption in their home country predicts their propensity to engage in corruption in my bribery experiment,” she said.

“This is what we’d expect, they have internalized corrupt norms,” Serra said. “But the surprising result is that this wasn’t true for graduate students. We concluded that graduate students do not conform to the prevailing social norms of their home countries and, possibly, they want to distance themselves from such norms.”

Serra’s research has produced 12 papers on bribery and she has edited a book about experimental research on corruption. Her work on corruption has been cited hundreds of times by other researchers in the field. She has also investigated issues related to governance, public service provision and bottom-up accountability in developing countries. More recently, she has embarked on new research exploring gender differences in behaviors and outcomes in a variety of contexts, including students’ choices of major.

Serra launched and is co-leader of the Laboratory for Research in Experimental Economics at SMU’s Economics Department in the Dedman College of Humanities & Sciences.

The Vernon L. Smith Ascending Prize for Serra is a major professional recognition of the profound impact of her pioneering research in the area of experimental public economics and in particular on the understanding of corruption and other forms of rule breaking, said SMU economist Santanu Roy, chair of the SMU Department of Economics and University Distinguished Professor.

“She is one of the most cited economists of her generation,” Roy said. “The prize comes with a $50,000 award which, as far as I know, is the largest amount awarded as a prize for young economists. The fact that Dr. Serra was chosen to receive the inaugural prize named for the father of experimental economics tells us about the high expectations that her peers have about her future research productivity.”

Economics as an empirical discipline
The Smith Prize seeks to inspire early-career scholars to emulate Smith’s joyous zeal for scientific discovery. It may be used flexibly to advance social science in whatever manner a recipient chooses, the foundation said.

The prize is made possible through the Rasmuson Foundation and other contributors.

As a social scientist, Smith was committed to exploring theoretical foundations in economics, social science, and science generally; achievement in the form of quantifiable impacts in transforming economics into an experimental and more empirical discipline; collegiality in funding, mentoring, and collaborating with fellow scholars; and curiosity in looking beyond traditional disciplinary boundaries in search of truth.

“The International Foundation for Research in Experimental Economics heartily congratulates Dr. Serra and looks forward to following her career in the years to come,” the statement said. — Margaret Allen, SMU
