It might seem unsurprising that politically connected firms would have received more federal bailout funds after the 2008 financial crisis, but Ran Duchin鈥攁 newly minted Ph.D. at the time of the meltdown鈥攚as skeptical that politics played much of a role in finance. That is, until he dug into the data. Duchin鈥檚 finding that the connected firms indeed benefited disproportionately from the bailout made national headlines. In a subsequent study, he found that the bailed-out banks engaged in riskier behavior.

鈥淓ver since then, I鈥檝e been interested in the political economy,鈥� Duchin says. In published in The听Review of Financial Studies, Duchin and colleagues examined federal procurement contracts. 鈥淭he U.S. federal government is the largest customer in the world,鈥� says Duchin. 鈥淭hey鈥檙e purchasing everything from pens and paper all the way up to nuclear missiles.鈥� The researchers discovered that politically connected firms bid low to give the appearance of fairness, but then extract higher payments through renegotiations during the often years-long duration of the contract.

Duchin comes to the Heights from the Foster School of Business at the University of Washington, where he was the William Fowler Professor of Finance. He has taught undergrads as well as M.B.A. and Ph.D. students, and, all things being equal, he says he most relishes teaching undergrads. 鈥淎t the end of the day, those are the ones you can influence the most,鈥� he says. 鈥淓ven ten years later, I鈥檒l get emails from former undergrad students saying, 鈥楽omething I learned in your class was useful at work today鈥� or 鈥榟elped me in an interview.鈥� Hopefully, I鈥檓 helping to raise new generations of socially conscious finance experts.鈥�

What鈥檚 the difference between 4.24 and 4.26? If we鈥檙e talking stars on Yelp, that tiny decimal distance could determine whether an auto mechanic will give you speedy service, along with a free cup of coffee while you wait鈥攐r turn you away altogether.

Megan Hunter often marveled at how quickly consumers came to base their purchasing decisions on customer reviews found on Yelp and other online platforms. And indeed, scholarly research does exist on this phenomenon. But until a听, not much was known about how companies change their behavior as a result of those reviews.

What Hunter found, in the context of online reviews of auto repair shops, was that businesses either put in an extra effort or turn down risky jobs (repairs), depending on whether their average rating on a major review site is just above or just below a rounding threshold鈥攆or example, 4.25. The sites don鈥檛 actually show precise averages but rather round down a 4.24 (for example) to just 4 stars, while rounding a 4.26 up to 4 and a half stars. So if a mechanic is on the cusp of what appears to be a half-star rise or drop in rating, then he will go the extra mile to influence a customer鈥檚 review鈥攐r decide not to take on a complicated repair that could garner a mixed review.

In addition to research, Hunter relishes teaching. 鈥淚 love seeing the light bulb go off for a student, when a particular concept clicks,鈥� she says. 鈥淪tudents often make connections and ask questions about related topics that I would not have considered!鈥�

Hunter has worked as a senior research analyst for the Federal Reserve Bank of New York. A native of Southern California, she grew up surfing, and since moving to Boston has taken up paddle boarding on the Charles.听

Grace Gu

Assistant Professor

Areas of Interest:听Technology strategies, digitization and innovation, platform markets

The听听called a paper of Grace Gu鈥檚 鈥済ood and important news鈥� for civil discourse and credible information on the internet. In 鈥淚deology and Composition Shift Among an Online Crowd: Evidence from Wikipedians,鈥� Gu and colleagues found that鈥攗nlike on Facebook and Twitter鈥攖he anonymous editors who contribute to Wikipedia tend to move toward less segregated conversations and become more neutral over time, not more extreme. Whereas those other large online platforms use algorithms that expose users to content that aligns with their views, Wikipedia鈥檚 design forces contributors to grapple with facts they might otherwise prefer to ignore.

Asked how she was drawn to such a topic, Gu says simply, "I grew up in the Information Age, and I got quite interested in studying online information and digitization when I entered college." More recently, with debates over net neutrality raging, many have worried that the Internet is becoming more and more polarized. "So I decided to study the biases and slants in user-generated contents on Wikipedia in the hope that I can contribute theoretical and quantitative insights to this topic."

Gu takes the same spirit of shared conversation to her teaching. "What I love most about teaching is the process of mutual learning," she adds. "I have been inspired by my students in so many ways, both in class and during casual discussions. They bring new perspectives to the topics I teach, and I really enjoy hearing their thoughts and exploring with them about the newest ideas in the field."

鈥淚magine if you asked a patient, 鈥榃ould you want a doctor who鈥檚 actually happy with what they do, or one who鈥檚 possibly unhappy and maybe not fully engaged in their work?鈥欌��

Most would surely prefer the former in this hypothetical posed by Njoke Thomas. But she brings it up because studies show that some young doctors regret their choice of specialty about three years into their residency.听She says of medical students, 鈥淭hey go from the conviction of wanting to be a doctor to a period of uncertainty about what kind of doctor.鈥�

Yet some 鈥渓ean into鈥� that uncertainty, Thomas has found in her own research. 鈥淭hese students make peace with the discomfort of not knowing, so they can engage in discovery,鈥� she explains. 鈥淭hey seem to learn more about themselves in the process. I would like to examine whether these students end up being much more satisfied with their careers in the long term.鈥�

In particular, Thomas studies how medical students and early-career doctors handle transitions鈥攖he points at which they must choose a trajectory (for example, when moving from school to residency), but her research is relevant across sectors, including law, architecture, finance, accounting, and management鈥攁ll of which embrace a variety of specializations. 鈥淎 lot of careers have these junctures along the road, where you鈥檝e got to make these key decisions before you can move on to the next phase,鈥� she says. 鈥淥ne reason I do study medicine is that it鈥檚 one of the oldest and most complex professions. There鈥檚 a lot there to unpack.鈥�

Thomas knows a bit about transitions herself. She was born in Brooklyn, where she lived until age three. At that point, she moved with her parents back to their native Trinidad. When she was 16, the family moved to Oakland, where she finished high school. For several years after college, Thomas worked in public health鈥攁 field in which she went on to earn a master鈥檚 degree from Harvard. The experience motivated her to study organizational behavior for her doctorate. In her most recent transition, Thomas comes to Boston College after three years as a postdoc at Wharton.听

Areas of Interest: Asset pricing, financial intermediaries, insurance, climate finance

Toumas Tomunen studied 鈥渃atastrophe bonds鈥� for his dissertation. 鈥淗urricanes and typhoons can have devastating local consequences, with relatively minor impacts elsewhere,鈥� he says. 鈥淭his creates a great opportunity for risk sharing.鈥� Catastrophe bonds are assets that allow investors to trade and share the risks from hurricanes, wildfires, and other natural disasters.

That鈥檚 one way financial markets can mitigate the economic impacts of climate change, Tomunen says. But the markets can also help reduce carbon emissions in the first place, by allocating capital toward renewable energy. A promising instrument that Tomunen has studied is the 鈥済reen bond,鈥� whose proceeds are earmarked for climate-related investments.

鈥淐limate change is a major challenge of our time,鈥� Tomunen says. 鈥淚t takes multidisciplinary expertise and capabilities to tackle.鈥�

A former second lieutenant in the Finnish navy, Tomunen hails from the small town of Uusikaupunki. 鈥淭he literal translation of the name is 鈥榥ew town,鈥欌�� he says, 鈥渆ven though it鈥檚 more than 400 years old.鈥�

Tomunen鈥檚 wife, Mari, teaches a course on cryptocurrencies at Boston College Law School.听

Areas of Interest: Information disclosure and its implications for decision-making and resource allocation

Miao Liu studies how people process information differently than do machines. In his dissertation, Liu examined the subtle trade-off between our human weaknesses in processing hard information and our strengths in acquiring soft information.

In distilling hard data, 鈥淚 found that humans use mental shortcuts,鈥� says Liu, 鈥渃ausing biases and misperceptions.鈥� For example, loan officers in his study paid too much attention to salient features of borrowers鈥� applications, such as large jumps in cash flows.

鈥淗owever, loan officers also produce the most useful soft information by talking to the borrower in detail after they see salient hard data,鈥� Liu goes on. 鈥淓ffectively, salience, while creating bias, also gives loan officers a hint on where to look for more soft information. In a sense, human strength and weakness are two sides of the same coin.鈥�

As a high schooler in Beijing, Liu taught himself English with the help of repeated viewings of the TV show Friends. Now in the States for more than a decade, he enjoys traveling the country with his family. 鈥淚 do not need a map while in the Yellowstone and Grand Teton National Parks,鈥� he says.

Dmitry Mitrofanov

B.S., Moscow Institute of Physics and Technology
Areas of Interest: Machine learning, data-driven modeling, retail operations, sharing economy, revenue management

Dmitry Mitrofanov has unearthed insights about the sharing economy in general and ride-hailing services in particular. For one thing, customers seem very loyal to one ride-hailing service or the other, he has found. For another, price-reduction promotions have a positive short-term effect on riders鈥� preferences but a negative long-term effect. 鈥淭his might be the case because promotions induce deal-seeking behavior in users,鈥� he says. Customers once loyal to Uber, for example, might start exploring promotions with Lyft or another competitor, and even switch back and forth between the services for better deals.

鈥淪haring economy platforms have dramatically reshaped industries in nearly every corner of the world,鈥� says Mitrofanov. As platforms such as Airbnb (apartment sharing), Getaround (car-sharing) and Lending Club (peer-to-peer lending) have become ubiquitous, so have new tech twists on classical problems within operations, such as demand forecasting and running promotions. Mitrofanov relishes figuring out how companies that employ sharing technology can solve those problems.

Along with research, 鈥淚 consider teaching a fundamental, exciting, and gratifying part of academic life,鈥� says Mitrofanov. 鈥淭he most rewarding part is realizing that the course indeed prepared students with the ability to make real-world business decisions in professional environments. The most fun part is when I can use my own research to better explain some concepts in the class.鈥�

A native of Cheboksary, Russia, Mitrofanov enjoys playing tennis, swimming, and running.

As a young girl in Maine, Aimee Hoffmann Smith towered over her peers. (She eventually grew to six feet.) This height once aided her at the beach, when, at age seven, she saved the life of a drowning 10-year-old boy.

Coming of age during the Enron and WorldCom scandals fed Smith鈥檚 interest in corporate misconduct and corporate governance. 鈥淚 was intrigued by the countless examples of deceptive and intentional acts by business leaders that cost their shareholders millions,鈥� she says. 鈥淭his seemed incredibly counterintuitive to me, considering that the ultimate goal of financial management is to maximize shareholder wealth.鈥� She went on to research the topic as a doctoral student and, later, as an assistant professor at Bentley University, contributing to findings on the impacts of securities litigation on reputation and external financing.

As an educator, Smith enjoys seeing her students progress in their understanding of finance over the course of a semester, 鈥渆specially when struggling students manage to overcome personal hurdles and raise themselves to new levels of achievement,鈥� she says. 鈥淚 also love when former students contact me years after taking my class to share updates about their life events and impressive accomplishments.鈥�

In her spare time, Smith says, 鈥淚 enjoy traveling, chasing around my two- and four-year-old sons, spoiling my two elderly dogs, and feigning interest in my husband鈥檚 favorite sports teams. Go Cubs!鈥�

Areas of Interest: Competition between US firms and its implications for macroeconomic and asset pricing

鈥淥ver the past 30 years, workers have continued to produce more and more, but their wages have remained flat,鈥� Simcha Barkai said in a听. Why the gap between productivity and wages? More concentration and less competition, suggests Barkai鈥檚 research. In industry after industry, the four largest firms have come to dominate the market, enabling them to boost profits while cutting costs, leading to a decline in labor鈥檚 share of the economic pie.

In his study 鈥淒eclining Labor and Capital Shares,鈥� focusing on nonfinancial companies in the U.S., Barkai showed that over the past three decades, the share of revenues going to profits has risen by 13.5 percent, while the share going to labor has declined by 6.7 percent. The share going to investment (e.g., R&D) has declined as well, by 7.2 percent. In his paper, Barkai called this an 鈥渋nefficient outcome鈥� for the economy.

鈥淚f we can increase competition to [levels] that existed in the 1980s, wages would increase by about 20 percent,鈥� Barkai said in the video interview. His research has also been reported on by the New York Times, Wall Street Journal, the Economist, Bloomberg, Forbes, and the Washington Post, among others.

Barkai has lived in Jerusalem, New York, Chicago, and, most recently, London, where he taught finance at the London Business School for three years. In his spare time, he enjoys playing basketball and chess.听

Areas of Interest: Managerial and financial accounting

Ever since middle school, Doris Kelly knew she wanted to be an accountant. 鈥淚 was always very analytical and fascinated with the world of business,鈥� she says.

Today, Kelly can boast more than three decades of experience in the corporate world as a certified public accountant. Moreover, she served on the board of the Institute of Management Accountants, and currently serves as an advising CFO to small companies.

But Kelly is most proud of her achievements as a teacher. She comes to Boston College after a decade at Bentley University, where she was a faculty advisor as well as a lecturer.

鈥淣othing compares to getting an email from a former student telling you how much you affected their lives in a positive way,鈥� says Kelly, who garnered Bentley鈥檚 Innovation in Teaching Award in 2017.

Students are often surprised to learn that Kelly鈥檚 first language was French. Though she was born in Waltham, Massachusetts, her parents were French Canadians from New Brunswick.

鈥淲hether you鈥檙e into writing Linux code, printing stuff on your 3D printer, customizing a pair of Vans sneakers, or creating your own TikTok videos, there have never been so many different ways to create original content and share it with the world,鈥� says Matthew O鈥橦ern, who studies customer co-creation. 鈥淚t鈥檚 fun and exciting to work on a topic that is always evolving and that really focuses on the creative side of digital marketing.鈥�

In customer co-creation, companies include the consumer in product development, as in the examples above. The process can extend to troubleshooting, as well. In a recent study on the topic, O鈥橦ern and colleagues found that in certain cases, customers who experience a service failure prefer to receive service support from a fellow customer, rather than from a firm employee. 鈥淗elp offered by a fellow customer gave the affected consumer a greater sense of community support,鈥� O鈥橦ern explains.

Besides research, a major reason O鈥橦ern decided to become a professor was the chance to guide students and prepare them to accomplish their career goals. 鈥淭he aspect of teaching that is most rewarding is when I can introduce my students to a new approach, tool, or idea that they can directly apply in their internships or full-time jobs and that they can use to set themselves apart from other job candidates,鈥� said O'Hern, who previously taught marketing at the University of New Hampshire.

A native of Sioux City, Iowa, O鈥橦ern has lived in France, Germany, and Austria, where he met his wife. Following Austrian tradition, the couple held two weddings鈥攁 church wedding and a civil ceremony. Groom O鈥橦ern planned the latter. 鈥淲e said our vows in a limo at a drive-in wedding chapel in Las Vegas. It was the first time that her parents and my parents had ever met, and I have to say that this was a great call,鈥� he says. 鈥淭he wedding took 15 minutes to organize, everybody had a good time, and there was zero drama. I鈥檇 call that a win!鈥�
