Al Roth on Matching Markets
The system that runs the ride-sharing company Uber doesn’t just link up passengers and drivers based on price. It also has to connect the two based largely on where they are geographically. It is, says Nobel laureate Stanford economist Alvin E. “Al” Al Roth, a matching market.
In this Social Science Bites podcast, Roth explains to interview David Edmonds some of the ins and outs of market matching, starting with a quick and surprisingly simple definition.
“A matching market is a market in which prices don’t so all the work,” Roth details, “So matching markets are markets in which you can’t just choose what you want even if you can afford it – you also have to be chosen.” But while the definition is simple, creating a model for these markets is a tad more complex, as Roth shows in offering a few more examples and contrasting them with commodity markets.
“Labor markets are matching markets. You can’t just decide to work for Google – you have to be hired. And Google can’t just decide that you’ll work for them – they have to make you an offer.” And like say university admission, matching markets require something to intervene, whether it be institutions or technology, to make this exchange succeed. In turn Roth himself helped engineer some high profile matches in areas where the term ‘market might not traditionally have been used: kidney donors with the sick, doctors with their first jobs, or students and teachers with schools. Or even the classic idea of ‘matchmaking’ – marriage.
Roth turned to game theory to help explain and understand these markets, and his work won he and Lloyd Shapley the 2012 Nobel Memorial Prize in Economic Sciences. As the Nobel Committee outlined:
"Lloyd Shapley studied different matching methods theoretically and, beginning in the 1980s, Alvin Roth used Lloyd Shapley's theoretical results to explain how markets function in practice. Through empirical studies and lab experiments, Alvin Roth demonstrated that stability was critical to successful matching methods."
Roth is currently president of the American Economics Association, and sits as the Craig and Susan McCaw professor of economics at Stanford University. He is also the Gund professor of economics and business administration emeritus at Harvard University

Under normal circumstances, if something was hurting you, you’d likely stop doing it. Except, well, as Theresa Marteau of Cambridge University’s Department of Public Health and Primary Care has explored deeply, in some key areas, you’re likely not stopping.
In a conversation with Social Science Bites host David Edmonds, she notes that the majority of premature deaths are due to four non-communicable diseases – diabetes, cancer, cardio-vascular disease, and lung disease. In turn, there are four main causes of these diseases – smoking, overconsumption of food, alcohol, and not moving around enough. All those causes, you’ll notice, flow from behavior.
And simply tapping someone on the shoulder and pointing out the connection has not been a particularly effective way to interrupt these pernicious behaviors.
“It’s quite a common idea that if people only understood better how they might be damaging their health, then they would tackle it,” Marteau explains. “Governments and others invest an amount of money in trying to communicate the risks to you and your health of engaging in these behaviors ... and while it can raise awareness, it’s not that effective at changing your behavior.”
That’s perplexing, Marteau admits, but undeterred she’s spent much of her career at the intersection of basic psychology, neuroscience and behavioral science looking for ways that do work to change behavior. And, as this podcast explores, she’s focused on the environment.
Or rather, environments.
As director of Studies for Psychological and Behavioural Sciences at Cambridge’s Christ’s College, her research group examines how environment – and that includes the cultural, built and financial environments --buttresses short term pleasures over long term benefits.
Taking a cue from Daniel Kahneman’s Thinking Fast and Slow, Marteau finds that the ‘bad’ behaviors in question ultimately—despite any initial enthusiasm at some point to quit smoking or go to the gym – default to the so-called ‘fast‘ brain system that oversees routine behaviors. These routines in turn are shaped, or perhaps amplified, by those environments.
Ultimately, Marteau focuses on addressing these harmful behaviors, work which this June saw her named Dame Commander of the Order of the British Empire for her services to public health. That work has her collecting evidence for redesigning environments to promote healthy behavior, which touches on public and private industry issues like product pricing, availability (and proximity), portion size, excise taxes, and many others -- “conceptually simple but legally and culturally more complex,” she admits.

“Borders,” says Mary Bosworth, “are the key issue of our time.” And so, says the criminologist, “in response to the mass migration that’s happening, the criminal justice system is shifting. This shouldn’t surprise us – all other aspects of our society are changing.”
One of those changes is the creation of a new subfield of criminology, one explicitly evolved to understand immigration control and criminal justice. In this Social Science Bites podcast interview with Dave Edmonds, Bosworth talks about a field which she calls ‘border criminology.’
She starts the conversation by explaining that even the name of the field is a bit unsettled. Bosworth notes a couple of other terms making the rounds, including ‘crimmigration’ – coined by Juliet Stumpf -- and ‘criminology of mobility.’ The latter, she adds, doesn’t capture way that it’s the movement of people that’s being criminalized, and so “that doesn’t work quite so well in English.
“Border criminology as a term, I think, captures more clearly the way in which this is a field of study which is trying to understand both things that are happening at the border but also things that are happening n our criminal justice system.”
Border criminologists as a class do lots of field work in places like courts and prisons, and in Bosworth’s case much of her recent work has been in Immigration detention centers, which in the United Kingdom hold about 32,000 foreign nationals.
One of the main takeaways from her research has been that these detention centers are “very painful places for all the people concerned” – whether detainees and the officers. The officers themselves often “don’t fully understand what they’re doing” and “don’t have a clear narrative” of the population they are detaining, which runs from criminals to visa overstayers to people who just don’t have any papers.
As an academic who once did research in prisons, Bosworth finds “the detention estate is much more recent and politicized -- and doesn’t have tradition of letting researchers in.”
As someone who has been allowed in, Bosworth says she’s found policymakers are interested in hearing her results, but less so on acting on them. A “counternarraitive” on the threat posed by immigrants has created headwinds, she finds, that make reforming policy difficult despite the documented fiscal and human costs of the present system.
In this interview, she also describes the emotional toll on this sort of filed work, and some of the brighter spots of her efforts, such as creating an archive of artwork made by detainees.
Bosworth is a professor and fellow of St. Cross College at the University of Oxford and concurrently a professor at Australia’s Monash University. She’s the director of the interdisciplinary research group Border Criminologies and assistant director of the Center for Criminology at Oxford. She’s currently heads both a five-year project on “Subjectivity, Identity and Penal Power: Incarceration in a Global Age” funded by the European Research Council as well as a Leverhulme International Network on external border control.

Ask a number of influential social scientists who in turn influenced them, and you’d likely get a blue-ribbon primer on the classics in social science.
Wright Mills’ The Sociological Imagination. Ernest Becker’s The Denial of Death. Irving Goffman’s The Presentation of Self in Everyday Life. Emile Durkheim’s Suicide. Michel Foucault’s The Archaeology of Knowledge.
During the recording of every Social Science Bites podcast, the guest has been asked the following: Which piece of social science research has most inspired or most influenced you? And now, in honor of the 50th Bites podcast to air, journalist and interviewer David Edmonds has compiled those responses into three collections. This last of the three appears here, with answers presented alphabetically from Toby Miller to Linda Woodhead.
“I remember as a graduate student reading classics in epidemiology and sociology and feeling like a kid in the candy store,” recalls David Stuckler, now a University of Oxford sociologist, before namedropping? Durkheim.
Several of the guests gently railed at the request to name just one influence. “There isn’t one,” starts Mirca Madianou, a communications expert at Goldsmiths, University of London. “There may have been different books at different times of my formation.”
Social psychologist Steve Reicher said he instead liked the idea of desert Island books, which give multiple bites of this particular apple, and then named several influences, including E.P. Thompson’s The Moral Economy of the English Crowd in the Eighteenth Century and Natalie Davis’s The Rites of Violence: Religious Riot in Sixteenth-Century France, which he describes as “beautiful and rich depictions of patterns of social behavior.”
“I’m unprepared to answer this!” exclaims behavioral economist and Nobel laureate Robert Shiller before he cites Hersh Shefrin and Richard Thaler’s work that pioneered the connection between neuroscience and eEconomics.
Sometimes, though, the answer comes instantly. “Not a day that I don’t think about him or talk about him to somebody,” said Lawrence Sherman of Austin Bradford Hill, an economist whose work evaluating the use of streptomycin in treating tuberculosis created the template for randomized controlled trials.

What is an “organization?” According to Chris Grey, the guest in this Social Science Bites podcast, in many ways it’s a moment in time. “An organization,” he tells interviewer David Edmonds, “is also a momentary crystallization of an ongoing process of organizing.”
Grey is a professor of organizational studies in the school of management at Royal Holloway University in London and a fellow of the Academy of Social Sciences. And while he’s been heavily involved in management studies – he’s actually part of the School of Management at Royal Holloway – he makes clear that the rubric of ‘an organization’ extends far beyond business alone. “A huge amount of life is organized,” Grey explains, “and is therefore under the ambit of organizational studies.” In fact, the field itself, which essentially emerged from work on bureaucracy by Max Weber, was usually located in an institution’s sociology or psychology departments until the advent of business schools in the 1960s exerted a magnetic draw on the discipline.
One of Grey’s best examples of not being solely a business study is detailed in his 2012 book — Decoding Organization: Bletchley Park, Codebreaking and Organization Studies — about the (now) famous British World War II codebreaking campus. As he describes in this podcast, Bletchley Park harnessed many of the current cultural trends and personality traits of its selected workforce so well that even spouses didn’t know of each other’s wartime exploits for decades after V-E Day.
Even if organizational studies is boiled down to issues of economic efficiency, he continues, “we have to open up the question of what does efficiency mean and for who?” He adds: “We needn’t give the answer, ‘efficient for the powerful’.” And while admitting that his “take” is far from universal among his colleagues, “Fundamentally the problems of organization are not soluble and they’re not amenable to the kind of prediction and control that is sometimes promised.”
While he has wide ranging research interests and a love of detective novels, Grey remains well-represented in the management field. He was editor-in-chief of Management Learning for six years. Grey co-edited the 2016 book Critical Management Studies: Global Voices, Local Accents and was co-author of another 2016 volume, Secrecy at Work: The Hidden Architecture of Organizational Life.
His most recent book for SAGE is the cleverly named A Very Short, Fairly Interesting and Reasonably Cheap Book About Studying Organizations.

How lightly, or how tightly, do you hold your values? Are there things you hold dear, which almost automatically excite your emotions, for which you would make the costliest of sacrifices?
These are the sorts of questions Scott Atran discusses in this Social Science Bites podcast. Atran is a “classically trained” anthropologist (he was once an assistant to Margaret Mead) and is the research director in anthropology at France’s National Center for Scientific Research, a research professor of public policy and psychology at the University of Michigan, and a founding fellow of the Centre for Resolution of Intractable Conflict at the University of Oxford’s Harris Manchester College. He is also director of research and co-founder of Artis Research & Risk Modeling, Artis International, and Artis LookingGlass.
As those associations suggests, much of his research sits at the intersection of violent acts and cognitive science, and much of his fieldwork takes place on the front lines of conflict. His findings are often acknowledged as true by policymakers – even as he ruefully tells interviewer David Edmonds, they generally then refuse to recognize the sincerity with which the other side holds its values.
And yet these spiritual values often trump physical ones. And from a policy perspective, say the attempting defeat ISIS in the Middle East, it helps to understand that a devoted actor will often outperform a rational actor when the going gets tough. This helps explain the initial successes of ISIS, and the ability of Kurdish forces to battle back against ISIS. Or even of the American colonies to defeat the British empire.
Atran explains that while there are no theories, at present, about sacred values, but there are features that he has been able to test for reliability.
For example, Atran suggests that something so valued is immune to trading, discounting or negotiating, and that offering to buy your way around someone’s sacred values can result in anger or violence.
He asked refugees in Lebanon and Jordan what was the chance they would go back to Israel if they had the right of return. Six percent – one out of 16 – said they would ‘consider it.’ But then they were asked if they would give up this sacred value, the implication being that if they weren’t going to exercise it why bother keeping it. Yet 80 percent answered no. Then the researchers asked if the respondents would support the 1967 boundaries of Israel, and accept a cash payment, in exchange for permanently ceding their right of return.
“Not only did they refuse,” Atran notes, “but it went to ceiling. We tested for support of suicide bombing, skin responses for emotion and moral outrage, it went through the roof.” But this allegiance to the intangible works two ways – Atran found that when a questioner acknowledged a refugee’s right of return, support for the peace process – even without any other sweetener – increased.

The Communist Manifesto. Novelist Don DeLillo’s account of a big moment in baseball. Works by Wittgenstein and Focault. And a famous –and shocking – behavioral experiment. These are a few of the supremely inspiring works which have influenced some of the leading social scientists at work today.
During the recording of every Social Science Bites podcast, the guest has been asked the following: Which piece of social science research has most inspired or most influenced you? And now, in honor of the 50th Bites podcast to air, journalist and interviewer David Edmonds has compiled those responses into three separate montages of those answers. The second appears here, with answers – presented alphabetically – from Bites’ guests ranging from Sarah Franklin to Angela MacRobbie.
Their answers are similarly diverse. Sociologist Franklin, for example, who studies reproductive technology, namechecked two greats – Marilyn Strethern and Donna Haraway -- who directly laid the foundation for Franklin’s own work. “I would hope,” she reflected, “that I could continue toward those ways of thinking about those issues now and in the future.”
David Goldblatt meanwhile, who studies the sociology of football, picked influencers whose contributions are apparent in his work but less academically straightforward. He chose The Communist Manifesto (“the idea that history was structured and organized has never left me”) and the first 60 pages of American novelist Don DeLillo’s Underworld, which describes ‘the Shot Heard Round the World,” a famous home run from baseball’s 1951 World Series. Goldblatt terms it the “greatest piece of sports writing ever.”
Other guests in this 15-munte podcast recall important studies that set the scene for their own work, or important figures that left them wanting to emulate their scholarship. And not everyone cited academics in their own fields. Witness Peter Lunt citing Ludwig Wittgenstein and MacRobbie Michel Focault, while Jennifer Hochschild named an historian, Edmund Sears Morgan. She called his American Slavery, American Freedom “a wonderful book, everyone should read it – including the footnotes.” The book’s thesis, that “you had to invent slavery in order to be able to invent liberalism,” sticks with her to this day.
Other Bites interviewees in this podcast include Jonathan Haidt, Sarah Harper, Rom Harre, Bruce Hood, Daniel Kahneman, Sonia Livingstone, Anna Machin and Trevor Marchand. To hear the first montage, click HERE.

It’s said that in the last two years, more data has been created than all the data that ever was created before that time. And that in two years hence, we’ll be able to say the same thing. Gary King, the head of the Institute for Quantitative Social Science at Harvard University, isn’t certain those statements are exactly true, but certain they are true in essence. And he’s even more certain that the growth in the amount of data isn’t why big data is changing the world.
As he tells interviewer Dave Edmonds in this Social Science Bites podcast, roughly 650 million social media messages will go out today. So to someone trying to make statements about what those messages contain, he posited, would having 750 million messages make anything better? “Having bigger data,” King says, “only makes things more difficult.”
Or to be blunter, “The data itself isn’t likely to be particularly useful; the question is whether you can make it useful.” Which leads to King’s real passion: the analysis of big data. It’s not the ‘big’ or the ‘data’ that really turns the screw; it’s the analysis.
In this conversation, King, uses text analysis as an example of this big data analysis. He notes that some of the tools that text analysis uses are “mathematically similar” to another project he worked on, trying to determine health priorities in the third world by figuring out what’s killing people there. In both cases, the individual, whether someone with a disease or someone with a viral tweet, is less important than the trend.
That, explains King, spotlights the difference between computer scientists’ goals and social scientists’ goals: “We only care about what everybody’s saying.” He then talks about work examining social media and censorship in China. While the work clearly falls into an area that King, a political scientist, would be interested in, the genesis was actually as a test case for the limitations of the text analysis program. But it nonetheless gave useful insight into both how the Chinse government censors material, and why.
King is the Albert J. Weatherhead III University Professor at Harvard. He’s been elected a fellow or eight honorary societies, including the National Academy of Science, the American Association for the Advancement of Science, and the American Academy of Political and Social Science. King also has an entrepreneurial bent – he mentions the company Crimson Hexagon that was spun out of the text analysis work during this interview – and has founded or invented technology for companies like Learning Catalytics and Perusall.
And here’s some, if not ‘big’ data, at least ‘bigger’ data, to consider: This interview marks the 50th Social Science Bites podcast produced by SAGE Publishing.

Which piece of social science research has most inspired or most influenced you?
This question has been posed to every interview in the Social Science Bites podcast series, but never made part of the audio file made public. Now, as we approach the 50th Social Science Bite podcast to be published this March 1, journalist and interviewer David Edmonds has compiled those responses into three separate montages of those answers.
In this first of that set of montages, 15 renowned social scientists – starting in alphabetical order from all who have participated – reveal their pick. As you might expect, their answers don’t come lightly: “Whoah, that’s an interesting question!” was sociologist Michael Burawoy’s initial response before he named an éminence grise – Antonio Gramsci – of Marxist theory for his work on hegemony.
The answers range from other giants of social, behavioral and economic science, such as John Maynard Keynes and Hannah Arendt, to living legends like Robert Putnam and the duo of Richard Thaler and Cass Sunstein (and even one Social Science Bites alumnus, Stephen Pinker). Some of the answers involve an academic’s full oeuvre, while others zero in on a particular book or effort. John Brewer, for example, discusses his own background in a Welsh mining town and how when he went to college he encountered Ronald Frankenberg’s Communities in Britain: Social Life in Town and Country. “That book made sense of my upbringing and committed me to a lifetime’s career in sociology,” Brewer reveals.
And not every answer is a seminal moment. Danny Dorling, for example, names a report by his Ph.D. adviser, computational geographer Stan Openshaw, who took two unclassified government reports to show the futility of nuclear war. And not every answer is even an academic work. Recent Nobel laureate Angus Deaton reveals, “I tend to like the last thing I’ve ever read,” and so at the time of our interview (December 2013), named a journalist’s book: The Idealist by Nina Munk.
Other Bites interviewees in this podcast include Michelle Baddeley, Iris Bohnet, Michael Billig, Craig Calhoun, Ted Cantle, Janet Carsten, Greg Clark, Ivor Crewe, Valerie Curtis, Will Davis and Robin Dunbar.

Human beings are social animals, notes economist Michelle Baddeley, and as such the instinct to herd is hardwired into us. And so while this has changed from (in most cases) physically clumping into groups, it does translate into behavior linked to financial markets, news consumption, restaurant-picking and Brooklyn facial hair decisions.
In this latest Social Science Bites podcast, Baddeley – a professor in economics and finance of the built environment at University College London -- tells interviewer David Edmond how modern herding often follows from an information imbalance, real or perceived, in which a person follows the wisdom of crowds. The decision to join in, she explains, is often based an astute reading of risk; as she quotes John Maynard Keynes, “It’s better to be conventionally wrong than unconventionally right.” As a real world example of that, she points to the plight of the junior researcher, whose career is best advanced by serving up their innovative insights along conventional lines.
Apart from reputational damage control, there are pluses and minuses to human herding, Baddeley notes there are advantages to finding safety in numbers: “It’s a good way to find a hotel.” But there are pernicious outcomes, too, like groupthink. In that vein, the economist says she finds partisan herding “more prevalent in a ‘post truth age,’” as individuals join thought groups that reinforce their existing world-view. And it doesn’t help, her research finds, that people are more likely to herd the less well-informed they are.
This has also had dire consequences in financial markets (Baddeley was principal investigator on a Leverhulme Trust project focused on neuroeconomic examination of herding in finance), where pushing against the grain makes for a short career for anyone other than the luckiest professional stockpicker.
Baddeley’s early education was in Australia and her first professional work was as an economist with the Australian Commonwealth Treasury. She then completed masters and doctorate work at Cambridge. Her most recent book is 2013’s Behavioural Economics and Finance and other works include Running Regressions - A Practical Guide to Quantitative Research (2007) and Investment: Theories and Analysis (2003).
