JACOB GOLDSTEIN, BYLINE: Just a quick warning - there is some bad language in today's show.


A couple years ago, Alice Wu was an undergraduate at UC Berkeley studying economics. And one day, some of her friends told her, hey, you should check out this thing we just found. It's called the Economics Job Market Rumors forum.

ALICE WU: They knew, like, I wanted to do a Ph.D. in economics. And they told me - they were half joking like, oh, this would be, like, your future colleagues and stuff.

HELM: So Alice was like, sure, fine. She went to the website, clicked through a few threads.

WU: I was just surprised or, like, really in shock when I saw those comments just kind of pointed directly to a very hostile environment.

HELM: This forum had originally started as a place for Ph.D. students to swap information about the job market - who got an interview, who got hired. Then people started using it to, like, argue about nerdy econ research things, you know, like, Coase's theorem is highly overrated, that kind of thing. But it's an anonymous online forum, meaning that soon it became pretty much the worst place you can imagine - at least parts of it did. And Alice stumbled into some of that stuff.

WU: Locker room talk of something or, like, a boys club or something like that. It could get very disgusting very quickly (laughter).

HELM: Now, numbers-wise, economics is kind of a boys club. There's this stark gender gap in the profession. For example, in the U.S. in 2018, just 17% of full professors in economics were women. At the undergrad level, only about a third of all econ majors were women even though more than half of undergraduates overall were women. So for Alice, all of that is kind of just part of the scenery. And this nasty stuff she's reading on the forum, she doesn't really dwell on it. She gets out of the forum pretty fast.

WU: So I was like, maybe this is one of the dark secret in the profession, but I didn't really think too much about it.

HELM: Until a couple months later. She was in a meeting with her adviser.

DAVID CARD: Alice was in my office to chat a little bit about ideas for a senior theses.

HELM: This is David Card. He's a big shot labor economist - first met Alice when she was a student in his advanced econometrics class. So they were sitting there in his office batting around ideas for her thesis when the phone rang. David picked up.

CARD: It was an old friend of mine who was actually the chairman at the Princeton economics department, Janet Currie. And Janet was quite upset, to tell you the honest truth.

HELM: Upset because she had been reading that same forum. She was familiar with the place, and she was fed up with it because...

CARD: There seemed to be a very persistent pattern that basically there was a lot of negative stuff being said about female economists.

HELM: He hung up the phone.

CARD: And after I got off the phone, I kind of mentioned this to Alice. And I said this is - you know, this is what we were just talking about because she'd been sitting there.

WU: And then he asked me like, oh, do you know about the Econ Job Market Rumors forum? I say I heard about it.

CARD: So I wouldn't have thought she would know about it. It turns out, I guess, people know more stuff than you think they know.

HELM: Alice told me she thinks pretty much everyone in economics has been on this forum at one point or another. So she and David start talking about it.

CARD: This looks like a, you know, pretty terrible situation. And I'm not exactly sure how we got to this point.

WU: I think he say maybe you could just write a small report, like a 10-page report of what's going - what the forum is like.

CARD: See just exactly what was the pattern. Was there any really difference in how people were talking about female vs. male economists?

HELM: This is the place where I think economists diverge from normal people. For most people, here's how this story goes. You log onto an anonymous online forum, see a bunch of sexist garbage and say, well, it looks like people on this forum are being sexist - case closed. But a lot of economists don't see the world this way. They have, in the words of one economist I talked to, a bias against bias, this deep-seated belief that often things that look a lot like discrimination can be explained in other ways. So what Alice Wu set out to do was to use the tools of economics to test for bias on because, as an economist, she couldn't be sure it was there until she wrote a rigorous, replicable, statistically sound quantitative economics thesis about it. She and David Card - they're data people.

CARD: It would be probably important just to establish the facts.


HELM: It did turn out to be important. Alice Wu ended up writing her undergraduate senior thesis about this forum. And the paper, which proved something so obvious that Alice herself almost blew it off, that paper became one of the most talked about economics papers of the year. The New York Times wrote about it. One economist called Alice the most important economist of 2017. And some of the most famous people in the profession, women who have been economists for decades, say Alice's work is helping them to finally talk about big problems in economics.

Hello, and welcome to PLANET MONEY. I'm Sally Helm. Today on the show, a young economist holds a mirror up to the field and her colleagues don't like what they see.


HELM: We'll get back to Alice Wu in a minute. But first, this idea in economics that things that look like discrimination might not actually be discrimination, where does that come from?

BEATRICE CHERRIER: Can you - can you hear me?

HELM: Yeah. Can you hear me?


HELM: I called up Beatrice Cherrier. She's a historian of economics. And she told me that there was this one theory of discrimination that emerged in the 1950s. In later decades, it became a dominant theory, and a lot of people are still into it today. It was applied to racial discrimination and sexism. And economists who believe this model think about discrimination in the labor market basically this way - in a perfectly competitive world, discrimination is terrible for business. Say you're a sexist manager. You just don't like women. Some economists would call this animus. You have animus towards women. So you'll hire a less competent man rather than a more competent woman. Then you'll fall behind your competitors. If you're a business, you'll make less money. If you're an economics department, your reputation will suffer. Discrimination is inefficient.

CHERRIER: So because it's inefficient, market dynamics are going to push these people who have a taste for discrimination out of the market.

HELM: So basically, it's going to get competitioned away.

CHERRIER: Yeah, exactly. So you don't need to do anything about discrimination because it's going to disappear.

HELM: And if, say, gender disparities don't disappear, maybe that's OK. Maybe women don't want to enter the workforce.

CHERRIER: Women stay at home because it's a rational calculus. It's specialization within the household. So it's derived from their preference. You know, it's their choice.

HELM: Back in the 1970s, a group of female economists said, look; our preference is to be economists, and we think we're not getting the opportunities we should. Econ departments should actively encourage women grad students, like, whether or not they're married or have kids. But some economists didn't want to do that. Beatrice told me there are letters from this time where Milton Friedman, one of the most famous economists in America, was arguing against it.

CHERRIER: He's explicitly applying his thinking about the labor market and how the labor market worked to the problem of women in economics.

HELM: But around the same time, the 1970s, economists are developing a new theory of discrimination. And this new theory is sort of about information. These economists are like, maybe it's not animus. Maybe discrimination happens because employers are making bad assumptions based on imperfect information. So they look at the world, see that men are publishing more economics papers than women, say, and then when they're hiring an economics professor, they look at their job candidates and are like, I guess I should hire a man because, on average, men publish more. It's called statistical discrimination - discrimination based not on animus but on statistics.

CARD: So economists can spend hours on the philosophy of how those two things are different. I personally don't get it, but, you know, I'm almost ready to retire, and everybody's talked about that forever, so...

HELM: This is David Card again, the big shot labor economist who was Alice Wu's adviser. He told me that both these models have a lot of clout today. And he says, to be fair, one reason economists care about the difference is because it might affect what you do about discrimination. Like, in this statistical discrimination model, maybe you can solve the problem by giving employers more information about how women are actually great economists. And if they don't have animus in their hearts, that information might convince them not to discriminate. So maybe we can do something about this. And yet...

WU: I was just surprised or, like, really in shock when I saw those comments.

HELM: There are also places like In fact, anyone who's ever been on the Internet might think animus seems to be out there. Now, David Card is part of a big group of labor economists who say basically we don't need to keep endlessly arguing about why discrimination is happening. Let's just go out into the world and get data, document the facts. And that's what his student, Alice Wu, set out to try. Remember; she wanted to know if there was a difference in the way men and women were being talked about on this forum, a difference she could prove. And her first step was basically to write a computer program that would download the posts from the forum - all 2,217,046 of them.

WU: So after you scrape the data, it's kind of just in very messy form, so it's all, like, post after post.

HELM: Now she has to figure out how to sort these posts into buckets. One bucket is posts about men. One bucket is posts about women. And to sort them, her first step is to pick out words that clearly refer to gender.

WU: Most straightforward ones are pronouns, like she or he, him or her. There are also other general ones, like female, male, woman, man.

HELM: I think I remember from your paper that there was also bro and broette. Is that right?

WU: Yes.

HELM: She also picks out names, classifies those as male or female. And once she has this initial list of words, some of the posts are super easy to classify. Like, if the word he appears 20 times in a post and the word she doesn't appear at all, it's probably a post talking about men. It goes in the male bucket. And she takes those posts, the ones that are obviously talking about men or obviously talking about women, and she analyzes them using machine-learning tools and gets a list of other words, words that come up disproportionately in posts about women or posts about men. Alice read through that list.

WU: My first impression was obviously they were bad, but if you are familiar with the forum and look at those posts, it wouldn't be something surprising.

HELM: She went to an advising meeting with David Card. And at some point, she offhandedly showed him the list.

WU: And I just show him, like, oh, hey, this is a list of words. And he was like, why didn't you show it to me earlier?

HELM: David Card immediately knew that this list - it wasn't just, like, preliminary data. It was a finding in itself because when Alice showed him this list, he didn't even want to read the words out loud while Alice, a student, was sitting there in his office.

CARD: You could imagine a situation where a male - older male professor is showing a list of words like that to a younger female student. And I could lose my job. I wasn't that worried about it, but I was aware that, you know, we're not going to say those words out loud in my office.

HELM: I pulled up the latest version of Alice's paper while we were talking.

Can we look at the words?

WU: Oh, yeah.

HELM: Let's pull them up. Wow. OK. Would you mind reading them to me? You don't have to. If you don't want to, that's OK. But will you?

WU: Actually, I wouldn't want to.

HELM: So I read some of them.

Yeah, pretty terrible. Let me see - blond, unattractive, gorgeous, assaulted. There's also naked, whore, plow, raped, vagina, ugly, some less offensive but still not great ones, like pregnant and marry. Now, to be fair, there are some disturbing words on the male list, too. The top word most disproportionately associated with posts about men is homo. The second is testosterone. And along the way, there were also some words that were just confusing.

Why is salmon one of the most male words?

WU: I think they're talking about food.

HELM: Why is mountains on there?

WU: I have no idea.

HELM: To Alice, the main distinction has to do with which of the words are professional and which words are personal. Notably, none of the words that were disproportionately associated with women have to do with economics, but words disproportionately associated with men included things like macroeconomics, Keynesian, adviser, Nobel. This list ends up becoming a big part of Alice's senior thesis, and it's a part that people in the economics profession have really grabbed on to.

Now, I should say that this study is narrow. It has limitations. For one thing, the posters are anonymous, so we don't know who is saying all this nasty stuff or how many people are saying it. And remember, this is about how disproportionately these words come up in posts about men and posts about women, not how frequently they come up. So for example, out of 400,000 posts that Alice analyzed, the word ugly comes up 1,046 times in posts about women and 404 times in posts about men.

David Card has studied discrimination for years, and he says...

CARD: One reason why Alice's paper is important is because it identifies animus.

HELM: Animus - so not people just need a little more information and then they'll do the right thing, but animus - hostility, meanness.

CARD: This demonstration on Econ Job Rumors says that there's really something to animus. It's not that everybody has a pure mind and is just saying, oh, I really wish I could hire women, but, you know, they're just not that good. This is like, oh, my God, these guys are going out of their way to trash women.

HELM: Now, of course, Alice's paper does not prove that there's hiring discrimination happening in economics. These posters could just be a tiny slice of troll-y Ph.D. bros who don't have any real clout. And it might have become just a really good senior thesis that helped Alice Wu get into grad school. But that's not what happened. After the break, Alice's paper blows up.

So Alice finishes her senior year of college. Second semester, her thesis is done. She's gotten into Harvard for grad school. She can relax a little.

WU: I actually discover my interest in beer.


HELM: Her thesis wins a prize. And over the summer, she gets an email. Economist Justin Wolfers wants to write about her paper in The New York Times. Alice ultimately says OK, even though she's nervous.

WU: It was, like, a lot of pressure, for sure. It was like, this was the first economics paper I ever wrote. Like, I don't know.

HELM: But she agreed to do it. When the New York Times piece came out, the reaction was huge. Economists spoke out online, at conferences. They sent emails to Alice. They were sharing personal experiences with sexism in the field.

WU: People start talking about those, you know, more openly. So I think that the forum is definitely problematic, but it reflects something much larger than the forum itself. It just basically reflects the gender issues in the profession.

HELM: One place where Alice's paper was big news was at this annual meeting of economists, the meeting of the American Economic Association, the AEA. The AEA is a big deal. For one thing, this conference is where grad students interview for faculty jobs. It's where fancy new papers get presented. Alice spoke on a panel at the AEA conference in 2018. And around that time, she did something that made her a little anxious. She searched her own name on the forum.

WU: Once they knew, like, I'll be presenting at this session, there were just some really, like, weird comments. They were like, oh, we are going to stalk her or something. That was really scary. It didn't turn out to be that way at all.

HELM: Alice presented her paper alongside several other female economists who have studied women in the field, Erin Hengel, Betsey Stevenson and Tatyana Avilova. When The New York Times wrote about this panel, their headline began, "Wielding Data, Women Force A Reckoning Over Bias."

And it seems like data has really convinced a lot of economists that they have a problem. The AEA actually did a big survey this past year to get more and more comprehensive data about the culture in economics, not just about sexism. They also asked about racism and about sexual harassment. And the surveys show that racism and sexism and harassment are a problem in the field. Predictably, it also showed that not all economists see the problem in the same way. For example, 52 percent of men who took the survey agreed that women are respected in the field. Only 16 percent of women agreed.

I wanted to talk to someone from the forum who had read Alice's paper and see if it changed their mind. So I made an account on I searched Alice Wu, and I posted on one of the threads about the paper. Hey, I'm a reporter. I told people to get in touch if they were willing to talk. I'm going to hit this button. It says send post. I didn't specify my gender, by the way, because I was nervous. I did it. OK. There it is. Oh, my God. We'll see what happens.

Pretty soon, I got the first response. It starts, lol, yeah, right. The person didn't believe I was a real journalist. They went on to say, let's face it, lies sell better than the truth. And even if by some miracle this person - aka me - was concerned about the truth, we all know that this person lacks the technical knowledge to understand any of our explanations of why the paper is wrong. There were a few other responses, too, some of them nicer. But basically, Alice's paper didn't convince everyone. After all, this idea that competition should help get rid of animus, of discrimination, so maybe we don't have to worry about it - that idea has been around a long time. Lots of economists still believe it.

At the big annual meeting of the AEA this past year, people were confronting this head-on.


BETSEY STEVENSON: OK. Welcome, everyone. Thank you for coming out at 8 a.m.

HELM: This is Betsey Stevenson, an economist at the University of Michigan. She's sitting onstage with a bunch of famous economists, all women.


STEVENSON: Economists sort of come to the field with a prior that there's no discrimination. And they're only going to move their prior when confronted with some sort of compelling evidence. My question to the panel is, how can we best address those who are the most skeptical that there's any kind of problem with discrimination in the field?

HELM: One of the economists onstage is Susan Athey, Stanford professor.


SUSAN ATHEY: People have this habit of making these statements that, to me, seem somewhat ridiculous, like, oh, you know, this can't be an issue, it gets competed away, et cetera. And, you know, I don't really want to get in that argument. I might get emotional. I might lose my temper. I might never think about that person the same way. And so it's really very risky, I feel, still, to start these conversations. And so I want to make sure that when I answer, I'm going to be answering in the economic way with the evidence, with the data. So thank you, everyone who's given me data, you know, because it's very hard to talk about.

HELM: Also onstage, Janet Yellen, the only woman ever to chair the Federal Reserve, which is arguably the most powerful economic policy job in the world.


JANET YELLEN: You know, you asked, Betsey, why it's so difficult to convince men. I think they regard themselves as rational and the field as being highly meritocratic, and it does require some evidence.

HELM: You know what evidence Yellen was particularly impressed by?


YELLEN: I think we got that evidence in the Alice Wu paper. I think that was a remarkably convincing, appalling finding. I haven't heard any man say, oh, that's all fine, and it shows us our field is functioning well and properly.

HELM: Janet Yellen will take over as head of the AEA next year. And the AEA has definitely been making some changes. Among other things, they adopted a professional code of conduct. It's the first time they've done that. They plan to start new programs aimed at getting more women and people of color into economics. They've also started an alternative to, their own forum. It's called EconSpark. Alice told me that not that many people seem to be using it.
