This is a transcript of the Freakonomics Radio podcast “The Tax Man Nudgeth.”
Sarah GARDNER: It’s Freakonomics time. Every couple weeks, we’re talking with Stephen Dubner, co-author of the books and blog about “the hidden side of everything.” Stephen, it’s good to talk to you.
Stephen J. DUBNER: It’s great to talk to you, Sarah. Thanks for having me. It is April, which is every taxpayer’s favorite month, of course. I thought today what we should do is take a look at the tax code we’re stuck with for now and see if there are some improvements, however slight, that we should be thinking about.
GARDNER: OK. So what kind of things are we talking about here?
DUBNER: Well, one of the biggest failures of the current system is also the most obvious: the I.R.S. fails to collect a huge portion of the taxes that are levied — that are legitimately owed. So about 17 percent of the total tax bill, which is more than $450 billion a year.
GARDNER: Whoa! What? Say that again. 17 percent! That’s pretty astounding.
DUBNER: It’s a big number. It’s called the “tax gap.” It’s about $450 billion a year. The biggest contributor to this gap, by far, is very simple — cash. It’s all the cash that people earn and simply don’t report to the I.R.S. Austan Goolsbee was the top White House economist under President Obama. We asked him why the government doesn’t go after all that easy money.
Austan GOOLSBEE: Most of the non-collected money, for example, could be tracked and hunted down if you required small businesses to really report everything about their activity. But nobody wants to do that because it would be so onerous and such a pain in the rear for small business owners that, as a policy decision, they don’t want to do it.
GARDNER: So, in other words Stephen, politically it’s too dangerous. It’d be like “The Small Business Harassment Act” if they went after small businesses really hard.
DUBNER: Exactly. Even though these people are supposed to be paying taxes on that money. And even though, interestingly, the rest of us, who don’t pocket a lot of unreported cash — we’re subsidizing them. That’s not to say there aren’t ways to nudge people to pay their taxes without “hunting and tracking them down,” as Austan Goolsbee says. One of my favorite examples of this comes from a small unit in the British government called the Behavioral Insights Team. What they do is experiment with all kinds of cheap and simple nudges. For instance, sending out letters that appeal to the herd mentality in all of us. Here is the unit’s director, David Halpern:
David HALPERN: So what we do is we simply tell people something, which is true, which is 9 out of 10 people in Britain pay their tax on time. And by putting that single bit of information into the top of a letter, it makes people much more likely themselves to pay the tax on time.
GARDNER: So it’s peer pressure?
DUBNER: That’s exactly right — we like to run with the herd. They also tried another super simple trick, which was just handwriting a message on the outside of the tax envelope. This message would just say simply that the contents are important, but it’s written in hand.
HALPERN: Of course people are like ‘oh my God, but how can that possibly be practical?’ Well we’ve now just got the results in. It turns out that for every pound or every dollar that you spend on getting, you know, someone to write on the envelope, you get $2,000 return. A one to 2,000 return. So it’s a nice simple illustration of these small things and how consequential they are.
GARDNER: So it sounds like peer pressure and the personal touch. Those aren’t bad ideas, really.
DUBNER: They’re great ideas. They’re small. They’re on the margin. They also have the collective result of trying to make tax paying a little bit more, I don’t know if fun is the right word. But the way the tax system is currently set up, we see paying taxes as pure downside. Right? Not only does it cost us money but on top of that, it’s complicated, it gives us angst. And, maybe worst of all, any given person has practically no say in how your hard-earned tax dollars are actually going to be spent. Right? Dan Ariely, a behavioral psychologist at Duke, has a nice idea: to let taxpayers direct a small portion of their tax money to the parts of the government that they most care about:
Dan ARIELY: So I’m not sure what’s the right percent — five percent or ten percent. But what if we got people to have a say about where some of the taxes go? All of a sudden you’re not looking at it as you against the government. You’d have to look carefully at all that the government is doing for us — building libraries and roads, and education and military and so on and so forth and say, what do I care about?
GARDNER: I don’t know about that! It would be fascinating to see how many people would really want to say, ‘gee, I really want to put more money into defense.’ Or Medicare. You know?
DUBNER: A lot of military families out there feel like the military gets the short shrift. But the first thing you said — I absolutely agree with. We don’t really know, because we’ve never really asked and we’ve never really given the opportunity for people to say.
GARDNER: So Stephen, what about you? Where would you put your five or ten percent?
DUBNER: Oh, I think that’s pretty obvious, Sarah, don’t you think? I’d send it to a slush fund for people who make radio about economics.
GARDNER: Oh, OK! Stephen Dubner, our Freakonomics correspondent. He puts out a podcast, too — you can get that on iTunes and hear more at Freakonomics dot-com. Stephen, it has been a pleasure.
DUBNER: Thank you so much.
DUBNER: Hey podcast listeners. You heard a little bit in this episode from David Halpern, who runs the British government’s Behavioural Insights Team. They are more informally called the “Nudge” Unit, after the book Nudge by the American academics Richard Thaler and Cass Sunstein. Halpern himself is an academic, very well-regarded, and it’s encouraging — to me, at least — to see him putting so many academic ideas to work in a government job. So let’s hear a bit more from our interview with Halpern. Here he is talking generally about the Nudge Unit’s mission:
HALPERN: Well, we think that if you have a more nuanced understanding of how people actually make decisions or what drives behavior, you can design policy that’s better, it’s cheaper, it’s easier, it’s more effective for people. And so for example, people often worry about, you know, how we can use a tax subsidy to get more people in employment or saving or whatever it will be. We’re obsessed about the tiny details. We’re obsessed about the little inconveniences and hassles that get in the way of people being about to do things, which maybe traditionally got a lot less attention not only because they can often be annoying for citizens, but if you can get rid of those frictions, those details, those problems, everything works better.
DUBNER: So the Nudge unit nudges people — with experiments, with clever incentives, often in areas that most of us don’t give much thought to. Attics, for instance.
HALPERN: One nice one we tried may appeal to people over there is that very large numbers of people haven’t insulated their homes enough in Britain. And even though for years we offer great big subsidies to encourage people to insulate their home, the interesting thing about this is it’s a no-brainer as we would say. You know, you get your money back in the first year, so why don’t people insulate their lofts? Their attics I guess you’d call them. And of course when you look into the reason why most people don’t do it is because their attic’s full of stuff that they should have thrown out years ago. And that’s the real reason. So giving them ever bigger subsidies doesn’t work very well. So we ran a trial instead by offering an attic clearance scheme, which by the way they have to pay for, but it’s fine. And hey, we found that that increased by three to five-fold the uptake of people getting their attics insulated. And it didn’t require more money or subsidy from government, it just required offering this service in a way which was convenient for people.
DUBNER: Maybe it’s just his accent, I don’t know. But Halpern strikes me as quite clever, and also wise. Also, there’s the novelty — of hearing about a government trying to make life simpler for its citizens rather than more complicated:
HALPERN: Well I hope for many people their experience for this ultimately is it will just be easier, just life will be easier. Instead of thinking of your taxes as, I mean, fine no one wants to pay their taxes probably, right? At least let’s make it as easy as possible and as frictionless as possible. And you get letters which are tailored to you and so on. So you’ll get a sense of government, which is really efficient and effective in the way it operates in its details. And that’s true of course particularly around big areas of policy be it from, you know, boosting economic growth or improving fuel efficiency, or a million other things.”
DUBNER: So that was David Halpern from the British government’s Behavioral Insights Team. Coming up on the next Freakonomics Radio, we ask a seemingly simple question: how much does your name really matter? From the unusual names:
DUBNER: Can you give us your full name?
YO: Yeah, sure. Yo Xing Heyno Augustus Eisner Alexander Weiser Knuckles Jeremijenko Conley.
DUBNER: To the black and white names:
SWEENEY: Molly, Amy, Madeleine, Caitlin and Emma.//Imani, Ebony, Precious, Deja, and Diamond.
DUBNER: To the red and blue names
OLIVER: In the conservative house the girls would have names like Casey, McKenzie, Jordan, Taylor and Sarah. In our liberal house, they would have names like Lola, Mia, Thea, Eliana, and Ruby.
DUBNER: Everybody’s got a name. What does yours say about you? That’s next time on Freakonomics Radio.
