Dan Ariely and Francesca Gino are two of the biggest stars in behavioral science. Both have conducted blockbuster research into how to make people more honest, research we've highlighted on Planet Money. The two worked together on a paper about how to "nudge" people to be more honest on things like forms or tax returns. Their trick: move the location where people attest that they have filled in a form honestly from the bottom of the form to the top.But recently, questions have arisen about whether the data Ariely and Gino relied on in their famous paper about honesty were fabricated — whether their research into honesty was itself built on lies. The blog Data Colada went looking for clues in the cells of the studies' Excel spreadsheets, the shapes of their data distributions, and even the fonts that were used.The Hartford, an insurance company that collaborated with Ariely on one implicated study, told NPR this week in a statement that it could confirm that the data it had provided for that study had been altered had been altered after they gave it to Ariely, but prior to the research's publication: "It is clear the data was manipulated inappropriately and supplemented by synthesized or fabricated data." Ariely denies that he was responsible for the falsified data. "Getting the data file was the extent of my involvement with the data," he told NPR.Help support Planet Money and get bonus episodes by subscribing to Planet Money+ in Apple Podcasts or at plus.npr.org/planetmoney.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Usually, the first class that an MBA student takes is accounting. That involves, yes, equations and counting widgets...but it's more than that. Inside the simple act of accounting is a revolutionary way of thinking not just about a business, but about the world. A universe where all the forces are in balance. Accounting gives you a sixth sense–one that can help you determine whether your business will survive or fail.In this class, you'll learn the basics of accounting, and uncover its origins. We'll introduce you to the man who helped it spread around the world. He was a monk, a magician, and possibly the boyfriend of Leonardo da Vinci.Is accounting... sexy?Yes. Yes it is.Find all episodes of Planet Money Summer School here.This series is hosted by Robert Smith, and produced by Max Freedman. Our project manager is Julia Carney.

We here at Planet Money love economics papers. And that is also the case for so many of the economists we speak with. For them, new research can explain something they have always wondered about, or make them see something they have never noticed before. And it inspires their own work. So, to bring that same sense of discovery to you, the listener, today we are dedicating our show to a special experiment. A new way to share some of the most fascinating, clever and surprising economics papers in a segment we're calling: The Econ Paper Club.On today's show, we read the econ papers so you don't have to. We take a joyous romp through some of the most fascinating ideas floating around economics right now. And we find that some of those fascinating ideas are about some of the biggest things in life: the careers we choose, the expectations that come with parenting and what one eminent economist calls 'greedy jobs.'

For episode 2 of Planet Money Summer School, we are talking strategy. You have your million dollar business idea, and maybe some money in your pocket to get it up and running. But now you enter into a crowded market. You have to deal with competition. So, what can you do to make sure your product is a success? That was the conundrum facing the Starbury. It was a basketball shoe with a celebrity endorsement, that had to go up against THE basketball shoe with THE celebrity endorsement: the Air Jordan. Our first story is about the ways in which the Starbury succeeded and failed in taking on a juggernaut.Then, we will hear a story about trying to avoid the dangers of "perfect" competition. Two companies making almost identical handbells learn that the key to their success lies in convincing customers how different they really are.Find all episodes of Planet Money Summer School here.The series is hosted by Robert Smith and produced by Max Freedman.

When you make an account online or install an app, you are probably entering into a legally enforceable contract. Even if you never signed anything. These days, we enter into these contracts so often, it can feel like no big deal.But then there are the horror stories like Greg Selden's. He tried to sue AirBnB for racial discrimination while using their site. But he had basically signed away his ability to sue AirBnB when he made an account. That agreement was tucked away in a little red link, something most people might not even bother to click through. But, it wasn't always like this. On today's show, we go back in time to understand how the law of contracts got rewritten. And why today, you can accept a contract without even noticing it.

Find all episodes of Planet Money Summer School here.Planet Money Summer School is back! It's the free economics class you can take from anywhere... for everyone! For Season 4 of Summer School, we are taking you to business school. It's time to get your MBA, the easy way!In this first class: Everyone has a million dollar business idea (e.g., "Shazam but for movies"), but not everyone has what it takes to be an entrepreneur. We have two stories about founders who learned the hard way what goes into starting a small business, and getting it up and running.First, a story about Frederick Hutson, who learned about pain points and unique value propositions when he founded a company to help inmates and their families share photos. Then, we take a trip to Columbia, Maryland with chefs RaeShawn and LaShone Middleton. Their steamed crab delivery service taught them the challenges of "bootstrapping" to grow their business. And throughout the episode, Columbia Business School professor Angela Lee explains why entrepreneurship can be really difficult, but also incredibly rewarding, if you have the stomach for it.(And, we should say, we are open to investors for "Shazam but for movies." Just sayin'.)Help support Planet Money and get bonus episodes by subscribing to Planet Money+ in Apple Podcasts or at plus.npr.org/planetmoney.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

When it comes to big questions about the economy, we're still kind of in the dark ages. Why do some economies grow so much faster than others? How long is the next recession going to last? How do we stop inflation without wrecking the rest of the economy? These questions are the domain of macroeconomics. But even some macroeconomists themselves admit: While we have many theories about how the economy works, we have very few satisfying answers.Emi Nakamura wants to change all that. She's a superstar economist who is a pioneer in the field of "empirical macroeconomics." She finds clever ways of using data to untangle some of the oldest mysteries in macroeconomics, about the invisible hand, the consequences of government spending, and the inner workings of inflation.Recently we called her up to ask her why the economy is so difficult to understand in first place, and how she's trying to find answers anyway. She gets into all of that, and how Jeff Goldblum shaped her career as an economist, in this episode. This show was hosted by Jeff Guo and Nick Fountain. It was produced by Dave Blanchard with help from Sam Yellowhorse Kesler. It was engineered by Josephine Nyounai and fact checked by Sierra Juarez. Keith Romer edited the show.

Two stories today.First, as we start to understand post-affirmative action America, we look to a natural experiment 25 years ago, when California ended the practice in public universities. It reshaped the makeup of the universities almost instantly. We find out what happened in the decades that followed.Then, we ask, why does it cost so much for America to build big things, like subways. Compared to other wealthy nations, the costs of infrastructure projects in the U.S. are astronomical. We take a trip to one of the most expensive subway stations in the world to get to the bottom of why American transit is so expensive to build.This episode was hosted by Adrian Ma and Darian Woods.

The shocks of the pandemic economy gave us a bunch of enormous natural experiments, which helped to prove or disprove conventional economic thinking.Take, for example, the bullwhip effect, the idea that the further away from the customer you are in the supply chain, the more volatile your orders are likely to be. This theory played out at an enormous scale, in the pandemic. Consumers and companies overreacted to the risk of shortages by ordering more products and hoarding them, causing massive shifts in the supply chain – just like the theory says.And the pandemic gave us a lot of natural experiments like this. So, on this special live edition of Planet Money, we looked for other big economic lessons from the past three years, and we took this information and turned it into... a gameshow! It's Two Truths and a Lie: Econ Edition. We get into questions about the workforce and labor market during the pandemic, and how it affected how economists view the world.This episode was hosted by Mary Childs.
