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.

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.’

This episode was hosted by Erika Beras and Kenny Malone. It was produced by Sam Yellowhorse Kesler and James Sneed. It was edited by Molly Messick. It was fact-checked by Sierra Juarez, and engineered by Robert Rodriguez. Alex Goldmark is our executive producer.

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.

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.

This episode was hosted by Emma Peaslee and Jeff Guo, and was produced by James Sneed. It was edited by Jess Jiang and fact-checked by Sierra Juarez. It was engineered by James Willetts. Alex Goldmark is our Executive Producer.

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’.)
