I purchased this book for personal use.

Everything I Ever Needed to Know About Economics I Learned from Online Dating, written by Paul Oyer and published by Harvard Business Review Press, takes a friendly approach to teaching basic economic concepts. The book covers topics including search, signalling, selection, and network externalities, in an approachable and personal manner. Oyer tells the tale through his own experiences in online dating. As someone who met his wife through online dating, I found myself rooting for the balding economist trying to find love while going through an unhurried divorce.

Light-Hearted, but not Lightweight

Paul Oyer is a professor of economics at the Stanford graduate school of business, so he is used to explaining economics to graduate students. It’s not a simple undertaking to translate that knowledge into terms that can be understood by the general reader. Yes, I understand that anyone who would purchase a book published by Harvard Business Review Press is probably not your average reader, but the book’s title and in the author’s writing style make it clear that this is not a weighty academic tome. If you want one of those, see if you can find a copy of The Economics of Electronic Commerce by Choi, Stahl, and Whinston, which I reviewed on this site in 1998.

Online dating is an interesting process. You go to a site such as Match.com or OkCupid, fill out a profile or answer questions, and let the computer code running in the background show you who it thinks you might be compatible with. It’s a combination of many economic activities: advertising, search, signaling, and network effects among many others. And, just as economics is often called the “dismal science”, online dating can take on an air of despair when you’ve been at it for a while but haven’t found anyone to spend time with.

Of course, some of this frustration can be self-inflicted. On page 12, the author cites an online dating profile published by a graduate student in China:

Never married; master’s degree or more; not from Wuhan; no rural ID card; no only children; no smokers; no alcoholics; no gamblers; taller than 172 cm; more than a year of dating before marriage; sporty; parents are still together; annual salary over 50,000 yuan; between 26 and 32 years of age; willing to guarantee eating for dinners at home per week; at least two ex-girlfriends, but no more than four; no Virgos; no Capricorns.

I hate to say it, but I think the guy she’s looking for is already married.

Economics and the Online World

I’d imagine that most of my readers will be familiar with at least some of the economic concepts that Oyer discusses in this book. That said, even though I have spent quite a bit of time with the popular literature discussing the economics of online commerce, I learned a few things from reading his book and was reminded of quite a few more concepts that I hadn’t encountered for a while. I also like that the author summarizes the economic concepts that he discussed in each chapter with a series of takeaways at the end. He lists a key insight from economics, a valuable or important empirical finding by economists, how dating compares to the concept discussed in the chapter, and a bit of humorous dating advice that puts a button on the chapter. In the chapter on signaling, for example, he gives this dating advice: “If you want to prove you are rich, burn a big pile of money on the first date.”

I enjoyed the author’s take on economics through the lens of online dating. He writes in a familiar, personal style, and ties the economic concepts he wants to explain into his personal narrative seamlessly. I’m just guessing, but I bet his first draft was pretty good. His editor, Tim Sullivan, certainly helped bring the manuscript together into an enjoyable, coherent whole.

Conclusions

I recommend Everything I Ever Needed to Know About Economics I Learned from Online Dating to anyone who is interested in contemporary economics, either as a casual reader just digging into the subject or as a more experienced hand who would enjoy a good-natured review.

Spend a Five or Break a Twenty? The Denomination Effect

leave a comment »

I’m sure many of us understand the denomination effect on a visceral level. If you’ve ever been in a store, saw something you wanted, but hesitated to buy it because you’d have to pull out a big bill, you’ve experienced this effect. Why did you hesitate? Because you knew that breaking that $20, $50 or $100 bill made it that much easier to spend your change.

Perhaps that’s why prices near a dollar amount, particularly $4.99, $9.99, $19.99, and $99.99 are so attractive to the consumer’s eye. You’re trading one physical item (a printed piece of paper) for another (perhaps a flash drive) and getting a tiny bit of money back. I wonder how much of the attractiveness of prices just below a currency denomination depends on the fact that you’re getting some change back as opposed to the first number being one less (e.g., $19.99 versus $20.00). I bet the two phenomena are intertwined in some interesting psychological ways.

You also see the denomination effect at work in gambling, but the effect works differently there depending on the game and situation. Knowledgeable poker players experience the reverse effect, becoming less likely to get involved in hands when they have fewer chips in their stack. They hesitate to invest in a hand because, when you are low on funds, the relative value of each chip goes up. Other players can use this hesitancy to their advantage and bet big to drive the small stacks out of a pot, but the small stacks can make a modest bet to induce a bluff raise from a big stack, but the big stacks can raise and hope the small stacks will think they’ve fallen into their trap, but…

You get the idea. Poker’s fun, but bring aspirin.
