Competition in the Bathroom

For many years, a common graffito in men’s rooms was: “Wash hands, place hands under blow dryer, dry hands on pants.”  The old-fashioned low-powered dryers didn’t have enough power to dry hands well in any reasonable amount of time.  No more: about 10 years ago the Dyson Airblade was marketed, and it was revolutionary:  10 or 15 seconds and one’s hands really were dry.

I assume that they were expensive, which is why I only saw them in a few places, even in the U.K., where they originated. Today they are much more widespread.  They aren’t cheap (I see a discounted price of £615), but I bet they have come down in price.  Why?  The answer is competition: other companies are now making equally effective products, both in the U.S. and the U.K. An innovating entrepreneur may enjoy a monopoly for a while, but competitors with similar products will enter the market, forcing prices down (and increasing consumer surplus for now dry-handed users like me!).



Why Are Restroom Hand-Washing Signs By the Sinks?

All over America, restrooms for the public (for example, in restaurants or public parks) have signs warning and exhorting us that “Employees must wash hands before returning to work” or “Hand-washing stops the flu!” These are useful public-health messages. However, in almost every restroom I’ve been to, the sign stares at you from the mirror behind the sinks. What is the point of reminding the already hygiene-conscious to wash their hands?

But in the San Francisco airport a few days ago, I finally found a “Clean hands, good health!” sign at the restroom exit door. I don’t know whether it ever caused someone to U-turn and head for the sinks, but at least it isn’t carrying coals to Newcastle.

How to Get Doctors to Wash Their Hands, Visual Edition

In our latest podcast “What Do Hand-Washing and Financial Illiteracy Have in Common?,” we revisited a topic we wrote about a few years back: how one hospital (Cedars-Sinai Medical Center in Los Angeles) has tried to increase the rate of hand hygiene among its doctors. In the podcast, chief medical officer Michael Langberg regretfully reported that his doctors, like many doctors, routinely failed to wash their hands. Cedars-Sinai came up with a series of computer screensavers and posters that, along with some other creative measures, significantly jacked up the hand-hygiene rate. Read More »



What Do Hand-Washing and Financial Illiteracy Have in Common? A New Freakonomics Radio Podcast

Our latest podcast is called “What Do Hand-Washing and Financial Illiteracy Have in Common?” (You can download/subscribe at iTunes, get the RSS feed, listen live via the media player above, or read the transcript below.) It explores the idea that most problems are solved by more education — except when they’re not.

You’ll hear Michael Langberg, chief medical officer at Cedars Sinai Medical Center in Los Angeles, talk about why doctors there (and elsewhere) routinely fail to wash their hands despite the evidence suggesting they must:

LANGBERG: There’s something in the human condition that somehow disconnects what is really good evidence from personal choice and habit. And I don’t know why that is. I’m not a psychiatrist; my field is internal medicine. I just have the observation. Physicians are no different.

How to Open a Public-Restroom Door

Exiting a public restroom can be tricky. Touching a doorknob or push-plate means you take a chance of picking up a lot of terms. If you use a paper towel, you have to find someplace to throw it away. Read More »



Busting Docs Who Don’t Wash Their Hands

Here’s an interesting method of combating the hand-hygiene problem discussed at length in SuperFreakonomics: “A doctor enters a hospital room to examine a patient, but neglects to wash her hands. A special badge on her lab coat turns a deep shade of red as wireless computer components in the door, the soap dispenser and near the bed immediately relay information about the unwashed hands. The doctor is busted.” Read More »
