In NYC and China, developers are building smaller apartments.

An iPad turns on the lights, the shower is a futuristic sounding vertical tube near the door and the bed becomes seating.  Occupying 161 square feet, this Dongguan, China micro-apartment is the size of a US mall parking space. But, at $133 a square foot (835 yuan), for a young Chinese software engineer, the price is right.

In NYC also, you might be able to buy a micro-apartment. While currently the minimum apartment square footage is 400, Mayor Bloomberg is suppporting a pilot project that downsizes units to 275 or 300 square feet. If the experiment works, he says zoning minimums might change.

What is the message?

In China, it is about the labor force. As workers move to cities and factory towns, an increasingly urban workforce needs affordable housing that is far better than the substandard dwellings currently available.

In the US, more of us are living alone. With a 51% marriage rate among the adult population, a typical woman marrying at 26.5 and the average male at 28.7, with elevated divorce rates and longevity creating more widows and widowers, we have more urban singles.

Smaller urban units have so many implications.

Harvard economist Ed Glaeser tells us that people who live in cities not only use up fewer resources but also, they create “spillover.” As we said in an earlier post, “A spillover is just the spread of something, such as a new idea, beyond the spot where it originated. When a new idea easily spreads because…people [live closer to each other in the city], we would say the spillover created a positive externality. That just means that an accomplishment that originally involved 2 entities, rippled outward to benefit many.”

Sources and Resources: Articles about micro-apartments are fascinating–especially the pictures. This Reuters report talks about NYC while WSJ focuses on China and here is what San Francisco is planning. For more about demographic trends in the US, you might want to see these Pew Research facts.

The fuel economy window sticker for this vehicle would say 1 gallon per 32 feet. Called the crawler, it travels on a roadway 3.5 miles long, could carry 18 million pounds, and moves no faster than 2 mph. The crawler takes the space shuttle to its launchpad.

With the last space shuttle scheduled for July 8, the crawler is at the end of its long life. However, the knowledge it generated will live onward. Similarly, technology targeted for the space program was spun off to private industry. Temper foam? Now in mattresses. Vibration analysis? Used in guitars. Space suit technology? Found in sneakers.

The Economic Lesson

As economists, the Crawler takes us to the spillovers and positive externalities of the space program.  With a spillover, others enjoy the benefits of a project originally involving a small group. Similarly, with a positive externality, a transaction between two individuals beneficially affects a third party. A vaccine for example, creates a positive externality. Yes, it benefits the person receiving it. But then, many others also remain healthy.

Originally involving 2 entities, NASA and its sub contractors, NASA technology will ripple outward to benefit many.

An Economic Question: From which positive externality might you benefit?

Uncertainty can slow economic growth.

Playing against Jeopardy champs Ken Jennings and Brad Rutter, Watson, the IBM computer won.

Imagine three podiums. One is labeled Ken, the middle one Watson, and the third one, Brad. IBM assured everyone that Watson had no internet access and all three players had to use their mechanical buzzers. Host Alex Trebek ran the game as he always had. Categories? For this round the contestants could choose from: Literary Character APB, Beatles Names, Olympic Oddities, Name the Decade, Final Frontiers, Alternate Meanings.

The game soon revealed Watson’s strengths:

Memory: Having “gobbled” up information from books, movie scripts, encyclopedias, dictionaries, countless sources, Watson knew it all and won’t forget anything.

Reaction time: Watson was fast. (And he was programmed to buzz only when he had the answer while the humans sometimes buzzed just before they thought of it.)

Decision-making: With wagering a part of the game, Watson had to decide what to bet. He had sufficient information about the facts and past games to know how much would be appropriate.

You might enjoy this TED talk about Watson.

The Economic Lesson

With countless business, medical, and consumer applications where Watson’s skills are valuable, “he” can affect all of us.  Physicians, for example, could consult Watson for speedy medical diagnoses that could include a “confidence” number indicating whether the statistics are convincing.

As economists, Watson takes us to spillovers and positive externalities.  Originally involving 2 entities, Watson’s impact will ripple outward to benefit many.

So really, everyone, not just Watson, has won.
