Asked by the Pew Center for the People and the Press to rank 21 issues in terms of their significance, global warming was #21. Similarly pessimistic about climate change initiatives, one researcher asked, “How can one seriously suggest that the village kid in India should give up her hopes of prosperity, education, and health care today, in order to prevent rising ocean levels many years down the road?”

What can an environmentalist do?

Maybe… connect current economic benefit to future climate results. Then, the iron law of climate policy is no longer an obstacle.

Described in the NY Times, a recent Science article suggests 14 policies that would have a beneficial economic impact now and also diminish the future global warming that the paper’s authors predict. One proposal would involve farmers in developing nations draining rice paddies more frequently to increase their yield while simultaneously reducing methane emissions.

Described in “Climate Pragmatism,” climate and health care concerns converged in a 2009 Congressional proposal for reducing black carbon soot. Two of the bill’s sponsors were environmentalists while a third sponsor questioned climate change but wanted the health benefits of cleaner air. 

The Economic Lesson

Edwin Mansfield, a University of Pennsylvania economist (1930-1967) who studied the impact of innovation concluded that smaller innovations such as new industrial thread had a much greater social rate of return than products and processes that sound more dramatic. Recent suggestions to mitigate global warming also imply that “less is more.”

An Economic Question: How might rice paddy drainage be comparable to the smaller innovations that Dr. Manfield said were so effective?

This apple has bites rather than bytes but like its namesake it was patented and took years to develop. When its U.S. patent expired in 2008, it had generated close to $6 million for the University of Minnesota and is still producing royalties in Europe.  With Google, the nicotine patch and the V-chip, it was even named one of 25 innovations that transformed the world.

The name of this apple? The Honeycrisp.

And now, the Honeycrisp has become a mother. You might enjoy reading about its offspring, the SweeTango in this PBS report and a New Yorker video and article by John Seabrook.

The Economic Lesson

Just like a new drug or chemical process, an apple undergoes R & D, gets intellectual property protection, generates royalties, and creates competition and knock-off concerns when its patent expires.

Having taken 31 years to develop, the Honeycrisp’s royalty revenue stream is divided among its inventors, a fund for further research, and the department/college where the faculty developers worked.

An Economic Question: Citing the Honeycrisp, explain why you agree or disagree with Edwin Mansfield (1930-1997) a University of Pennsylvania economist who said that seemingly small innovations can have a massive impact.

The kitchen that my mother used 50 years ago is really not that different from the one we use today. Electricity, a mechanical refrigerator, and hot and cold running water have been here for a long time. But 60 years before that, the kitchen was a very different place.

According to Princeton’s Stanley Lebergott (1918-2009), in Pursuing Happiness, in 1890, 24% (the majority in cities) of all homes had running water. In 1900, no one had a mechanical refrigerator and only 3% of all U.S. kitchens had iceboxes and horse drawn wagon deliveries of ice blocks. A freezer? No.

Looking at those two kitchens, economist Tyler Cowen expresses concern. He relates the lack of meaningful technological change in the home to a stagnant standard of living and ineffectually rising health care and education spending.

The bottom line? Nationally, we have to live within our means until the next technological revolution.

The Economic Lesson

What kind of technological revolution is meaningful? Sometimes less is more. Research from Edwin Mansfield (1930-1997) indicates something as simple as a new kind of industrial thread can make a big difference.

It is tough to design a vending machine that will handle a banana gently. The temperature needs to be 57 degrees, a 4 foot fall to the consumer should be gentle, and they have to remain ripe for as long as possible. It gets even trickier when celery, which requires 34 degrees, is nearby. (It must have been even more difficult to make this vending machine for live crabs.)

The first Post-It Note also was a developmental challenge. The problem was the adhesive. But when Art Fry, in new product development at 3M, heard about a temporary adhesive, the “sticky” was born.

 

The Economic Lesson

The private rate of return–the net amount a business gets from an investment–tends to vary considerably and can ultimately be nonexistent because of competition. Moving beyond its origin, as the impact of the innovation ripples through society positively and negatively, it creates a social return. Both are tough to calculate. Edwin Mansfield, a University of Pennsylvania economist (1930-1967) who studied the impact of innovation concluded that smaller innovations such as new industrial thread had a much greater social rate of return than products and processes that sound more dramatic.

Maybe the banana vending machine will have more of an impact than we suspect?

What is 68 feet long, has a giant blade in front for plowing, massive sweeper brushes in the middle, and a 452 MPH wind blowing capacity in the rear?

A Vammas.

Imported from Finland, the Vammas is used by Logan Airport for snow removal. A caravan of ten Vammas can clear a snow covered runway in as little as ten minutes (depending on the snow).

Wearing your economic lenses, you could see that the Vammas generates a private and a social return. The positive social return of snow removal is considerable. However, is there also a negative side?
