    Why Was Malthus a Reverend?

    Nov 1 • Economic History, Economic Thinkers, Innovation • 400 Views

    Have you ever wondered why Malthus was a reverend?

    The surprising answer is in Bill Bryson’s wonderful new book, At Home A Short History of Private Life (which I just started reading). 18th and 19th century rectors and vicars tended to be affluent and bored. As Bryson explains, rather generous rents and tithes, during good times and bad, funded their pay. Their preparation typically was a university degree in any area. With little training in human sustenance and a book of sermons to refer to each week, they had considerable time on their hands.

    What to do? The Reverend Malthus thought and wrote about economics and the future of the world. Other clergy with similar inclinations include Edmund Cartwright, the inventor of the power loom; George Garrett, who invented the submarine; William Buckland, an expert on fossilized feces; and Jack Russell, a terrier breeder. (The Jack Russell terrier is today’s picture.)

    The Economic Lesson

    Perhaps one of the first environmentalists, Reverend Thomas Malthus told us in 1798 that population grows geometrically while resource production expands arithmetically. Consequently, resource prices will rise and supply will become increasingly inadequate.

    Silver Job Fairs

    Oct 31 • Developing Economies, Economic Debates, Government • 338 Views

    It is more likely that a 75 year-old South Korean will be working than a 60 year old Frenchman. According to OECD (Organization of Economic Cooperation and development) statistics cited by Floyd Norris, workers in South Korea and Japan remain in the labor force longer than their French counterparts.

    Is this good or bad? It might depend on how you answer the following questions:

    1. Is grandpa taking junior’s job?

    2. Can government afford to take care of grandpa?

    3. Does grandpa like his job?

    The Economic Lesson

    While France is hit by demonstrations against raising the retirement age to 62, South Korea is scheduling “silver job fairs” to help older workers find jobs. Understanding the different approaches takes us to the political, economic, and social implications of fiscal policy–government spending, taxing, and borrowing.

    Banana Machines

    Oct 30 • Businesses, Economic Thinkers, Innovation • 385 Views

    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?

    Mankiw and Colbert

    Oct 29 • Demand, Supply, and Markets, Government • 364 Views

    For some smiles and econ also, the following links are fun.

    It all began with Harvard’s N. Gregory Mankiw’s NY Times op-ed column on higher tax rates. Explaining, he said that $1000 wisely invested, with no taxes, became $10,000 in 30 years. By contrast, letting the Bush tax cuts expire slices that $1000 to a $523 check which other taxes further deplete. The result? In 30 years, the amount grows to $1700. Knowing that he would have considerably less to save for his children could result, he said, in writing fewer columns.

    Stephen Colbert responded to Mankiw here. And, after that, Mankiw’s students replied to Colbert.

    Smiling at the exchange, we can also consider the debate about tax rates and see how Dr. Mankiw’s students used demand and supply to present the impact of Colbert on their teacher.

    The Economic Lesson

    In Teaching Company Lecture 3, from “History of the U.S. Economy in the 20th Century,” Professor Timothy Taylor describes a roller coaster of tax rates. Starting from a top 77% rate after World World I, rates then descended more than 40%. Taylor tells us that while tax rates fluctuated considerably, tax revenue remained remarkably constant then and at other times during the 20th century.

    Dogs, Coach, and Cars

    Oct 28 • Demand, Supply, and Markets, Households, Innovation, Macroeconomic Measurement • 382 Views

    When you have extra income, what do you buy? In China, the more affluent consumer is buying dogs, Coach handbags, and cars.

    Banned in Beijing in 1983, only recently, the dog has returned as a new “best friend.” A stress reliever, a response to “one child,” and a status symbol, dog ownership in Beijing totals 900,000 and is rising. Correspondingly, dog treats, dog care, and pet parks all have growing sales.

    China’s middle class also is buying Coach handbags and cars. In its recent conference call, Coach said it is opening 4 new stores for a total of 49 in China. GM also identifies China as a source of sales growth.

    The Economic Lesson

    In the US, the consumer started to play a major role in the US economy during the 1920s. Buying cars, radios, and refrigerators for the first time, the consumer propelled economic growth.

    With their potentially gargantuan numbers, might a growing Chinese middle class stimulate growth at home and in the US?
