I always enjoy a good laugh bit it rarely happens when I am
reading economics. I’ve never thought of
economics as the “dismal science” but likewise, it never seems to be a barrel
of laughs. Two weeks ago, while reading
one of the Sunday newspapers, I came across an interview by Mary Ann Gwinn of
The Seattle Times with Yoram Bauman, Ph.D. who describes himself as “the
world’s first and only stand-up economist.” In addition to a Ph.D., according
to the interview, Yoram has a background doing “stand-up routines at Seattle’s
Comedy Underground. The interview also
mentioned that Yoram is the co-author of the recently published “The Cartoon
Introduction to Economics: Volume Two: Macroeconomics,” which I immediately ordered
after reading the interview.
The book is fun to read and funny as well. More importantly the economics is solid and
the book does a good job explaining important economic concepts in common sense
ways with very helpful illustrations by the co-author and cartoonist Grady
Klein. For example, in the discussion on
inflation, and specifically how prices change in real as opposed to nominal
terms, the discussion goes as follows:
To avoid
suffering from money illusion, economists study how prices change in real
terms.
Real prices are adjusted for inflation. They
show us how the price of something has changed
relative to the overall price level.
For example compare the price of
milk in 1920.
That’ll
be $0.72 per gallon.
With the price in 2010.
That’ll be $3.00 per gallon.
Based on this
comparison of nominal prices, it
looks as if milk has gotten a lot more expensive.
$3.00 per gallon!? When I was a kid,
milk was only $0.72 per gallon!
But if we adjust for inflation between 1920 and 2010
In
1920 milk was $0.72 per gallon. But the CPI says that average prices in
2010 were
10
times higher … …So in today’s dollars the price of milk was
about $7.20
per gallon!
...we see that the real price of milk has actually fallen.
What this means
is that the prices of most other things have gone up more than the price
of milk.
The discussion of GDP is another example of a good
discussion of economic principles accompanied by helpful yet funny cartoons
However you
measure it, GDP gives
macroeconomists a way to tell a story
about the entire economy.
Mommy tell me a
story. $5.8 trillion… $8.4 trillion…$10.2 trillion…
GDP sheds light
on everything from Health Care…
Health
care spending in 2008 was only 8% of GDP
in Finland... …but was 16% of GDP
in the United States… … and it’s growing fast everywhere.
…to the size of government
Federal, state and
local governments in the U.S. make up about 35% of GDP.
…to the National Debt
During World War II,
the U.S. national Debt soared to over
100% of GDP.
Then it was pretty
steady at 30-60% of GDP for fifty
years. And after the 2008 financial crisis, it’s heading back up toward 100%.
No wonder GDP is the most important statistic in macroeconomics!
I have left out the cartoons from my review of this book on
purpose. The text clearly and simply provides the key economic concepts that
define macroeconomics. It comes together as a superior overview. The cartoons
interject the lightness and humor. And
not surprisingly even critical economic concepts benefit from humor, and likely
the learning process is the greatest winner of all with a book like this. Congratulations to Klein and Bauman on a job
well done. We need more books like this.
