The Economics of Fantasyland
William J. Bennetta
California sits on a shelf of land that will break off and fall into
the sea during the next earthquake. Residents of New York City buy
baby alligators for pets, tire of them, and flush them into the city's
sewer system, where the 'gators grow into big, dangerous beasts. The
world has enough food for everyone, but people starve because the food
isn't distributed properly.
All of those notions are silly, of course, but they are widely
circulated and widely believed. The fantasy about abundant food is
particularly interesting. In this age of ecological collapse, we
might expect the plenty-for-everyone story to fade away because its
falsity is so manifest. It keeps showing up, however, and it even
appears in the 1993 version of ChemCom. Read page 223:
Three factors determine the abundance or scarcity of
any resource, . . . .
Supply (How much is available?)
Demand (How much is needed?)
Distribution (Where is it and how can it be
obtained?)
According to the best available data, the world has enough food for
everyone. The World Hunger Project at Brown University estimates that
sufficient food is produced globally to feed 20% more than the world's
current population. In other words, the overall supply of food
appears adequate to meet demands. [A note in the page-margin
adds: This estimate assumes an adequate vegetarian diet.]
Why then is there world hunger? . . . The distribution of
food must certainly be one key to the puzzle (Figure 1). [In
figure 1, unlabeled arrows fly among "Supply" and "Distribution" and
"Demand."]
That entire ChemCom excursion, including the citing of the
"World Hunger Project," is rubbish. It contains no valid information
at all, and it involves a brazen distortion.
The ACS writers begin by giving utterly nonsensical definitions of
supply, demand and distribution, and by depicting supply
and demand as mystical things that are fixed and independent of each
other. Let me correct the writers' misconceptions:
Supply No matter how the word
supply may be used in common speech, its meaning in economics
is precise: The supply of a commodity is the amount that producers
are willing to send to market at a specified price. The ACS
writers' claim -- that "supply" is merely the amount that is
"available" -- is meaningless, since the available amount rises and
falls with price. A higher price induces greater production (i.e., a
bigger supply), a lower price does the opposite, and these effects
occur continually.
Demand Again, vulgar usage doesn't
matter. In an economic context, the demand for a commodity is the
amount that buyers are willing to take at a specified price. A
higher price repels some buyers, so demand falls; a lower price does
the opposite. Yet the ACS writers treat demand as a sort of physical
constant, and they make things hopeless by describing demand as how
much is "needed." What does that mean? The word need has no
established, reliable meaning in economics. We may read some ad
hoc meaning into it in a specific case, but it cannot serve in
defining basic economic quantities.
Distribution Distribution can be
defined as the task of getting a product to market and into the hands
of buyers. It entails some costs, of course, and these are reflected
in the market price; hence supply and demand automatically take
account of distribution. The ACS writers, however, depict
distribution as a basic economic force that ranks with supply and
demand but is separate from them. Wrong.
Far worse than the bogus definitions is the writers' claim that "the
best available data" show that there is "enough food for everyone."
Appalled to find that codswallop in a schoolbook, I sought to learn
where it had come from.
Rebecca J. Mason Simmons, a staff associate in the ACS's Office of
High School Chemistry, told me that the claim was based on The
Hunger Report: 1988 and The Hunger Report: Update 1989,
issued by The Alan Shawn Feinstein World Hunger Program (not
"Project") at Brown University. I obtained those documents, and I
found that the text about global food resources was virtually the
same in both. Here is the version given on page 2 of the
Update, under the heading "Global Food Shortage":
Drawing upon the most recent estimates of primary food
supply, the world's vegetative food supply and the products of
range-fed animals would provide an adequate diet for some six billion
people or 20% more than the current population of the world . . . .
Indeed, by this standard there has probably been enough food to feed
the world's population since the early 1960s.
But given a modest improvement beyond what is essentially a
near-vegetarian diet to one similar to what many South Americans eat today,
a real food shortage exists in the world. For at that standard, there
is only food enough to feed about four billion, or 80% of the
current world population. And to provide a full-but-healthy diet, one
that incorporates the desires most people have for richer and more
varied foods, then there is only sufficient food in the world to feed
about three billion people or 60% of the world population. Of course,
it is important to note that much more food probably could and would
be produced if more people had the means to purchase
it.
As the last sentence of that passage makes clear, the writers of the
Update know that supply and demand are related to each other,
are variable, and are linked to price. (The ACS writers have managed
to exclude all of those points from their Fantasyland economics.) The
Update writers also tell (on their page 3) that they are
analyzing information for the year 1986. Such information is now
obsolete, but the ACS writers grandly call it "the best available
data."
The most reprehensible aspect of the ACS writers' stunt, however, is
their brazen misrepresentation of the results that the Update
sets out. The Update writers considered three standards of
diet. Using the first standard, which obviously did not reflect the
real world of 1986, they calculated that food in 1986 was
superabundant; but with the other standards they found that food
stocks in 1986 were inadequate by wide margins. The ACS writers have
used the first case to promote the plenty-for-everybody fantasy while
suppressing the other cases completely.
