I suppose it is a little early for news stories that
characterize the dog days of summer but a recent CBC item on Prairie Dogs
certainly caught my attention.
Prairie dogs are social animals that live in cooperative groups and
apparently they have relatively sophisticated language. According to the story, via their
chirps they are able to describe the color of clothing being worn by human
visitors as well as whether or not they are carrying a gun. All of this fits into recent work on
whether animals are sentient that is revising our actual and perceived relationships
with the animal world. My next
question: are animals characterized by economic behaviour?
Well, there is apparently a literature here also and the
discussion has appeared previously on WCI courtesy of Frances. Animals have to make decisions about resources too and can
be trained to make choices. European
Starlings can make rational decisions.
An experiment (Schuck-Paim,Pompilo & Kacelnik (2004)) was conducted
in which European Starlings were trained to choose between two rich food
sources and one poorer decoy one.
The two rich food sources were differentiated by the amount of
time/pecking required to receive the food. The poorer decoy offered much smaller amounts for the amount
of effort relative to the richer food sources. According to the study, the animals were sometimes
“irrational” in preferring the decoy but the choice seemed to be a function of
how hungry the birds were–their energetic state. The authors suggest it may be possible that animal
preferences are such they are less motivated to focus exclusively on the
richest food source when well fed.
Does this mean that once animals are well fed they get bored and like to
experiment? That seems almost
like a human hierarchy of needs.
There seems to be quite a literature out there on animal
economic behaviour but not necessarily being written by economists. I came across a post in Psychology
Today on whether monkeys understand money and trade and how they are rational
in that when engaged in trading games they leave with more than they entered. Moreover, they do not appear to be very sensitive about issues of fairness. Capuchin monkeys apparently make
rational economic decisions in many of the same settings that humans do but
also make similar mistakes. For
example: “capuchins were asked to choose between spending a token on one
visible piece of food that half the time gave a return of two pieces, or two
pieces of visible food, that half the time gave a return of only one piece.
Economic theory predicts that consumers should not care which of these outcomes
they receive since they are essentially both 50–50 shots at one or two pieces
of food. The capuchins, however, vastly preferred the first gamble, which is
essentially a half chance at a bonus, than the second gamble, which is
essentially a half chance at a loss.”
Of course, it does start one wondering if animal economic
behavior is also a function of their “social and economic” environments. Prairie Dogs, for example are social
and live in communities. Do you
have some type of concept of cooperative behavior and public good provision
when it comes to building their burrows and tunnels and mounting a watch
against predators? Are there
business cycles in these communities triggered by fluctuations in weather and
food supply that affect community behavior? Do some animals care more for the welfare of their community
members than others? Monkeys
apparently are not as concerned about fairness. How about Prairie Dogs? Aside from giving a whole new dimension to the Keynesian term
“animal spirits” are these questions worth pondering in terms of the light they
might shed on the human experience? I suppose we will have to wait until the universal translation device mentioned in the CBC article becomes available to have a discussion with our animal kingdom colleagues.

“All of this fits into recent work on whether animals are sentient…”
Wow. Perhaps next some scientists will start “work” on whether bears defecate in the woods.
