The Wealth of Nature

A three-part series profiling ecological economists

by Lissa Harris

08 Apr 2003

In 1776, the year the Scottish economist Adam Smith invented 
free-market economics with his book The Wealth of Nations, the total 
population of the globe was less than 700 million people. The 
coal-hauling locomotives and steamships that were to drive the 
Industrial Revolution were still 30 years off. Free-market economic 
theory grew and flourished in an era of abundant natural resources, 
in which the commodities that were the most rare -- and thus the most 
precious -- were the products of human technology. Nature was so 
bountiful that economists could afford to leave her out of their 
calculations.

Fast-forward to 2003. The world's population has increased nearly 
tenfold. We are awash in technology, but our natural resources are 
rapidly dwindling. No longer can we rely on the infinite bounty of 
nature to provide healthy soil, clean air, and potable water. Yet 
even as the value of the environment to society becomes more and more 
apparent, so also does the inability of markets to recognize that 
value.

And it's easy to see why. Compared to pork bellies and Palm Pilots, 
most goods and services provided by the environment are peculiar and 
ill-behaved: They don't respect property rights, they may take 
millennia to turn a profit, they benefit those who pay for them and 
those who don't alike. Neoclassical economists -- the intellectual 
scions of Adam Smith -- have generally been content to treat the 
environment as a particularly vexing sector of the overall economy, 
developing a group of theories collectively known as environmental 
economics to sort out the thorny problems presented by goods that 
don't fit the market mold.

But recently, a group of mavericks known as "ecological economists" 
have begun to hammer out a new paradigm that stands economic theory 
on its head. Rather than the environment being a subset of the 
economy, they argue, the market is a subset of the global 
environment, and all the goods and services we trade ultimately 
depend on natural resources and processes. Ecological economists, 
while still personae non gratae in most university economics 
departments and major economic policy-setting institutions, are 
slowly gaining in influence, both in academia and among the general 
public.

In a special series, we profile three practitioners of the new science:

* Robert Costanza, director of the Gund Institute for Ecological 
Economics and the man who became famous for putting a price tag on 
the biosphere. In 1997, Costanza was lead author of a paper that 
declared the value of the services provided by the world's ecosystems 
to be almost twice that of the combined GNPs of all the nations of 
the world. The study made international news, prompting headlines 
like "How Much is Nature Worth? For You, $33 Trillion."

* Joshua Farley, a researcher at the Gund Institute for Ecological 
Economics, and a staunch crusader for the new paradigm. In 1996, 
Farley prized a doctorate in economics from the clutches of a 
committee of old-guard economists. Now he is making it his mission to 
literally rewrite the book for the next generation, coauthoring (with 
Herman Daly) the first textbook in ecological economics.

* Herman Daly, the founding father and reigning guru of ecological 
economics. A former insider at the World Bank who is now one of its 
sharpest critics, Daly is the co-founder of the journal Ecological 
Economics and author of over 100 books and articles, including 
Steady-State Economics and Beyond Growth.
