The British economics Lionel Robbins defined economics as "the study of
the use of scarce resources which have alternative uses." It's a
pretty simple concept -- if the cost of filling up one's gas tank
increases from $40 to $80, then one has $40 fewer to spend on, say,
that new pair of Nikes or tickets to the Astros game. In the general
economy, the concept can become more complex, particularly when
government and politics get involved. Additional taxes paid by
businesses reduce the pool of money available for employee bonuses,
capital investments, or additional employees. Land used for planting
corn subsidized for ethanol production is then not available to grow
wheat or beans or other crops.
Politicians rarely look towards greater efficiency in promoting policies; rather, typically the
opposite
is the goal of government initiatives, as few laws are typically
required to coerce people to do what's in their own best interest, and
in the abstract of a free market competition promotes greater
efficiency. I'm not likely to use my scarce resource of time on what
is for me a highly inefficient task of working on my car; better
instead for me to pay the mechanic to do so, while I use my time to
work at something at which I am myself more efficiently deployed.
Few
places are economics as defined by Robbins ignored more than in
government action in health care and the environment. As demonstrated
by the recent debate over "cap and trade" legislation in the US Senate,
politicians often are willing to commit much of the scarce resource of
our paychecks to projects of undefined and even dubious merit. Some
estimates of the cost of the Warner-Lieberman legislation entered the
trillions of dollars; yet no mention of the alternative use of these
resources was discussed, and as mentioned above the benefit was nowhere
defined. The question remained: what benefit would cap-and-trade
bring, and at what cost? Is cap-and-trade the most efficient use of
our scarce resources, even if one accepts at face value the premise
that global warming is in fact a man-made problem for which there is a
legislative solution? Are there other problems even more pressing than
global warming that are more urgent, or even some "low hanging fruit"
-- problems that could be easily solved for a great number of people at
a minimal cost?
A group of esteemed economists, including five
Nobel Prize laureates, convened in a project called the Copenhagen
Consensus. Their task was to examine the state of the art in terms of
research and capabilities to solve global problems in the following
areas: air pollution, conflict, disease, global warming, hunger and
malnutrition, lack of education, gender inequity, lack of water and
sanitation, terrorism, and trade barriers. This group is no "industry
hack", nor "in the pocket of Big Oil" -- one of the lead researchers
was also a lead author on the report of the
Intergovernmental Panel on Climate Change -- the group that shared last year's
Nobel Peace Prize with former vice president Al Gore.
The
group's findings were interesting, to say the least. They found that
"spending $800 billion over 100 years solely on mitigating emissions
would reduce inevitable temperature increases by just 0.4 degrees
Fahrenheit by the end of this century. Even accounting for the key
environmental damage from warming, we would lose money, with avoided
damage of just $685 billion for our $800 billion investment." This
hardly seems an efficient use of scarce resources.
The
panel didn't advocate ignoring the effects of global warming; rather
than cutting emissions by decree, however, in the manner of government
command-and-control methods such as cap-and-trade, the panel instead
advocated a dramatic increase in the research and development of
alternative energy technologies such as solar panels.
Perhaps
most interesting, however, was that even this consensus choice towards
fighting global warming didn't crack the Top 10 list of the most
cost-effective ways of helping the world's poor. Unfortunately, the
list of actual cost-effective impact actions as determined by the
Copenhagen Consensus aren't flashy, and aren't likely to be front-page
headlines. Number 1? Vitamin A and zinc supplements. Number 3? Iron
supplements and salt ionization.
Perhaps most surprising was the
Number 2 action. Far from a government program, rather it is also an
option that increases individual liberty: increased free trade. Yes,
free trade is good for the poor, and good for the environment,
regardless of the protectionist hostility aimed at it by people like
Barack Obama, Lou Dobbs, and Pat Buchanan. As Bjorn Lomborg, the
political scientist who heads the project, states: "It's true that
trade doesn't immediately save lives, but it's proven that when people
have more money they improve their health,
their education and so on." And people tend to have more money when
they pay less for goods and services (as happens when tariffs are
lifted on imports) and when they have increased markets for the goods
and services they produce (as happens when import tariffs are reduced
in other countries).
When politicians are spending money, they aren't spending their own money but rather they are spending
ours.
The incentive is not efficiency, but rather the appearance of "doing
something". With global warming hysteria on the front page nearly
every day, being seen as engaged in the "fight" against global warming
is perceived as a good way to appear strong and visionary. Instead, a
truly visionary group of economists is showing us that there are better ways to allocate our scarce resources.
If
truly helping people is the goal, rather than self-serving,
short-sighted, political expediency, our politicians would be
well-served to read the recommendations of the Copenhagen Consensus.
