請依下文回答第 46 題至第 50 題: As the concept of human rights is based on fairness, the exposure of so many people in poor countries to hazardous
industrial processes and toxic wastes violates their rights. This is the view of many experts. In 1994, a group of experts
met in Geneva to compose a more general document: “Draft Declaration of Principles on Human Rights and the
Environment.” It proclaims, among other things, a universal human right to a “secure, healthy, ecologically sound
environment.”
But many economists give priority to economic growth because it leads to generally higher salaries and more
spending power for average individuals. Market exchanges generally promote economic growth, except where public
goods are concerned. In those cases, economists use cost-benefit analysis (CBA) to identify new rules of market
exchange that maximize growth.
We note problems with this approach. Economic growth does not improve human welfare if it merely reflects higher
prices and longer working hours stemming from the increasing scarcity of essential items, such as land to grow crops.
When governments use CBA, they give equal consideration to each dollar rather than to each person. This goes against
the ideal of equal government concern for all citizens. Also, CBA discounts the lives of future generation, as if people
living later have few human rights than those living now.
CBAs put all variables in dollar terms so that optimal policies can be identified mathematically. Shadow prices are
assigned to whatever is not traded in markets, including human lives. Economists estimate how much people value
their lives in monetary terms from how much they spend on life insurance and medical care, as well as how much extra
pay they demand for dangerous work. Also, when people are killed in accidents caused by negligence, jury awards
suggest common estimates of a life’s monetary worth. The problem is that on such measures an average human life in a
poor country is worth much less money than an American, European, or Japanese life. This denies an equal human
right to life.
【題組】48 According to the passage, what might be the problem of using CBA to estimate a life’s monetary worth?
(A)It will call attention to the valuable lives of future generation.
(B)It fails to reflect the higher prices of certain valuables.
(C)It leads to correct measurements of human life.
(D)It will notice the essential items in life.
