A more revealing
measure of taxable income counters the long-held belief that tax
hikes for the rich will shrink, rather than boost, tax revenue,
says Austan Goolsbee, a GSB assistant professor. In a study
for the National Bureau of Economic Research, he shows that a slight
dip in the taxable income of some 10,000 top executives primarily
resulted from their exercise of stock options, not the 1993 tax
hike. Previous studies ignored the flexibility of the execs' income.
punch against cancer
naturally produced chemical that inhibits the formation of new blood
vessels-with radiation therapy enhances the anti-cancer effects
of each, reports a multi-university team of medical researchers
in the July 16 issue of Nature. Led by Ralph Weichselbaum,
the chair of the U of C's department of radiation and cellular oncology,
the team's discovery could aid in the fight against tumors by providing
more local control of cancers.
A recent study
by Harris School dean Robert Michael may explain why Americans
have a higher rate of sexually transmitted diseases than Britons.
Based on surveys of 23,000 individuals, aged 16 to 59, from both
countries, Michael found that Americans tend to be more promiscuous
but less open about sex and less apt to practice safe sex. His conclusion:
"Our public health may be the high price we pay for our public opinion."

reign in cyberspace? Not according to Jack Goldsmith, a Law
School associate professor. Goldsmith argues in an upcoming U of
C Law Review article that regulation of cyberspace should follow
the standards applied to the telephone, the mail, and other communications
media. If an activity is illegal off the Net, he contends, it should
be illegal on the Net as well.-M.B.
