put a McDonald’s on every corner? Or was
New York Times columnist Thomas
Friedman closer to the mark when he called the protesters “a Noah’s ark of flat-
earth advocates, protectionist trade unions and yuppies looking for their 1960’s
fix”?

During the 2008
presidential primaries, Barack Obama criticized the North
American Free Trade Agreement, which was negotiated during the presidency of
fellow Democrat Bill Clinton. Were Obama’s comments good economics, or just
good politics (since he happened to be running against Bill Clinton’s wife)?
After Chapter 12, you can decide.
I offer only one promise in this book: There will be no graphs,
no charts, and
no equations. These tools have their place in economics. Indeed, mathematics
can offer a simple, even elegant way of representing the world—not unlike
telling someone that it is seventy-two degrees outside rather than having to
describe how warm or cool it feels. But at bottom, the most important ideas in
economics are intuitive. They derive their power from
bringing logic and rigor to
bear on everyday problems. Consider a thought exercise proposed by Glenn
Loury, a theoretical economist at Boston University: Suppose that ten job
applicants are vying for a single position. Nine of the job candidates are white
and one is black. The hiring company has an affirmative action policy stipulating
that when minority and nonminority candidates are of equal merit, the minority
candidate will be hired.
Further suppose that
there are two top candidates; one is white, the other is
black. True to policy, the firm hires the black candidate. Loury (who is black)
makes this subtle but simple point: Only one of the white candidates has suffered
from affirmative action; the other eight wouldn’t have gotten the job anyway.
