●
“The study of the individual parts of the economy,
the household and the firm, how prices are
determined and how prices determine the
production, distribution and use of goods and
services.”

Also known as price theory

Headlines: Productivity Grew at Fastest
Rate Since 1983
Companies' output surged at a 10.3 percent annual rate in the period, the biggest increase
since the third quarter of 1983, a pace that was even better than the previous estimate of
8.8 percent.
Meanwhile, workers' hours increased at a 0.8 percent rate in the quarter, the best showing
since the first quarter of 2000.
And unit labor costs fell at a 5.8 percent rate in the quarter.
The combination of rising output and lower costs is a big reason why corporate profits
were as strong as they were in the third quarter, economists said.
"Businesses were able to increase margins and hold prices down," said Sung Won Sohn,
chief economist at Wells Fargo Bank. "This is very good news for the economy as well
as corporate profits. But employers have probably squeezed as much as they can out of
this orange."

“Speculators may do no harm as bubbles
on a steady stream of enterprise. But the
position is serious when enterprise
becomes the bubble on a whirlpool of
speculation. When the capital
development of a country becomes a byproduct of the activities of a casino, the
job is likely to be ill-done.”
