2. Which way does the curve move?
3. What happens to P and Q?
● Important – There is a difference between
“demand” and the “demand curve”.

Planned Economies vs. Capitalism
● The major issue:
Who knows what’s best – the
government or the people?
● With Adam Smith’s “invisible hand,” people
and businesses “vote” with their dollars.
– The ‘best’ survive, the ‘poor’ fail
– Allocation is done by voting with dollars
– Have even used this to predict elections
