chapter 1 - 10 Principles of Econ (eoe)
Principles 1-
People Face
Trade-offs - eg.
trades off as a
student to study
or not, trade off
as a parent. An
economy usually
makes a payment
between "guns"
and "butter"
Economics
acknowledges the
trade-off's that must
exist in society.
Principle 2- The Cost of
Something is what you
give up to get it- The
cost you pay is
sometimes not as
obvious as it seems. eg:
the cost to go to college
is not cost of room,
food etc. But the cost of
your time and earning
potential time.
Principle 3 Rational People think at the
Margin - decisions are made
because of the small but
important incremental
adjustments to a plan of action
eg: whether to take that extra
bit of food, whether an airline
should look at the marginal cost
Principle 4- People to respond to
incentive - People respond to
incentives - the rest is
commentary. eg Gas prices
being high and such its better to
look for other means of
transport, the incnetive of
wearing a seat belt, the
incentive of bus drivers who are
paid by the hour or per
pssagnger trip.
Principle 5- Trade can
make everyone better
off - Trade
competitions between
countries are different
from those in sports.
When one side win
both sides can win
Prinicple 6- Market are usually a
good way to organize economic
activity - allow the invisible
hand of the marketplace to
control the market.
Communisim didn't succeed
because it tried to influence the
prices that the market produce.
Principle 7 - Governments
can sometimes improve
market outcomes - the
government help to police
the efficiency and equality
of a countries population
Principle 8 - A
country's standard
of living depends on
its ability to produce
good and services -
the level productivty
of a country assist in
the growth of the
counrty.
Principle 9 - Prices Rise
when the government
prints too much money
- inflation in a country
can account for the
some of the economic
chanllenges that ,ay
occur in a society
Principle 10 : Society faces a
short-run tradeoff between
inflation and unemployment -
economics have had to agree
that there is a short run trade
off between inflation and
unemployment
