Suppose that you are spending two hours a day studying economics, and your grade is 85 percent. You want a higher grade and decide to study for an extra hour a day. As a result, your grade rises to 90 percent. Your marginal benefit is the
5 point increase in your grade.
In the figure above, suppose that Mac and Izzie specialize and trade to reach point c. Mac sends Izzie
6 computers in exchange for 6 TVs.
Why do we need to make choices
Because we have to because of scarcity. We have unlimited wants and limited resource

Economics
Is a philosophy of who to make decisions supported by mathematical intuition.
Auto workers negotiate a wage increase. How does this wage hike affect the supply of cars?
It decreases the supply.
Tom takes 20 minutes to cook an egg and 5 minutes to make a sandwich. Jerry takes 15 minutes to cook an egg and 3 minutes to make a sandwich. Both individuals will be better off if
Jerry trades sandwiches in exchange for eggs.
Growers expect that the price of a bushel of wheat will increase in one month. This belief results in
a decrease in current supply of wheat.
Which of the following creates an incentive to increase the amount of an activity?
a decrease in the marginal cost of the activity and an increase in the marginal benefit of the activity
The price of cereal rises. As a result, people have cereal for breakfast on fewer days and eat eggs instead. This behavior is an example of
a decrease in the quantity demanded of cereal because of the substitution effect.
Economic agents
any group or individuals that makes choices
demand side economic agents
consumers and households
Ham and eggs are complements. If the price of ham rises, the demand for eggs will
decrease and the demand curve for eggs will shift leftward.
The demand curve for a normal good shifts leftward if income ________ or the expected future price ________.
decreases; falls
supply side economic agents
firms and businesses
opertunity cost
highest foregone alternative(the best option)
Opportunity cost means the
highest-valued alternative forgone.
All economic questions are about
how to cope with scarcity
Which of the following explains why supply curves slope upward?
increasing marginal cost
The initial supply and demand curves for a good are illustrated in the above figure. If there are technological advances in the production of the good, then the new equilibrium price for the good
is less than $6.
Economics
is the study of choices made by economic agents and a philosophy on how to make efficient decisions.
Scarcity exists because
our wants exceed the resources available to satisfy them.
Harry produces 2 balloon rides and 4 boat rides an hour. Harry could produce more balloon rides but to do so he must produce fewer boat rides. Harry is ________ his production possibilities frontier.
producing on
An increase in the number of suppliers in a market results in a
rightward shift in the supply curve
The law of demand states that, other things remaining the same, the higher the price of a good, the
smaller is the quantity of the good demanded.
Comparative advantage is
the ability to perform an activity at a lower opportunity cost than anyone else.
The quantity demanded is
the amount of a good that consumers plan to purchase at a particular price.
Which of the following influences people's buying plans and does not shift the demand curve?
the price of the good
A bakery can produce either cakes or cookies. If the price of cookies rises, then
the supply curve of cake shifts rightward.
Optimally
to maximize the difference benefit and cost
A lawn service is deciding whether to add an additional employee to its summer crew. The marginal cost of hiring this worker depends on the
total amount paid to only the new worker.
Optimal choices
we have to make optimal choices to divide up the resources.
If the marginal benefit of a good exceeds its marginal cost
we should produce more to achieve efficient use of resources.
