ECON midterm
Suppose that you have received $650 as a birthday gift. You can spend it today or you can put the money in a savings account for a year and earn 2 percent interest. The opportunity cost of spending the money today, in terms of what you could have after one year, is
$663.00
Demand is said to be inelastic if
the quantity demanded changes only slightly when the price of the good changes
If a 16 percent increase in price for a good results in a 7 percent decrease in quantity demanded, the price elasticity of demand is
0.44
If a 39 percent change in price results in a 35 percent change in quantity supplied, then the price elasticity of supply is about
0.90, and supply is inelastic
Nick and Tabitha are two woodworkers who both make tables and chairs. In one month, Nick can make 9 tables or 27 chairs, whereas Tabitha can make 16 tables or 48 chairs. Given this, we know that the opportunity cost of 1 chair is
1/3 table for Nick and 1/3 table for Tabitha.
Suppose that a worker in Caninia can produce either 2 blankets or 8 meals per day, and a worker in Felinia can produce either 5 blankets or 1 meal per day. Each nation has 10 workers. For many years, the two countries traded, each completely specializing according to their respective comparative advantages. Now war has broken out between them and all trade has stopped. Without trade, Caninia produces and consumes 10 blankets and 40 meals per day and Felinia produces and consumes 25 blankets and 5 meals per day. The war has caused the combined daily output of the two countries to decline by
15 blankets and 35 meals.
Suppose the price of a bag of frozen chicken nuggets decreases from $6.60 to $6.50 and, as a result, the quantity of bags demanded increases from 600 to 620. Using the midpoint method, the price elasticity of demand for frozen chicken nuggets in the given price range is
2.15

Economists sometimes give conflicting advice because
economists have different values and scientific judgments.
A typical society strives to get the most it can from its scarce resources. At the same time, the society attempts to distribute the benefits of those resources to the members of the society in a fair manner. However, redistributing income from rich to poor reduces the reward for working hard. Therefore, society faces a tradeoff between
efficiency and equality
When society gets the most it can from its scarce resources, then the outcome is called
efficient

elastic because there are many close substitutes for grape-flavored Hubba Bubba

equality refers to uniform distribution of those benefits and efficiency refers to maximizing benefits from scarce resources.

increase both competition and specialization
When the price of candy bars is $1.20, the quantity demanded is 490 per day. When the price falls to $1.00, the quantity demanded increases to 500. Given this information and using the midpoint method, we know that the demand for candy bars is
inelastic.

input requirements per unit of output.

is an inferior good with an income elasticity of -1 and soy-burgers are normal goods with an income elasticity of 1.

If we add the respective quantities that each shop would produce and sell at each of the six bait and tackle shops when the price of worms is $2 per bucket, $2.50 per bucket, and $3 per bucket, and so forth, we have found the
market supply curve
Suppose the interest rate is measured along the vertical axis on a graph. When the interest rate changes, there will be a
movement along the curve
Chloe's college raises the cost of room and board per semester. This increase raises Chloe's opportunity cost of attending college
only if the amount she would have to pay for room and board if she didn't attend college rose by less than the increase in the amount her college charges. An increase in opportunity cost reduces Chloe's incentive to attend college.

rises, the quantity supplied of the good rises.
The quantity supplied of a good is the amount that
sellers are willing and able to sell.

the y-coordinate and the vertical location of the point.
Aiden and Zaria charge people to park on their lawn while attending a nearby craft fair. At the current price of $10, six people park on their lawn. If they raise the price to $15, they know that only five people will want to park on their lawn. Whether they have six or five cars parked on their lawn does not affect their costs. From this information it follows that
they would do better charging $15 than $10.
The y-coordinate of an ordered pair specifies the
vertical location of the point
