The price elasticity of demand for a good is 5, then a 10% increase results in a
50% decrease in quantity demanded.

Efficiency means that
society is getting the most it can from its scarce resources.
On a demand curve, when the price moves from 7 to 5 and the quantity moves up from 12 to 20, the price elasticity of demand is equal to
1.5.

Shifting a curve out so it intersects the x and y axes at higher values represents
a general technological advance
IN the markets for goods and services in the circular-flow diagram,
firms provide households with output.
Suppose that the price falls along a demand curve and the quantity increases. The area between the initial and final price represents
additional consumer surplus to initial consumers when the price falls.
Trade between countries
allows each country to consume at a point outside its production possibilities frontier.
Dale is a guitar teacher and Terrence is a tile layer. If Dale teaches Terrence's daughter to play guitar in exchange for Terrence tiling Dale's floor,
both Dale and Terrence are made better off by trade.
demand is said to be price elastic if
buyers respond substantially to changes in the price of the good
Steak and chicken are substitutes. A sharp reduction in supply of steak would
decrease consumer surplus in the market for steak and increase producer surplus in the market for chicken.
The Surgeon General announces that eating chocolate increases tooth decay. As a result, the equilibrium price of chocolate,
decreases, and the producer surplus decreases.
Cadence says that she would smoke one pack of cigarettes each day regardless of price. Cadence's
demand for cigarettes is perfectly inelastic.
The distinction between efficiency and equality can be described as follows:
efficiency refers to maximizing the size of the pie; equality refers to distributing the pie fairly among members of society.
An example of positive analysis is studying
how market forces produce equilibrium.
If the supply curve is S and the demand curve shifts from D to D', what is the change in producer surplus?
increase by $3,125
Absolute advantage is found by comparing different producers'
input requirements per unit of output.
The adage, "there aint no such thing as a free lunch," means
people face tradeoffs
Candice is planning her activities for a hot summer day. She wants to swim at the pool and see the latest movie. She can only choose one activity cuz they are at the same time. This is the principle that
people face tradeoffs.
Assume that a 4% increase in income results in a 2% increase in quantity demanded of a good. The income elasticity of demand is
positive, and the good is a normal good.
Alana decides to spend 2 hours working overtime rather than going shopping with her friends. She earns $11 per hour for overtime work. Her opportunity cost of working is
the enjoyment she would have received had she gone shopping.
You are in charge of the local city-owned aquatic center. You need to increase the revenue generated by the aquatic center to meet expenses. The mayor advises you to increase the price of a day pass. The city manger recommends reducing the price of the day pass. You realize that
the mayor thinks demand is inelastic and the city manager thinks demand is elastic.
Suppose a nation is currently producing at a point inside its production possibilities frontier. We know that
the nation is not using all available resources or is using inferior technology or both.
Efficiency is represented by what points on a curve
the points on the curve itself (not inside or above it)
Income elasticity of demand measures how
the quantity demanded changes as consumer income changes.
Efficiency in a market is achieved when
the sum of producer surplus and consumer surplus is maximized.
The marginal benefit Joseph gets from purchasing a fourth pair of shoes is
the total benefit he gets from purchasing four pairs of shoes minus the total benefit he gets from purchasing three pairs of shoes.
Economics is the study of how society manages its
unlimited wants and limited resources
A seller's opportunity cost measures the
value of everything she must give up to produce a good.
The opportunity cost of an item is
