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 hand. Therefore, society faces a tradeoff between
efficiency and equality
The term equality and efficiency are similar in that they both refer to benefits to society. However, they are different in that
equality refers to uniform distribution of those benefits and efficiency refers to maximizing benefits from scarce resources

allows each country to consume at a point outside its production possibilities frontier

a decrease in the demand for energy drinks
If a surplus exists in a market, then we know that the actual price is
above the equilibrium price, and the quantity supplied is greater than quantity demanded
A decrease in supply will cause the the largest increase in price when
both supply and demand are inelastic
A good will have a more inelastic demand, the
broader the definition of the market
A tax on the buyers of cameras encourage
buyers to demand a smaller quantity at every price
Positive statements are
claims about how the world is
Equilibrium price must decrease when demand
decreases and supply does not change, when demand does not change and supply increases, and when demand decreases and supply increases simultaneously
Two goods are substitutes when a decrease in the price of one good
decreases in quanity demanded for the other good
Savion is restoring a care and has already spent $4,000 on the restoration. He expects to be able to sell the car for $5800. Savion discovers that he needs to do an additional $2400 of work to make the car worth $5800 to potential buyers. He could also sell the car now, without completing the additional work for $3800. What should he do
he should sell the car for 3,800$

helps to explain how the economy is organized
In the market for goods and services in the circular-flow diagram
helps to explain how the economy is organized

it is impossible to produce more of one good without producing less of the other
Demand is said to be inelastic if
the quantity demanded changes only slightly when the price of the good changes.
Cross-price elasticity of demand measures how
the quantity demanded of one good changes in response to a change in the price of another good.
If something happens to alter the quantity supplied at any given price, then
the supply curve shifts
When a country has a comparative advantage in producing a certain good
then specializing in the production of that good and trading for other goods could allow that country to consume at a point beyond its production possibilities frontier
