The negative slope of the PPF demonstrates the concept of:
trade-offs.
"Unexploited gains from trade exist when at least one potential buyer places a value on a good that is higher than the cost of producing the good to at least one potential seller." This statement is:
true. If this buyer and this seller were to trade, producer surplus or consumer surplus (or both) would be generated.
"According to the supply and demand model, all else equal, if the technology used to produce a good improves, supply will increase, causing the price to fall, which causes the quantity demanded to rise as well." This statement is:
true. The supply curve moved, and the equilibrium point moved along the fixed demand curve.
substitutes
two goods for which a decrease in the price of one leads to a decrease in demand for the other
complements
two goods for which a decrease in the price of one leads to an increase in the demand for the other, e.g. hamburgers and hamburger buns

Imagine that a major car company is producing fuel-efficient hybrid cars during a period of rising gas prices. As a result, dealerships are depleted of inventory, and customers remain on a waiting list. How can we BEST describe this phenomenon?
This is a shortage, because the quantity supplied is less than the quantity demanded.
Imagine that a major car company is producing large, fuel-inefficient SUVs during a period of rising gas prices. As a result, dealerships are overstocked with inventory that is not selling. How can we BEST describe this phenomenon?
