What is the equilibrium price and equilibrium quantity of bagels?
Equilibrium price = $5; Equilibrium quantity = 100 units.
Does this economy experience constant or increasing opportunity costs? How can you tell?
Increasing Opportunity costs. The PPF is bowed out because of increasing opportunity cost/ slope.

Describe the situations where price ceilings and price floors have no effects.
If Price ceiling is set above equilibrium price, it will have no effect on market outcomes. We say it is not-binding. Similarly, if Price Floor is set below equilibrium price, we say it is Not-binding as it will have no effect on market outcomes.
Explain how the price of a good can rise at the same time that it becomes relatively cheaper.
If the absolute price of a good rises less than the rise in the absolute price of other goods, we can say the good is becoming relatively cheaper. For example, if the absolute price of a pen is $ 1 and the absolute price of a pencil is 10 cents ($ 0.1), the relative price of 1 pen is 10 pencils. Now let the absolute price of a pen rise to $ 1.20 at the same time that the absolute price of a pencil rises to 20 cents. As a result, the relative price of 1 pen falls to 6 pencils. That is, the absolute price of pens rises at the same time that pens become relatively cheaper.
Explain why government actions designed to make home-buying easier actually made it harder.
Lower down payments + Lower interest rates → Easier-to-obtain loans → Higher demand for houses → Higher house prices
What is an opportunity cost? What is your opportunity cost of doing this homework assignment?

What does scarcity mean? Explain the notion that "Scarcity affects everyone in the world-the rich and the poor alike."
Scarcity refers to the condition in which our wants are greater than the limited resources available to satisfy those wants. Scarcity affects everyone in the world- the rich and the poor alike. The rich may be able to satisfy more of their wants for tangible goods (houses, cars) than most people, but they still may not have the resources to satisfy all their wants. Their wants might include more time with their children, more friendship, no disease in the world, peace on earth, and a hundred other things that they don't have the resources to "produce".
complement
two goods are said to be complements if they are used jointly in consumption. If two goods are complements, the demand for one rises as the price of the other falls (or the demand for one falls as the price of the other rises).
substitute
two goods are said to be substitutes if they satisfy similar needs or desires; If two goods are substitutes, the demand for one rises as the price of the other rises (or the demand for one falls as the price of the other falls)
