Econ Chapter 2
What are the three questions that must be answered in an economic system?
1.) What to produce? 2.) How to produce it? 3.) Who gets what share of the pie?
What are the two reasons the demand curve slopes downward?
1.)As the good or service becomes more expensive, compared to other goods and services, people switch to substitutes. 2.) As the good becomes more expensive, people can't afford to buy as much of it- or some people can't afford any of it
The supply curve illustrates that firms:
increase the quantity supplied of a good when its price rises.
The buyer's reservation price for a particular good or service is the:

maximizes total economic surplus.
The height of the demand curve at any point
the price that the corresponding marginal buyer is willing to pay = the reservation price
A seller's reservation price is generally equal to:
the seller's marginal cost.
The Demand Curve
the set of all price-quantity pairs for which buyers are "satisfied" • Satisfied means being able to buy the amount they want to , given its price
