Economics Flashcards
Macroeconomics
Deals with aggregate economic quantities, such as national output and national income, and is rooted in microeconomics
Equilibrium price
The quantity willingly demanded by consumers at that
price is just equal to the quantity willingly supplied by firms
Microeconomics
Deals with markets and decision making of individual economic units, including consumers and businesses. Microeconomics is a logical starting point for the study of economics
Microeconomics classifies private economic units inro what two groups
- Consumers (or households)
- Firms
Law of Demand
The believe that as the price of a good rises, buyers will choose to buy less of it and as its price falls, they buy more.
Theory of the Consumer
Deals with consumption (the demand of goods and services) by utility-maximizing individuals (i.e., individuals who make decisions that maximize the satisfaction received from present and future consumption.
Three important topics concerning the demand side of the model:
- Elasticities
- Substitution and Income Effects
- Normal and Inferior Goods
The Theory of the Firm
Deals with the supply of goods and services by profit-maximizing firms
Demand Function
A function is a relationship that assigns a unique value
to a dependent variable for any given set of values of a group of independent variables
Own Price
used by economists to underscore that the reference is to the price of a good itself and not the price of some other good.
Inverse Demand Function
In economics, an inverse demand function is the mathematical relationship that expresses price as a function of quantity demanded (it is therefore also known as a price function).
Demand Curve
The demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded for a given period of time. In a typical representation, the price appears on the left vertical axis while the quantity demanded is on the horizontal axis.
