Study of how people make choices under conditions of scarcity and of the results of those choices for society.
Shift in Supply
Supply increases when sellers are willing to offer more for sale AT EACH POSSIBLE PRICE. *-Moves the ENTIRE supply curve to the right* Supply decreases when sellers are willing to offer less for sale AT EACH POSSIBLE PRICE. *-Moves the ENTIRE supply curve to the left*
An Arizona student claims to have spotted a UFO over the desert outside of Tucson. How will this claim affect the supply (not the quantity supplied) of binoculars in Tucson stores?
Supply will not change. The demand for binoculars is likely to increase, leading to an increase in price and quantity supplied (BUT NO CHANGE IN SUPPLY).
The Cost-Benefit Principle
Take an action if and ONLY if the EXTRA benefits are at least as great as the EXTRA costs.
The Scarcity Principle states...
That although we have boundless needs and wants, the resources available to us are limited, so having more of one good thing usually means having less of another.
The Cost-Benefit Principle states...
That an individual (or a firm or a society) should only take an action if, and only if, the extra benefits from taking the action are at least as great as the extra costs.
Suppose the Nepal invests less in new factories and equipment than does the US. This will likely cause:
The US's production possibilities curve to shift outward faster than Nepal's.
The Greatest security for workers is....
The ability to adapt quickly to changing circumstances.
Aggregation
The adding up of individual economic variables to obtain economy-wide totals. -Aggregate measurements in dollar values allow economists to compare broad categories of goods and services, such as exports and imports. -Aggregation often obscures the fine detail of an economic situation.
Excess Demand (Shortage)
The amount by which quantity demanded exceeds quantity supplied when the price of a good lies below the equilibrium price.
Excess Supply (Surplus)
The amount by which quantity supplied exceeds quantity demanded when the price of the good exceeds the equilibrium price.
Nominal Interest Rate (or Market Interest Rate)
The annual percentage increase in the nominal value of a financial asset. -Nominal interest rates are the most commonly stated rates.
Real Interest Rate
The annual percentage increase in the purchasing power of a financial asset. *Real Interest Rate = Nominal Interest Rate - Inflation*
Rate of Inflation
The annual percentage rate of change in the price level.
Economic Surplus
The benefit of taking an action MINUS its cost. *Economic Surplus = Total Benefits - Total Costs*
Income Effect
The change in the quantity demanded of a good that results because a change in the price of a good changes the buyer's purchasing power. *Buyers' overall purchasing power goes down*
Substitution Effect
The change in the quantity demanded of a good that results because buyers switch to or from substitutes when the price of the good changes. *Buyers switch to substitutes when price goes up*
If one fails to account for implicit costs in decision making, then applying the cost-benefit rule will be flawed because:
The costs will be UNDERstated
Standard of Living
The degree to which people have access to goods and services that make their lives easier, healthier, safer, and more enjoyable.
Buyer's Surplus
The difference between the buyer's reservation price and the price they actually pay.
Total Surplus
The difference between the buyer's reservation price and the seller's reservation price.
Seller's Surplus
The difference between the price received by the seller and their reservation price.
Unemployment Rate
The fraction of people who would like to be employed but can't find work. *% of the labor force that is out of work*
Marginal Benefit
The increase in Total Benefit from 1 ADDITIONAL unit of an activity.
Marginal Cost
The increase in Total Cost from 1 ADDITIONAL unit of an activity.
Socially Optimal Quantity
The quantity of a good that results in the maximum possible economic surplus from producing and consuming the good. *The Socially Optimal Quantity maximizes total surplus for the economy from producing and selling a good*
Rate of Inflation
The rate at which prices in general are increasing over time.
If Country A and Country B have the same population size, then the standard of living in these 2 countries can still be different depending on:
The relative sizes of total output.
Market Value
The selling prices of goods and services in the open market. *Aggregate measure of quantities produced* -More expensive items receive a higher weighting. -Willingness to pay is an indication of benefit received from the good.
Seller's Reservation Price
The smallest dollar amount for which a seller would be willing to sell an additional unit. *Generally equal to Marginal Cost*
Macroeconomics
The study of the performance of national economies and the policies governments use to try to improve that performance.
Which of the following is NOT a determinant of the demand for gasoline?
The supply of gasoline. *A change in supply does NOT change demand* ARE Determinants: -Consumers' incomes -The price of diesel -The price of automobiles
Fisher Effect
The tendency for nominal interest rates to be high when inflation is high and low when inflation is low.
Labor Force
The total number of employed and unemployed people in the economy. *= employed + unemployed*
Opportunity Cost [of that activity]
The value of what must be foregone in order to undertake an activity.
Opportunity Cost
The value of what must be foregone in order to undertake an activity. -Explicit AND Implicit costs. -NOT the combined value of ALL possible activities! *Opportunity Cost = Explicit Costs + Implicit Costs* --Opportunity cost considers ONLY your best alternative!
Real Wage
The wage paid to workers measured in terms of purchasing power. *The real wage for any given period is calculated by dividing the nominal (dollar) wage by the CPI for that period*
Average Benefit
Total benefit divided by the number of units.
Average Cost
Total cost divided by the number of units.
Complements
Two goods are complements in consumption if an increase in the price of one causes a leftward shift in the demand curve for the other (or if a decrease causes a rightward shift).
Substitutes
Two goods are substitutes in consumption if an increase in the price of one causes a rightward shift in the demand curve for the other (or if a decrease causes a leftward shift).
To see how much output has grown...
Use ONLY the changes in quantities. *Hold prices constant*
Nominal GDP
Values output in the current year using prices from the current year. *Nominal GDP is the current dollar value of production*
Real GDP
Values output in the current year using the prices from the base year. *Real GDP measures the physical volume of production*
The Scarcity Principle (aka "No Free-Lunch Principle")
We have boundless wants, but resources are limited. *Having more of 1 good thing USUALLY means having less of another.*
Income Approach to GDP
When a good is sold, its proceeds are distributed to workers or business owners. *GDP=Labor income + Capital income*
Maximizing GDP will not necessarily maximize national well-being
Whether increases in output increase welfare is a case-by-case issue.
According to the Incentive Principle, when the benefit of an action falls, a person...
Will be less likely to take the action.
A price ceiling that is set above the equilibrium price:
Will have NO effect on the market.
A rational person is someone...
With well-defined goals who tries to fulfill those goals as best they can.
Discouraged Workers
Would like to have a job but they have not looked for work in the past 4 weeks [because they believe there are no jobs available]. *Counted as out of the labor force* -Could be counted as unemployed but they are not.
