ECON Micro Flashcards
Definition of Economics
Economics studies how individuals make choices to allocate limited resources to satisfy unlimited wants.
Definition of Scarcity
The fundamental economic problem of having limited resources to meet unlimited wants.
Definition of Opportunity Cost
The value of the next best alternative forgone to satisfy a want or obtain something.
What are Resources and Factors of Production?
*Land: Natural resources, mineral deposits, climate.
*Labor: Human effort and skills, e.g., accountants, plumbers.
*Capital: Machinery and buildings used in production.
*Entrepreneurship: Organizing resources, raising capital, making business policy decisions, taking risks.
Definition of Goods
Items that provide satisfaction.
Definition of Economic Goods
Scarce goods where demand exceeds supply.
Definition of Services
Intangible tasks performed for others, such as medical or legal assistance.
Definition of Market
Arrangements for exchanging goods/services.
Definition of Price System
Constantly changing prices due to supply and demand; signals scarcity and abundance.
Definition of Voluntary Exchange
Mutually beneficial trade making both parties better off.
Definition of Demand
Schedule showing quantity of a good/service people will purchase at various prices.
Definition of Law of Demand
A negative or inverse relationship between price and quantity demanded, holding all things constant.
– At a higher price people buy less; at a lower price people buy more.
– Relative prices must be distinguished from money prices since people respond to changes in relative prices.
Definition of Supply
A schedule showing the relationship between price and the quantity supplied for a specified time period, other things being equal.
The amount of a product or service that firms are willing to sell at alternative prices.
What is the Law of Supply?
Firms will produce and offer for sale more at a higher price; firms offer less at a lower price.
What is the Demand Curve?
Graph with a negatively sloped line showing the inverses relationship between price and quantity demanded.
(other things being equal)
What is the Supply Schedule vs Supply Curve?
Schedule: Graph relating prices to quantity supplied at each price.
Curve: Graph representing the supply schedule
A positively sloped line (curve) showing the direct relationship between price and quantity supplied, all else being equal
Shifts and Equilibrium: How does Income Effect Determinants of Demand?
With Normal Goods demand increases as as income rises.
With Inferior Goods demand falls as income rises.
Shifts and Equilibrium: What are Determinants of Supply
Technology and productivity, input prices, price expectations, taxes/subsidies, number of firms in the industry.
Shifts and Equilibrium: How do Tastes and Preferences affect Determinants of Demand?
– The prices of related goods
Substitutes
Two goods are substitutes when a change in the price of one causes a shift in demand for the other in the same direction as the price change.
Complements
Two goods are complements when a change in the price of one causes an opposite shift in the demand curve for the other.
How do future price expectations affect the Market Supply Curve?
Sellers who expect the price of an item in the market to rise in the future reduce the amount that they make available for sale today.
Buyers who anticipate a higher price of that item will seek to purchase more units of the item today.
Thus, the market supply curve will shift leftward, and simultaneously the market demand curve will shift rightward.
Determinants of Demand
Income
Tastes and preferences
The price of related goods
Expectations
Market size (number of buyers)
Shifts and Equilibrium: How do Expectations affect Determinants of Demand?
Future prices
Income
Product availability
When the price of a good goes up, what happens?
When the price of a good goes down, what happens?
What are we holding constant in these situations?
People buy less of it, other things being equal.
People buy more, other things being equal.
– Income
– Tastes and preferences
– Prices of other goods
– Many other factors
Shifts and Equilibrium: What are Changes in Demand/Supply?
Shifts in curves due to non-price factors.
What is Equilibrium Price?
Price where quantity demanded equals quantity supplied.
What are Market Dynamics?
Adjustments to new equilibrium due to shifts in demand and supply.
Price Controls and Rationing: What is the Price Ceiling?
Legal maximum price; causes shortages if below equilibrium.
Price Controls and Rationing: What is the the Price Floor?
Legal minimum price; causes surpluses if above equilibrium.
Price Controls and Rationing: What is Nonprice Rationing?
Methods include queues, random assignment, coupons.
Price Controls and Rationing: What is the Black Market?
Results from price ceilings, where goods are sold illegally at higher prices.
What is Economic Growth?
Illustrated by an outward shift of the production possibilities curve.
Over time, it is possible to have more of everything. The PPC can be used to illustrate the trade-off between present and future consumption.
What is Efficiency?
Maximum output with given resources; minimal cost production.
What is Specialization?
Organization of activity among different individuals and regions leads to greater productivity.
Government Interventions: What is Support Price
Government-imposed price floor to prevent prices from falling.
Government Interventions: Minimum Wage
Legal minimum hourly wage; affects employment and wage dynamics.
Government Interventions: Quantity Restrictions
Bans, licensing requirements, import quotas affecting market dynamics.
What is Consumer Surplus?
Difference between willingness to pay and actual payment.
What is Producer Surplus?
Difference between actual revenue and minimum acceptable revenue.
What is Total Surplus?
Combined value of consumer and producer surplus from trade.
What are Incentives?
Rewards for engaging in a particular activity.
The nature of self-interested responses to incentives is the starting point for economic analysis.
What is the Economic Way of Thinking?
A framework to
analyze solutions to economic problems
