BEC 1 - Economic Concepts & Strategy Flashcards
Economics is the study of
study of allocating scarce resources to satisfy unlimited wants
Microeconomics
decisions of, interactions among, various individual economic agents (household and firms)
Demand Curve Slope
Slopes Down
Demand Curve P & Q relationship
inverse relationship between P & Q of a product/service that a group of consumers are willing to buy at a particular time
Demand Curve Shift Outward
Shifts outward because Q-Demanded becomes larger for each and every price demanded
Demand Curve shifts inward
Shifts inward because Q-Demanded becomes smaller for each and every price demanded
Reasons for Direct Relationship (Increase Demand Curve)
- Price of Substitute Good
- Expectations of Price Changes
- Income (Normal Goods)
- Extent of the Market
Reasons for Inverse Relationship (Decrease Demand)
Price of a complement good
Income (inferior goods)
Consumer Boycotts
Indeterminate relationship (demand)
changes in consumer tastes affects demand depending on favor or disfavor of the specific product
Elasticity
measures sensitivity of something to changes in something else
Total Revenue From Price Change depends on
Price Elasticity of Demand
Price Elasticity of Demand
Measures how responsive the Q-Demanded is to a change in Price
Price Elasticity of Demand Formula
%Q-Demand / %Price É. ABSOLUTE VALUES
If E>1, it is
Elastic
Price Elasticity of Demand (ARC METHOD)
(Change in Q Demanded / Avg Q Demanded) / (Change in Price / Avg Price)
Income Elasticity of Demand
measures the effect of changes in consumer income on changes in Q demanded of a product
Income of Elasticity of Demand
(%Change in Q Demanded) / (%Change in Income)
Positive Income Elasticity indicates
NORMAL GOOD, (as I increases, Q-Dem of normal good also increases)
Negative Income Elasticity indicates
INFERIOR GOOD (As I increases, Q-med decreasesÉ. Used car vs New Car)
Inelastic Goods are normally
necessities (cancer drug)
Price Elasticity > 1.0
ElasticÉ If Price Increases, Total Revenue Decreases (vice versa)
Price Elasticity < 1.0
InelasticÉ If Price Increases, Total Revenue Increases (vice versa)
Price Elasticity = 0
Unit ElasticÉ If Price Increase, Total Revenue remains constant
Income Elasticity Point of Inflection
Zero
IE>+0 - Normal GoodÉ. If IE
