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
Supply Curve Shifts (Direct Relationship)
of Producers
Government Subsidies
Price Expectations
Reductions if Costs/Tech Advance
Supply Curve Shifts (Indirect Relationship)
Increases in Production costs, Price of Other Products
Cross Elasticity of Demand
(%Change in Qd X / %Change in Price of Y)
Cross Elasticity of Demand Point of Inflection
Zero (Positive # = Substitute, Negative # = Complement)
Elasticity of Supply
%Change in Qs / %Change in Price É. ABSOLUTE VALUES
Economic Profit
Excess of normal profit rate (suppliers entering the market)
Price Ceiling
Below Equilibrium, creates a shortage
Price Floor
Above Equilibrium, creates a surplus
Economic Rents
The Difference between Chosen Route and Opportunity Cost
If Demand and Supply BOTH increase (decrease)
Equilibrium Price is INDETERMINATE (either way)
Q-Purchased increases (decreases)
If Demand INCREASES and Supply DECREASES
Equilibrium Price INCREASES (follows Demand)
Q-Purchased is INDETERMINATE
Total Utility is Maximized When
MUa = MUb
If MUa > MUb
MUa Q-demanded will INCREASE & MUb Q-demanded will DECREASE until MUa=Mub
Consumer Utility is Maximized when
Budget Constraint and Indifference Curve Tangent
Profit Maximization
MR = MC
Personal Disposable Income
Income - Taxes + Govt Benefits
Marginal Propensity to Consume (MPC)
Change in Spending / Change in Income
Marginal Propensity to Save (MPS)
Change in Saving / Change in Income
MPC + MPS =
1
Increase in GDP (multiplier Effect)
(1/MPSaving) x (Change in Spending)
Marginal Revenue Product
increase in total revenue received from sale of one more unit of input/resource
If MR > MC (operating below capacity)
Price Decreases to Total Revenue Increases (Sales Increases and MR Decreases)
Operating Below capacity
in excess of VCÉ when capacity is reached (MR=MC), any additional unit will also increase Fixed Costs
Long Run Costs (By Definition)
Total Costs = Variable Costs (no fixed costs)
Returns to Scale Formula
%Increase in Output / %Increase in Input
Increasing Returns to Scale indicates
Falling price per unit (RTS>1.0)
Decreasing Returns to Scale indicates
Increasing Price Per Unit (RTS<1.0)
Constant Returns to Scale indicates
No Effect on Price (RTS=1.0)
Pure/Perfect Competition (traits)
- Large # of Buyers/Sellers
- Same Products (Homogenous)
- No Non-Price Competition (IE No Ads)
- No Barriers to Entry/Exit
- No Price Contracts
- Demand Curve is Elastic (Horizontal)
Monopolistic Competition (traits)
NAME?
Oligopoly (traits)
- Small # of large Producers
- Homogenous/Heterogenous Products
- Significant barriers for entry ($$, Time, Licenses)
- Non-Price Competition
- Rival Actions are observed
- Kinked D-Curve
Pure Monopoly (Traits)
NAME?
Competition Analysis
Data analysis for understanding/predicting competition
Target market
who are our customers and why are they our customers
Strategic Planning
SWOT (Strengths, Weaknesses, Opportunities, and Threats)
or
Mission Statement, Goals/Objectives, Actions (Assessment and Data Analysis)
Product Differentiate Strategies
physical, perceived, and customer service for:
- makes the firms sales less responsive to changes in the prices charged by other competitors
- allows to charge different prices for different products
- charge higher prices
Cost Leadership Strategies
cutting costsÉ
- Process reingineering (redesign processes)
- lean manufacturing (ID misuse of resources)
- supply chain management
Supply Chain Management
Part of Cost Leadership StrategiesÉ might be able to operate with leaner inventories if all parts of the Supply Chain shared information
