Opportunity cost: Taken into account for economic decisions. Opportunity Cost is the “next best” or “alternative” benefit from an investment Sunk costs: Never taken into account for economic decisions. Marginal Analysis: Used for profit maximization (deciding how much to produce) where TR and TC are functions of quantity. To maximize profits we take derivative=0

For profit maximization, marginal revenue should be equal to marginal costs for EACH activity. If MR > MC – increase production If MR < MC – decrease production Demand Curve is the Marginal Benefit curve Consumer Surplus = Net benefit to customers = Willingness to pay – total paid. (Area under the demand curve above the price line) Demand and elasticity Demand shows quantity purchased as a function of price. Managers’ Knowledge of demand is critical because it helps in:
• Making production decisions • Defining market structure • Taking strategic and operational decisions

Price Elasticity of Demand is measure of responsiveness i.e. % Change in quantity demanded due to a 1% change in Price Demand is more elastic, • Greater the availability of other substitutes • Greater the time frame • Greater the good’s share of the budget • Lower the switching costs Income Elasticity of Demand
• Positive: Normal Good • Negative: Inferior Good
Cross Price Elasticity of Demand (change in demand of one good based on change in price of another)
• Positive: Substitutes • Negative: Complements
