Study Notes

Introduction to Managerial Economics

Economics examines choices individuals and societies make regarding allocation of limited resources.
Key players: Consumers, Firms, Government, External Sector.
Fundamental concepts: Goals and Constraints, Profit and Incentives, Markets and Marginal Analysis.

Goals and Constraints

Goals dictate objectives such as profit maximization or market share.
Constraints refer to limitations in resources and technological capabilities.

Profit and Incentives

Profit serves as a primary motivator for firms' decisions.
Incentives influence consumer behavior and firm operations.

Markets and Marginal Analysis

Market dynamics are analyzed using marginal components to determine the optimal decision-making approach.

Basic Economic Concepts

Accounting Costs vs Economic Costs: Accounting focuses on explicit costs; economic costs consider both explicit and implicit (opportunity) costs.
Opportunity Cost: The value of the next best alternative forgone when a choice is made.
Present Value vs Future Value: Present value measures current worth based on expected future cash flows, highlighting the opportunity cost of waiting.
Short-term vs Long-term: Distinctions between immediate factors affecting decisions versus those that impact future outcomes.

Fundamental Economic Questions

What gets produced?: Determines allocation of resources to various goods and services.
How is it produced?: Involves choices regarding production methods and technologies.
Who gets it?: Addresses the distribution of goods among consumers, influenced by income and preferences.

Goods Types

Capital Goods: Assets used in the production of goods and services.
Consumer Goods: Products purchased for direct consumption.

Demand Dynamics

Understanding the differences between needs, wants, and demand is crucial in consumer behavior analysis.
Demand is influenced by price, consumer preferences, and availability of substitutes.

Mathematical Concepts

Familiarity with the equation of a straight line assists in graphical representation of economic relationships, such as demand curves.

Elasticity Overview

Elasticity quantifies demand responsiveness to various factors affecting it.
Measures how quantity demanded changes with price and other determinants.
Critical for understanding consumer behavior in response to price adjustments.

Types of Elasticity

Price Elasticity: Responsiveness of quantity demanded to price changes.
Income Elasticity: Measures demand change due to variations in consumer income.
Cross Elasticity: Gauges demand change due to price changes of related goods.

Measurement Methods

Point Elasticity: Calculated using the formula (\frac{\Delta Q}{Q} / \frac{\Delta P}{P}).
Arc Elasticity: Average elasticity between two points, reduces bias from point calculations.

Price Elasticity Details

Analyzed through percentage changes in quantity and price.
Sign indicates the nature of elasticity; greater than 1 signifies demand is elastic, less than 1 indicates inelasticity.

Total Revenue Implications

Price decreases affect total revenue depending on elasticity:
- Elastic (Ep > 1): Total Revenue increases
- Unitary (Ep = 1): Total Revenue remains constant
- Inelastic (Ep < 1): Total Revenue decreases

Factors Influencing Price Elasticity

Availability of substitutes affects consumer options and responsiveness.
Time length impacts how quickly quantity demanded adjusts to price changes.

Income Elasticity of Demand

Formula: (\frac{\Delta Q}{Q} / \frac{\Delta I}{I})
Positive values indicate normal goods, necessities have low elasticity (0 < EI < 1), luxuries exhibit high elasticity (EI > 1), and inferior goods show negative elasticity (EI < 0).

Cross Elasticity of Demand

Formula: (\frac{\Delta Qx}{Qx} / \frac{\Delta Py}{Py})
Positive cross elasticity indicates substitute goods, negative values suggest complementary goods.
High cross elasticity signals close substitutes; near-zero values suggest independence of goods.
