Microeconomic Concepts: Microeconomics 3rd Edition By Karlan And Morduch
Microeconomics examines the behavior of individual entities, such as households, firms, and individuals, within the economy. It focuses on understanding how these entities make decisions and interact in markets.
Fundamental concepts in microeconomics include scarcity, supply and demand, and elasticity. Scarcity refers to the limited availability of resources relative to unlimited wants, leading to choices and trade-offs. Supply and demand analyze the interaction between buyers and sellers, determining market prices and quantities.
Elasticity
Elasticity measures the responsiveness of quantity supplied or demanded to changes in price or other factors. Price elasticity of demand indicates how much quantity demanded changes in response to a price change. Price elasticity of supply measures how much quantity supplied changes in response to a price change.
Consumer Behavior
Consumer behavior analyzes how individuals make decisions about consumption. Factors influencing consumer behavior include preferences, income, prices, and marketing efforts.
Preferences
- Preferences represent consumers’ desires and tastes for goods and services.
- They are subjective and vary among individuals.
- Preferences can be shaped by culture, social norms, and personal experiences.
Firm Behavior
Firm behavior analyzes how firms make decisions about production, pricing, and marketing. Firms aim to maximize profits, subject to constraints such as costs, technology, and competition.
Types of Firms
- Perfectly competitive firms: Numerous small firms selling identical products in a market with no barriers to entry or exit.
- Monopolies: Single firms with exclusive control over a market due to barriers to entry.
- Oligopolies: A few large firms dominate a market, with barriers to entry and interdependence in decision-making.
Market Structures
