Study Notes

Branches of Economics

Microeconomics studies individual economic agents like households and firms, focusing on supply, demand, market structures, and pricing.
Macroeconomics examines the entire economy, including GDP, inflation, unemployment, fiscal, and monetary policy.
Econometrics uses statistical methods to analyze economic data and test economic theories.
Development economics focuses on economic growth and development in underdeveloped economies, considering poverty, inequality, and public policy.
Behavioral economics incorporates psychology to understand economic decision-making, acknowledging that human behavior is not always rational.
International economics studies trade, investment, and cross-national economic interactions, including exchange rates and finance.

Key Economic Concepts

Scarcity: Limited resources versus unlimited wants, necessitating choice and opportunity cost.
Supply and Demand: The interaction of desired quantities at different price points, leading to equilibrium.
Opportunity Cost: The value of the next best alternative sacrificed in a decision.
Incentives: Factors motivating individual and organizational actions. Economic theory assumes people respond to incentives.
Efficiency: Maximizing output with available resources, minimizing waste and maximizing benefits.
Equity: Fairness in resource distribution and economic outcomes. Often a goal in contrast with efficiency.
GDP (Gross Domestic Product): The total market value of goods and services produced within a country's borders in a specific time frame.
Inflation: The sustained increase in the general price level of goods and services.
Unemployment: The percentage of the labor force actively seeking work but unable to find it.

Market Structures

Perfect Competition: Many buyers and sellers, homogenous products, free entry/exit, price takers with zero long-run economic profit.
Monopoly: One seller, unique product, high barriers to entry, price makers, potentially earning economic profit.
Monopolistic Competition: Many sellers, differentiated products, some market power, slight barriers to entry.
Oligopoly: A few large firms controlling a significant portion of the market, characterized by strategic interactions and interdependence.

Economic Systems

Capitalism: Private ownership of production means, market resource allocation, individual incentives emphasized.
Socialism: Collectivism, social ownership, central planning, greater emphasis on equity than efficiency.
Mixed Economy: Combines elements of capitalism and socialism, integrating private and public ownership in resource allocation; common globally.

Role of Government in the Economy

Providing public goods (national defense, street lighting) not efficiently provided by the private sector.
Addressing market failures (externalities, information asymmetry) where markets don't allocate resources optimally.
Redistributing income through taxes and welfare programs to reduce inequality.
Regulating industries (controlling monopolies, protecting consumers, ensuring safety standards).

Economic Growth

Factors contributing to economic growth include technological advancement, investment in human capital, and infrastructure improvements.
Economic growth is often linked to rising living standards, labor productivity, efficient resource allocation, and innovation.
Economic growth can have positive outcomes (wealth, employment) and negative outcomes (environmental concerns).
