Study Notes

Introduction to Economics

Economics is the social science that studies how societies allocate scarce resources to satisfy unlimited wants and needs.
It encompasses various concepts, including production, consumption, distribution, and exchange of goods and services.
Key areas of study include microeconomics, which focuses on individual agents and markets, and macroeconomics, which analyzes the overall performance of the economy.

Microeconomics

Microeconomics examines the behavior of individual economic agents, such as consumers and firms.
It explores concepts like supply and demand, market structures, and firm behavior.
Supply and demand are fundamental concepts that explain how prices are determined in markets.
Demand represents the willingness of consumers to buy a good or service at various prices, while supply represents the willingness of producers to sell a good or service at various prices.
Market structures, such as perfect competition, monopoly, oligopoly, and monopolistic competition, describe the nature of competition in different markets.
Firms aim to maximize profits, a key motivational factor in microeconomics.
Firms' production choices depend on input costs and factors like technology.

Macroeconomics

Macroeconomics analyzes the overall performance of the economy and its aggregate behavior.
It studies economic indicators such as GDP, inflation, unemployment, and interest rates.
Gross Domestic Product (GDP) measures the total value of goods and services produced within a country in a specific period.
Inflation refers to the rate of increase in the general price level of goods and services in an economy.
Unemployment measures the percentage of the labor force that is actively seeking employment but unable to find work.
Interest rates are the cost of borrowing money and affect consumer spending and investment decisions.

Key Economic Schools of Thought

Classical economics: Emphasizes the self-regulating nature of the market and the importance of free markets.
Keynesian economics: Advocates for government intervention to manage aggregate demand and stabilize the economy during recessions.
Monetarism: Focuses on the role of money supply in inflation and economic fluctuations.
New classical economics: Combines elements of classical and rational expectations theories.
Behavioral economics: Incorporates psychological insights into economic decision-making.
Institutional economics: Studies social and political institutions that shape economic behavior and outcomes.

Economic Systems

Market economies: Resources are allocated primarily through markets, with limited government intervention.
Command economies: Resources are allocated by a central authority, often the government.
Mixed economies: Combines elements of both market and command economies, with varying degrees of government regulation and intervention.

Economic Growth & Development

Economic growth refers to an increase in the production of goods and services over a period of time.
Economic development encompasses a broader range of changes including improvements in living standards, education, health, and infrastructure.
Factors influencing economic growth include technological advancements, human capital, and infrastructure.
