Study Notes

Introduction to Economics

Economics is the study of how societies allocate scarce resources to satisfy unlimited wants and needs.
It's broadly categorized into microeconomics and macroeconomics.

Microeconomics

Focuses on the behavior of individual economic agents like households and firms.
Examines how individuals make decisions in the face of scarcity and how markets function.
Topics include supply and demand, production, cost, market structures (e.g., perfect competition, monopoly).
Analyzes consumer behavior, choices, and the factors influencing their demands.
Investigates the production process, factors of production, and the organization of firms.
Studies market failures like externalities and public goods and the role of government in correcting them.

Macroeconomics

Studies the economy as a whole.
Examines large-scale economic issues like inflation, unemployment, economic growth, and international trade.
Concentrates on aggregate variables such as GDP, inflation rates, and unemployment rates.
Analyzes how these factors interact and influence each other.
Investigates the role of government policies (monetary and fiscal) in stabilizing the economy.
Studies long-run economic growth and development, and factors impacting economic progress.

Key Macroeconomic Concepts

Gross Domestic Product (GDP): The total value of all final goods and services produced within a country's borders in a specific time period.
Inflation: The sustained increase in the general price level of goods and services in an economy over a period.
Unemployment: The percentage of the labor force that is actively seeking employment but unable to find it.
Economic Growth: An increase in the productive capacity of an economy over a period of time, typically measured by the increase in real GDP per capita.
Business Cycles: Fluctuations in economic activity, characterized by periods of expansion and contraction. Expansionary periods are associated with increasing GDP, employment, and consumer confidence. Contractionary periods include recessions and depressions.

Economic Indicators

GDP: A key indicator of overall economic performance; a high GDP suggests a healthy economy.
Inflation Rate: Indicates the rate at which prices are rising; high inflation can cause instability in the market.
Unemployment Rate: Shows the proportion of the labor force without jobs; low unemployment suggests a thriving job market.
Consumer Price Index (CPI): Measures the average change over time in the prices paid by urban consumers for a basket of consumer goods and services.
Producer Price Index (PPI): Measures the average change in selling prices received by domestic producers for their output.

Fiscal Policy

Refers to government spending and taxation decisions to influence macroeconomic conditions and stimulate the economy.
Government Spending: This component can influence aggregate demand and consumption.
Taxation: Can affect disposable income and subsequent consumer spending habits.
Changes in government spending and taxation can lead to changes in aggregate demand, inflation and employment rates.

Monetary Policy

Refers to actions undertaken by a central bank to control the money supply and credit conditions to stabilize the economy.
Interest rates: Manipulation of interest rates influences borrowing costs for businesses and consumers.
Reserve requirements: Regulations regarding the fraction of deposits that banks must hold in reserve.
Open market operations: Central bank buying or selling government securities to influence the money supply.

Exchange Rates

The value of one country's currency relative to another.
Fluctuations in exchange rates can affect international trade and investment, and influence the domestic price levels of imported and exported goods.

International Trade

The exchange of goods and services across national borders.
Includes imports and exports, and is often analyzed in terms of trade balances (exports minus imports).
Factors like comparative advantage, tariffs, and trade agreements influence international trade patterns and economic outcomes for participating nations.
