Microeconomics Overview and Key Concepts

Study Notes

Microeconomics

Microeconomics focuses on the behavior of individual economic agents, like consumers, firms, and markets.
It examines how these agents make decisions in the face of scarcity.
Key concepts include supply and demand, elasticity, production, cost, and market structures.
Supply and demand curves illustrate the relationship between price and quantity supplied and demanded.
Elasticity measures the responsiveness of quantity demanded or supplied to changes in price.
Production functions describe the relationship between inputs and output.
Costs of production include fixed costs, variable costs, and total costs.
Market structures include perfect competition, monopoly, oligopoly, and monopolistic competition, each with varying degrees of competition and market power.
Decisions made by individual agents, in relation to supply and price, determine market equilibrium.

Macroeconomics

Macroeconomics studies the overall performance of the economy.
It examines aggregate variables such as GDP, inflation, unemployment, and interest rates.
Key macro goals include sustained economic growth, low unemployment, price stability, and balanced trade.
Gross Domestic Product (GDP) measures the total value of goods and services produced in a country.
Inflation refers to a sustained increase in the general price level of goods and services.
Unemployment represents the portion of the labor force that is actively seeking employment but unable to find it.
Money supply and interest rates are crucial determinants in macroeconomics, influencing economic activity.
Fiscal policy, involving government spending and taxation, can influence aggregate demand.
Monetary policy, controlled by central banks, manages money supply and interest rates.

Economic Systems

Different economic systems exist in the world, each with its own approach to resource allocation and distribution.
Capitalism prioritizes private ownership, free markets, and competition, leading to market-determined prices and production.
Socialism emphasizes collective ownership and control of resources, central planning, and distribution according to social needs.
Mixed economies combine elements of both capitalism and socialism to varying degrees.
Each system has advantages and disadvantages, affecting efficiency, equity, and growth rates.

Economic Growth

Economic growth is an increase in real GDP or per capita GDP over a period.
Factors contributing to growth are capital accumulation, technological progress, improved education, human capital, and institutional quality.
Technological advancements significantly drive long-term economic growth by increasing efficiency and productivity.
Investment in physical and human capital contributes to a more productive workforce and economy.
Improvements in institutions, such as the rule of law and property rights, encourage investment and economic activity.

Economic Development

Economic development goes beyond growth, encompassing improvements in living standards, poverty reduction, and broader social progress.
Crucial elements involve factors like infrastructure, education, health, and technology.
Countries seek strategies tailored to their specific circumstances, including strategies for poverty reduction, improving infrastructure and skills, and promoting economic growth.
Challenges in development include issues like inequality, corruption, and environmental concerns.

International Economics

International economics studies economic interactions between countries.
It involves trade, capital flows, and exchange rates.
Trade involves the exchange of goods and services between countries, potentially increasing consumption and welfare.
Capital flows include investments and borrowing between countries, promoting growth and efficiency.
Exchange rates determine the value of one currency relative to another, influencing trade and investment.
Comparative advantage describes the ability of a country to produce a good or service at a lower opportunity cost compared to other countries, potentially leading to specialization and gains from trade.
