Micro and Macroeconomics Overview

Study Notes

Microeconomics

Microeconomics examines the behavior of individual economic agents, such as households and firms, in making decisions in a specific market.
It focuses on factors influencing supply and demand, pricing mechanisms, and allocation of resources.
Key concepts include:
- Supply and demand: The interaction of buyers and sellers in a market to determine price and quantity.
- Elasticity: The responsiveness of quantity demanded or supplied to changes in price or other factors.
- Market structures: Different types of market organization, including perfect competition, monopoly, oligopoly, and monopolistic competition.
- Production costs: The expenses incurred by firms in producing goods and services.
- Consumer behavior: How consumers make purchasing decisions based on their preferences and budget constraints.

Macroeconomics

Macroeconomics examines the behavior of the economy as a whole.
It deals with large-scale economic issues like inflation, unemployment, economic growth, and government policies.
Key concepts include:
- Gross Domestic Product (GDP): The total value of goods and services produced within a country in a given period, a crucial indicator of economic health.
- Inflation: A general increase in the price level of goods and services over time, reducing purchasing power.
- Unemployment: The percentage of the labor force that is actively seeking work but unable to find it.
- Economic growth: An increase in real GDP over time, reflecting an improvement in living standards.
- Fiscal policy: Government spending and taxation decisions to influence the economy.
- Monetary policy: Actions taken by a central bank to manage the money supply and interest rates to control inflation and promote economic growth.

Key Schools of Economic Thought

Classical economics emphasizes free markets and limited government intervention.
Keynesian economics advocates for government intervention to manage aggregate demand and stabilize the economy during recessions.
Modern Monetary Theory (MMT) argues that governments with fiat currencies can always afford to pay their debts and that constraints on government spending are often unfounded.

Economic Systems

Command economies: Government dictates the allocation of resources and production levels.
Market economies: Individuals and firms make decisions about production and consumption.
Mixed economies: Combine elements of both command and market economies; most countries today operate under a mixed economy, with varying degrees of government intervention.

Economic Growth

Factors driving economic growth include technological advancements, investment in capital, improved education and human capital, and institutional quality.
Growth leads to increases in living standards, productivity, and innovation.

Economic Models

Models are simplified representations of complex economic phenomena.
They use mathematical equations and graphs to illustrate relationships between variables.

International Economics

International economics examines trade, exchange rates, and financial flows between countries.
Key concepts include:
- Comparative advantage: The ability of a country to produce a good or service at a lower opportunity cost than another country.
- Trade barriers: Restrictions imposed by governments on imports and exports, like tariffs and quotas.
- Exchange rates: The relative value of one currency in terms of another.
- Foreign direct investment: Investment made by a company in one country into business operations in another country.

Economic Development

Economic development focuses on improving living standards and reducing poverty in developing countries.
Key factors influencing development include access to education, healthcare, infrastructure, and technology.
