Study Notes

Chapter 2: Foundations of Economic Theory

Basic Economic Concepts:
- Scarcity: Limited resources vs. unlimited wants.
- Opportunity Cost: The value of the next best alternative foregone.
Supply and Demand:
- Law of Demand: Inverse relationship between price and quantity demanded.
- Law of Supply: Direct relationship between price and quantity supplied.
Market Equilibrium:
- Intersection of supply and demand curves where quantity demanded equals quantity supplied.
- Changes in equilibrium due to shifts in supply/demand.

Chapter 3: Microeconomic Theory

Consumer Theory:
- Utility: Measure of satisfaction from consumption.
- Marginal Utility: Additional satisfaction from consuming one more unit.
- Budget Constraints: Limitations on consumption based on income.
Production and Costs:
- Short-run vs. long-run production.
- Diminishing Returns: Decrease in marginal product as more of one input is added.
- Fixed and Variable Costs: Costs that do not change with output vs. costs that do.

Chapter 4: Market Structures

Perfect Competition:
- Many buyers and sellers, homogeneous products, free entry/exit.
- Firms are price takers; economic profits are zero in the long run.
Monopoly:
- Single seller, unique product, high barriers to entry.
- Price maker; can influence market prices and maximize profits.
Oligopoly:
- Few sellers, interdependent pricing, barriers to entry.
- Potential for collusion or competition; use of game theory in decision-making.

Chapter 5: Macroeconomic Theory

Economic Indicators:
- GDP: Total monetary value of all finished goods and services produced.
- Unemployment Rate: Percentage of labor force that is unemployed.
- Inflation Rate: Rate at which the general price level rises.
Monetary and Fiscal Policy:
- Monetary Policy: Central bank actions to influence money supply and interest rates.
- Fiscal Policy: Government spending and tax policies to influence economic conditions.

Chapter 6: International Economics

Trade Theories:
- Comparative Advantage: Countries should specialize in production where they have the lowest opportunity cost.
- Absolute Advantage: Ability to produce more of a good than another country with the same resources.
Exchange Rates:
- The price of one country's currency in terms of another.
- Factors affecting exchange rates: interest rates, inflation, economic stability.
Trade Policies:
- Tariffs: Taxes on imported goods to protect domestic industries.
- Quotas: Limits on the amount of imports allowed.

These chapters collectively form the foundation for understanding economic theory at both micro and macro levels, as well as international trade dynamics.

Basic Economic Concepts

Scarcity: The fundamental problem in economics, where unlimited wants clash with limited resources, forcing choices.
Opportunity Cost: The value of the next best alternative foregone when making a choice.

Supply and Demand

Law of Demand: Quantity demanded of a good decreases as its price increases, assuming all other factors remain constant.
Law of Supply: Quantity supplied of a good increases as its price increases, assuming all other factors remain constant.
Market Equilibrium: The point where the supply and demand curves intersect, representing the price and quantity where the quantity demanded equals the quantity supplied.
Shifts in Supply/Demand: Changes in factors affecting supply (e.g., input costs) or demand (e.g., consumer preferences) will shift curves, causing new equilibrium prices.

Consumer Theory

Utility: A measure of satisfaction derived from consuming a good or service.
Marginal Utility: The additional satisfaction gained from consuming one more unit of a good or service.
Budget Constraints: The limitations on consumption imposed by income and prices, forcing consumers to make choices within a constrained budget.

Production and Costs

Types of Production Periods:
- Short-run: At least one factor of production is fixed, making production decisions constrained by that fixed factor.
- Long-run: All factors of production are variable, allowing for adjustments to production scale.
Diminishing Returns: As more of one input is added while other inputs remain constant, the marginal product of the variable input will eventually decline.
Types of Costs:
- Fixed Costs: Costs that do not vary with the level of output (e.g., rent).
- Variable Costs: Costs that vary with the level of output (e.g., labor).

Perfect Competition

Numerous buyers and sellers, all offering a homogeneous product with perfect substitutes.
Free entry and exit for firms into and out of the market.
Firms are price takers, meaning they cannot influence the market price as they are too small relative to the market.
Economic profits are zero in the long run as free entry and exit will drive prices down to the point where firms earn only a normal profit.

Monopoly

A market structure with only one seller, offering a unique product with no close substitutes, and entry barriers prevent other firms from entering the market.
Price makers, exercising significant influence over prices and market outcomes.
Maximize profits by producing where marginal revenue equals marginal cost.

Oligopoly

A market structure with a few dominant sellers, offering products that may be differentiated or homogeneous, and entry barriers prevent firms from easily entering.
Interdependent pricing due to the small number of firms, necessitating strategic decision-making.
Potential for collusion (secret cooperation to control prices) or competition.
Often analyzed using game theory to understand strategic interactions between firms.

Economic Indicators

Gross Domestic Product (GDP): The total monetary value of all final goods and services produced within a country's borders during a specific period (usually a year or a quarter).
Unemployment Rate: The percentage of the labor force that is actively seeking employment but currently unemployed.
Inflation Rate: The rate at which the general price level for goods and services rises over a given period, typically measured by a consumer price index (CPI).

Monetary and Fiscal Policy

Monetary Policy: Actions taken by a central bank (e.g., the Federal Reserve in the US) to influence the money supply and interest rates to achieve macroeconomic goals like price stability and economic growth.
Fiscal Policy: Government spending and tax policies used to influence economic conditions, aiming to achieve macroeconomic objectives like stimulating growth or controlling inflation.

Trade Theories

Comparative Advantage: A country should specialize in producing and exporting goods and services where it has a lower opportunity cost compared to other countries, leading to gains from trade.
Absolute Advantage: A country's ability to produce more of a good or service than another country using the same amount of resources.

Exchange Rates

The price of one country's currency expressed in terms of another country's currency.
Exchange rates are influenced by several factors, including:
- Interest Rates: Higher interest rates attract foreign investment, leading to an increase in demand for the currency and an appreciation in its value.
- Inflation: Higher inflation erodes the purchasing power of a currency, leading to a depreciation in value against currencies with lower inflation.
- Economic Stability: Strong economic growth and stability tend to strengthen a currency, while economic uncertainty and instability weaken it.

Trade Policies

Tariffs: Taxes imposed on imported goods, often used to protect domestic industries from foreign competition.
Quotas: Limits on the quantity of goods that can be imported, serving as a barrier to trade and protecting domestic producers.
