Study Notes

Economics Study Notes - General

Economics is the study of human behavior regarding scarce resources.
Economists study decision-making, including work, purchases, savings, and investments.
Economists also study how people interact, including how buyers and sellers determine price and quantity.

Economics Principles - Principles 1-4

Principle 1: People face tradeoffs. Examples include choosing between guns and butter, or between efficiency and equity.
Principle 2: The cost of something is what you give up to get it (opportunity cost).
Principle 3: Rational people think at the margin, making small adjustments to plans of action. This involves weighing marginal costs against marginal benefits.
Principle 4: People respond to incentives.

Economics Principles - Principle 5

Principle 5: Trade can make everyone better off.
Trade allows specialization, enabling countries to enjoy a wider variety of goods and services.

Economics Principles - Principle 6

Markets are a good way to organize economic activity, as they are decentralized and influence firms and households in making their decisions.
A free market maximizes quality and costs.

Economics Principles - Principle 7

Governments can sometimes improve market outcomes, but not always.
Governments may be needed to set rules about property rights or to intervene to prevent monopolies.

Economics Concepts - Macro vs. Microeconomics

Macroeconomics studies the economy as a whole (inflation, unemployment, economic growth).
Microeconomics studies how households and firms make decisions and how they interact in markets.

Economics Concepts - Market Failure

Market failure is when a market left on its own does not efficiently allocate resources.
This can occur if there is an externality (impact on a third party) or market power.

Economics Concepts - Inflation

Inflation is an increase in the overall level of prices in an economy.
Inflation is caused by factors that increase the rate of prices.

Economics Concepts - Unemployment

Society faces a short-run tradeoff between inflation and unemployment.
The business cycle refers to the irregular, unpredictable fluctuations in economic activity.

Economics Chapter 2, Thinking Like An Economist

Economics uses observations and data like physics.
Economists use models and theories to explain observations.
Economists often cannot conduct experiments and must rely on observation.

Economic Concepts- General Assumptions

Economists use assumptions to simplify their models, to reach relevant information.
Assumptions are used to focus on the core elements of any given model or theory.

Economics Chapter 4 - Markets

Supply and demand are the forces that determine prices and quantities in market economies.
The law of demand states that prices and quantities are inversely related
The law of supply states that prices and quantities are directly related
Markets can be highly organized (e.g., agricultural markets) or less organized (local shops)
The behavior of buyers and sellers determines market price and quantity.

Economics Chapter 5: Elasticity of Demand

Elasticity is the responsiveness of quantity demanded or quantity supplied to a change in some determinant.
A measure of how much buyers and sellers respond to changes in market conditions
Total revenue is the amount buyers pay and received by sellers

Economics Chapter 5 (Continued): Elasticity of Demand (Continued)

Demand can be elastic, inelastic, or unit elastic.
The elasticity of demand depends on the availability of substitutes, the time horizon, and whether goods are necessities or luxuries.

Economics Principles - Chapter 6 (Government Policies)

Price control regulations (price ceilings and price floors) can cause distortions in a market system
Price ceilings cause shortages
Price floors cause surpluses

Economics Chapter 7 - Consumers, Producers, and Welfare Economics

Welfare economics examines how well-being is affected by resource allocation
Consumer surplus is the difference between the willingness-to-pay and the market price for a good.
Producer surplus is the difference between the market price and cost of production to a seller.
Market efficiency refers to the value of allocating in a market

Economics Chapter 8 - Costs of Taxation

The cost of a tax is not exactly the same as the loss in consumer and producer surplus
Tax revenues can be larger or smaller, depending on the size of the tax
Economic loss is a deadweight loss of the tax
The size of the tax affects the consumer surplus and producer surplus

Economics Chapter 9- Self Read

No specific concepts were found that need to be noted

Economics Chapter 10 - Externalities

Externalities are uncompensated impacts of one person's actions on the well-being of a bystander
Externalities can be negative or positive
Negative externalities can be reduced by regulations that directly command and control behavior.
Market solutions (negative externalities) can include taxes that will address incentives to decrease external costs

Economics Chapter 11 - Positive Externalities

Positive externalities can be addressed with subsidies or quantity instruments (e.g. permits).
The correct allocation is where social benefit = social cost

Economics Chapter 12 - Economic Costs and Firm Behavior

Industrial organization studies how firms make decisions regarding market conditions.
Firms aim to maximize profits
Costs are categorized as implicit and explicit.

Economics Chapter 13: Costs of Production

Firms study how they make decisions based on pricing and quantity
Decisions can be based on perfect competition, monopolistic competition, oligopoly, or monopoly.
Decisions based on profit maximization
Explicit costs are monetary payments by firm.
Implicit costs are not monetary payments or foregone opportunities
Production function is a relationship between inputs and outputs.
Marginal products are the rate at which output increases with extra input of one unit.
Diminishing marginal product- If input increases, output falls

Economics Chapter 14 - Firms in the Competitive Market

Competitive markets are widespread.
In a competitive market there are many buyers and sellers.
Firms in competitive markets are price takers. The firm must take market price.
Firms must produce at the level where Price = Marginal Cost.
Firms can decide to shut down or exit (long-run)

Economics Chapter 17 - Oligopoly

Oligopoly is a market structure with a few sellers who offer similar or identical products.
Game theory is the study of how people behave in strategic situations in the presence of others.
Nash Equilibrium - dominant strategy.
Players make choices based on what other players do
