- Diminishing Marginal Utility: Describes the decrease in satisfaction a consumer experiences with each additional unit of a good consumed.
- General Economic Equilibrium: Léon Walras introduced the concept of general economic equilibrium.
- Ceteris Paribus: Assumes all other factors remain constant while examining the relationship between two variables in economic analysis.
Opportunity Cost
- Opportunity Cost: The cost of choosing one alternative over another, measured by the value of the best forgone alternative.
- Diminishing Returns: Diminishing returns in production are an example of the opportunity cost principle.
Scope of Neoclassical Economics
- Neoclassical Economics: Focuses on individual choice, the interaction of supply and demand, and optimal resource allocation in markets.
- Tariffs: The economist David Ricardo's theory primarily discusses the destabilizing effects of tariffs on trade.
Demand and Supply
- Law of Demand: The law of demand states that as the price of a good increases, the quantity demanded decreases, ceteris paribus.
- Centrally Planned Economy: A centrally planned economy features central planning and aims for a classless society.
- Perfectly Competitive Market: Buyers and sellers are price-takers in a perfectly competitive market.
- Opportunity Cost Example: Choosing to go to college instead of working full-time, the opportunity cost is the potential lost wages.
Determinants of Demand
- Number of Buyers: An increase in the number of buyers leads to an increase in the quantity demanded.
- Substitute Good Price Increase: A rise in the price of a substitute good typically leads to a rise in the quantity demanded of the original good.
- Capitalism: One key characteristic of capitalism is private ownership of capital goods and resources.
Scarcity and Economic Incentives
- Scarcity: The fundamental economic problem of scarcity refers to the limited availability of resources relative to the unlimited wants and needs of people.
- Economic Incentives: The prospect of reward motivates people to act according to economic incentives.
- Law of Supply: The law of supply states that as the price of a good rises, the quantity supplied increases, ceteris paribus.
Determinants of Supply

Ten Principles of Economics
How to make decisions
- People face tradeoffs: Choosing between efficiency and equality, with more equality potentially leading to reduced incentives for work and production.
- The cost of something is what you give up to get it: Understanding the opportunity cost associated with every choice.
- Rational people think at the margin: Understanding the incremental value of an additional unit of a good or service.
- People respond to incentives: People react to potential rewards.
How people interact
- Trade can make everyone better off: Specialization and exchange benefit all parties involved in a trade.
- Markets are usually a good way to organize economic activity: Free markets help determine what, how, how much, and for whom goods are produced.
- Governments can sometimes improve market outcomes: Government intervention may be necessary to address market failures.
How the whole economy works
- A country’s standard of living depends on its productivity: Productivity (output per worker) is a key determinant of a country's economic prosperity.
- Prices rise when the government prints too much money: Inflation occurs when there is too much money in circulation.
- There is a short-run trade-off between inflation and unemployment: Policies that aim to reduce inflation can sometimes lead to increased unemployment, vice versa.

- Demand Schedule: Shows the relationship between price and quantity demanded.
- Market Demand: The total demand for all individual buyers in a market.
Demand Determinants

- Normal good: Demand increases with higher income
- Inferior good: Demand decreases with higher income
- Price of Related Goods:
- Substitute: Increased price for a substitute leads to higher demand for the good in question.
- Complement: Increased price for a complement leads to lower demand for the good in question.
- Taste: Preferences and popularity can influence demand.
- Expectations: Anticipations about future prices or product availability can influence demand.
Supply
- Quantity supplied: The amount of a good that producers are willing to offer for sale at a given price.

- Arc elasticity: Measure of responsiveness between two points on the demand or supply curve.
Values for Elasticity
- The elasticity of demand or supply can be used to predict how much quantity will change in response to a change in price or other determinants.
- Here's how the values of elasticity relate to sensitivity:
- |Ƹ| = 0, perfectly inelastic: Quantity remains the same, regardless of price changes. The curve would be vertical.
- |Ƹ| < 1: Inelastic demand or supply, meaning quantity changes less proportionally than price changes. The curve would be relatively steep.
- |Ƹ| = 1: Unitary elastic demand or supply, meaning quantity changes proportionally to price changes.
- |Ƹ| > 1: Elastic demand or supply, meaning quantity changes more proportionally than price changes. The curve would be relatively flat.
- |Ƹ| = ∞: Perfectly elastic demand or supply, meaning any change in price will lead to an infinite change in quantity. The curve would be horizontal.
Types of Elasticity
- Price Elasticity of Demand (Ed): Measures the responsiveness of quantity demanded to changes in price. Higher Ed values indicate more sensitivity to price changes.
- Price Elasticity of Supply (Es): Measures the responsiveness of quantity supplied to changes in price. Higher Es values indicate more sensitivity to price changes.
- Income Elasticity of Demand (Ey): Measures the responsiveness of quantity demanded to changes in income.
- Cross Elasticity of Demand (Exy): Measures the responsiveness of demand for one good to a change in the price of another good.
