1. Ceteris paribus: The law of demand assumes that all other factors affecting demand remain constant, such as prices of related goods, consumer income, consumer preferences, and external factors like weather or advertising.
2. Rational behavior: The law of demand assumes that consumers act rationally and seek to maximize their utility by purchasing goods and services that provide the most satisfaction for the price.
3. Diminishing marginal utility: The law of demand assumes that as consumers consume more of a good or service, the additional satisfaction or utility they derive from each additional unit decreases.
4. Income effect: The law of demand assumes that as the price of a good or service decreases, consumers' real income increases, allowing them to purchase more of that good or service.
5. Substitution effect: The law of demand assumes that as the price of a good or service decreases, consumers will substitute it for more expensive alternatives, leading to an increase in demand for the cheaper good or service.

Assumptions of the Law of Demand
1. Ceteris Paribus Condition: All other factors affecting demand remain constant, such as income, tastes, prices of substitutes/complements, and consumer expectations. 2. Positive Income Effect: As income increases, demand for normal goods (those whose demand increases with income) increases, and demand for inferior goods (those whose demand decreases with income) decreases. 3. Negative Substitution Effect: If the price of a substitute good increases, the demand for the original good will increase; if the price of a complement good increases, the demand for the original good will decrease. 4. Rational Consumers: Consumers make rational choices based on their preferences and available information. 5. Absence of Rationing: Goods are available to consumers in sufficient quantities, and there are no restrictions on their consumption. 6. Time Period: The law of demand is assumed to hold true in a specific time period, and may not be valid in the long run. 7. Measurement: The quantities demanded and prices are measurable and comparable. 8. No Expectations of Future Price Changes: Consumers do not anticipate any significant price changes in the future. 9. No Habit Formation: Consumers do not develop strong habits or preferences for specific goods that would influence their demand independent of their current income or prices. 10. Absence of External Factors: External factors, such as natural disasters or government policies, do not influence demand.
