Demand theory forms the basis for the demand curve, which relates consumer desire to the amount of goods available. As more of a good or service is available, demand drops and so does the equilibrium price. Demand theory highlights the role that demand plays in price formation, while supply-side theory favors the role of supply in the market. Demand is simply the quantity of a good or service that consumers are willing and able to buy at a given price in a given time period.

Demand theory is one of the core theories of microeconomics. It aims to answer basic questions about how badly people want things, and how demand is impacted by income levels and satisfaction utility. Based on the perceived utility of goods and services by consumers, companies adjust the supply available and the prices charged.

Built into demand are factors such as consumer preferences, tastes, choices, etc. Evaluating demand in an economy is, therefore, one of the most important decision-making variables that a business must analyze if it is to survive and grow in a competitive market. The market system is governed by the laws of supply and demand, which determine the prices of goods and services.

When supply equals demand, prices are said to be in a state of equilibrium. When demand is higher than supply, prices increase to reflect scarcity. Conversely, when demand is lower than supply, prices fall due to the surplus. The law of demand introduces an inverse relationship between price and demand for a good or service. It simply states that as the price of a commodity increases, demand decreases, provided other factors remain constant.

This relationship can be illustrated graphically using a tool known as the demand curve. The demand curve has a negative slope as it charts downward from left to right to reflect the inverse relationship between the price of an item and the quantity demanded over a period of time. An expansion or contraction of demand occurs as a result of the income effect or substitution effect. In this case, the consumer can purchase more of the goods on a given budget.

This is the income effect. As more people buy the good with the lower price, demand increases. Sometimes, consumers buy more or less of a good or service due to factors other than price. This is referred to as a change in demand. For example, a consumer who receives an income raise at work will have more disposable income to spend on goods in the markets, regardless of whether prices fall, leading to a shift to the right of the demand curve.

The law of demand is violated when dealing with Giffen or inferior goods. Giffen goods are inferior goods that people consume more of as prices rise, and vice versa. Since a Giffen good does not have easily available substitutes, the income effect dominates the substitution effect. When demand exceeds supply, prices tend to rise. If there is a decrease in supply of goods and services while demand remains the same, prices tend to rise to a higher equilibrium price and a lower quantity of goods and services.

However, when demand increases and supply remains the same, the higher demand leads to a higher equilibrium price and vice versa. Supply and demand rise and fall until an equilibrium price is reached. Behavioral Economics. Your Privacy Rights. To change or withdraw your consent choices for Investopedia.

Economics Microeconomics. What Is Demand Theory? Key Takeaways Demand theory describes the way that changes in the quantity of a good or service demanded by consumers affects its price in the market, The theory states that the higher the price of a product is, all else equal, the less of it will be demanded, inferring a downward sloping demand curve.

Likewise, the more demand that occurs, the greater the price will be for a given supply. Demand theory places primacy on the demand side of the supply-demand relationship. Compare Accounts.

Related Terms Law of Supply and Demand Definition The law of supply and demand explains the interaction between the supply of and demand for a resource, and the effect on its price. Quantity Supplied The quantity supplied is a term used in economics to describe the amount of goods or services that are supplied at a given market price.

Quantity Demanded Quantity demanded is used in economics to describe the total amount of a good or service that consumers demand over a given period of time. Substitution Effect Definition The substitution effect is the decrease in a product's sales attributed to consumers switching to cheaper alternatives when its price rises. Consumer Surplus Definition A consumer surplus occurs when the price that consumers pay for a product or service is less than the price they're willing to pay.

Theory of Demand

The relationship between income and expenditure is often called a consumption schedule. It is used to describe economic trends in the household sector. When there is more money or anticipation of income, more goods are purchased by consumers. Meaning money is spent on expenditures, at times, even if there isn't enough income to cover them. This is a common economic principal used to describe spending trends for national and world economies.

The Relationship Between Income & Expenditure

The paper proposes a simple utility function that can generate Giffen behaviour. The function suggests an alternative direction where Giffen behaviour can be found and also implies a convenient framework for empirical testing. Moreover, because of its simple form, the utility function is well-suited for teaching purposes. It was not until the third [ 1 , 2 ] edition of his Principles that Alfred Marshall stated that the law of demand may not always hold.

In economics and particularly in consumer choice theory , the substitution effect is one component of the effect of a change in the price of a good upon the amount of that good demanded by a consumer, the other being the income effect. When a good's price decreases, if hypothetically the same consumption bundle were to be retained, income would be freed up which could be spent on a combination of more of each of the goods. Thus the new total consumption bundle chosen, compared to the old one, reflects both the effect of the changed relative prices of the two goods one unit of one good can now be traded for a different quantity of the other good than before as the ratio of their prices has changed and the effect of the freed-up income. The effect of the relative price change is called the substitution effect , while the effect due to income having been freed up is called the income effect. If income is altered in response to the price change such that a new budget line is drawn passing through the old consumption bundle but with the slope determined by the new prices and the consumer's optimal choice is on this budget line, the resulting change in consumption is called the Slutsky substitution effect.

Aggregate supply is the money value of total output available in the economy for purchase during a given period. When expressed in physical terms, aggregate supply refers to the total output of goods and services produced for sale by all the entrepreneurs in an economy. It is assumed that in short-run, prices of goods do not change and elasticity of supply is infinite. At the given price level, output can be increased till all the resources are fully employed. If we go deep, we will find aggregate supply is represented by national income.
