Individual demand vs Market demand
Individual demand refers to the quantity of a good or service that a single consumer is willing and able to purchase at a given price, while market demand represents the total quantity of a good or service that all consumers in a market are willing and able to purchase at a given price. Individual demand is specific to one consumer, whereas market demand encompasses the collective demand of all consumers in a market.

Since the market demand curve is a summation of individuals' demand curves, the special features of the individual demand curves are also applicable to the market demand. Shifts in market demand and changes in the quantity demanded by the market are defined in the same manner as for individuals. But moving to the market level intro-Consumer A Consumer Β Total Market (A -i- B) Quantity (units per time period) Figure 3.3 Adding individuáis' Demand Provides IVIarlcet Demand The market demand curve, D^, is derived by adding horizontally the individual demand curves for all consumers in the market. less—if the consumer expects that the price will increase still further. For this introductory analysis, however, the assumption is that prices are expected to remain stable. 40 Chapter Three duces further factors causing shifts in demand, namely an increase in the population and its greater total income, as well as the distribution of that income. The greater total income will usually increase demand, but the effect on different commodities will depend on how the income is distributed. Elasticity: Sensitivity to Price Changes That the quantity demanded will increase as the price of a good falls, all other things being equal, usually comes as no surprise to anyone. It is more important to know how sensitive consumers are, or how strongly they react, to a price change. The concept of elasticity is used to measure this quantitative relationship between the price change and the resulting change in quantity demanded. The general concept of elasticity is defined as the percentage change in one variable resulting from a given percentage change in another variable. Price Elasticity of Demarid The measure of the relationship of price and quantity demanded is termed price elasticity of demand.

THE DEMAND CURVE Demand is the desire of a consumer to purchase a good or service, backed by the ability to pay and the willingness to part with purchasing power to make the desire e¡ective. The demand curve is a graphic representation of the path along which the consumer would choose to purchase quantities of the good or service at various prices, other 86 PART II g KNOWING THE MARKET things being constant. The shape of the individual demand curve is based on the propo- sitions that: g The marginal utility gained from the purchase of additional quantities of a good will diminish, so that the consumer will pay a lower price for each additional unit bought. g The substitution e¡ect of a fall in price is positive, which means a consumer will switch to purchase more of a cheaper good compared with more expensive substitutes. g The income e¡ect of a fall in price makes the consumer better o¡ and enables the consumer to purchase more of everything. g The price e¡ect, which combines the substitution and income e¡ects, is normally positive, so that the demand curve slopes downward from left to right. MARKET DEMAND The market demand curve is the summation of individual demand curves and shows the quantities of a product that would be purchased by a group of consumers over a range of possible prices. The market demand curve would include all consumers who are ‘‘in the market’’, but it may be more narrowly de¢ned to include only those who are likely to purchase a product from a particular seller. The market demand curve is derived by adding horizontally all individual demand curves that are, at any given price, adding the quantity demanded by each consumer. The functional notation representation of the demand curve may be given by: Q X ¼ f ðP X Þ where Q X ¼ the quantity demanded of good X and P X ¼ the price of the good X . This function shows that the quantity demanded of good X is determined by the price of good X.

While supply curves stem from the marginal cost curves of individual producers, demand curves derive from decisions made by consumers when they decide which goods and services to buy. Demand reflects the purchases that consumers make as they strive to maximize utility, given prices and income. Demand is a technical term that describes consumer purchases, or:- Demand = consumer willingness and ability to pay for a good.
A good’s price is the most important determinant of demand, and a Demand Curve is a graphic representation commonly used to show the relationship between the price of a good and the quantity demanded of that good.- Demand Curve = a function connecting all combinations of prices and quantities consumed of a good, ceteris paribus .
9.1.1 The individual consumer’s demand curve for macaroni and cheese in Pittsburgh, Pennsylvania
The goal here is to derive an individual consumer’s demand curve. Begin by assuming that a college student in Pittsburgh has USD 40/week to spend on food. The student purchases two types of food: macaroni and cheese (Y1 ), which each initially cost USD 2/box (PY1 = USD 2/box), and pizza (Y2 ), which costs USD 5/pizza (PY2 = USD 5/pizza). Suppose that the grocery store lowers the price of macaroni and cheese from the initial price of USD 2/box to USD 1/box, and later, to USD 0.50/box. These data can be used to derive the relationship between the price of macaroni and cheese and the quantity demanded (Qd ). The data help answer the question, “How do changes in price affect the quantity demanded of a good?”The student’s budget for food is USD 40/week, so income (M) equals USD 40/week. In this case, “income” refers to the amount of money allocated to food purchases in a given time period. The following facts allow an observer to graph the consumer’s equilibrium, as shown in Figure 9.1

Chapter 10 shows how supply and demand curves interact to determine the prices and quantities of goods. The study of consumer behavior is important to producers, since consumer choices are the main determinant of profitability.9.1 Demand
