Total Production (TP)

Total Production (TP) refers to the total quantity of output produced by a firm with the help of a given quantity of inputs during a particular period. In production analysis, especially in the short run, some factors of production are fixed while at least one factor is variable. Total production shows the overall output obtained by combining the fixed factors with different quantities of the variable factor. For example, land and machinery may remain fixed while the number of workers is increased. The total quantity produced by all the workers together represents total production.

Total production is an important concept for understanding the relationship between input and output. It helps a producer determine how much output can be obtained by employing different quantities of a variable factor. It also provides the basis for calculating marginal production and average production.

Example of Total Production

Suppose a farmer has a fixed area of land and increases the number of workers employed on that land. One worker may produce 15 bags of wheat, two workers may produce 35 bags, three workers may produce 60 bags, and four workers may produce 80 bags. The output corresponding to each number of workers represents total production.

Initially, additional workers may significantly increase output because the available land is being utilized more effectively. However, after a certain point, additional workers may contribute smaller increases because the land remains fixed.

Formula

The basic representation of total production is:

TP = Total Output

If labour is the variable factor:

TP = Quantity of output produced by all workers

For example, if one worker produces 10 units, two workers produce 25 units, and three workers produce 42 units, the total production with three workers is 42 units.

Total Production Schedule

A total production schedule shows the relationship between the quantity of variable input and the resulting total output. Consider the following example:

The table shows that total production initially increases rapidly. It continues to increase but at a declining rate after a certain stage. At seven workers, total production reaches its maximum level of 70 units. When the eighth worker is employed, total production falls to 66 units.

Stages of Total Production

Stage 1.  Increasing Returns

In the first stage, Total Production (TP) increases at an increasing rate as more units of the variable factor are employed. Marginal Production (MP) rises and Average Production (AP) also increases. This occurs because fixed factors are initially underutilized, allowing additional workers to improve their use. Specialization, division of labour, and better coordination also increase productivity. For example, adding workers to a small farm may significantly increase agricultural output during the initial production stage.

Stage 2. Diminishing Returns

In the second stage, Total Production continues to increase, but at a decreasing rate. Marginal Production starts declining but remains positive, while Average Production eventually begins to fall. This happens because the variable factor becomes relatively large compared with fixed factors. Consequently, additional workers contribute smaller additions to output. This stage is generally considered the rational stage of production, because resources are used more effectively and total output continues to increase.

Stage 3. Negative Returns

In the third stage, Total Production begins to decline as additional units of the variable factor are employed. Marginal Production becomes negative, meaning that an additional unit of input actually reduces total output. Excessive use of the variable factor creates congestion, overcrowding, and inefficient utilization of fixed resources. For example, employing too many workers on a fixed-size farm may interfere with one another and reduce agricultural output. Therefore, this stage represents inefficient production.

Importance of Total Production

The table shows that MP initially increases from 10 to 17 units. It then begins to decline. At seven workers, MP becomes zero. With the eighth worker, MP becomes negative.=

Stages of Marginal Production

Stage 1. Increasing Marginal Production

In the first stage, Marginal Production (MP) increases as additional units of the variable factor are employed. This occurs because fixed factors are initially underutilized, and additional variable inputs improve their utilization. Specialization, division of labour, better coordination, and efficient use of machinery can increase the contribution of each additional unit. For example, when workers are added to a factory with unused machines, each new worker may contribute more output than the previous worker. MP therefore rises during this stage.

Stage 2. Maximum Marginal Production

Marginal production reaches its maximum level after increasing for some time. At this point, the additional unit of the variable factor makes the highest contribution to total output. Beyond this point, the fixed factors become relatively scarce compared with the variable factor. Therefore, although total production may continue to increase, MP begins to decline. This stage represents the turning point between increasing and diminishing marginal productivity and is important for analyzing efficient input utilization.

Stage 3. Diminishing Marginal Production

In the next stage, Marginal Production declines but remains positive. Each additional unit of the variable factor adds less to total production than the preceding unit. This happens because fixed factors become increasingly insufficient relative to the growing variable factor. For example, if factory space remains fixed while more workers are continuously employed, workers may have to share machines and workspace. As a result, additional workers contribute progressively smaller amounts of output. This reflects the Law of Diminishing Marginal Returns.

Stage 4. Zero Marginal Production

Marginal production becomes zero when an additional unit of the variable factor does not increase total production. At this point, total production reaches its maximum level. For example, if seven workers produce 70 units and eight workers also produce 70 units, the marginal production of the eighth worker is zero. This point is significant because employing additional inputs beyond this level may no longer increase output and may lead to inefficient resource utilization.

Stage 5. Negative Marginal Production

In the final stage, marginal production becomes negative, meaning that the employment of an additional unit of the variable factor causes total production to decline. This occurs when the variable factor is used excessively relative to fixed factors. Overcrowding, interference among workers, and inefficient use of machinery may reduce output. For example, if seven workers produce 70 units but eight workers produce only 66 units, the marginal production of the eighth worker is −4 units. This represents an inefficient stage of production.

Importance of Marginal Production

1. Helps in Input Decisions

Marginal production helps firms determine whether employing an additional unit of variable input is useful. By measuring the extra output generated by an additional worker or resource, managers can evaluate the benefit of increasing input usage. For example, a factory can compare the additional output created by hiring another worker with the additional wage cost. This supports rational employment and production decisions and helps businesses avoid unnecessary use of resources.

2. Supports Resource Allocation

Marginal production is useful for efficient allocation of scarce resources. Businesses have limited labour, capital, raw materials, and other productive resources. By examining the additional output generated from different inputs, producers can direct resources toward activities where their marginal contribution is higher. This can improve overall productivity. For example, a firm may allocate additional workers to a production department where their marginal contribution to output is relatively greater.

3. Helps Understand Diminishing Returns

Marginal production provides the basis for understanding the Law of Diminishing Marginal Returns. Initially, MP may increase because fixed resources are better utilized. After a certain point, MP begins to decline as more variable inputs are combined with fixed factors. This information helps producers recognize when additional input is becoming less productive. Understanding diminishing returns is essential for determining appropriate production levels and avoiding excessive employment of variable resources.

4. Assists Production Planning

Marginal production plays an important role in production planning. Managers can study the additional output associated with different quantities of variable inputs and establish suitable production targets. This helps firms determine the amount of labour or other resources required to achieve a desired level of output. For example, a manufacturing company can use MP information to estimate whether adding workers will provide enough additional production to meet an expected increase in market demand.

5. Helps in Cost Control

Marginal production supports cost control by helping firms evaluate the productivity of additional inputs. If an additional worker contributes only a small amount of output while generating a significant additional cost, employing that worker may reduce efficiency. Therefore, managers can compare marginal production with the cost of additional inputs. This analysis helps businesses control unnecessary expenses, improve productivity, and maintain efficient production operations.

6. Supports Profit Maximization

Marginal production is important for profit maximization because additional inputs should be employed only when their economic contribution justifies their cost. Firms can compare the additional output generated by an input with the revenue obtained from that output and the cost of employing the input. This helps determine economically appropriate input levels. Thus, marginal production provides an important foundation for analyzing the relationship between input costs, output, revenue, and profit.

7. Helps Determine Efficient Production

Marginal production helps identify whether a firm is operating with efficient input utilization. Increasing MP indicates that additional inputs are becoming more productive, while declining MP indicates diminishing productivity. Negative MP indicates excessive use of the variable factor. By monitoring these changes, managers can adjust input levels and avoid inefficient production conditions. This contributes to better utilization of fixed resources and improves the overall efficiency of business operations.

8. Useful for Managerial Decision-Making

Marginal production provides valuable information for managerial decision-making concerning employment, expansion, production levels, and resource utilization. Managers can use MP alongside average production, total production, costs, prices, and revenue to evaluate alternative production choices. For example, before expanding a production unit, a business can examine whether additional labour and capital are likely to generate sufficient additional output. Therefore, MP is an important tool for rational and economically informed business decisions.

Average Production (AP)

Average Production (AP), also called Average Product, refers to the amount of output produced per unit of the variable factor employed in production. It measures the average productivity or efficiency of the variable input. When labour is considered the variable factor, average production shows the average output produced by each worker.

Average production is especially useful in short-run production analysis, where one factor varies while other factors remain fixed. By calculating AP, a firm can determine whether the average productivity of its variable input is increasing or decreasing.

For example, if 5 workers produce 100 units of output, average production is 20 units per worker.

Formula

The basic formula is:

AP = Total Production / Quantity of Variable Input

When labour is the variable factor:

AP = TP / L

For example, if total production is 120 units and 6 workers are employed:

AP = 120 / 6 = 20 units per worker

Therefore, each worker produces an average of 20 units.

Average Production Schedule

Consider the following example:

The table shows that average production initially increases. It reaches its maximum around the third or fourth unit of labour and then starts declining.

Increasing Average Production

Average production increases when the total production increases proportionately faster than the quantity of variable input. In the initial stage, fixed factors may be underutilized. The addition of more workers can improve specialization, coordination, and utilization of machinery.

For example, if one worker produces 10 units, two workers produce 25 units, and three workers produce 42 units, AP increases from 10 units to 12.5 units and then to 14 units per worker.

Stages of Average Production (AP)

Elasticity of Demand is an important concept in Business Economics that explains the degree of responsiveness of quantity demanded to changes in its determining factors. Consumers may change their purchases when there is a change in the price of a commodity, income of consumers, or prices of related goods. Elasticity measures the extent to which demand responds to such changes. It helps businesses understand consumer sensitivity and make appropriate economic decisions.

There are three major types of elasticity of demand: Price Elasticity of Demand, Income Elasticity of Demand, and Cross Elasticity of Demand. Price elasticity measures the response of quantity demanded to changes in price. Income elasticity measures the response of demand to changes in consumer income. Cross elasticity measures the response in demand for one product due to a change in the price of another related product.

The concept is highly useful in pricing decisions, revenue planning, demand forecasting, production planning, taxation policies, and market analysis. Understanding elasticity enables firms to predict changes in sales and revenue and develop suitable business strategies according to changing market conditions and consumer behaviour.

Importance of Various Elasticity of Demand

1. Importance of Price Elasticity of Demand

Price Elasticity of Demand measures the responsiveness of quantity demanded to a change in the price of a commodity. It is important for pricing decisions, because firms can understand how sales may respond to price changes. It also helps in revenue planning, taxation decisions, and determining suitable pricing strategies. When demand is elastic, consumers respond strongly to price changes, while inelastic demand indicates relatively smaller quantity responses. Thus, price elasticity is useful for both businesses and governments in economic decision-making.

2. Importance of Income Elasticity of Demand

Income Elasticity of Demand measures the change in quantity demanded resulting from a change in consumer income. It is important for understanding how demand for different products changes as consumer purchasing power changes. Businesses use income elasticity for demand forecasting, production planning, and market expansion decisions. It also helps classify goods as normal, inferior, or luxury goods. A firm can use this information to identify products likely to experience increased demand when incomes rise and adjust its business plans accordingly.

3. Importance of Cross Elasticity of Demand

Cross Elasticity of Demand measures the responsiveness of demand for one commodity to a change in the price of another commodity. It is particularly useful for identifying the relationship between substitute and complementary goods. Businesses use cross elasticity to understand competitive relationships and evaluate the effects of competitors’ price changes. Positive cross elasticity generally indicates substitutes, while negative cross elasticity indicates complementary goods. This information helps firms formulate pricing policies, competitive strategies, product positioning, and marketing decisions.

4. Importance in Pricing Decisions

Different types of elasticity of demand provide valuable information for determining appropriate prices. Price elasticity shows how strongly consumers respond to price changes, while cross elasticity indicates how competitors or related products may influence demand. Income elasticity provides information about changes in purchasing power and product demand. By considering these elasticity measures, businesses can develop more informed pricing strategies. They can estimate possible changes in sales and revenue and adjust prices according to market conditions and consumer responsiveness.

5. Importance in Revenue Planning

Elasticity of demand plays an important role in total revenue analysis. Price elasticity helps businesses understand whether changing prices may increase or decrease revenue. With elastic demand, quantity demanded may respond substantially to a price change, whereas with inelastic demand, the response may be relatively smaller. Income and cross elasticities also help firms anticipate revenue changes caused by changing consumer incomes and prices of related products. Therefore, elasticity analysis supports sales forecasting, revenue planning, and financial decision-making.

6. Importance in Demand Forecasting

Various elasticity measures are useful for demand forecasting because they help businesses estimate how demand may change when important economic variables change. Price elasticity helps forecast the effect of price changes, income elasticity helps estimate changes resulting from income variations, and cross elasticity helps predict demand changes caused by changes in related products’ prices. By using these relationships, firms can make better decisions regarding production, inventory, sales targets, capacity planning, and marketing activities.

7. Importance in Government Taxation Policies

Elasticity of demand is important for governments when designing taxation policies. Goods with relatively inelastic demand may experience a smaller reduction in quantity demanded after a price increase caused by taxation. Therefore, elasticity can influence the expected effect of indirect taxes on consumer demand, government revenue, and market activity. The government can also use elasticity information to study how taxation may affect different markets. However, actual tax outcomes depend on several factors, including supply conditions and market structure.

8. Importance in Business Planning and Strategy

The study of various elasticity measures supports broader business planning and strategic decision-making. Firms can use elasticity information to understand consumer sensitivity, competitive relationships, income-related demand changes, and potential revenue effects. Price elasticity supports pricing decisions, income elasticity assists market planning, and cross elasticity helps analyse substitutes and complements. Together, these measures provide businesses with a better understanding of market demand and consumer behaviour, helping them develop production, marketing, pricing, and expansion plans based on economic conditions.

9. Importance in Production Planning

Different forms of Elasticity of Demand help firms plan their production according to expected changes in market demand. Price elasticity helps estimate the effect of price changes on sales, while income elasticity indicates how demand may change with consumer income. Cross elasticity helps businesses anticipate changes caused by prices of related products. This information supports decisions regarding production volume, capacity utilization, inventory management, and resource allocation, reducing the possibility of overproduction or shortages.

10. Importance in Market and Competitive Analysis

Elasticity of demand is useful for understanding market conditions and competitive behaviour. Cross elasticity helps firms identify substitute and complementary products and assess the relationship between competing goods. Price elasticity indicates the sensitivity of customers to changes in prices, while income elasticity provides insights into changing purchasing power. These measures help businesses evaluate competitive pressures, market opportunities, consumer sensitivity, and product positioning, thereby supporting effective marketing and strategic planning.

The concept of Business Economics is based on the systematic application of economic reasoning to business situations. It focuses mainly on decision-making under scarcity and uncertainty. Managers have to choose the best alternative among different options concerning production, investment, pricing, resource utilization, and expansion. Business Economics provides tools such as demand analysis, cost analysis, marginal analysis, forecasting, and optimization to support these decisions.

Meaning of Business Economics

Business Economics is also known as Managerial Economics because it provides economic knowledge for managerial decision-making. It studies how businesses can utilize limited resources efficiently to achieve objectives such as profit maximization, cost minimization, revenue growth, and business expansion. It considers both internal business factors and external economic factors, including government policies, inflation, interest rates, economic growth, and market competition.

Business Economics refers to the application of economic principles, theories, and analytical techniques to solve business problems and make effective managerial decisions. It acts as a bridge between economic theory and business practice. Business managers use economic concepts to understand demand, supply, costs, production, pricing, competition, and market conditions. The subject helps organizations make rational choices when resources are limited and business objectives need to be achieved.

Nature of Business Economics

1. Applied Nature

Business Economics has an applied and practical nature because it applies economic theories to real-world business problems. Concepts such as demand, supply, cost, revenue, production, and pricing help managers make practical decisions. It does not merely study economic principles theoretically but focuses on their application in business situations. Managers use these principles to solve problems related to resource allocation, production planning, pricing decisions, investment, and profit management. Thus, Business Economics connects economic theory with business practice.

2. Microeconomic Orientation

Business Economics mainly has a microeconomic orientation because it focuses on the behavior and decisions of individual firms, consumers, and markets. It studies factors such as demand, elasticity, production, costs, revenue, pricing, and market structure.

Efficient resource utilization can improve productivity, reduce waste, and strengthen operational efficiency.

3. Helps Understand Market Conditions

Business Economics helps managers understand changing market conditions by analyzing demand, supply, consumer behavior, competition, and market structures. Such knowledge enables firms to identify market opportunities and recognize factors that may influence business performance. Understanding market conditions is important for decisions concerning production, pricing, marketing, and competitive strategies. It allows organizations to adjust their operations according to changes in customer requirements and prevailing economic circumstances.

4. Facilitates Business Forecasting

Effective business forecasting is essential for future planning, and Business Economics provides techniques for predicting possible economic and market developments. Managers can analyze historical data, consumer trends, market conditions, and economic indicators to estimate future demand, sales, costs, and revenues. Forecasting helps businesses plan production, inventory, staffing, investment, and financing requirements. Although forecasts involve uncertainty, systematic economic analysis provides useful information for preparing realistic and flexible business plans.

5. Supports Pricing and Profit Planning

Business Economics is important for determining appropriate pricing and profit strategies. Managers analyze demand elasticity, costs, competition, market structure, and revenue before establishing prices. Economic analysis also helps identify relationships between price, sales volume, revenue, and profit. This information supports decisions regarding pricing policies and output levels. By understanding these relationships, firms can develop strategies aimed at achieving organizational objectives such as profitability, revenue growth, and market development.

6. Helps Control Business Costs

Business Economics contributes to effective cost management by examining the behavior of different costs and their relationship with production. Managers analyze fixed costs, variable costs, average costs, marginal costs, and economies of scale to identify opportunities for efficiency. Understanding cost behavior helps organizations determine appropriate production levels and avoid unnecessary expenditure. Effective cost analysis can improve operational efficiency, resource utilization, and financial planning, thereby supporting sustainable business performance.

7. Assists Strategic Planning

Business Economics provides valuable support for strategic planning by helping managers evaluate both internal and external economic factors. Businesses must consider competition, inflation, interest rates, consumer demand, technology, government policies, and economic growth while developing strategies. Economic analysis helps organizations assess potential opportunities and constraints before making long-term decisions. It is therefore useful for decisions involving market expansion, investment, diversification, production capacity, and competitive positioning.

8. Helps Deal with Economic Changes

Business Economics enables organizations to respond to changes in the economic environment. Factors such as inflation, recession, interest rates, exchange rates, unemployment, and government policies can affect business operations. Economic analysis helps managers understand these influences and adjust their strategies accordingly. By monitoring economic developments, firms can make appropriate changes in pricing, production, investment, financing, and resource allocation. This helps organizations maintain effective operations under changing economic conditions.

Consumer Surplus is the difference between the price that consumers pay and the price that they are willing to pay. On a supply and demand curve, it is the area between the equilibrium price and the demand curve

For example, if you would pay 76p for a cup of tea, but can buy it for 50p; your consumer surplus is 26p

Diagram of Consumer Surplus

Producer Surplus

• This is the difference between the price a firm receives and the price it would be willing to sell it at.
• Therefore it is the difference between the supply curve and the market price.

Consumer Surplus and Marginal Utility

The demand curve is derived from our marginal utility. If the marginal utility of a good is greater than the price, then that is our consumer surplus.

• Firms can reduce consumer surplus if they have market power. This enables them to raise prices above the competitive equilibrium.
• In a monopoly, a firm will maximise profits by reducing consumer surplus.
• Another way to reduce consumer surplus is to engage in price discrimination. Charging different prices to different groups of consumers. Those with inelastic demand will see their consumer surplus reduced. More on Price discrimination. To completely eliminate consumer surplus, a firm would need to engage in first-degree price discrimination this means charging the consumer the highest price they are willing to pay.
• To gain market power, a firm could advertise to create brand loyalty, this will make demand more inelastic

Income Effect on Consumer’s Equilibrium

Income Effect on a consumer’s equilibrium refers to the change in the quantity demanded of a good or service when the consumer’s real income changes, due to a price change, while keeping preferences and the prices of other goods constant. When the price of a good decreases, the consumer’s real income effectively increases, allowing them to purchase more of that good or other goods, shifting their equilibrium. Conversely, if the price increases, real income decreases, leading to a reduced quantity demanded of the good. The income effect, together with the substitution effect, determines the overall change in demand.

Figure 1 explains the effect of change in the consumer’s income on his equilibrium level.

In figure 1, Point E is the initial equilibrium position of the consumer. At point E, the indifference curve IC₁ is tangent to the price line MN. Suppose the consumer’s income increases. This causes the budget line shifts from MN to M₁N₁ and then to M₂N₂. Consequently, the equilibrium point shifts from E to E₁ and then to E₂.

Income Consumption Curve

You can obtain income consumption curve (ICC) by joining all equilibrium points E, E₁ and E₂ as shown in figure 1. Normal goods generally have positively sloped income consumption curves, which implies that consumer’s purchases of the two commodities increases as his income increases. At the same time, this may not be applicable in all cases.

Substitution Effect on Consumer’s Equilibrium

Suppose there are two commodities, namely apple and orange. Your money income is $100, which does not change. You need to purchase apple and orange using the entire money income, i.e. $100. Assume that the price of apple increases and the price of orange decreases. What do you do in this case? You tend to buy more oranges and less apples since oranges are cheaper than apples. What exactly you are doing is that you are substituting oranges for apples. This is known as substitution effect.

The substitution effect occurs because of the following two reasons:

(a) The relative prices of commodities change. This makes one commodity cheaper and the other commodity costlier.

(b) Money income of the consumer does not change.

Figure 2 is helpful to understand the concept of substitution effect in a simple manner.

In figure 2, AB represents the original budget line. The point Q represents the original equilibrium point, where the budget line is tangent to the indifference curve. At point Q, the consumer buys OM quantity of commodity X and ON quantity of commodity Y. Assume that the price of commodity Y increases and the price of commodity X decreases. As a result, the new budget line would be B₁A₁. The new budget line is tangent to the indifference curve at point Q₁. This is the new equilibrium position of the consumer after the relative prices change.

At the new equilibrium point, the consumer has decreased the purchase of commodity Y from ON to ON₁ and increased the purchase of commodity X from OM to OM₁. However, the consumer stays on the same indifference curve. This movement along the indifference curve from Q to Q₁ is known as the substitution effect. In simple terms, the consumer substitutes one commodity (its price is less) for the other (its price is more); it is known as the ‘substitution effect.’

Price Effect on Consumer’s Equilibrium

Price Effect on a consumer’s equilibrium refers to the change in the quantity demanded of a good due to a change in its price, holding other factors constant. It consists of two components: the Substitution Effect and the Income Effect. The substitution effect occurs when a price change makes a good more or less attractive compared to other goods, leading to a change in the quantity demanded. The income effect arises when a price change alters the consumer’s real income, affecting their purchasing power. Together, these effects determine how a price change impacts consumer equilibrium.

Let us consider two commodities, namely commodity X and commodity Y. Price of commodity X changes. Price of commodity Y and consumer’s income are constant.

Suppose price of commodity X decreases. In figure 3, the decline in the price of commodity X is represented by the corresponding shifts of budget line from AB₁ to AB₂, AB₂ to AB₃ and AB₃ to AB₄. The points C₁, C₂, C₃ and C₄ denote respective equilibrium combinations. According to figure 3, consumer’s real income increases as the price of commodity X reduces. Due to an increase in the consumer’s real income, he is able to purchase more of both commodities X and Y.

Price Consumption Curve

You can derive the Price Consumption Curve (PCC) by joining all equilibrium points (in the above example, C₁, C₂, C₃ and C₄). In the above figure, the PCC has a positive slope. This means that as price of commodity X falls, the consumer’s real income increases.

Derivation of Demand Curve from Price Consumption Curve

The price consumption curve (PCC) tells us what happens to the quantity demanded when there is a change in price. A consumer’s demand curve also explains the relationship between the price and quantity demanded of a commodity. Therefore, price consumption curve is useful to derive an individual consumer’s demand curve. Though a consumer’s demand curve and his price consumption curve give us same information, the demand curve is more straightforward in what it tries to convey.

Figure 4 illustrates the process of deriving the individual consumer‘s demand curve from his price consumption curve.

In figure 4, horizontal axis measures commodity A, and vertical axis represents consumer’s money income. IC₁, IC₂, and IC₃ denote indifference curves. Suppose the price of commodity A continuously decreases. As a result, LN, LQ and LR are the subsequent budget lines of the consumer. Initially, P₁ is consumer’s equilibrium. At this equilibrium point, the consumer buys OM₁ quantity of commodity A.

Price of a unit of commodity A = total money income/number of the units that can be bought with that money.

Hence, at P₁ (equilibrium point – budget line is tangent to the indifference curve IC₁), the price per unit of commodity A is OL/ON. At OL/ON price, the consumer demands OM₁ quantity of commodity A.

Likewise, at OL/OQ price, the consumer is able to buy OM₂ quantity of commodity A and at OL/OR price, he buys OM₃ quantity of commodity A.

If you connect all equilibrium points (P₁, P₂ and P₃), you will be able to get the price consumption curve.

The demand curve, as mentioned above, depicts the prices and corresponding quantities of commodity purchased by the consumer.

For illustration purpose, suppose the consumer’s income is $40, ON = 8 units, OQ = 10 units and OR = 20 units. With the help of this information, you can construct a demand schedule as follows:

Table 1: Price-Demand Schedule for Commodity A

Budget Line	Price of A (in $) = Total Money Income/No. of Units of A	Quantity of A Demanded
LN	OL/ON (40/8 = 5)	OM1 = 8 units
LQ	OL/OQ (40/10 = 4)	OM2 = 10 units
LR	OL/OR (40/20 = 2)	OM3 = 20 units

Once you have the demand schedule, you can derive an individual consumer’s demand curve as shown in figure 5.

Figure 5 illustrates a consumer’s demand curve. If you need to construct a market demand curve, it will be possible by a horizontal summation of individual demand curves.
