Production Analysis Class 11 Notes AP Inter 1st Year Economics 4th Lesson
→ Production: Production is the process that converts inputs into output.
→ Production function: Production function shows the relationship between inputs and output produced by the firm.
→ Factors of production: Factors that help in the production process are called factors of production. For example, land, labour, capital and organization.
→ Short period: Short period is a period in which a producer is unable to change factors of production to increase output.

→ Long period: Long period is a period in which factors of production can be change by the producer to increase output.
→ Average product: Average product can be obtained by dividing total product by the number of labourers.
→ Marginal product: Marginal product is the additional product by employing an additional labour.
→ Fixed factors: Fixed factors are those factors which cannot be changed by the producer in the short period. Ex: Buildings, machinery etc.
→ Variable factors: Variable factors are those factors which can be change by the producer in the short period. Ex: Labour, raw material etc. In long run all factors are variable factors.
→ Change in scale of production: Change in all inputs in the same proportions.
→ Internal economies: Internal economies refers that when a firm expands output by increasing all inputs and gets certain advantages.
→ External economies: External economies are those economies which accrue to all firms as a result of the expansion of industry as a whole.
→ Supply: Supply is the quantity of good offered by the producer for sale at different prices during a certain period.
→ Supply function: Supply function shows the relationship between the supply and the factors of production of a good.
→ Elasticity of Supply: The responsiveness of supply due to change in its price.
→ Isoquant: The set of all possible combinations of inputs that yield the same level of output.

→ Production means creation of goods.
→ The factors which participate in production process are known as factors of production. They are
- Land
- Labour
- Capital
- Organisation.
→ Production function explains the physical relationship between inputs and outputs.
→ Short period production function also known as the law of variable proportions. It explains the changes in output when a factor of production is varied while keeping other factors constant. In this processes three stages of returns will take place.
- Increasing returns
- Diminishing returns
- Negative returns.
→ Long period production function also known as the law of returns to scale. In the long period while increasing all the factors of production, how to change the output. The output varied in three ways.
- Increasing returns to scale
- Constant returns to scale
- Diminishing returns to scale
→ Internal economies are those economies which are open to an individual firm when its size expands.
→ External economies are those economies which are open to all the firms or to an industry when its size expands.

→ The quantity of a commodity that a seller is prepared to sell at a particular price and at a particular time.
→ The amount of expenditure incurred by producing a commodity. There are different cost curves in short run and long run. They are fixed cost, variable cost, total cost, average cost, margin cost etc.
→ The proceeds or receipts that a firm gets from the sale of its product is called revenue. They are three types.
- Total revenue
- Average revenue
- Marginal revenue
→ The term factors of production refers to all those individuals, agents, materials, machines, inputs, etc. which participate and which help in the production of various goods and services.
→ The four factors of production in Economics are land, labour, capital and organisation.
→ The physical/technical or mathematical relationship between physical quantities of inputs and physical quantities of outputs is called production function.
→ The law of variable proportions, also known as the law of diminishing returns, which applies in the short run, explains the changes in output when a factor of production, is varied or changed keeping other factors constant.
→ In the law of variable proportions, there are 3 stages of returns namely, stage of increasing returns, stage of diminishing returns and stage of negative returns.
→ The law of returns to scale, which applies in the long run, explains the changes in output when all the inputs (both fixed and variable) are changed in the long run.
→ In the law of returns to scale, there are 3 stages, namely, the stage of increasing returns to scale, the stage of constant returns to scale, the stage of diminishing returns to scale.
→ The benefits or advantages which a firm enjoys by changing its scale of production or operations from small scale to large scale are known as economies of large scale production.
→ Economies of large scale production are of 2 types, namely, a) Internal Economies and b) External Economies.
→ lnternal Economies are of 5 types, namely, Technical Economies; Managerial Economies, Marketing Economies, Financial Economies, Risk-bearing Economies.
→ External Economies of scale are of 4 types, namely, Infrastructure Economies, Specialisation Economies, Information and Marketing Economies, Research Economies.

→ The term supply refers to the quantities which a seller / business firm is willing and prepared to sell at a particular price and at a particular time.
→ various determinants of supply are price of the good, prices of related goods, prices of factors of production, state of technology, government policy, weather conditions.
→ The equation which shows the functional relationship between the determinants of supply of a good and the supply of that good is called supply function.
→ The table or schedule which shows the various quantities offered for sale at different prices is known as supply schedule.
→ The law of supply states that “other things remaining the same, the supply of a commodity extends / expands (increases) with a rise in its price and contracts (decreases) with a fall in its price.”
→ A supply curve slopes upwards from left to right, indicating that price and supply are directly related.
→ Elasticity of supply is divided into five types. They are: 1) Perfectly elastic supply (Es = ∞), 2) Perfectly inelastic supply (Es = 0), 3) Relatively elastic supply (Es > 1), 4) Relatively inelastic supply (Es < 1), 5) Unitary elasticity of supply (Es = 1).
→ The various types of expenditure incurred by a producer / business firm to produce goods is known as production cost.
→ Money, costs, real costs, opportunity costs, explicit costs, implicit costs, fixed costs, variable costs are some of the cost concepts. Average fixed cost, average variable cost, average cost, marginal cost are some of short run cost concepts.
→ The receipts or sale proceeds received by a business firm through the sale of its goods are known as total revenue. Revenue is divided into three types. They are: 1) Total revenue, 2) Average revenue, 3) Marginal revenue.
→ The revenue received on an average by a business firm from the sale of each unit is known as average revenue. The additional or extra revenue received from the sale of an additional unit of the good is known as marginal revenue.

→ In perfect competition, average revenue and marginal revenue curves are parallel to X – axis.
→ In imperfect competition, average revenue curve and marginal revenue curves slope downwards from left to right.
→ The costs which remain fixed and which do not change with a change in output are known as fixed costs.
→ The costs which change with a change in direct proportion to a change in output or quantity produced are called variable costs.
→ Production is very important economic activity.
→ In Economics, the word production is used in a wider sense. Production defined as creation or addition of utility.
→ The term factors of production refers to all those individuals, agents, materials, machines, inputs etc., which participate and which help in the production of various goods and services.
→ The four factors of production in Economics are land, labour, capital and organisation.
→ In Economic terms Land does not mean soil or earth’s surface alone but refers to all free gifts of nature.
→ In Economics, Labour is used a wider sense. Any work whether manual or mental which is undertaken for a monetary consideration is called labour.
→ Capital is man-made and is rightly defined as “produced means of production.”
→ Increase in the stock of real capital in a country is called capital formation.
→ According to Schumpeter, the true function of an entrepreneur is to introduce innovations. Entrepreneur is the person who prepared to bear the risk.
→ The factors of production or inputs are classified in fixed and variable.
→ “Production function is the name given to the relationship between rates of inputs of productive services and the rate of output of product – Stigler.
→ ∴ Qx =f(a, b, c, d, …………..n). It is a mathematical firm of production function.
→ ∴ Q= AKa Lb is a Cobb-Douglas production function.
→ The short term production function of a firm is studied by the law of variable proportion. This law is also known as the Law of Diminishing Returns.

→ Abbreviations:
TP= Total Product
AP = Average Product
MP = Marginal Product
→ The law of variable proportion is very crucial concept which helps the producer to produce to an optimal level.
→ Long-run behaviour output is studied under the law of returns to scale of the law of fixed proportions.
→ Understanding the law of return’s to scale helps businesses to determine the optimal production level by identifying when to expand operations and capitalise on economics of scale.
→ Internal economies are those which are open to a single factory or a single firm independently of the action of other firms.
→ An Isoquant is the set of all possible combinations of the two inputs that yield the same maximum possible level of output.
→ Qx= f(Px, Py, Pf , T,G,O)
= Supply function
→ Price elasticity of Supply = \(\frac{\text { Percentage change in quantity supplied }}{\text { Percentage change in price }}\)
= \(\frac{\Delta Q}{\Delta P} \times \frac{P}{Q}\)
→ ఉత్పత్తి అనగా ప్రయోజనాల సృష్టి.
→ ఉత్పత్తిలో పాల్గొనే కారకాలను ఉత్పత్తి కారకాలంటారు. అది నాలుగు
- భూమి.
- శ్రమ.

→ స్వల్పకాలం అనగా ఉత్పత్తి ప్రక్రియలో చర సాధనాలను మాత్రమే మార్చి, ఉత్పత్తిలో మార్పులు చేపట్టగలిగే కాలపరిధి.
→ చరానుపాత సూత్రం స్వల్ప కాలానికి చెందినది. ఈ సూత్రం ప్రకారం కొన్ని ఉత్పత్తి కారకాలను స్థిరంగా ఉంచి చర ఉత్పత్తి సాధనం పరిమాణంలో మార్పు చేస్తూ ఉన్నప్పుడు ఉత్పత్తి ఏ అనుపాతంలో మారుతుందో తెలియజేస్తుంది.
→ దీర్ఘ కాలంలో అన్ని ఉత్పత్తి సాధనాలు చర అనుపాతంలో మారినపుడు ఉత్పత్తి ఏ అనుపాతంలో మార్పు చెందుతుందో తెలియజేసే దానిని తరహాననుసరించి ప్రతిఫలాలు అంటారు.

→ ఒక నిర్ణీత ధర వద్ద నిర్ణీతకాలంలో మార్కెట్లో విక్రయానికి సిద్ధంగా ఉన్న వస్తు పరిమాణాన్ని సప్లయ్ అంటారు. ఇతర పరిస్థితులు మారనంత వరకు ఒక వస్తువు ధర తగ్గితే సప్లయ్ తగ్గుతుంది. ధరపెరిగితే సప్లయ్ పెరుగుతుంది.
→ ఒక ఉత్పత్తిదారుడు ఉత్పత్తికి వెచ్చించే మొత్తాన్ని “ఉత్పత్తి వ్యయం” అంటారు. వ్యయాలు రెండు రకాలు
- సాధారణ వ్యయాలు
