2. It describes three stages: initially increasing marginal returns, then diminishing marginal returns, and finally negative marginal returns.
3. An example is given of a farmer using increasing amounts of labor on a fixed amount of land, showing total product first rising at an increasing rate, then a diminishing rate, and eventually falling as marginal returns become negative.
This document discusses cardinal and ordinal utility analysis. It provides details on:
- Cardinal utility which holds that utility can be measured in units, while ordinal utility holds that utility can only be compared between options.
- The law of diminishing marginal utility which states that as consumption of a good increases, the marginal utility from each additional unit decreases.
- Total utility, marginal utility, and the relationship between the two. Total utility increases at a diminishing rate while marginal utility decreases.
- The law of equi-marginal utility which explains how a consumer allocates a limited budget across goods to maximize utility by equating marginal utility across goods. Indifference curves and indifference schedules are used to illustrate this
The document discusses the concept of quasi rent. It defines quasi rent as a temporary gain earned by a factor of production due to a temporary limitation in its supply in the short run. Specifically:
- Quasi rent arises for capital equipment/machinery in the short run when its supply is fixed and it earns surplus over its transfer earnings.
- It is measured as the total revenue earned minus the total variable costs.
- Unlike economic rent which persists in both the short and long run, quasi rent disappears in the long run when the supply of the factor can be increased.
The document discusses different theories of cost, including traditional and modern theories. Under traditional theory, costs are categorized as total, average, and marginal in both the short-run and long-run. Total cost equals total fixed cost plus total variable cost. Average cost depends on average fixed and average variable cost. Marginal cost is the change in total cost from producing one additional unit. In the long-run, all costs are variable. Modern theory proposes cost curves are L-shaped rather than U-shaped as traditionally thought.
This unit discusses the theory of production. It defines production as converting resources into outputs that satisfy human wants. The key factors of production are land, labor, capital, and entrepreneurship. The production function shows the relationship between inputs like capital and labor, and the quantity of output produced. There are laws of variable proportions and returns to scale. Production optimization involves finding the least-cost combination of inputs using isoquants and isocost lines, where the tangency point indicates the producer's equilibrium.
The document discusses the law of variable proportions, which examines how output changes when the quantity of one input (the variable factor) is increased while keeping other inputs fixed. It defines the law, lists its assumptions, and explains it using a tabular example of increasing a fixed amount of land with varying labor. Total product, marginal product, and average product are calculated at each stage. Graphically, there are three stages: increasing returns, diminishing returns, and negative returns. Causes of each stage are also provided, such as underutilization of fixed factors in the first stage and imperfect substitutability of factors in later stages.
1. Returns to scale refers to the change in total output resulting from a proportional change in all inputs.
2. There are three types of returns to scale: increasing, constant, and diminishing.
3. Increasing returns to scale occur when a 1% increase in all inputs leads to a more than 1% increase in output. Constant returns mean a proportional change in output, while diminishing returns mean output increases by less than the input increase.

It also discusses production possibility frontiers and the basic assumptions of economics. Managerial economics is introduced as the application of economic principles to managerial decision making within an organization.

The marginal productivity theory of distribution Prabha Panth
The document discusses the neoclassical theory of distribution and the concept of factor payments. It addresses the "adding up" problem of whether total factor payments will equal total product. Wicksteed showed that under constant returns to scale and factors paid their marginal products, total revenue will equal total costs through Euler's theorem. However, this assumes a linear homogeneous production function. Later economists like Samuelson and Hicks found the condition is only met at the minimum point of the long-run average cost curve, where a firm has constant returns to scale.
The law of equi-marginal utility states that a consumer will maximize total utility when the marginal utility per unit of expenditure is equal across all goods purchased. It assumes consumers have limited incomes and try to allocate spending in a way that equalizes the marginal utility of each item. An example is provided showing that total utility is maximized when $4 is spent on apples and $2 on bananas, since the marginal utility of each good is equal at that allocation. There are several limitations and assumptions of the law, and it is important in areas like production, consumption, exchange and public finance.
1. An isoquant map shows technically efficient combinations of inputs that can produce different levels of output. Isoquant curves never intersect and higher curves represent higher output levels.
2. Isoquant curves slope downward and are convex to the origin due to falling marginal rate of technical substitution. They represent combinations of two factors of production.
3. Isoquant curves differ from indifference curves, which represent satisfaction from combinations of two goods, in that isoquants measure output levels while indifference curves do not, and isoquants are influenced by technical substitution possibilities between inputs while indifference curves are influenced by marginal rates of substitution between goods.
This document discusses the concept of utility in economics. It defines utility as the capacity of a good or service to satisfy human wants. The document outlines several key characteristics of utility, including that it is psychological, individual, relative, and cannot be objectively measured. It also discusses different types of utility related to production and consumption, including form utility, place utility, time utility, service utility, marginal utility, total utility, and average utility. The relationship between marginal utility and total utility is explored, noting that total utility is maximized when marginal utility reaches zero.
The Law of Variable Proportions states that as the quantity of one variable input is increased while holding other inputs fixed, total product will initially rise at an increasing rate, then at a decreasing rate, and eventually at a negative rate. It operates in the short-run when some factors can vary and others are fixed. The law is demonstrated through a schedule that shows as labor is incrementally increased from 1 to 6 units, total product first increases, then increases at a lower rate, and eventually decreases, moving from phases of increasing, diminishing, and negative returns.
Isoquant is also called as equal product curve or production indifference curve or constant product curve. Isoquant indicates various combinations of two factors of production which give the same level of output per unit of time.
Just as an indifference curve represents various combinations of two goods which give a consumer equal amount of satisfaction, an iso-product curve shows all possible combinations of two inputs physically capable of producing a given level of output. Since an iso-product curve represents those combinations which will result in the production of an equal quantity of output, the producer would be indifferent between them.
This law was given by Alfred Marshall in his book principle of economics.
It show particular pattern of change in output when some factor remain fixed.
Production depend upon factors of production , if factors of production are good, production may increase and vice-versa.
Production function show functional relationship between production and factors of production.
It refers to manner of change in output cost by the increase in all the input simultaneously and in the same proportion.
Returns refers to “change in physical output”
Scale refers to “quantity of input employed”
Change in scale means that all factors of production are increased or decreased in same proportion.
The cost advantage that arises with increased output of a product.
It arises because of the inverse relationship between the quantity produced and per-unit fixed cost.
Profit refers to the excess of receipts from the sale of goods over the expenditure incurred on producing them.
The amount received from the sale of goods is known as ‘revenue’ and the expenditure on production of such goods is termed as ‘cost’. The difference between revenue and cost is known as ‘profit’.
For example, if a firm sells goods for Rs. 10 crores after incurring an expenditure of Rs. 7 crores, then profit will be Rs. 3 crores.
This document discusses various investment concepts including:
1. Types of investments such as induced, autonomous, physical, financial and business assets.
2. Key determinants of investment including income, interest rates, Tobin's Q, and marginal efficiency of capital.
3. Multiplier effects including money, fiscal, and investment multipliers which measure the response of endogenous variables to exogenous changes.
4. The accelerator effect whereby growth in GDP encourages businesses to invest more in fixed assets like factories and machinery, further stimulating economic growth.
The document discusses the Cobb-Douglas production function. It defines the production function and its key inputs of capital, labor, land, and entrepreneurship. It then describes the Cobb-Douglas production function, which studies the relationship between two inputs - labor and capital - and total output. The basic formula for the Cobb-Douglas production function is presented. Properties of the Cobb-Douglas production function like constant returns to scale are explained using a graph. Criticisms of the Cobb-Douglas production function for only considering two inputs and assuming constant returns to scale are also summarized.
Law of variable proportion and law of return to scaleMohammed Jasir PV
This document discusses production and the laws of variable proportions and returns to scale. It contains the following key points:
1. The law of variable proportions explains short-run production and states that as one variable input is increased while others stay constant, total output initially increases at an increasing rate, then at a diminishing rate, and may eventually decrease.
2. There are three stages: increasing, diminishing, and negative returns to the variable input.
3. The law of returns to scale explains long-run production when all inputs change proportionally. There can be increasing, constant, or decreasing returns to scale depending on if output increases more than, equal to, or less than proportional to the input increase
Partial equilibrium, reference pricing and price distortion Devegowda S R
Partial equilibrium analysis examines how supply and demand interact in isolated markets. It assumes other markets are unchanged. A partial equilibrium exists when supply and demand are equal for a good, holding fixed other prices and incomes. This simplifies analysis but may not reflect real-world interactions between markets. Reference pricing refers to how consumers value a good relative to competitors' prices or a product's previous advertised price. Setting artificially high reference prices can mislead consumers into thinking they are getting a better deal. Price distortions occur when prices deviate from levels that would clear the market if all participants aimed to optimize returns. They can arise from inefficient transactions not aimed at return maximization.
Marginal efficiency of capital (MEC) refers to the expected rate of profitability of new investment. MEC is calculated based on the amount of expected profit and the cost of the capital asset. It indicates the internal rate of return of an extra unit of capital. Investment decisions are influenced by comparing the MEC to interest rates - investments will be made when MEC is higher than interest rates. Companies use MEC to evaluate investments by comparing the discounted present value of expected income to the price of the capital asset. The document then discusses factors that affect MEC and provides a case study of how Nike used MEC to evaluate an investment decision.
Williamson’s model of managerial discretionPrabha Panth
1) Williamson's model of managerial discretion posits that in imperfect markets, managers will seek to maximize their own utility rather than profits for owners.
2) The model suggests that manager's utility depends on three variables: staff expenditures which boost sales and prestige; management emoluments such as perks; and discretionary investments for ego and pride.
3) Managers have an area of discretion between the actual profits earned and the minimum profits expected by owners, within which they can allocate resources to maximize their own satisfaction defined by the three variables.
A producer's equilibrium refers to the level of output where the producer earns maximum profits. This occurs where marginal revenue equals marginal cost and marginal cost is rising. There are two approaches to determining producer's equilibrium - the total revenue and total cost approach, and the marginal revenue and marginal cost approach. Under both approaches, equilibrium is reached at the quantity of output where marginal revenue equals marginal cost and marginal cost is rising. This equilibrium can be illustrated using diagrams with output on the x-axis and costs/revenues on the y-axis.
National income is the total value of all goods and services produced in a country in a year. It can be measured using various methods such as the production, income, and expenditure methods. The production method sums the value of output from all sectors. The income method sums factor incomes like wages, interest, rent, and profits. The expenditure method sums expenditures on consumption, investment, government spending, and exports/imports. National income statistics are important for measuring economic growth, standards of living, and making country comparisons.
The document discusses the economic implications of elasticity of substitution. It is introduced as a measure of how easily one input can be substituted for another when their prices change. Elasticity of substitution has various applications, including interpreting the substitutability of inputs, production theory involving profit maximization and cost minimization, and specifying common production functions like Cobb-Douglas, constant elasticity of substitution, and translog that determine the elasticity between input pairs. The document provides mathematical expressions and diagrams to explain these concepts.
This document provides an overview of the simple Keynesian model of income determination. It discusses the key components of aggregate expenditure, including consumption which depends on disposable income, and investment which depends on the marginal efficiency of capital and interest rates. The aggregate output is determined by the factors of production using a production function. Equilibrium income is reached at the point where aggregate expenditure and aggregate output intersect, establishing equilibrium in the goods market.

This document discusses the theory of production. It defines production as transforming inputs like labor, machines, and raw materials into an output. It notes production can take various forms beyond just manufacturing, such as transportation or intangible services. Inputs are classified as fixed or variable, with fixed inputs having an inelastic supply in the short run. A production function describes the relationship between inputs and outputs. The law of variable proportions states that as the proportion of factors changes, total production first increases at an increasing rate, then at a decreasing rate, with three stages of production. Rational decision making for firms operates in the stage where returns are increasing but fixed inputs are not yet being used uneconomically.

Eliott Dear Lawyer is telling the Laws of return as the law of cost. Eliott Dear is a regarded attorney in New York. He has over ten years of involvement with his lawful work.
The production function explains the relationship between inputs and output in economics. There are four main factors of production: land, labor, capital, and entrepreneurship. These can be fixed or variable factors. The production function formula is Q=f(K,L) where Q is output and K and L represent capital and labor. There are short-run and long-run production functions depending on whether inputs are fixed or variable. The law of variable proportions describes how marginal product decreases as the variable input increases in three stages: increasing, diminishing, and negative returns. Returns to scale refers to the proportional change in output from a proportional change in all inputs and can be increasing, constant, or diminishing.
The document discusses the law of variable proportions, which states that as the quantity of one input is increased while holding other inputs fixed, a production process will experience three stages: initially increasing returns followed by diminishing returns and eventually negative returns. It provides an example using land, labor and wheat production, and includes a table showing total, marginal and average product at different labor levels and a graph illustrating the three stages of the law.
1. Alfred Marshall distinguished between internal and external economies of scale. Internal economies occur within a firm as it increases production and reduces costs. External economies occur outside a firm, within an industry, such as when a transportation network improves and reduces costs for all firms.
2. The production function specifies the maximum output possible from different combinations of inputs, based on current technology. It represents the technological relationship but not economic choices.
3. In the long run, firms can enter or exit industries, increase or decrease plant size, and adopt new technologies. In the short run, firms can increase, decrease, or shut down production using variable inputs, with fixed inputs constrained.
The document discusses the law of returns, which governs production. There are two types of laws of returns: 1) The law of variable proportions, also known as the law of diminishing returns, states that as increments of a variable input are added to fixed inputs, marginal product will eventually diminish. 2) The law of returns to scale analyzes production in the long run. The law of variable proportions includes three stages: increasing returns initially as organization improves, then diminishing returns as marginal product declines, and finally negative returns. The law is illustrated with a graph analysis of stages of production.
The document summarizes the law of variable proportions, also known as the law of diminishing returns. It states that as a variable input (like labor) is increased while fixed inputs (like land and capital) are held constant, marginal and average product will initially increase, then diminish and eventually become negative. There are three stages: 1) increasing returns, 2) diminishing returns, and 3) negative returns. Causes of each stage are explained. A table and graph are provided to illustrate the three stages of the law of variable proportions.
This document discusses production theory and cost theory in the short run. It defines key concepts such as production, inputs, outputs, production functions, fixed and variable inputs, total product, average product and marginal product. It explains the three stages of production based on these productivity measures. It also introduces isoquants and isocost lines to determine optimal input combinations. Finally, it defines total, fixed, variable and average costs, and how total cost is calculated in the short run.
CH 4 The Theory of Production and Cost.pptxDawitHaile12
This chapter discusses production theory and cost theory in the short run. It defines key concepts such as production function, fixed and variable inputs, total product, average product and marginal product. It explains the three stages of production in the short run based on the law of diminishing returns. It also defines total, average and marginal costs, and describes how they change with output based on the total, average and marginal cost curves. Finally, it discusses the relationship between short run production functions and cost functions.
The document discusses production functions and their key components. It defines a production function as explaining the quantitative relationship between inputs and outputs in production. There are four main components: inputs, outputs, short-run production functions where one input is variable, and long-run production functions where all inputs are variable. The document also discusses concepts like total product, marginal product, average product, the law of diminishing returns, and returns to scale.
This document discusses the short run production function and the law of variable proportions. It defines the short run as a period where at least one input is fixed. The production function shows the relationship between inputs like labor, capital, land, and outputs. In the short run, outputs increase at an increasing rate initially as variable inputs like labor are added, reaching a point of maximum output, after which outputs increase at a diminishing rate and can become negative. This follows the law of variable proportions, where marginal product initially increases with more variable input, then decreases and can become negative. The document provides an example of increasing wheat output with more labor on a fixed amount of land, and a graph illustrating the three stages of the law of
The document discusses Philips' brand repositioning strategy around "sense and simplicity". It outlines that Philips' products had become too complex, so the company refocused on simplicity through customer research. Key aspects of the new strategy include advanced yet easy-to-use technologies, a consistent message communicated globally, and products like Senseo coffee makers that embody the brand promise.
The document discusses production and the factors that influence it. It defines production as the process of transforming raw materials into final products using labor and capital. Production depends on four main factors: land, labor, capital, and entrepreneurship. It then describes three laws of production - the law of variable proportions, and the laws of increasing, constant, and diminishing returns to scale. It provides an example case study to illustrate the law of variable proportions in relation to labor productivity.
The document discusses the theory of production, including defining key concepts like the production function and factors of production. It explains that a production function shows the relationship between inputs like labor and capital to the output of a firm. The document also covers the laws of variable proportions and diminishing returns, noting that initially adding more of one input leads to increasing returns but eventually marginal returns decrease. Finally, it provides an example of how marginal product changes as labor is added to fixed land and capital, going through stages of increasing, diminishing, and eventually negative returns.
The document discusses the laws of production, including the law of diminishing returns (law of variable proportions) and laws of returns to scale. It explains that under the law of diminishing returns, as one input is increased while others stay constant, total output increases at an increasing rate initially, then at a diminishing rate, until it eventually decreases. It also discusses the three stages of production - increasing, diminishing, and negative returns - under this law. The laws of returns to scale analyze production over the long run when all inputs change proportionally. There can be increasing, constant, or diminishing returns to scale.
1) This document discusses various concepts related to production analysis including factors of production, production functions, laws of variable proportions, isoquants, marginal rate of technical substitution, and returns to scale.
2) The factors of production are land, labor, capital, and entrepreneurship. Production functions include fixed proportion, variable proportion, linear homogeneous, Cobb-Douglas, and constant elasticity of substitution.
3) The law of variable proportions explains how output increases at different rates as one variable input is increased while others stay fixed. Returns to scale refers to how output changes as all inputs change proportionately.
The law of variable proportions states that when one variable input is increased while other inputs are held fixed, marginal productivity initially increases but eventually decreases. It assumes technology remains constant and one input can vary while others are fixed. Marginal productivity rises until the third worker is added, then falls, reaching zero at the sixth worker and becoming negative at the seventh worker. The law has three stages: increasing returns as marginal exceeds average productivity, diminishing returns as both fall but remain positive, and negative returns as marginal productivity declines below zero.
Production function.pptxjfjfnvndnfjffnfnfjfjfSahitiDarika
The production function relates factor inputs to output and represents the technology available to transform inputs into outputs. It includes all technically efficient methods of production. The production function is relevant for both the short run, where only variable inputs can be adjusted, and the long run, where all inputs can be varied. Key concepts include total physical product (TPP), average physical product (APP), and marginal physical product (MPP). TPP measures total output, APP measures output per input, and MPP measures the change in output from an extra unit of input. Their relationship can be depicted graphically, with TPP typically increasing at an increasing, then diminishing, rate as MPP first rises then falls.
The document discusses the demand for labor from the perspective of individual firms and the overall labor market. It explains that in the short-run, a firm's demand for labor (its marginal revenue product curve) depends on the marginal product of labor. In the long-run, when both capital and labor are variable, firms will substitute between the two inputs in response to wage changes. The market demand for labor is less elastic than the sum of individual firm demands, due to product price effects. The elasticity of labor demand depends on factors like the elasticity of product demand and the share of labor costs in total costs.

Association rule mining is used to find relationships between items in transaction data. It identifies rules that can predict the occurrence of an item based on other items purchased together frequently. Some key metrics used to evaluate rules include support, which measures how frequently an itemset occurs; confidence, which measures how often items in the predicted set occur given items in the predictor set; and lift, which compares the confidence to expected confidence if items were independent. An example association rule evaluated is {Milk, Diaper} -> {Beer} with support of 0.4, confidence of 0.67, and lift of 1.11.
This document discusses clustering, which is the task of grouping data points into clusters so that points within the same cluster are more similar to each other than points in other clusters. It describes different types of clustering methods, including density-based, hierarchical, partitioning, and grid-based methods. It provides examples of specific clustering algorithms like K-means, DBSCAN, and discusses applications of clustering in fields like marketing, biology, libraries, insurance, city planning, and earthquake studies.
Classification is a data analysis technique used to predict class membership for new observations based on a training set of previously labeled examples. It involves building a classification model during a training phase using an algorithm, then testing the model on new data to estimate accuracy. Some common classification algorithms include decision trees, Bayesian networks, neural networks, and support vector machines. Classification has applications in domains like medicine, retail, and entertainment.
The document discusses the assumptions and properties of ordinary least squares (OLS) estimators in linear regression analysis. It notes that OLS estimators are best linear unbiased estimators (BLUE) if the assumptions of the linear regression model are met. Specifically, it assumes errors have zero mean and constant variance, are uncorrelated, and are normally distributed. Violation of the assumption of constant variance is known as heteroscedasticity. The document outlines how heteroscedasticity impacts the properties of OLS estimators and their use in applications like econometrics.
This document provides an introduction to regression analysis. It discusses that regression analysis investigates the relationship between dependent and independent variables to model and analyze data. The document outlines different types of regressions including linear, polynomial, stepwise, ridge, lasso, and elastic net regressions. It explains that regression analysis is used for predictive modeling, forecasting, and determining the impact of variables. The benefits of regression analysis are that it indicates significant relationships and the strength of impact between variables.
MYCIN was an early expert system developed at Stanford University in 1972 to assist physicians in diagnosing and selecting treatment for bacterial and blood infections. It used over 600 production rules encoding the clinical decision criteria of infectious disease experts to diagnose patients based on reported symptoms and test results. While it could not replace human diagnosis due to computing limitations at the time, MYCIN demonstrated that expert knowledge could be represented computationally and established a foundation for more advanced machine learning and knowledge base systems.
The document discusses expert systems, which are computer applications that solve complex problems at a human expert level. It describes the characteristics and capabilities of expert systems, why they are useful, and their key components - knowledge base, inference engine, and user interface. The document also outlines common applications of expert systems and the general development process.
The Dempster-Shafer Theory was developed by Arthur Dempster in 1967 and Glenn Shafer in 1976 as an alternative to Bayesian probability. It allows one to combine evidence from different sources and obtain a degree of belief (or probability) for some event. The theory uses belief functions and plausibility functions to represent degrees of belief for various hypotheses given certain evidence. It was developed to describe ignorance and consider all possible outcomes, unlike Bayesian probability which only considers single evidence. An example is given of using the theory to determine the murderer in a room with 4 people where the lights went out.
A Bayesian network is a probabilistic graphical model that represents conditional dependencies among random variables using a directed acyclic graph. It consists of nodes representing variables and directed edges representing causal relationships. Each node contains a conditional probability table that quantifies the effect of its parent nodes on that variable. Bayesian networks can be used to calculate the probability of events occurring based on the network structure and conditional probability tables, such as computing the probability of an alarm sounding given that no burglary or earthquake occurred but two neighbors called.
This document discusses knowledge-based agents in artificial intelligence. It defines knowledge-based agents as agents that maintain an internal state of knowledge, reason over that knowledge, update their knowledge based on observations, and take actions. Knowledge-based agents have two main components: a knowledge base that stores facts about the world, and an inference system that applies logical rules to deduce new information from the knowledge base. The document also describes the architecture of knowledge-based agents and different approaches to designing them.
A rule-based system uses predefined rules to make logical deductions and choices to perform automated actions. It consists of a database of rules representing knowledge, a database of facts as inputs, and an inference engine that controls the process of deriving conclusions by applying rules to facts. A rule-based system mimics human decision making by applying rules in an "if-then" format to incoming data to perform actions, but unlike AI it does not learn or adapt on its own.
This document discusses formal logic and its applications in AI and machine learning. It begins by explaining why logic is useful in complex domains or with little data. It then describes logic-based approaches to AI that use symbolic reasoning as an alternative to machine learning. The document proceeds to explain propositional logic and first-order logic, noting how first-order logic improves on propositional logic by allowing variables. It also mentions other logics and their applications in areas like automated discovery, inductive programming, and verification of computer systems and machine learning models.
The document discusses production systems, which are rule-based systems used in artificial intelligence to model intelligent behavior. A production system consists of a global database, set of production rules, and control system. The rules fire to modify the database based on conditions. Different control strategies are used to determine which rules fire. Production systems are modular and allow knowledge representation as condition-action rules. Examples of applications in problem solving are provided.
The document discusses game playing in artificial intelligence. It describes how general game playing (GGP) involves designing AI that can play multiple games by learning the rules, rather than being programmed for a specific game. The document outlines how the minimax algorithm is commonly used for game playing, involving move generation and static evaluation functions to search game trees and determine the best move by maximizing or minimizing values at each level.

Although the lungs are one of the most vital organs in the body, they are vulnerable to infection and injury. COVID-19 has put the entire world in an unprecedented difficult situation, bringing life to a halt and claiming thousands of lives all across the world. Medical imaging, such as X-rays and computed tomography (CT), is essential in the global fight against COVID-19, and newly emerging artificial intelligence (AI) technologies are boosting the power of imaging tools and assisting medical specialists. AI can improve job efficiency by precisely identifying infections in X-ray and CT images and allowing further measurement. We focus on the integration of AI with X-ray and CT, both of which are routinely used in frontline hospitals, to reflect the most recent progress in medical imaging and radiology combating COVID-19.

2. • Law of Variable Proportion is regarded as an important theory in
Economics. It is referred to as the law which states that when the
quantity of one factor of production is increased, while keeping all
other factors constant, it will result in the decline of the marginal
product of that factor.
• Law of variable proportion is also known as the Law of
Proportionality. When the variable factor becomes more, it can lead
to negative value of the marginal product.
The law of variable proportion can be understood in the following way:
• When variable factor is increased while keeping all other factors
constant, the total product will increase initially at an increasing rate,
next it will be increasing at a diminishing rate and eventually there
will be decline in the rate of production.
3. Assumptions of Law of Variable Proportion
Law of variable proportion holds good under certain circumstances,
which will be discussed in the following lines.
• Constant state of Technology: It is assumed that the state of
technology will be constant and with improvements in the
technology, the production will improve.
• Variable Factor Proportions: This assumes that factors of production
are variable. The law is not valid, if factors of production are fixed.
• Homogeneous factor units: This assumes that all the units produced
are identical in quality, quantity and price. In other words, the units
are homogeneous in nature.
• Short Run: This assumes that this law is applicable for those systems
that are operating for a short term, where it is not possible to alter all
factor inputs.
4. Stages of Law of Variable Proportion
The Law of Variable proportions has three stages, which are discussed
below.
• First Stage or Stage of Increasing returns: In this stage, the total
product increases at an increasing rate. This happens because the
efficiency of the fixed factors increases with addition of variable
inputs to the product.
• Second Stage or Stage of Diminishing Returns: In this stage, the total
product increases at a diminishing rate until it reaches the maximum
point. The marginal and average product are positive but diminishing
gradually.
• Third Stage or Stage of Negative Returns: In this stage, the total
product declines and the marginal product becomes negative.
5. • Producer’s equilibrium will be determined at OQ level of output g
corresponding to point E because at this, the following two conditions
are met:
OQ Units Sold
(a) MC = M, and
(b) MC curve cuts the MR curve from below.
• When MR > MC, then producer will continue to produce as long as MR
becomes equal to MC. It is so because firm will find it profitable to raise the
output level.
• When MR < MC, then producer will cut down the production as long as MR
becomes equal to MC. It is so because firm will find it Unprofitable to produce
an extra unit. So, it starts reducing the level of output till MR = MC.
So, the producer is at equilibrium at OQ units of output.
6. For our example, we are assuming that labour is a variable factor. Hence, we
have following table-
We are increasing the total number of labours working on a machine. Remember that we can't
afford to buy a new machine as we are in the short run, but we can surely increase the number
of labours working on the machine. Hence, we gradually increase the labour from one to eleven.
7. From the table above, we can observe the following:
• The Total Product increases with increase in labour but later it falls.
• The Average product too increases initially and later starts falling.
• The Marginal Product also increases initially but later falls.
8. • Now if we concentrate only on the Marginal product, we will understand that the 1st labor has produced
100 units but the 2nd has produced 110 units and the third has produced even more i.e.130 units. But the
question arises why? why it so happens that the second and third labours are producing more than the first?
• It happens because of ‘division of labour’. As the number of labours are increasing on a machine, the
efficiency of the new labour will increase initially because of division of work.
• In sports like cricket too something similar happens more often. The batsman at number 3 generally scores
more than the batsman at number 1 position. This happens because when the batsmen at number one and
two position open the innings, they set a good platform for the batsman at number 3 position to score more.
• If we observe the behavior of the marginal product further, we would know that it is gradually falling. Hence,
the new worker is producing lesser units than the earlier one. But why does this happen? What makes the
new worker produce less? Won’t the division of work apply here?
• The answer to this is that, as the number of workers are increasing, there is very little work left for the new
worker to do on the machine. Hence, the end workers have very little to contribute as already maximum
work is done by the initial workers.
• Comparing thus with cricket again, the tailenders will contribute to the score of a team but their
contribution will be negligible. This is because, they don’t have much overs to play in a limited overs game.
• Also, the marginal product of the 11th labour is negative. This would clearly imply that the 11th labour is not
needed. The machine in the example can only have a maximum of 10 labours. Hence, if there is excess
labour, this would create a havoc and the disturbance would cause the ‘Total Product’ to fall instead of
rising.
• Hence, a prudent entrepreneur stops at the end of stage 2 as shown in the table where the ‘Total Product’ is
maximum and the ‘Marginal Product’ is zero.
9. Understanding the stages:
• This is how the graph looks like-
1.Stage 1- Law of increasing returns: Here, the total
product increases at a faster rate. The marginal product
increases and then falls. The average product increases
and reaches its maximum point.
2.Stage 2- Law of diminishing returns: Here, the total
product increases at a slower rate and reaches its
maximum point. The average product falls for the very first
time.
3.Stage 3- Law of negative returns: Here, the total
product falls for the very first time. The average product
falls further and the marginal product goes negative for
the very first time.
