Production and Laws of Production

(Curated by lunotes.in)

Meaning of Production

In economics, production refers to the creation of goods and services (material or non-material) with the purpose of selling them in the market. It includes converting raw materials into finished goods.

Laws of Production

These laws deal with cost analysis and producer’s equilibrium, helping businesses determine the most profitable level of output.

There are two major laws:

1. Law of Variable Proportions (Short Run)

This law explains the relationship between input and output when only one input is variable and others remain fixed.

Definition (Marshall):

“An increase in the amount of labour and capital applied in cultivation leads to a less than proportionate increase in output, unless accompanied by improvements in technology.”

Key Concepts:

• Total Product (TP): Total output produced.

• Average Product (AP):
  
  $AP = frac{TP}{L}$AP=LTP​

• Marginal Product (MP):
  
  $MP = frac{∆TP}{∆L}$MP=∆L∆TP​ or
  
  $MP = TP_n – TP_{n-1}$MP=TPn​−TPn−1​

Three Stages of the Law:

MP intersects AP at AP’s maximum.

Law is also called Law of Diminishing Marginal Returns.

Reasons for Diminishing Returns:

• Variable factors not homogeneous

• Poor combination of inputs

• Limited substitution possibilities

Assumptions:

• Technology constant

• Short-run framework

• At least one fixed factor

• Units of variable factor are homogeneous

2. Law of Returns to Scale (Long Run)

This law examines output changes when all inputs are changed proportionately.

Types:

Example Table:

MP increases → constant → then decreases.

Difference: Variable Proportion vs Returns to Scale

Production Function

It shows the technical relationship between inputs and output for a given technology.

Formula:

$$Q_x = A cdot f(F_1, F_2, F_3, …, F_n)$$Qx​=A⋅f(F1​,F2​,F3​,…,Fn​)

Where:

• $Q_x$Qx​: Output

• $F_1, F_2, …, F_n$F1​,F2​,…,Fn​: Inputs (Labour, Land, Capital etc.)

• $A$A: Technology factor

Types of Demand

There are three types of demand:

1. Price Demand

• Price demand shows the relationship between the price of a commodity and the quantity demanded.

• Law: When the price increases, the demand decreases, and when the price decreases, the demand increases (inverse relationship).

• The price demand curve slopes downwards from left to right.

$$Dx = f(Px)$$Dx=f(Px)

---

2. Income Demand

• Income demand explains the relationship between the consumer’s income and the demand for goods.

• Generally:

  • When income increases, demand increases.

  • When income decreases, demand decreases.

• The income demand curve usually slopes upwards from left to right for normal goods.

$$Dx = f(Y)$$Dx=f(Y)

Types of Income Demand:

• Normal or Superior Goods: Best quality goods. Demand increases with income. The curve slopes upwards.

• Inferior Goods: Lower quality goods. Demand decreases when income increases. The curve slopes downwards.

---

3. Cross Demand

• Cross demand shows the relationship between the price of one good and the demand for another good.

• It explains how substitutes and complementary goods affect demand.

$$Dx = f(Py)$$Dx=f(Py)

Types of Cross Demand:

• Substitute Goods:

  • Goods that can replace each other (e.g., tea and coffee, pen and pencil).

  • If the price of coffee rises, demand for tea rises.

  • The curve slopes upwards from left to right (direct relationship).

• Complementary Goods:

• Goods used together (e.g., car and petrol, cement and bricks).

• If the price of petrol rises, demand for cars falls.

• The curve slopes downwards from left to right (inverse relationship).

---

Change in Demand vs Change in Quantity Demanded

Changes in demand are of two types:

1. Extension and Contraction of Demand

• Happens due to change in price, keeping other factors constant.

• Extension: When price falls, demand increases.

• Contraction: When price rises, demand decreases.

• Single demand curve is used to explain this.

---

2. Increase and Decrease of Demand

• Happens when factors other than price (like income, taste, population) change, while price remains constant.

• Increase in Demand:

  • A new demand curve is formed to the right of the original.

• Decrease in Demand:

  • A new demand curve is formed to the left of the original.

Law of Demand

The Law of Demand states that, other things remaining constant, there is an inverse relationship between the price of a commodity and its quantity demanded.

• If price rises, demand falls.

• If price falls, demand rises.

Demand Function

The demand function shows the relationship between the quantity demanded and its determinants:

$$Dn = f(Pn, Ps, Pc, Y, T)$$Dn=f(Pn,Ps,Pc,Y,T)

Where:

• Dn = Demand for commodity ‘n’

• f = Functional relationship

• Pn = Price of the commodity

• Ps = Price of substitute goods

• Pc = Price of complementary goods

• Y = Income of the consumer

• T = Taste and preferences of the consumer

Managerial Economics is a branch of economics that applies economic concepts and tools to help businesses make better decisions. It plays a very important role in strategic decision-making, which means planning for the future to help the business grow and succeed.

Let’s understand some of the key roles of managerial economics in simple words:

🔹 1. Strategic Planning

Managerial economics helps in setting long-term goals for the business. It uses techniques like incremental analysis, which helps managers decide whether making small changes (like producing more or less of a product) will benefit the company. This helps in smart planning for the future.

🔹 2. Pricing Decisions

Setting the right price for a product is a big decision. Managerial economics helps by studying things like:

• How much it costs to make the product

• How much customers are willing to pay

• What competitors are charging
  
  With this, managers can decide the best price that brings profit while staying competitive in the market.

🔹 3. Risk Analysis

Every business decision has some risk. Managerial economics helps to identify, measure, and reduce risks. It uses tools like risk analysis, which helps managers understand what could go wrong and how to prepare for it.

🔹 4. Market Analysis

It helps businesses understand the market better. For example, the equi-marginal principle teaches managers how to distribute resources in a way that gives maximum benefit. It also helps in knowing customer needs and competitor actions.

🔹 5. Demand Forecasting

Managerial economics helps predict future customer demand. If a company knows what people will want in the future, it can prepare in advance. This avoids losses and helps in better planning of production and supply.

🔹 6. Cost Control and Profit Planning

It helps businesses understand how to reduce unnecessary costs and make decisions that increase profits. For example, if a company finds a cheaper way to make the same product, it can save money and earn more.
