Class 12 Microeconomics Sandeep Garg Solutions Chapter 11 – Price Determination with Simple Applications
FAQs on Microeconomics Class 12: Sandeep Garg Chapter 11 Solutions
1. What key topics are covered in the solutions for Sandeep Garg's Class 12 Microeconomics Chapter 11 on Price Determination?
The solutions for Chapter 11 primarily cover the determination of market equilibrium under perfect competition. Key topics include:
- The concept of market equilibrium and how equilibrium price and quantity are determined.
- Situations of disequilibrium, such as excess demand and excess supply, and the chain of effects that restore equilibrium.
- The impact of shifts in demand and supply curves on the equilibrium price and quantity.
- Simple applications of demand and supply tools, including the concepts and implications of price ceilings and price floors.
For a comprehensive overview, you can refer to the Market Equilibrium Class 12 Notes.
2. What is market equilibrium as explained in Class 12 Microeconomics?
Market equilibrium is a state in a market where the quantity demanded for a commodity is exactly equal to the quantity supplied of it. This occurs at the intersection of the demand curve and the supply curve. At this point, there is no tendency for the market price or quantity to change, as all buyers who want to buy at that price find sellers, and all sellers who want to sell at that price find buyers. This specific price is known as the equilibrium price, and the quantity is called the equilibrium quantity.
3. How do market forces restore equilibrium when there is excess demand?
Excess demand, or a shortage, occurs when the quantity demanded is greater than the quantity supplied at the prevailing market price. This situation triggers a chain of effects:
- Competition among buyers: Since there are more buyers than goods available, buyers compete with each other, leading them to offer higher prices.
- Price increases: This competition pushes the market price upwards.
- Market response: As the price rises, two things happen based on the laws of demand and supply. Demand contracts (decreases) and supply extends (increases).
- Restoration of equilibrium: This process continues until the price reaches a new, higher level where quantity demanded once again equals quantity supplied, thus restoring equilibrium.
4. What is meant by 'excess supply' and how does it affect the market price?
Excess supply, or a surplus, is a market condition where the quantity supplied of a commodity is greater than the quantity demanded at the prevailing price. This surplus puts downward pressure on the price due to the following mechanism:
- Competition among sellers: Sellers are unable to sell all their goods at the current price, leading to competition among them to attract buyers.
- Price decreases: To clear their unsold stock, sellers start lowering the price.
- Market response: As the price falls, demand extends (increases) and supply contracts (decreases).
- Restoration of equilibrium: The price continues to fall until it reaches a new, lower equilibrium level where the surplus is eliminated and the market clears.
5. What happens to the equilibrium price and quantity when there is a simultaneous increase in both demand and supply?
When both demand and supply increase simultaneously, the equilibrium quantity will definitely increase. However, the effect on the equilibrium price is uncertain and depends on the relative magnitude of the increases in demand and supply.
- If the increase in demand is greater than the increase in supply, the equilibrium price will rise.
- If the increase in demand is less than the increase in supply, the equilibrium price will fall.
- If the increase in demand is equal to the increase in supply, the equilibrium price will remain unchanged.
6. What is a 'price ceiling' and what are its main consequences in a market?
A price ceiling is a maximum price for a good or service that is fixed by the government, and it is set below the natural equilibrium price. It is typically implemented to make essential commodities affordable for poorer sections of society. The main consequences are:
- Persistent Shortage: Since the price is kept artificially low, quantity demanded exceeds quantity supplied, leading to a chronic shortage.
- Black Marketing: A black market may emerge where the good is sold illegally at a price higher than the government-mandated ceiling.
- Rationing: The government might have to resort to a rationing system to ensure fair distribution of the limited supply among consumers.
This topic is a key application within the CBSE Class 12 Economics Syllabus 2024-25.
7. What is a 'price floor' and why is it implemented?
A price floor is a minimum price fixed by the government for a particular good or service, set above the market equilibrium price. It is primarily implemented to protect the interests of producers by ensuring they receive a certain minimum income for their output. A common example is the Minimum Support Price (MSP) for agricultural crops. The main consequence of a price floor is a persistent surplus, as the artificially high price leads to quantity supplied exceeding quantity demanded.
8. How can using the solutions for Sandeep Garg's Chapter 11 help in preparing for the CBSE Class 12 Economics exam?
Using the Sandeep Garg solutions for Chapter 11 helps in exam preparation by breaking down complex concepts into understandable steps. They clarify the graphical analysis of shifts in demand and supply and provide practice with numerical and conceptual questions that are frequently asked in board exams. By working through these solutions, students can master the 'chain of effects' for disequilibrium scenarios and understand the real-world applications of price ceilings and floors, aligning their preparation with the latest NCERT Solutions for Class 12 Micro Economics guidelines.
