Demand is the quantity of a product that people are willing and able to buy at a particular price. The Law of Demand shows inverse relationship - as price rises, quantity demanded decreases, and vice versa.

Individual demand is the quantity a particular consumer wants to buy at different prices. Market demand is the sum of all individual demands at different prices.

Supply is the quantity that sellers are willing and able to offer at a particular price. The Law of Supply shows direct relationship - as price rises, quantity supplied increases.

Market equilibrium is where quantity demanded equals quantity supplied. At this point, there is neither shortage nor surplus, and prices tend to remain stable unless external factors change.

Substitute goods can replace each other. When price of one rises, demand for the other increases. Examples: Tea and coffee, laptops and computers, apples and bananas.

Complementary goods are used together. When demand for one rises, demand for the other also rises. Examples: Smartphones and earphones, cars and petrol, printers and cartridges.

Price ceiling sets maximum price for a product (like medicines). Price floor sets minimum price (like minimum wage). Both are government interventions in the market.

Public goods are provided by government for all citizens. They are not provided by private companies as they don't generate profit. Examples: Roads, streetlights, parks, national defence.

A monopoly is a market with a single seller controlling entire supply. It is regulated because it may charge higher prices, provide poorer quality, and restrict supply.

Factors include price, income, price of related goods (substitutes and complements), tastes and preferences, seasonality, future price expectations, and population.

Factors include price, price of related goods, number of sellers, technology, future expectations, cost of inputs, and weather or natural disasters.

Market demand aggregates many consumers, so the same price change creates a larger total quantity response. This makes the market curve flatter and more responsive. 5-MARK QUESTIONS (100 Words with Intro - Points - Conclusion)

Introduction: Demand is the quantity of a product that people are willing and able to buy at a particular price, depending on their needs, preferences, season, trend, and income.
Points:
• Law of Demand: Inverse relationship - as price falls, quantity demanded increases. Example: Mangoes at ₹150 (1 kg), at ₹100 (2 kg), at ₹50 (3 kg).
• Price of Related Goods: Substitute goods (tea and coffee) - if coffee price rises, tea demand increases. Complementary goods (smartphones and earphones) - if smartphone demand rises, earphone demand rises.
• Income: When income rises, consumers can buy more. Example: More income leads to higher demand for quality products.
• Taste and Preference: Individual choices matter. Example: A person liking mangoes won't substitute oranges even if cheaper.
• Other Factors: Seasonality (sweaters in winter), future expectations (buy before price rise), population (more children = more sports shoes demand).
Conclusion: Demand is influenced by multiple factors beyond just price.

Introduction: Supply is the quantity of a product that sellers are willing and able to offer at a particular price.
Points:
• Law of Supply: Direct relationship - as price rises, quantity supplied increases. Higher prices increase profitability, incentivising producers to increase output.
• Price of Related Goods: If wheat prices are low but chickpea prices are high, farmers grow more chickpeas. Example: A farmer faces two choices and chooses more profitable crop.
• Number of Sellers: More sellers increase market supply, causing prices to fall. Fewer sellers cause supply shortage and price rise.
• Technology: Improvement in technology reduces cost, allowing more production. Example: Drip irrigation increases yield; cold storage increases market supply.
• Future Expectations: If producers expect higher demand, they produce more. If expecting lower demand, they reduce production.
Conclusion: Supply responds to various factors including price, costs, technology, and expectations.

Introduction: Market equilibrium is the point where supply of goods equals demand, meaning there is no excess supply or excess demand.
Points:
• Schedule Example: At ₹40, demand (3 kg) > supply (8 kg) - excess demand. At ₹100, demand (12 kg) = supply (12 kg) - equilibrium. At ₹150, demand (8 kg) < supply (43 kg) - excess supply.
• Equilibrium Point: At price ₹100, quantity demanded equals quantity supplied. Market is 'cleared' - neither shortage nor surplus.
• Excess Demand: When price is below equilibrium, more people want to buy than available. Competition among buyers pushes price up.
• Excess Supply: When price is above equilibrium, more is available than people want to buy. Competition among sellers pushes price down.
• Graph: Demand curve (downward sloping) intersects supply curve (upward sloping) at equilibrium point E.
Conclusion: Prices adjust naturally to reach equilibrium through demand and supply interactions.

Introduction: India is a market-based, regulated economy where government intervenes when markets fail to produce fair outcomes.
Points:
• Regulation of Unfair Practices: Government sets price ceiling for essential goods (medicines) and price floor (minimum wage). During COVID-19, sanitisers price capped at ₹100.
• Regulators: RBI (banking), TRAI (telecommunications), SEBI (securities market), Central Consumer Protection Authority protect consumers from exploitation.
• Public Goods: Government provides roads, parks, streetlights, national defence as private companies won't provide them due to lack of profit.
• Monopoly Regulation: Single seller dominating market can charge higher prices. Government regulates such practices.
• Limitations: Excessive intervention can cause price distortions, reduce producer incentives, discourage innovation, and create compliance burdens.
Conclusion: Government intervention balances market efficiency with public welfare, but must be implemented carefully.

Introduction: In theory, equilibrium is an intersection point between demand and supply. In the real world, markets are dynamic with constantly changing conditions.
Points:
• Real World vs Theory: Markets are always adjusting to new equilibrium, never fully settling at the previous one. Changes in technology, wages, wars, pandemics, weather alter demand and supply.
• COVID-19 Example (2020): Demand for face masks surged rapidly. Supply couldn't catch up, prices rose significantly. Over time, suppliers adjusted and prices fell. After pandemic, prices reduced to pre-pandemic levels.
• Hotel Tariff Example: Hotels change prices based on demand, season, and special situations. Off-season (₹1,500), tourist season (₹8,000), New Year's Eve (₹25,000).
• Factors in Dynamic Markets: How fast rooms are booked, nearby hotel tariffs, festivals/conferences, weather forecasts, past booking trends.
• Conclusion: Markets are not machines with fixed equilibria but dynamic systems that constantly adapt, evolve, and respond to changing conditions.
Conclusion: Understanding market dynamics helps decode how prices change in real life.
