Market Equilibrium & Price

Learning Objective: Determine market equilibrium and explain price controls

In Nepal's vegetable markets, you might notice that the price of tomatoes settles at a certain level where farmers are willing to sell and buyers are willing to buy. This natural settling point is the market equilibrium. But what happens when the government steps in and sets prices? Understanding equilibrium and price controls is essential for grasping how markets function.

Market Equilibrium

Equilibrium occurs where the demand curve and supply curve intersect -- the price at which the quantity demanded equals the quantity supplied.

Example: In Kalimati vegetable market, Kathmandu:

• At Rs. 80/kg of tomatoes, suppliers want to sell 500 kg and buyers want to buy 500 kg.
• This is the equilibrium price (Rs. 80) and equilibrium quantity (500 kg).

What Happens Away from Equilibrium?

Surplus (Excess Supply): When the price is above equilibrium, quantity supplied exceeds quantity demanded. Sellers are left with unsold goods and must lower prices.

• Example: If tomatoes are priced at Rs. 120/kg, sellers bring 800 kg but buyers only want 300 kg. The 500 kg surplus forces the price down.

Shortage (Excess Demand): When the price is below equilibrium, quantity demanded exceeds quantity supplied. Buyers compete, pushing the price up.

• Example: If tomatoes are priced at Rs. 40/kg, buyers want 900 kg but sellers only bring 200 kg. The shortage drives prices upward.

Government Price Controls

Sometimes the government intervenes in markets to protect consumers or producers.

Price Ceiling (Maximum Price)

A legal maximum price set below the equilibrium. The goal is to make essential goods affordable.

Example: Nepal's government occasionally sets maximum retail prices for essential commodities during emergencies. If the equilibrium price of cooking oil is Rs. 250/liter but the ceiling is set at Rs. 200, there will be a shortage because demand exceeds supply at that lower price.

Price Floor (Minimum Price)

A legal minimum price set above the equilibrium. The goal is to protect producers.

Example: Minimum support price for agricultural products. If the government sets a minimum price of Rs. 30/kg for paddy to protect farmers, but the market price would naturally be Rs. 22/kg, there will be a surplus of paddy.

| Control | Set At | Result | Purpose | |---------|--------|--------|---------| | Price Ceiling | Below equilibrium | Shortage | Protect consumers | | Price Floor | Above equilibrium | Surplus | Protect producers |

Other Forms of Government Intervention

• Subsidies: The Nepal government subsidizes fertilizers to reduce farming costs.
• Taxes: Excise taxes on cigarettes and alcohol raise prices to discourage consumption.
• Buffer stock schemes: Government buys excess production during good harvests and releases it during shortages.

Key Term: Equilibrium is the point where quantity demanded equals quantity supplied, and there is no tendency for the price to change.

Summary

• Market equilibrium is where demand equals supply at a particular price.
• Prices above equilibrium create surpluses; prices below create shortages.
• Price ceilings protect consumers but can cause shortages.
• Price floors protect producers but can cause surpluses.
• The Nepal government uses subsidies, taxes, and price controls to manage markets.
