Students learning microeconomics or anyone interested in how government price controls affect markets.
TL;DR
This microeconomics lecture explains price controls (ceilings and floors) using ice cream market examples, discusses government intervention like Ukraine's green tariff and minimum wage, and shows how price caps can cause shortages or surpluses.
Key Takeaways
- Government price controls (ceiling or floor) disrupt market equilibrium, creating either a shortage (like with gasoline in 2022) or a surplus of goods.
- The example of Ukraine's green tariff shows that the government can set a floor price (above the market price) to stimulate production, not just to protect consumers.
- Minimum wage is a classic example of a floor price: if it is above the equilibrium level, it can cause unemployment due to an excess supply of labor.
- The Antimonopoly Committee monitors compliance with set prices, as in the case of the 'wholesale prices' pharmacy, which changed its name due to price discrepancies.
- Government intervention in fuel prices in 2022 led to shortages and queues, as the artificially low price reduced supply.
- Lobbying by producers or consumers can influence the adoption of price control laws, altering market conditions.
- A price ceiling protects consumers but can cause a shortage if set below the equilibrium price.

Questions & Answers
What are price controls and taxes in economics?
Price controls are government intervention in setting prices, for example, a ceiling (maximum) or floor (minimum), which affects the market.
How does the government control medicine prices in Ukraine?
The government sets maximum prices for medicines so they do not exceed a certain level, and monitors this through the Antimonopoly Committee.
What are price ceiling and price floor?
A price ceiling is a maximum price above which goods cannot be sold; a price floor is a minimum price below which goods cannot be set.
Why does a shortage occur under price controls?
If the government sets a price below the equilibrium, producers reduce supply while consumers want more, creating a shortage.
What is the green tariff in Ukraine?
The green tariff is a high price at which the government purchased electricity from solar panels, stimulating production.
