A quota is a cap on how much stuff (like corn or steel) a country can import. Think of it like a bouncer at a club saying, "Sorry, only 2.68 million tons of steel from Korea can come in here!" It's a way for a country to control its market.

Real-World Example: In 2018, the USA put a quota on Korean steel imports. Imagine if you could only eat 21% fewer cornflakes for breakfast. That's kinda what happened to the steel industry!

Here's a fun-filled step-by-step guide to understanding how quotas affect a market using corn as an example

 Before Quota

• Price: World price for corn (Pw)
• Domestic Supply: Farmers offer Q1 units of corn
• Domestic Demand: Consumption is Q2 units
• Imports: Difference between demand and supply, Q2 - Q1 (aka af units)

Imagine unlimited corn at a global carnival - eat all you want at price Pw!

 After Quota

• Government's Move: Limit corn imports from af to ab units
• Domestic Price: It's like a tug-of-war, pulling the price up!
• Effective Supply: Domestic corn (Q1) + the fixed quota amount (ab)
• New Equilibrium Price: Where supply meets demand at P'
• New Supply and Demand: Farmers offer Q3, buyers want Q4, imports = Q3Q4 (the quota)

It's like limiting the number of corn dogs at the fair. Fewer corn dogs, higher prices!

• Before Quota: Farmers earn Pw * Q1; Consumers spend Pw * Q2; Import expenditures are Pw * Q1Q2
• After Quota: Farmers earn more; Consumer spending depends on price elasticity of demand (PED)

Picture your pocket money. Less spending on video games might mean more for candy! 🎮🍬
