Market equilibrium is like the perfect balance where the amount of products people want matches what sellers can offer. This is the point where prices for goods and services are just right—not too high and not too low. When this balance is achieved, it helps everyone: it makes things work better for consumers and supports businesses.

But sometimes, the government steps in and makes rules about prices. These rules can be either price ceilings or price floors.

Price Ceilings:

• Example: Rent control
• Pros: Helps keep basic needs affordable
• Cons: Can cause shortages because more people want housing than is available

Price Floors:

• Example: Minimum wage
• Pros: Makes sure workers earn enough money
• Cons: Can lead to too many workers with not enough jobs, causing unemployment

The way these rules affect economic policy is very important. Governments need to find a balance between the good things these rules bring and the problems they might cause. For example, while trying to make things fair and stable, they can accidentally upset that perfect balance and create issues in the market.

So, it's really important for policymakers to think about how these rules will affect everyone before they put them in place. Getting this balance right can either help or hurt the economy, influencing everyone from local shops to everyday people. It's a tricky situation!
