What are policy lags?

Policy lags are like when you ask for help and it takes a little while before things get better.

Imagine you're playing on the swings at the park, and your friend is pushing you higher and higher. But one day, the swings start to creak and wobble, they’re not as strong anymore! You tell your friend, "Hey, the swings are broken!" So your friend runs off to get a grown-up to fix them. But it takes time for the grown-up to come, and even longer for them to fix the swing.

That delay between when you notice the problem and when it's fixed is like policy lags, the time it takes for a decision (like fixing the swings) to actually happen and make things better.

In real life, policy lags can be like when a country decides to do something about prices going up. The government might take a while to notice, then a while more to make changes, just like it took time for your friend to get the grown-up and fix the swings.

Sometimes things are even slower, like waiting for a new road to be built or for a new rule to start working. That’s why it's important to plan ahead!
