Okay kiddo, so you know how we live in different places, and some places have more resources or jobs than others?
There are some people who study why that happens, and they put their ideas and findings in a special book called the Journal of Economic Geography.
They try to figure out why some places are really good for businesses, like having lots of land or lots of people, and some places aren't as good. They also look at how different places are connected to each other, like with roads or airports or internet, and how that affects their economies.
So basically, the Journal of Economic Geography is like a really big book where smart people write down all their ideas about why certain places are rich or poor, and how we can make things better for everyone.
