The price level going up a lot is called inflation, and when there are more people looking for jobs than there are jobs available, that's unemployment. To keep the economy healthy, it's important to have both low inflation and low unemployment. In the European Union, when inflation goes down, unemployment often goes up, and when unemployment goes down, inflation may go up. This means there's a strong connection between the two, but they move in opposite directions. The researchers in this article looked at how inflation and unemployment are related in the European Union.
