How would an increase in aggregate demand affect the Phillips curve in the short run?

An increase in aggregate demand means that people and businesses want to buy more goods and services. When this happens, companies may need to hire more workers to keep up with the higher demand, which can lead to lower unemployment. The Phillips curve shows the relationship between inflation and unemployment, and in the short run, when demand goes up, inflation may also rise because prices can increase as more money is spent. For example, if a new restaurant opens in town and attracts many customers, it may need to pay higher wages to attract workers, leading to higher prices for meals. Thus, in the short run, an increase in aggregate demand can lead to lower unemployment and higher inflation, shifting the position on the Phillips curve.
