If aggregate demand increases while short-run aggregate supply remains constant, what is the likely effect on the Phillips curve?

When aggregate demand increases and short-run aggregate supply stays the same, it usually leads to higher prices and lower unemployment in the economy. This is because more people want to buy goods and services, so businesses respond by raising prices. As a result, on the Phillips curve, which shows the relationship between inflation and unemployment, we would see a movement along the curve towards higher inflation and lower unemployment. For example, if a new technology makes people want to buy more gadgets, businesses might raise prices due to increased demand, leading to a situation where we have both higher inflation and fewer people out of work. Overall, this shift illustrates the trade-off between inflation and unemployment in the short run.
