The Long Run Philips curve is not effected by AD or AS which is why its a straight line. It represents the natural rate of unemployment over a given time. Think of it this way, If AD were to shift to the right Then the Price level would increase thereby making products more expensive to make. If products are more expensive to make then less of these products can be created Ergo AS shifts to the left. Now if you were to draw out the following example you would see that these shifts in AS and AD returned the graph to the natural rate of unemployment QF. Good luck on Mr Goffman's test tommrow btw.
When economists look at inflation and unemployment in the short term, they see a rough inverse correlation between the two. When unemployment is high, inflation is low and when inflation is high, unemployment is low. This has presented a problem to regulators who want to limit both. This relationship between inflation and unemployment is the Phillips curve. The short term Phillips curve is a declining one. Fig 2.4.1-Short term Phillips curveThis is a rough estimation of a short-term Phillips curve. As you can see, inflation is inversely related to unemployment. The long-term Phillips curve, however, is different. Economists have noted that in the long run, there seems to be no correlation between inflation and unemployment.
The key difference between the long run supply curve and the short run supply curve in economics is that the long run supply curve is more elastic and flexible, as firms can adjust their production levels and resources in the long run. In contrast, the short run supply curve is less elastic and more rigid, as firms have limited ability to change their production capacity in the short term.
what is the relationship between long run average cost curve and short run average cost curve?
The Phillips Curve is the negative relationship between unemployment and inflation. If you want to have less unemployment the cost is inflation. In this sense, you can also say that there is a positive relationship between output and inflation, because output is negatively correlated with unemployment (firms need workers to produce more). The first thing you have to kept in mind is that the Phillips relation is only true for shocks in Aggregate Demand. For instances, when the U.S. suffered from stagflation on the 70s (inflation and low output - or inflation and higher unemployment) the evidence showed that not always the Phillips curve are right. In this case, the oil shocks affected suppliers costs and thus the Aggregate Supply. Given this, the Phillips Curve holds in the short-run for any shock on AD. In the long-run the production (unemployment) of an economy depends on its inputs abundance and their efficiency, independently of the nominal variables (like prices, inflation, etc.). So the Phillips curve is an horizontal line, the natural unemployment is independent of the inflation! Gustavo Almeida, Portugal, gdireitinho@gmail.com
in the short run, there is an inverse relationship between the rate of unemployment and the rate of inflation. In the long run it is nonexistent because employment will always be at full employment thus the only factors able to shift the Phillips curve left or right would be decreases or increases in LKT(labor, capital, technology.)

Yes. Inflation causes businesses to have to cut costs, and labor is one of the easily cuttable costs. See the Phillips Curve.

in the short run, there is an inverse relationship between the rate of unemployment and the rate of inflation. In the long run it is nonexistent because employment will always be at full employment thus the only factors able to shift the Phillips curve left or right would be decreases or increases in LKT(labor, capital, technology.)
the long term is different between a short term because the short
The short term aggregate supply curve represents the relationship between the price level and the quantity of real GDP that firms are willing to supply in the economy. It shows the level of output that firms can produce in the short run at different price levels.
nothing
There is no difference. Limo is just short for limousine.
