The nature of the aggregate supply curve in the long-run can be explained in the following steps:

1. Role of Pe: Pe stands for the expected price level. In the short run, firms form expectations about the price level, and these expectations influence their decisions about how much to produce at any given price level. If the actual price level turns out to be higher than expected, firms will increase their output, shifting the short-run aggregate supply (SAS) curve to the right. Conversely, if the actual price level is lower than expected, firms will decrease their output, shifting the SAS curve to the left.

2. Shape of the AD Function: The aggregate demand (AD) function is downward sloping, meaning that as the price level falls, the quantity of goods and services demanded increases, and vice versa.

3. Long-Run Aggregate Supply Curve: In the long run, however, the aggregate supply curve is vertical. This is because in the long run, the economy's output is determined by factors such as labor, capital, natural resources, and technology, rather than by the price level. This means that in the long run, changes in the price level do not affect the level of output. This is known as the classical dichotomy.

4. Implication: The implication of this is that in the long run, the economy is self-correcting. Any deviation from the natural level of output is temporary. For example, if the economy is in a recession with high unemployment, in the long run, wages will fall, reducing firms' costs and increasing the quantity of goods and services supplied. This will shift the SAS curve to the right, moving the economy back to its natural level of output.

In conclusion, the nature of the aggregate supply curve in the long run is vertical, implying that the economy's output is determined by factors other than the price level and is self-correcting in the face of deviations from the natural level of output.
