In particular, explain whether and in which direction each of the building blocks of LRAS and SRAS viz., labor supply (N3), labor demand (Nd), capital supply (K s) , capital demand (Kd) , and the production function as well as the aggregate supply (AS) curves themselves may shift in reSponse to the changes below.
