Real vs nominal Profit=p*Y-W*L一r*K Y=MPL*L+MPK来K W(r: return to L(K)in terms of money(nominal) MPL (MPK): return to L(K)in terms of products(real)
Real v.s. Nominal Profit = p * Y – w * L – r * K Y = MPL * L + MPK * K W ( r ):return to L (K) in terms of money (nominal) MPL (MPK):return to L (K) in terms of products (real)
