It is a foregone conclusion at times, that it is always the victory of the heart that is inevitable in the battle between the heart and the mind.

## The aggregate supply: AS curve

Our analysis of production starts with the micro-foundations of macroeconomics that the neoclassicals so greatly achieved. A main facet of such a concept is the quasi-concave short-run neoclassical production function, which is defined as, \(Y = F(N,\bar{K})\) which incorporates the rigidity of the level of capital in the economy. The firm’s maximisation problem therefore must be written as $$\max_{N} PY-WN$$ and substituting with the available function for production, we arrive at $$\max_{N} PF(N,\bar{K})-WN$$ which enables us to arrive at the first order conditions (FOCs) given by \(PF_{N}(N,\bar{K})-W=0\). This result could also be written as, \((W/P)=F_{N}(N,\bar{K})\) with the interpretation being that the households get paid the marginal product of labour as the real wage that is supplied by them. Differentiating the latest equation further with respect to \(N\) and \(\bar{K}\) yields:

$$d(W/P)=F_{NN}dN^D+F_{N\bar{K}}d\bar{K}\textrm{, or}\newline

dN^D=\frac{1}{F_{NN}}d(W/P)-\frac{F_{N\bar{K}}}{F_{NN}}d\bar{K}$$

I sometimes wonder what life would be like if I was someone completely different from who I am right now. It is a daunting proposition, but an intriguing one all the same.
