We start off firslty by reminding the general model for valuing assets. A well know accounting identity expresses the relation between the value of an asset, the income stream it generates and to which the holder of the asset is entitled ($C_{1}$,$C_{2}$, . . . $C_{n}$) and an endogeneous return $R$   \begin{equation}  V_{t}=\displaystyle\sum_{i=1}^{K}\frac{C_{t+i}}{(1+R)^i}+V_{t+K} V_{t}=\displaystyle\sum_{i=1}^{K}\frac{C_{t+i}}{(1+R)^i}+\frac{V_{t+K}}{(1+R)^K}  \end{equation}  In other words, $R$ is what you earn if you pay $V_{0}$, receive $C_{1}$,$C_{2}$, . . . $C_{K}$ and sell the asset at  $V_{K}$. $V_{t+K}$.  The value of the asset when you sell it is the terminal value of the asset. This basic principle is at the root of many equity valuation models; the \textit{DDM} is the exact translation of this accounting principle where dividends are the revenues a shareholder is entitled to. \subsection{The \textit{DDM}}
