[Tex/LaTex] putting tikzpicture inside beamer

beamertikz-pgf

I am trying to add tikzpicture inside Beamer. However, I cannot use such functions as \pause, enumerate etc with TikZ.

Here is what I got thus far. I would like to change the enumerate environment and \pause after each point.

\documentclass{beamer}
%\usecolortheme{beaver}
\usepackage{textpos}
\usepackage{comment}
\usepackage{tikz}
\usepackage{graphicx}
%\usepackage[a4paper,left=2.0cm, right=2.0cm, top=4.5cm, bottom=2.5cm]{geometry}
\usetikzlibrary{snakes}

\begin{document}

\begin{frame}{Time Line of the Model}


\begin{tikzpicture}
 %draw horizontal line
 \draw (-2,0) -- (10,0);

 %draw vertical lines
 \foreach \x in {-1.5,3,8}
   \draw (\x cm,3pt) -- (\x cm,-3pt);

 %draw nodes
 \draw (-1.5,0) node[above=3pt] {$ 0 $};
 \draw (3,0) node[above=3pt] {$ 1 $};
 \draw (8,0) node[above=3pt] {$ 2 $};

\small
\node[align=left, below] at (0,-.5)%
{
1) The board of directors \\ offers the manager a \\ contract ($\omega_0, \omega_p, \omega_v$).\\\\ 
2) The short-term $v_S$, \\and the long-term $v_L$  \\ projects are initiated \\ by the manager.\\\\
3) The manager is \\ (partially) compensated \\ a fixed wage of $\omega_0$.\\\\
4) The IPO price of the \\stock  $p_0$ is determined \\by the investors
};


\node[align=left, below] at (4.5,-.5)%
{
1) Speculators observe\\ costly noisy signals $\theta_S $ \\ and $\theta_L)$ of the value of \\ short- and long-term \\ project. \\\\
2) The market for the firm's \\ shares opens for trade;\\ and the resulting market \\ price is $p$.\\\\
3) The manager is \\ (partially) compensated \\ an amount of $\omega_p p$.
};


\node[align=left, below] at (8.5,-.5)%
{
1) The terminal value \\of the firm $v$ is realized.\\\\
2) The manager is \\  (partially) compensated \\an amount of $\omega_v v$.
};
\end{tikzpicture}
\end{frame}
\end{document}

I would use the columns environment to split your page; the tikzpicture works well for the line across the top, but there's no need to use it for all of the other parts.

Note that the columns environment takes an optional argument to specify the vertical alignment; I've used [t] for top. The environment allows you to specify each column using 

\begin{column}{<width>}
    content
\end{column}

which I have done, and changed all of your manual lists to enumerate. You can now add \pause at the end of each \item and get the display you want :) See section 12.7 of the documentation for more details.
