Let $u:Z\rightarrow R$ be a utility representation of the DM's preferences over the elements of $Z$ as certain outcomes. (I.e., $u(y)\geq u(z)$ iff $y \geq z$.) \end{slide} \begin{slide} \heading{Expected utility \& the St.\ Petersburg Paradox} This can get around even St.\ Petersburg Paradox, because we don't require that utility be linear in money: \begin{center} \begin{tabular}{r|c|c|c|c|c}\cline{2-6} Prize & \$2 & \$4 & \$8 & \$16 & $\ldots$\\ \cline{2-6} $u(z)=\log_2(z)$ & 1 & 2 & 3 & 4 & $\ldots$ \\ \cline{2-6} Prob. & 1/2 & 1/4 & 1/8 & 1/16 & $\ldots$\\ \cline{2-6} \end{tabular} \end{center} Expected utility is $\sum_{k=1}^\infty k/2^k = 2$, and so lottery gives same expected utility as getting \$4 for sure. \end{slide} \end{document} %% END semsamp1.tex
