What is really ridiculous is that I didn't realize you don't need all
that, but just the plain old $...$; that is,

\documentclass{article}
\usepackage{amsmath}
\usepackage{longtable}
\begin{document}
\begin{longtable}{|p{14cm}|}
\hline
Hi\\ \hline\\[-8pt]
$a_{ig} = \begin{cases} 1 & \text{if customer$i$belongs to profile group$g$}\\ 0 & \text{otherwise} \end{cases}$ \\[12pt] \hline
\end{longtable}
\end{document}

Best,

Axel
