答案1

很难猜出这\medium是什么意思。但是你有几个东西是不必要的。

\documentclass{beamer}

\newcommand{\medium}{???}

\begin{document}

\begin{frame}
\frametitle{Empirical specification}

We employ the quasi-exogenous variation of an In-laws death
\[
\medium{
  Y_{it}=\alpha_{i} + \omega_{dt} +\beta\, inlawdeath_{i} \cdot post_{it}
  +\theta\,post_{it} +\rho X_{it}+\epsilon_{it}
}
\]

\begin{flushleft}\scriptsize

$Y_{it}$ = Health outcome (BMI/IU) of women ${i}$ in survey round ${t}$

$inlawdeath_{i}$ = indicator equal to one if the DIL ${i}$’s 
PIL died

$post_{it}$ = Indicator when considering data from wave 2

$\alpha_{i}$ = Individual Fixed Effects

$\omega_{dt}$ = District Survey Fixed Effects

$X_{it}$ = Time-varying controls

\end{flushleft}

\end{frame}

\end{document}

请注意我删除了全部 \vspace声明，并且也\RaggedRight没有任何用处，用flushleft声明代替它\scriptsize。

\,还要注意，当长“变量名”旁边是另一个符号时，空格会很窄。

切勿$$在 LaTeX 中使用。并避免使用无用的括号。

图像

但结果还是有点局促。也许\footnotesize会更好。

答案2

我建议使用align*环境来列出变量的含义。

在此处输入图片描述

\documentclass{beamer}

\begin{document}

\begin{frame}{Empirical specification}
We employ a quasi-exogenous variation of an in-law's death:
\[
Y_{it} = \alpha_{i} + \omega_{dt} + \beta\,inlawdeath_{i}\cdot post_{it}
  + \theta\,post_{it} + \rho\,X_{it} + \epsilon_{it}
\]
where\small
\begin{align*}
Y_{it} &\quad \text{Health outcome (BMI/IU) of woman $i$ in survey round $t$} \\
inlawdeath_{i} &\quad \text{Indicator equal to 1 if DIL $i$'s PIL died} \\
post_{it} &\quad \text{Indicator when considering data from wave~2} \\
\alpha_{i} &\quad \text{Individual fixed effects}\\
\omega_{dt} &\quad \text{District survey fixed effects}\\
X_{it} &\quad \text{Time-varying controls}
\end{align*}

\end{frame}

\end{document}
