\section{INTRODUCTION}
In this paper I estimate the link between shareholder wealth and CEO salary. There has been much interest in this topic for almost a century, albeit mixed empirical results. In firm theory, optimal contracting views executive compensation as designed to minimize the agency costs that exist between executives and shareholders. The so called principle-agent problem arises when executives, the agents, act out of self interest and engage in activities that do not benefit the shareholders, or principles. Estimating the pay-performance sensitivity is fundamental to anyone questioning the size of CEO paychecks or wondering if they are paid enough.

这是一个解决方案，可将数字的小数点对齐。希望这能让表格内容更易于阅读。
关于 tabularx 代码：左列的列具有类型l，四个数据列具有类型S（由包定义siunitx）。为了使其在框架内“工作” tabularx，数据列上的四个标题为（已修改）类型X。

附录为了解决 OP 的评论，即把他的序言和我的序言结合起来会产生一个选项类：将你标记为“Mico 的代码”的内容移动到前面，并注意不要多次加载包，这样可以消除所有冲突：
