如果 .bib 条目包含 2 位以上的作者，是否修复 .bst 文件以显示“作者等（年份）”？

这个问题与这里的问题非常相关：

引用“et al.”仅适用于 natbib 和 jf.bst 中的四位或更多作者

在回答该问题时，Mico 展示了如何替换 jf.str 中的 format.lab.names 函数，以便当条目中有超过 4 位作者时，.bib 条目显示为“作者等（年份）”。但是，这是针对 nyu.edu 网站上的 jf.str 版本完成的。我希望能够使用此处的 .str 文件实现相同的行为

http://pages.stern.nyu.edu/~dbackus/GE_asset_pricing/BGTZ/jf.bst

尽管名称相同，但经过一些修改以适合计量经济学 (Econometrica) 的参考书目要求。

所以问题是，有人能向我解释为什么当我用 FUNCTION {format.lab.names} 替换

FUNCTION {format.lab.names}
{'s :=
 "" 't :=
  #1 'nameptr :=
  s num.names$ 'numnames :=
  numnames 'namesleft :=
    { namesleft #0 > }
    { s nameptr
      "{vv~}{ll}" format.name$
      't :=
      nameptr #1 >
        {
          nameptr #2 =
          numnames #2 > and
            { "others" 't :=
              #1 'namesleft := }
            'skip$
          if$
          namesleft #1 >
            { ", " * t * }
            {
              s nameptr "{ll}" format.name$ duplicate$ "others" =
                { 't := }
                { pop$ }
              if$
              t "others" =
                { " et~al." * }
                {
                  numnames #2 >
                    { "," * }
                    'skip$
                  if$
                  bbl.and
                  space.word * t *
                }
              if$
            }
          if$
        }
        't
      if$
      nameptr #1 + 'nameptr :=
      namesleft #1 - 'namesleft :=
    }
  while$
}

每当 .bib 条目有超过 2 位作者时，我都不会得到“作者等（年份）”。（我意识到这可能很简单，并开始阅读 Tame the Beasthttp://www.lsv.ens-cachan.fr/~markey/BibTeX/doc/ttb_en.pdf）。 谢谢。

现在您已经向我们指出了bib要修改的正确样式，下面是一个更短的替换format.lab.names：

FUNCTION {format.lab.names}
{ 's :=
  s num.names$ 'numnames :=
  s #1 "{vv~}{ll}" format.name$
  numnames #1 >
    { s #2 "{vv~}{ll}" format.name$ 't :=
      numnames #2 >
      t "others" =
      or
        { " et~al." * }
        { " and " * t * }
      if$
    }
    'skip$
  if$
}

在您的示例文件（略微整理，见下文）中，它会产生

示例输出

该函数的工作原理如下。首先将作者列表存储在 中s。将作者数量存储在 中numnames。格式化第一个（#1）条目并输出。然后，如果有多个名称，则格式化下一个名称并将其分配给t。如果t是"others"或实际上有两个以上的作者，则输出et al.，否则输出 前面的第二个（最后一个）作者and。
