问号代替引用/扩展问题

我在生成参考文献时遇到了麻烦。对于某些引文，文件会生成问号而不是作者姓名。我尝试了本论坛中的建议，并且已经知道了“编译 - 双重编译”过程，但没有进展。

有人能帮我吗？

这是我的代码的部分内容

书目文件包含以下条目

@TECHREPORT{ Perotti2008,
title = {In Search of the Transmission Mechanism of Fiscal Policy},
author = {Hill, Scott and Wootters, William K.}
booktitle = {NBER Macroeconomics Annual 2007",}

@ARTICLE{Papageorgiou2012,

  journal = {Journal of Macroecnomics},

  owner = {Minamar},

}

答案1

正如 Ulrike 在她的评论中所说，您的bib文件中存在一些错误。

稍微解释一下：bib文件的每个条目都必须像这样构建：

@literature{key,
  name  = {value(s)},
  name1 = {value(s)},
  ...
  namen = {value(s)}
}

literature可以是book,article等等，key是引用键，name代表字段条目的名称，如author,title等等，并value(s)表示字段条目的值、作者姓名、书名等。每行都必须以逗号结尾（} 之外），除了最后一行，您可以在那里写逗号或不写逗号。如果不写逗号，添加新行时通常会导致错误。

因此，您修正的文件部分bib经过了一些漂亮的打印，看起来应该像您在更新的 MWE 中看到的那样。

更新：

以下 MWE 在我的系统上运行没有任何错误或警告：

\RequirePackage{filecontents}           % allows overwriting of file

\end{filecontents*}

\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc} 

\usepackage[round]{natbib}
\usepackage{hyperref}

\begin{document}
\section{Introduction}
For a survey see \citet{Perotti2008} who~\dots
A leading example is \citet{Papageorgiou2012} who~\dots
%\nocite{*}   % all entrys in bibliography to test the bib file

\bibliographystyle{plainnat}
\bibliography{\jobname}
\end{document}

使用此示例测试您的bib输入。只需复制一进入 MWE 并再次运行（记住：三次）。

更新 2：

我在 MWE 中添加了两条更正过的参考书目条目。文章条目的Edenber1999作者字段有很多问题。我尝试更正它。请自行检查。条目Leeper2008显示了另一个问题：将作者写成“姓名，名字”或“名字名称”。不要混淆。最好包括作者的完整名字。查看作者杨（空白缺失：S. Yang？）。不要使用\&而不是and。
