I want to change the width of these three bars at the bottom of the beamer page, because the title bar width is not enough. How do I do that in LaTeX?

P.S. I'm using CambridgeUS Theme.

You have two solutions. The easiest one is to define a shorttitle for your presentacion.

\title[Inst. Variable Quantil Regression]{Instrumental Variable Quantil Regression}

When a short title is defined, this is what is shown in your footline, while the long title is shown in your cover. If you don't declare a short title, the long title is shown in footline.

But if you want to change foot width, you can do it with following code. It's the infolines footer definition, where .333 original widths have been adjusted to .25+0.5+0.25.


  \begin{beamercolorbox}[wd=.25\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\ifblank\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
  \begin{beamercolorbox}[wd=.50\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \begin{beamercolorbox}[wd=.25\paperwidth,ht=2.25ex,dp=1ex,leftskip=2ex,rightskip=2ex,sep=0pt]{date in head/foot}%
    \usebeamerfont{date in head/foot}%
    \usebeamercolor[fg]{page number in head/foot}%
    \usebeamerfont{page number in head/foot}%
    \usebeamertemplate{page number in head/foot}%
