Professor Papke kindly provided these data. She gathered them from the Internal Revenue Service&lt;U+2019&gt;s Form 5500 tapes. Data loads lazily.

datasets

Students learning both econometrics and R may find the introduction
to both challenging. The wooldridge data package aims to lighten the task by efficiently
loading any data set found in the text with a single command. Data sets have been
compressed to a fraction of their original size. Documentation files contain page numbers,
the original source, time of publication, and notes from the author suggesting avenues for
further analysis and research. If one needs an introduction to R model syntax, a
vignette contains solutions to examples from chapters of the text.
Data sets are from the 7th edition (Wooldridge 2020, ISBN-13: 978-1-337-55886-0),
and are backwards compatible with all previous versions of the text.

k401k function

A data.frame with 1534 observations on 8 variables:<ul>
<li>prate: participation rate, percent</li>
<li>mrate: 401k plan match rate</li>
<li>totpart: total 401k participants</li>
<li>totelg: total eligible for 401k plan</li>
<li>age: age of 401k plan</li>
<li>totemp: total number of firm employees</li>
<li>sole: = 1 if 401k is firm's sole plan</li>
<li>ltotemp: log of totemp</li>
</ul>

Format

This data set is used in a variety of ways in the text. One additional possibility is to investigate whether the coefficients from the regression of prate on mrate, log(totemp) differ by whether the plan is a sole plan. The Chow test (see Section 7.4), and the less restrictive version that allows different intercepts, can be used.
