Econometric Analysis of Cross Section and Panel Data

By Jeffrey Wooldridge

Official site for downloadable materials

Provided here are the datasets that were used to produce the output in the book Econometric Analysis of Cross Section and Panel Data by Jeffrey Wooldridge.

You can download the datasets from within Stata using the net command. At the Stata prompt, type

       . net from http://www.stata.com/data/jwooldridge/
       . net describe eacsap
       . net get eacsap
This will download all files associated with the book to your current directory.

If you do not have an Internet connection from within Stata, you can download one of the following files:

eacsap.zip ZIP format, 2MB
eacsap.tar.Z Unix tar.Z format, 3MB

We suggest you create a new directory and copy the materials there.

The book sometimes refers to filenames using capital letters. Due to differences across operating systems, the filenames stored here are all lowercase.

In addition to the methods above of obtaining all files associated with the book at once, it is possible to use any individual file from within Stata. Simply click on a file in the list of datasets below to download it to a local folder on your machine, or from within Stata, type

        . use http://www.stata.com/data/jwooldridge/eacsap/filename
where filename is the name of the dataset in the book, typed as all lowercase without the extension. For example, on page 59, the file MROZ.RAW is discussed. For ease of use, we have made this data available in Stata format as mroz.dta. To load the dataset into Stata, type
        . use http://www.stata.com/data/jwooldridge/eacsap/mroz
Many users find it convenient to define a macro to the path so that files can be obtained with less typing:
        . global JW http://www.stata.com/data/jwooldridge/eacsap
        . use $JW/mroz
