The data used in this paper come from two sources. The main source is
the Multiple Listing Service (MLS) in a large North American
metropolitan statistical area. Due to a confidentiality agreement to
access the MLS data, however, I cannot share the data with anyone
else, and I am not allowed to reveal the identity of the MLS and the
geographic area covered by this MLS. Nevertheless, the MLS data from
most areas contain very similar information, and more researchers have
gained access to the MLS data from other areas (e.g. Levitt and
Syverson, 2008a; Hendel, et al., 2009; Barwick, et al., 2017). Please
refer to these papers on how the MLS data can be accessed. 

The second source is the transaction data from CoreLogic. The license
agreements with CoreLogic do not permit me to make the data available
here. The contact information for Corelogic is

The estimation codes include three files. MLE_listing_selling.do is
do-file producing the results for the main model of the paper. This
file also includes the definition of variables used in the estimation.
lnL_rL.ado and lnL_rL_tobit.ado provide the likelihood functions. All
files are ASCII files in DOS format. They are zipped in the file
shh-files.zip.
