Other stuff:


Datasets often give us country names without the corresponding country code (ccode).  This makes it a total pain to merge with other datasets.  I’ve written a do file that will automatically fill in the ccode.  To add the country codes, first rename the country variable to “country” (probably unnecessary – it’s likely already named “country”).  Next, add the following to your Stata command line:




The command should generate a new variable called “ccode” with the correct ccodes.  I update the do file every time I see a country spelled a different way.  Please let me know if you find any errors or omissions (


In case you’re using R or something like that, it’s probably easiest to just merge in the ccodes.  For that, use the excel version here (though I haven’t updated it yet with the changes needed for Gleditsch/Ward or Polity).
