I suspect that the PDF states the authors' positions when the paper was written and the SSRN page states their current positions.

According to http://www.michaelmakowsky.com/about/ Michael D. Makowsky is currently a professor at Clemson University (as listed on the SSRN page) and was previously a professor at the Center for Advanced Modeling at Johns Hopkins University (as in the PDF).
