The COMPASSS Working Papers series publishes work-in-progress with a connection to configurational comparative methods such as crisp-set QCA, multi-value QCA, fuzzy-set QCA, and linked methods and techniques. The WP series was instituted in 2002 as an informal forum to publish work-in-progress and re-launched in 2009 as a peer reviewed working paper series.  If you would like to publish your working paper in the WP Series, please visit the COMPASSS web site.
