This study investigated the endogenous relationship between the differences in cost efficiency and hotel owners' choices of either remaining an independently operated establishment or joining an international chain. We applied observations of 72 international tourist hotels in Taiwan from 1997 to 2008 to a simultaneous equations model with qualitative and limited dependent variables. The study results suggest that joining international chains significantly improves cost efficiency. We also found that net gains from improving both cost efficiency and hotel location are the two foremost determinants for an owner's decision to join an international hotel chain.
