Pandora's groove: analysing the effect of the U-groove ban on PGA Tour golfers' performances and strategies

This study examines how PGA Tour golfers' playing strategies offset a ban on technologically superior golf club grooves and how the strategy changes translated into performance changes. The ban, which was implemented at the beginning of the 2010 season, effectively decreased golfers' abilities to spin the golf ball from all on-course environments and offers a unique opportunity to examine offsetting behaviour in the light of a ban on the type of technology. We compare 2009 and 2010 PGA Tour results in a manner consistent with previous studies of offsetting behaviour and golf club groove construction. Our results suggest that offsetting behaviour mitigated the effects of the technological regulations on golf clubs in an economically and statistically significant way, as golfers' performances improved following the technological ban.
