I posted before about David Bell’s analysis of the Scottish referendum bookies odds. The bookmakers seemed to do a good job not overreacting to the late poll numbers showing a marked swing to Yes. The days before the referendum were throwing up some dramatic poll results but the odds did not adjust as dramatically, implying the bookies were either temporally averaging across polls, had some priors about the quality of the polls, or were doing a degree of Bayesian updating or something similar. David has provided a nice piece here for those looking to keep track of bookies odds for Brexit. For now, it looks like Stay is the favorite by quite a margin and more than one would think just by looking at opinion polls.
