I said assuming OLS – I’m assuming iid Normal errors. And my multiple regression model is incomplete, almost certainly. Don’t be a trouble-maker.

Everyone else, Pete (former office-mate, so I can call him names freely, the jerk) is referring to selection bias (probably correctly). If people are electing to become fan club members for the purpose of getting tickets, there is the distinct possibility that they are going to make more of an effort.

There is, however, also the possibility that being members generates ticket-securing-complacancy: perhaps they made less effort.

Either way, the OLS assusmption that the error terms are independent and identicically distributed breaks down: the errors make be structural, meaning correlated with the explanatory variables.

E.g., suppose systematically more variance is observed in one membership category than the other; or, as Pete said, some third variable is explaining both one’s success at getting a ticket and one’s membership in the fan club – call it Initiative. This is a very hard thing to go out and measure.

I never defended Economists. I would remind Pete, though, that simple Economics has already explained both how this problem arose, and why, and what might easily have been done to prevent it, or correct it after the fact. The problem here wasn’t economics, it was ‘hurricane people’ and class-action litigation firms …

Plus, 3 years ago, he was the one giving me stick for not calling myself an Economist. Pete: do give my regards to those roosting chickens you’ve got coming home.

What if membership is endogenous? Fans who become members might be more likely to ‘try harder’ to get the tickets. They will make sure they know the exact date tickets are on sale, refresh their web browser more times trying to get to the tickets page. Some of these things might be in your control variables, but maybe more are unobserved, biasing beta1 upwards.

Economists *pretend* econometrics can solve anything!
