Now, economic impact studies always require some value judgments, especially when it comes to that add-on spending, which often assumes (and I am simplifying) that a waiter gets an additional shift because “Hamilton” has a matinee. If that waiter goes out for a drink that night using those tips, then that spending is fair game, because it would not otherwise have occurred, being as our lucky waiter would not have enjoyed that cash infusion. It’s likely that storefront shows generate fewer hotel nights than “Hamilton.” I’d also note that the Donnelly population of storefront theaters included in those 267,400 patron admissions is not the entire population of storefront theaters, a diverse set of arts organizations that always has been near impossible to define — for example, given that many storefronts do not use union artists, where does professional theater end and community theater begin?
