Planned Number of Clusters
|
Before
40 restaurants. We may evaluate the treatment effects on the waiter level as it allows us to
account for individual fixed-effects. However, we do not know yet how many waiters will
work on the specific days.
|
After
35 Restaurants (We needed to remove 5 restaurants as they could not take part in the experiment. The reason is that we found out that they were part of a confounding change earlier that year. They already had implemented measures similar to the treatment in January, which we had not been informed of before.) We may evaluate the treatment effects on the waiter level as it allows us to
account for individual fixed-effects. However, we do not know yet how many waiters will work on the specific days.
