Abstract
This trial investigates the effect of leader incentives on the performance of teams. In collaboration with a medium-sized Latin-American bank, we engineered a field experiment by designing a series of contests among the bank branches, in which we varied the prize structure of the tournaments (in some tournaments, the prizes were shared among all branch employees, while in other tournaments there was an additional prize for the branch manager).

Experimental Design

Experimental Design
In collaboration with a medium-sized Latin-American bank, we engineered a field experiment by designing a series of contests among the bank branches, in which we varied the prize structure of the tournaments (in some tournaments, the prizes were shared among all branch employees, while in other tournaments there was an additional prize for the branch manager).
Experimental Design Details
From September to December of 2014, each of the 177 branches of the bank competed in four monthly tournaments. Each month, the branches were randomly allocated to one of seven tournaments of about 25 branches each. At the beginning of each month, the allocation, as well as the structure of prizes for the month and other rules of the contest, were announced to the entire branch network through the bank’s intranet. At the end of the month, the top three branches in each tournament received a prize to be shared among all branch employees.
Throughout the four months, branch employees participated in the tournament, but were unaware that the tournaments were part of a field experiment.
We use a within-subject field experiment where the factors are leader bonus and leadership style. Leader bonus is an exogenously manipulated factor that refers to the presence or absence of an additional bonus to the team leader, and leadership style is a measured factor that refers to the transactional versus transformational style of the leader.
We implemented the leader bonus manipulation as an exogenous change where an individual prize was awarded to the leader of the winning branches during two of the tournament months: October and December. We selected the months with a leader bonus randomly.
Randomization Method
Both randomizations were done in the office by a computer.
Randomization Unit
For the tournament groups the unit of randomization was the branch.
For the leadership additional bonus the unit of randomization was each combination of four months with two pairs of treated and untreated months.
Was the treatment clustered?
No
