Abstract
Previous studies have shown that behavioral nudges can be a cost-effective tool to influence changes in people’s actions. In this study, we aim to test whether nudging court managers through informing them on how their court performs in absolute and relative terms can improve court productivity. Moreover, we test if there is any difference if the information about the court performance is given in contrast and relation to self past performance or if the information is relative to other courts' performance.

Primary Outcomes

Primary Outcomes (end points)
Case clearance rate, average length for filing cases (days), average length for ending cases, the average time the court needs to provide a written submission during the consultation period, percentage of writing resolved with 3-5 days, average number of days to program a hearing, percentage of hearing that started with a delay of 15 minutes, percentage of cases pending for more than 1-2 years, appeal rate, and number of cases appealed.

On the promotion intervention, the main primary outcome is number of logins per court manager to the Quantum platform
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Court managers job satisfaction
Secondary Outcomes (explanation)
The court managers' job satisfaction level will be taken from the pre and post-surveys to court managers that measure perceptions of their tribunals and their satisfaction with their positions. By informing the court managers about their court's standing it could change how empowered or satisfied a court manager is with his or her position and power role.

Experimental Design

Experimental Design
The program will have six distinct treatments. The treatments will combine promoting the usage of an electronic platform that contains information on their court performance and providing distinct homepages in this platform that will summarize the courts performance stressing the weaknesses and strengths of the court in comparison to a reference group.
Experimental Design Details
First, we will (randomly) promote the Quantum platform in multiple ways, such as sending court managers a survey that implicitly markets the platform, making phone calls, and sending them emails. Second, we will (also randomly) provide court managers a new dashboard that summarizes the main statistics displayed in Quantum and compares them to themselves in the past or to a reference group of courts. There would be a total of six treatments: (0) no quantum promotion no new dashboard (control) (1) quantum promotion, (2) no quantum promotion and new Quantum dashboard, (3) quantum promotion and a new dashboard, (4) no quantum promotion, new dashboard, and comparative that emphasizes the strongest and weakest indicators for that month in comparison to a similar group of courts in that same month, and (5) quantum promotion, new dashboard, and comparative that emphasizes the strongest and weakest indicators for that month in comparison to a similar group of courts in that same month.

Given that the information in the Quantum platform is updated daily and our dashboards are updated with monthly data, we will have multiple pre-treatment observation and many post-treatment observations.
Randomization Method
Randomization done in office by a computer.
Randomization Unit
The unit of randomization is the court. The randomization was stratified by size (small and big) and court type (7 distinct ones).
Was the treatment clustered?
No
