Abstract
This study will examine the business practices among small-sized retail firms in urban Jakarta using a randomized controlled trial (RCT) methodology. The project will have three main goals. First, we will characterize the business practices used by the retailers, identifying those that are potentially conducive to productivity growth, higher sales and profits. Second, we will disseminate the top performance-enhancing business practices among the retailers and will track the adoption of such business practices by retailers. Third, we will study the causal effect of adopting the business practices on business performance and growth. In order to distinguish informational and behavioral constraints to adoption of the practices, we will vary the ways in which the information is conveyed and implemented. To that end, we will make use of different framings as well as business role-models in the implementation of the practices.

Experimental Details
Interventions
Intervention(s)
There are three arms of intervention in this study. Out of the 1300 retailers that will have been both listed and interviewed in the run-up to the intervention, 1000 will be chosen at random by the Research Team to be subjected to various treatments outlined in the following.

First, all 1000 shop owners will receive a handbook with business practices that successful retail entrepreneurs in Jakarta have been found to employ. There will be two types of handbooks: one handbook with gains framing and another with losses framing. While the former will show the possible increase in profits and sales as a result of implementing the business practices, the latter will show the possible losses associated with the non-adoption of the practices. These handbooks will be randomly assigned to shop owners, so that 500 shop owners receive the “gains framed” handbook and 500 shop owners receive the “losses framed” one.

Second, out of the above mentioned 1000 shop owners, we will invite a randomly selected 500 to public viewings of a documentary that will star some selected shop owners from Jakarta describing the business practices they view as crucial, as well as the practical steps they took to implement these practices and grow.

Third, another 500 retailers, also to be selected at random from the aforementioned 1000, will receive assistance in the implementation of suggested practices.

There are three arms of intervention in this study. Out of the 1300 retailers that will have been both listed and interviewed in the run-up to the intervention, 1000 will be chosen at random by the Research Team to be subjected to various treatments outlined in the following.

First, All 1000 shop owners will receive a handbook with business practices that successful retail entrepreneurs in Jakarta have been found to employ. There will be two types of handbooks: one handbook with gains framing and another with losses framing.

Second, out of the above mentioned 1000 shop owners, we will invite a randomly selected 500 to public viewings of a documentary that will starr some selected shop owners from Jakarta describing the business practices they view as crucial, as well as the practical steps they took to implement these practices and grow. Acting as role models, these peers, along with their unique success stories and hands-on advices, may serve as an exemplar and therefore foster growth by opening up aspiration windows and facilitate the adoption of successful practices.

Third, another 500 retailers, also to be selected at random from the aforementioned 1000, will receive assistance in the implementation of suggested practices. To this end, the facilitator personnel will each be clearly assigned to visit a sub-sample of shops once in the first week for the duration of about one hour. This visit will be followed up by weekly calls of about 15-20 minutes for a period of 3 weeks. During these visits facilitators will help shop owners implement selected business practices within their unique working environment, will answer business owners’ questions or else report back to the Research Team to address the owners’ concerns during the follow-up calls.
