Abstract
We conduct a randomized controlled trial in a Bangladeshi garment factory in which randomly selected workers are invited to discuss suggestions for improvement over lunch with a randomly selected co-worker who is either a friend or a non-friend. We analyse the extent to which firm-related and worker-related outcome variables differ between pairs and individuals. Furthermore, we aim to answer the question whether the distribution of the quantity and quality of suggestions can be shifted upwards by active management such as giving recognition and feedback to employees.

Experimental Design

Experimental Design
In this project, we are working with a sample of ca. 200 operators working on one floor in a Bangladeshi garment factory. Pairs of workers will be randomly allocated to three groups
1) Friend pairs: Joint lunch with co-worker who is a friend
2) Non-friend pairs: Joint lunch with co-worker who is not a friend
3) Control group
Besides, pairs will be randomly allocated to another treatment group receiving feedback and recognition by managers. We will administer baseline, midline and endline surveys to collect measures of collaboration, job satisfaction, and idea generation. We will also collect administrative data from the factory to study any impact on firm- and worker-related outcomes.
