Write a paper on payment gaps of uber drivers based on race

The project aims to identify whether race might influence the payment on transportation platforms (bolt/uber drivers). This might be influenced due to the rating system and amount of tipping by the passenger. A theoretical background is required and a model needs to be established. It must be defined which data and variables would be needed to test the relationship between race and payment gap. The data itself is not required! Only the methodology needs to be described.The intro needs to present a research gap and relevance of the topic. Discussion and conlcusion are required with possible limitations and future research outlooks. 8-10 pages max.
