Abstract
This paper describes the analysis plan for a randomized controlled trial evaluating Twitter as a medium for financial literacy advice and marketing among second-hand clothes sellers in a market in Nairobi, Kenya. We also assess the effect of sales targets in the same population. In 2014 we randomly selected stallholders to be part of four different treatment groups that either received financial literacy advice through Twitter, financial literacy and marketing advice through Twitter, or two different types of sales targeting approaches. This study aims to identify the impact of these interventions on business practices and overall business performance. This plan outlines our evaluation questions, outcomes of interest, and a proposed econometric approach.

Experimental Design
Experimental Design
This study aims to test the impact of Twitter as a medium for financial literacy advice and marketing, as well the effects of sales targeting exercises in improving business outcomes among market vendors with an experimental design involving four different treatment arms: two related to the use of Twitter in providing business services and two related to the use of sales targets.
For the Twitter-based treatments the project developed two Twitter-baed busi- ness services, which gave small enterprises business advice and a medium for mar- keting through the Twitter platform. To our knowledge there have not been any studies assessing the use of Twitter in financial training and business development. The project aims to provide insight on this front while contributing to evidence regarding the role of financial literacy in affecting business performance for SMEs.
The project also tested two sales target based interventions. The use of sales targets is a well-known tool used among businesses to track sales performance and provide motivation to drive sales, yet our qualitative work demonstrated that the vendors in our target population, in the main, do not engage in such practices. We engaged selected vendors in the study in a sales targeting exercise, which for some was also supplemented by a paper tracker to help track sales progress visually.
Experimental Design Details
Randomization Method
The project used a randomized evaluation strategy. We conducted a census of Adam’s market to gather information on the business type of stalls within the market, as well as the contact details of stall managers or owners. A total of 479 vendors were surveyed in the census. Only stalls that sold Mitumba were considered as eligible to participate in the study and therefore surveyed for the census. We then randomly selected 70 subjects for each of the four treatment groups, and the same number for the control group.
