Where available attrition rate refers to the control group, otherwise attrition rate refers to the total sample.

- a. Only part of the full sample has a panel structure. Sample size, time frame, and attrition reported here refer only to the panel sample. One of the outcomes the authors assess is whether the respondent no longer has a business. The timeframe is indefinite and the outcome is measured as a binary variable equal to 1 if the respondent used to have a business but no longer has one.

- b. The authors use different samples in the analysis. S1 denotes sample 1 and S2 denotes sample 2. Sample sizes refer to the combined sample, which is the analysis sample.

- c. The intervention consisted of different methods to increase the salience of lost sales due to changeouts (running out of change). Firms were surveyed weekly and the experimental design relied on random variation in the introduction into the study. Hence the number of survey waves and length of follow up vary.

- d. There was an additional treatment arm, to which 304 study participants were assigned. We report only on the entrepreneurship program treatment arm and the control group.

- e. Data comes from two sources: (1) a one-year follow-up and (7) social security data, covering a horizon of up to 7 years. We do not consider the longer term horizon since the data is not able to assess survival. The death rate of the control group is provided in a footnote in the context of attrition.

- f. Sample sizes and attrition only refer to the panel sample.

- g. The authors study two groups of women: women who were already operating a business at baseline (current business owners) and women out of the labor force but interested in starting a business (potential business owners). Survival is only assessed for current business owners, and so we focus only on this sample here.

- h. Death rates are based on the pooled information from the two long-term follow-up surveys.

- i. The intervention randomly created social networks among firm owners.

- j. The business training was part of a larger business plan competition. Training was randomly assigned among enterprise owners who presented their project bevor the competition panel. We report only on the sample that presented before the panel.

- k. We calculated the death rate in the control group, based on information provided in the article.

- l. The authors note that no firm permanently exited the tailoring business during the course of the study, but that some closed their businesses temporarily for health or other reasons.

- m. Survival is measured as 1 if the individual was self-employed in 2011 and self-employed in 2013.
