# _Sri Lankan Longitudinal Survey of Enterprises (SLLSE)_

The Sri Lankan Longitudinal Survey of Enterprises (SLLSE) is a long-term panel survey of microenterprises designed to assess the impact of a wage subsidy, plus a savings and a business training intervention as supplementary interventions (see de Mel et al, 2010, 2016 for details on the study and survey design). The baseline survey was intended to be a representative survey of urban microenterprises with two or fewer paid employees, owned by males aged 20 to 45, and operating in non-agricultural sectors, in the Colombo, Kandy, and Galle-Matara areas of Sri Lanka. It was conducted between April and October 2008. The first phase occurred in April 2008 as part of a larger panel survey and also included other urban areas in Sri Lanka. In October 2008, a booster listing exercise and survey took place in order to attain a larger sample for the intervention. The original sample was also re-interviewed during the October 2008 survey, resulting in a total sample of 1,533 firms. These firms were then randomly allocated into treatment and control groups, the latter of which consisted of 286 enterprises. After these two survey rounds, the sample was re-interviewed in 10 additional follow-up rounds, consisting of six-monthly surveys every April and October from 2009 through 2012, and two additional surveys in April 2013 and April 2014.

We included firms allocated to the control group that were either part of the booster sample, or surveyed in April 2008 and reported no change in the line of business in October 2008, taking the survey conducted in October 2008 as the baseline. Our baseline sample then comprises 284 firms, which we follow for a total of eleven rounds (baseline plus ten follow-ups).

We coded _survival_ from round to round to one, if:

- the respondent reported that he was still working in the same line of business as in the previous round; or

- the business was now being operated by another household member; or

- the respondent had sold the business to someone else to run.

- Otherwise, _survival_ was coded to zero.

Starting in round 6, we additionally used information from the attrition section to code _survival_ , coding it to one if the respondent could not be located or refused to participate in the survey, and the proxy respondent said that the owner was either still operating the business, or the business was being run by another family member or by someone else. If the proxy respondent said that the business had closed down, we coded _survival_ to zero.

_Newfirmstart_ was coded to one, if the respondent was operating a different business, after closing, changing or selling the business, and to zero otherwise.

In a final step, we recoded _survival_ for rounds 3 to 11, so that it reflected survival since baseline, by recoding it to zero for all subsequent rounds if it had been coded as zero in a given round and a new firm start had been coded in the same round or later.

# _Lomé Informal Enterprise Survey (TGINFORMALITY)_

The Lomé Informal Enterprise Survey (TGINFORMALITY) was used for an impact evaluation of two training interventions for informal businesses in Lomé. The sample was drawn from applicants to the government project under which these trainings were conducted and consists of 1,500 microenterprises. Applicants had to be in business for at least 12 months, have fewer than 50 employees, operate outside of agriculture, and not be a formally registered company. Further details on the intervention, sample selection and survey can be found in Campos et al. (2017). The baseline survey was conducted between October 2013 and January 2014. Firms were then randomly assigned into one of two treatment groups and one control group, each of 56
