Abstract
Measuring informal work is crucial for policy making, especially in development countries where informal work represents a high share of employment. Moreover, existing evidence shows that reporting engagement in work-related activities may differ across population groups. For the case of El Salvador, official data shows that women that answer by themselves register a lower participation rate than when data is reported by another household member. This behavior could be endogenous, since women are more likely to be at home so they perceive that they are not working, but it can also be that they are more likely to underreport.

The objective of this project is threefold. First, it aims to advance our understanding of how to obtain improved measures of labor, especially of those activities that tend to be underestimated in households’ surveys, such as informal and sporadic activities. More specifically, this project will provide experimental evidence on how to improve data collection on informal work, focusing on women and youth in non-urban (rural and peri-urban) areas. Second, it will also explore if the type of respondent (self or proxy) affects how labor participation is measured. Finally, this project aims to provide evidence on women’s and youths’ preferences on formal work attributes.

To achieve the first two goals, the plan is to design and implement a survey experiment to measure and compare the impact of different methods of collecting information on informal work and of the type of informant. The evidence on women's and youths' preferences for formal work attributes will be obtained from a discrete choice experiment inspired in Datta (2019).

Interventions

Intervention(s)
This project aims to advance our understanding of how to obtain improved measures of labor, especially of those activities that are usually miscounted in household surveys such as causal and sporadic activities.

There are two interventions in this trial:
• Members of the households assigned to treatment group 1 will be exposed to an additional survey module (Activities Module) before collecting their labor information. The Activities Module includes a list of the most common labor activities that people in their region do. The list is curated to use to provide examples of different income-generating activities that can be considered as work for statistical purposes.
• Members of the households assigned to treatment group 2 should provide their labor information by themselves (as opposed to using a proxy respondent as is common in household surveys).

Moreover, all households will respond to a discrete choice experiment that aims to measure respondents' willingness to pay on different attributes related to formal employment.

Experimental Design

Experimental Design
Group status: Control group
Type of labor module: Standard (LSMS labor module following 19th, ICLS)
Type of respondent: Main household respondent or if another household member (15-64 years old) is present, he/she provides his/her own information.

Group status: Treatment group 1
Type of labor module: New labor module that includes a new list of work activities
Type of respondent: Main household informant or if another household member (15-64 years old) is present, he/she provides his/her own information

Group status: Treatment group 2
Type of labor module: Standard (LSMS labor module following 19th, ICLS)
Type of respondent: Only self-respondents, selected household members (15-64 years old) must provide their own information

Randomization Method
Computer randomization for selection into experiment arms: C, T1, or T2.
Randomization Unit
Unit of randomization will be the household.
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
1008 households
Sample size: planned number of observations
3,024 individuals
Sample size (or number of clusters) by treatment arms
336 households C, 336 households T1, 336 households T2
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
For the statistical power and sample size estimations, we assume that, for the T1 and T2 comparison, we will have information on 672 households (a total of 336 households in T1 and T2). Further conservative assumptions are the following: an intra-household correlation (ICC) of 0.12, a type I error rate of 0.05, and statistical power of 0.9. Considering this, the minimum detectable effect (MDE) for the labor participation outcome will be 8.8 percentage points.
