Primary Outcomes (End Points)
|
Before
We will test the following 10 core hypotheses:
1. The interventions boost expenditure and savings compared to the control group.
2. The lump-sum intervention boosts expenditure the most in the short run, the monthly intervention boosts expenditure the most in the medium and long run.
3. The interventions increase the probability of living in a large city.
4. Null: The interventions do not change job search. The interventions could decrease job search (through an income effect) or increase job search (through a liquidity effect).
5. Null: The interventions do not change self-employment rates.
6. Null: The interventions do not change wage-employment rates.
7. The interventions improve match quality (earnings, spell and expected future duration, match with skills, job satisfaction). The monthly payments will be more effective than the lump-sum treatment.
8. The interventions boost mental health. The monthly payments more so than the lump-sum payment. The effects would be larger for workers assigned to the monthly payments than the lump-sum payment.
9. The interventions boost female autonomy and friendship networks.
10. People are able to select into the scheme that benefits them the most financially (expenditure at endline) and in terms of their overall well-being (life satisfaction + mental health).
These core hypotheses will be tested using the data collected with the bi-monthly high frequency surveys. We will submit a separate PAP for the endline data collection.
Primary outcomes (end points)
We will study the above mentioned hypotheses by looking at treatment effects on the following families of outcomes.
1. Expenditure plans
2. Savings plans
3. Job-search plans
4. Expenditure outcomes
5. Savings outcomes
6. Job-search outcomes
7. Employment status
8. Employment quality
9. Migration outcomes
10. Reservation wages
11. Psychological welfare (mental health + life satisfaction)
12. Female empowerment and friendship networks
Estimation
We will focus on the following comparisons: (i) monthly payment vs control, (ii) lump-sum payment vs control, (iii) monthly payment vs. lump-sum payment. To estimate the overall effect of displacement insurance, we will also estimate pooled treatment effects across both treatment arms on primary outcome families 4. (expenditure), 6. (job-search), 7. (Employment status), 10. (Reservation wages) and 11. Psychological welfare.
The level of observation for the main specification will be at the month-individual or survey-individual level. When estimating treatment effects we will consider the following time periods in addition to estimating average effects across time:
1. Treatment effect in the first two months after the start of the payments to study the effect of the lump sum treatment against the monthly payment.
2. Treatment effect in the month three to six after the start of the payments to study the effect of the lump sum treatment against the monthly payment.
3. Treatment effect after the end of the pay-out period of monthly payments (month seven to ten) to study the persistence of treatment effects.
We will also estimate more disaggregated treatment effects over time where applicable.
We will estimate treatment effects using an ANCOVA specification with further control variables. We will select control variables using LASSO algorithms for each outcome separately.
To limit concerns related to multiple hypotheses testing when there are multiple outcomes, we will construct an index for all primary outcome families in addition to estimating impacts on the individual outcomes.
We also plan to leverage the exogenous variation created by the experiment to estimate a structural model of consumption and job search decisions.
Heterogeneity
We will explore treatment effect heterogeneity with respect to the following primary dimensions: (i) policy preferences: a dummy for preferring the monthly payment scheme, (ii) above median baseline savings.
We will also explore heterogeneity along the following secondary dimensions: (iii) welfare at baseline: being above the median level of the psychological welfare index and (iv) empowerment at baseline: a dummy for having experienced an improvement in empowerment over the course of the previous employment spell. We will also investigate heterogeneity using endogenous stratification using leave-one-out estimators to split our sample into groups based on predicted job-search, expenditure and migration outcomes. We will also use causal forests to analyse further heterogeneity dimensions.

These core hypotheses will be tested using the data collected with the bi-monthly high frequency surveys. We will submit a separate PAP for the endline data collection. 14 months after treatment, we will run an in-person endline survey. We edited this registration to include the endline outcomes, without changing the pre-specification for high-frequency outcomes.
Primary outcomes (end points)
We will study the above mentioned hypotheses by looking at treatment effects on the following families of outcomes.
1. Expenditure plans
2. Savings plans
3. Job-search plans
4. Expenditure outcomes
5. Savings outcomes
6. Job-search outcomes
7. Employment status
8. Employment quality
9. Migration outcomes
10. Reservation wages
11. Psychological welfare (mental health + life satisfaction)
12. Female empowerment and friendship networks
Additional primary endpoints measured in the endline survey:
13. Incentivized willingness-to-pay for displacement insurance.
Based on analysis of the high-frequency data, we will focus our analysis on the following primary outcome families: (4) expenditure outcomes, (7) Employment status, and (9) migration outcomes. We will additionally focus on the analysis of informal transfers to and from others as we found this to be an important dimension of how workers react to the insurance payments in the high frequency surveys. We treat the other outcome families as secondary for the sake of the endline analysis.
Estimation
We will focus on the following comparisons: (i) monthly payment vs control, (ii) lump-sum payment vs control, (iii) monthly payment vs. lump-sum payment. To estimate the overall effect of displacement insurance, we will also estimate pooled treatment effects across both treatment arms on primary outcome families 4. (expenditure), 6. (job-search), 7. (Employment status), 10. (Reservation wages) and 11. Psychological welfare.
The level of observation for the main specification will be at the month-individual or survey-individual level. When estimating treatment effects we will consider the following time periods in addition to estimating average effects across time:
1. Treatment effect in the first two months after the start of the payments to study the effect of the lump sum treatment against the monthly payment.
2. Treatment effect in the months three to six after the start of the payments to study the effect of the lump sum treatment against the monthly payment.
3. Treatment effect after the end of the pay-out period of monthly payments (months seven to ten) to study the persistence of treatment effects.
4. We will also estimate the impact on endline measures where applicable.
We will also estimate more disaggregated treatment effects over time where applicable.
We will estimate treatment effects using an ANCOVA specification with further control variables. We will select control variables using LASSO algorithms for each outcome separately.
To limit concerns related to multiple hypotheses testing when there are multiple outcomes, we will construct an index for all primary outcome families in addition to estimating impacts on the individual outcomes.
We also plan to leverage the exogenous variation created by the experiment to estimate a structural model of consumption and job search decisions.
