Using administrative data: the question
• Administrative data: main objective is monitoring for decision making– can trace and describe trends of key inputs and outcomes of interest
• Question: how can it be used for impact evaluations?
• Complementary to survey data collection
• For either type of data sources, a pre-requisite for embarking in an impact evaluation is to have a clear identification strategy
• Call for expanding access to administrative data prominent US economists
![Page 3: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/3.jpg)
Using administrative data for impact evaluations: the potential
• Size: Universe of the target population
• Best placed to assess programs targeted to very specific groups – to be oversampled in surveys (the extreme poor, migrants), or geographic areas
• By-product of the existing monitoring of the social policy: cost
• time: characterize dynamics of impact
• Flexibility: can potentially look at different target groups, assess new variants
![Page 4: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/4.jpg)
Using administrative data for impact evaluations: the cons
• Data up-to-date? Differential capacity of municipalities or agencies in data collection
• Representativeness? ex.registries of the poor (as CadUnico) covers the entire target population?
• Data quality? Income (imputations), scope for over/under reporting (ex. Colombia PMT)
• Scope: limited set of variables. May be missing key outcomes or determinants of pathway of impact(ex. noncognitive skills, mental health, parenting practices)

Using administrative data for impact evaluation: the experience of Chile Solidario
• Non-experimental evaluation: method of regression discontinuity design
• Planned after the program had started
• Exploited the clear assignment :
• Eligibility based on proxy means score (CAS). Official cutoff by municipality
• Households invited from the bottom up of the CAS distribution in each municipality
• Program gradually rolled out, 4 cohorts 2002-2005, became law in 2004
![Page 6: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/6.jpg)
Chile Solidario: objectives and approach
1. Social inclusion
• Targeting the extreme poor (and vulnerable): bottom 5% CAS. From explicit demand for services to identification and invitation
• Central role of psychosocial wellbeing in social policy: 2 years of psychosocial support, local social worker
![Page 7: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/7.jpg)
Chile Solidario: objectives and approach
2. Social protection
• Short term cash transfer + guaranteed monetary transfers
• Preferential access for social services (demand)
• Making the supply side available (supply) and tailored to the needs of the poorest
• Beyond access to health and education: multiple dimensions and ‘minimum conditions’
![Page 8: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/8.jpg)
Chile Solidario: objectives and approach
3. Promotion
•.Identification of key skills and endowments to sustain exit from poverty (demand)
• Human capital of young and current generation
• Psychosocial capital
• Making supply side available (supply) and tailored to the needs of the poorest
![Page 9: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/9.jpg)
Data: Panel Survey Chile Solidario• CASEN 2003: identify a representative sample of ChS
participants and an observationally ‘comparable’ sample of non-participants • Rich set of outcomes (health, education, housing, income,
poverty/indigence) CASEN + added new modules: intergenerational mobility, psychosocial dimension (since 2006)• Representativeness? cohorts 2002-2003
• Mistake sampling scheme in 2004 sampled better off non-participants
• Followed sample 2004, 2006, 2007
• No baseline data
![Page 10: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/10.jpg)
Data: administrative data
• Panel of the administrative registry: Ficha CAS
• Demographics, housing/durables, employment, income, monetary subsidies
• In 2007 FPS : expanded into attendance to preschool, school, health visits, more detailed employment module,
• Detailed geographical information: 13 regions, 346 municipalities, 7000 neighborhoods.
• Can distinguish families vs households
• Coverage: 1/3 in 2000/1, to 2/3 after 2007
• Ficha vigente – updated every 2 years. Substantial churning families in/out
![Page 11: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/11.jpg)
The key role of the national ID
• Registro Unico Tributario RUT. use it to merge it to a large set of complementary data (SIIS presentation yesterday)
• Merged registry with:
• Administrative data from the program (identity participants)
• administrative data on social workers, caseloads (quality of implementation)
• participation on training/employment programs (unit level records available at the time of the evaluation)
![Page 12: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/12.jpg)
Descriptives: target of the bottom 5% in each municipality led to under-coverage nationwide
Proportion of participant among eligible households:
Cumulative entry around 50-60% of the potential target population
![Page 13: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/13.jpg)
Descriptives: social exclusion was higher among the poorest
Note: Only families eligible for SUF are considered (heads 20-50 years old).

regression discontinuity design: ‘effective’ cutoffs
• Exploit gradual roll out of the program over time to estimate effective thresholds that vary by municipality, over time
• inference caveat: window CAS within municipality, larger support nationwide
![Page 15: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/15.jpg)
Participation to the program by cohorts• Eligibility defined by the ‘effective’ cutoff

Main results: employment 2 years
![Page 18: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/18.jpg)
Going beyond average impacts to understand mechanisms
• Program is tailored to the needs: it is important to account for the initial conditions of beneficiaries
• compare households who had vs had not satisfied outcomes before 2002)
• Program evolved over time (supply side):
• compare cohorts before/after 2004
• In theory with current Ficha Social+ expanded historical information on programs could look at 6-10 years impact
![Page 19: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/19.jpg)
Supply side articulation: employmentPreferential access to:
• Self-employment programs (AAE)
• Employability (PNCL)
Exclusive access to:
• Job placement (wage subsidy SENCE, PROFOCAP)
• Self-employment programs (PAME)
• employability (habilitacion sociolaboral SENCE, competencia laboral mujeres PRODEMU, apoyo jovenes SENCE)
• Share programs exclusive to CS increased over time
• Lion share of programs for self-employment (75%)
![Page 20: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/20.jpg)
Results by initial conditions: take-up• Impact driven mainly by those who were previously
disconnected from social services (SUF)
![Page 21: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/21.jpg)
Results by initial conditions: take-up• Take-up Employment programs driven by those
inactive/unemployed before CHS
![Page 22: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/22.jpg)
Final employment outcomes show the importance of the supply side
• Spouse: activation employment by 20% only for those cohorts exposed to the supply side expansion
![Page 23: The use of administrative data for program evaluation Rio](https://reader033.fdocuments.in/reader033/viewer/2022052909/5598aa851a28abca3f8b45df/html5/thumbnails/23.jpg)
To summarize• Social protection: activation of the demand for a large array of
social programs
• Important demand side constraints (information, transaction costs, psychic costs activation)
• Impact persists over time
• Social inclusion: activation demand for programs for those who were previously disconnected
• Take-up of monetary transfers
• Take-up of labor market programs
• Promotion: No. Activation demand does not translate into final outcomes if not met by supply side:
• Need comprehensive activation component: technical and soft skills training, internship, job intermediation and placement

Conclusions• Social registries starting data source for impact evaluation:
move beyond monitoring
• Cross check with unit record data on access to services, use of services)
• Can go to fine level of disaggregation, exploit time dimension
• Might be missing key outcomes (income, psychosocial dimensions)
• Caveat representativeness, quality
• Even programs are already at scale, refine questions of impact: quality of implementation, complementarity of services to target groups, experimentation
