Community Based-Conditional Cash Transfer Program Overview A pilot CCT program implemented in 40 villages of three

districts. 5,000 households and 13,000 beneficiaries Conditionalities:

Education: Primary school enrollment and 80% attendance for children 7-15

Health and nutrition: Regular check ups for children younger than 7 (three times a year) and for elderly (once a year)

Selection of beneficiaries: Community targeting and proxy means test

Benefits: US$3 per month per child US$6 per month per elderly Maximum benefit per month: $18

Bi monthly payments since January 2010. Ten payment cycles

Institutional arrangements Community-based managed by a Social Fund

Central. Overall management and monitoring, support to subnational authorities, disbursement of funds.

District. Technical support and guidance including training and follow-up of implementation in the villages.

Community level. Selection of beneficiaries, day to day implementation, collection of information to register beneficiaries and to verify compliance with conditions, direct payments

Program overview – survey results

Median household has received 8 payments

received TZS 22,500 (US$13) last payment

Delivery 94% pick up from village office

3% CMC member delivers at home

At mid-line, asked people about conditionalities 15% mentioned all 3 conditions

27% mentioned 2 conditions

51% mentioned 1 condition (To be fair, not all conditions apply to each household.)

Impact evaluation – Key questions What is the impact of CCTs on various outcomes for vulnerable

children and the elderly? Conditionalities

Education Health

Cash transfers Consumption Savings Transfers within community

Community administration Trust in community

Underlying question: Is the community-based model as effective at

achieving health, education, and consumption gains as has been the case of more centrally administered models used elsewhere?

Page 8: David Evans Katrina Kosec Joachim De Weerdt World Bank ... · Health and nutrition: Regular check ups for children younger than 7 ... Project will be rolled out in control villages

Impact evaluation model Randomized-control trial

Among 80 villages with long history of TASAF assistance

Household selection process conducted in all 80 villages

Randomly select 40 to enter the program

Other 40 serve as control

Project will be rolled out in control villages after 2012 end line survey.

Evaluation Strategy Treatment and comparison communities are roughly

balanced

If anything, treatment communities are slightly worse off – highlights importance of baseline

Differences-in-differences

Treatment & Control, Before & After

Specification

(Treatment dummy is collinear with households fixed effects and so is dropped.)

Impact of interest is β3

Caveat: Baseline survey was carried out before final selection of households, so that 9% of households in treatment villages ultimately not treated

Two specifications Intent-to-Treat: Treatment = Assignment to Treatment

Village

What is the impact of being initially assigned to treatment (whether you received it or not)?

Treatment on the Treated: Treatment = Self-reported Treatment, using Assignment to Treatment Village as Instrumental Variable

What is the impact of actually receiving treatment?

(If we didn’t use the instrument, this would be biased. The instrument is randomized and solves this problem.)

Depending on variable, first stage is between 0.9 and 0.95

Being assigned to treatment increases your odds of treatment by 90 to 95%: great instrument

Annual Expenditures (in TSH)

Significant increase in non-food expenditures, particularly for children’s clothing and women’s clothing (surprising).

Also tested for health service expenditures and expenditures on ceremonies: No significant impact.

Summary of results Strong impacts

Health-seeking behavior Expenditures (especially children’s)

Trust Increase in trust of leaders: Seen in action Decrease in trust on people in general: Friction over

targeting?

Limited impacts in other areas Fewer sick days for children Early enrollment to school (but not enrollment or attendance

for 6-17 year olds) Increase in non-bank savings (from 1% of households to 3% of

households)

Discussion of impact results Dissolution of impacts

Households in treatment villages received 8,313 TZS (US$4.90) less in private transfers over last 12 months

6% reduction in benefits

Education condition

High baseline levels of enrollment

Not binding in most cases

How well did the program actually function?

Dropped

Other

Page 24: David Evans Katrina Kosec Joachim De Weerdt World Bank ... · Health and nutrition: Regular check ups for children younger than 7 ... Project will be rolled out in control villages

Irregularities 2% reported having been asked for a contribution

Contribution = 9% of transfer

7% reported receiving less than usual at the last payment but were unable to explain why

Some complains of dishonest staff in quantitative survey

Issues to look into, but relatively small proportion of program

Page 25: David Evans Katrina Kosec Joachim De Weerdt World Bank ... · Health and nutrition: Regular check ups for children younger than 7 ... Project will be rolled out in control villages

Focus Group Findings Range of groups (in 6 TV)

Health & education providers, village councils, beneficiaries, non-beneficiaries

Findings Beneficiaries: Program is great, but more money

General openness to conditionalities: Some complaints on the need for elderly health visits [but note big improvements in elderly clinic visits]

Non-Beneficiaries: Insufficient transparency in selection process

Overall positive – highly participatory

Some cases of people with means included or truly needy excluded

No suggestion of reduced traditional solidarity systems

Page 26: David Evans Katrina Kosec Joachim De Weerdt World Bank ... · Health and nutrition: Regular check ups for children younger than 7 ... Project will be rolled out in control villages

Policy Implications: the way forward

Government decision to scale up the CCT as part of a safety net (0.2% of the GDP per year)

First phase: 250,000 households nationwide

Combined with a cash-for-work to same households to smooth consumption in lean seasons

Required institutional adjustments at central and subnational levels

Strengthen implementation arrangements and adjust design parameters:

Eligible groups, conditions, benefit structure, targeting system and process, decentralized operation, information systems
