Resources and Supply is Not Enough

More than 13 million needless deaths every year fromconditions for which safe, effective and affordable preventionand treatment exist

Insecticide treated nets prevent malariaCondoms to prevent HIV/AIDsWater purification to prevent waterborne illness

Families remain trapped in poverty, even when simpleyield-improving agricultural technologies and savingsinstruments are available.

Fast vs Slow Thinking

“Fast” Mammalian brain: involved more in decisions for now (whenwants are preferred) than for decisions for later.“Slow”Neocortex: involved in both types of decisions.

Cognitive Load

80 students brought into a laboratoryTold to memorize a number

50% memorize a 2-digit number (low cognitive load)50% memorize a 7-digit number (high cognitive load)

Given snack choice: fruit salad or chocolate cake

Shiv and Fedorikhin (1999)

Results (Ashraf et al, 2006)

Average increase in bank account savings: after 6 months,46%; after 12 months, 80%

Increase for those who took up: after 6 months, 192%; after12 months, 337%

Similar product subsequently used by the Bank to help clientskeep commitment to stop smoking

A word on methods: Field experiments

Need to know what works and why

But in evaluation, there is always the fundamental problem ofidentification

Randomized Control Trials (RCTs) allow for causal inferencethrough randomization into treatment and large sample sizes

Particularly helpful in demonstrating value of psychological &sociological factors in development

Incentives against Procrastination

Immunization rates of just5% in rural Udaipur(India)Small incentive (1 kg rawlentils per vaccine) raisedfull immunization to 39%

Children who wereoffered immunizationwithout lentil incentive:16%

Defaults and 401k Participation

Fortune 500 company401(k) started in 1985

Check box to contribute

In April-1998 key change

Check box not to contribute

Does opt-in vs. opt-out affect retirement savings?

Status Quo Effect vs. Company Tenure

It takes 20 years to overcome the cost of filling a form!

Page 35: Comprender la naturaleza humana

Just Assistance with Forms Makes Significant Difference in:

Access to Banking ServicesAmong people given a referral letter to a bank and instructions onhow to open an account, 90 percent had thought they would followthrough — but only 50 percent didA bank representative assisting people with the forms had a largepositive effect on take-up (Mullainathan and Shafir, 2009)

Applying to College:

Individuals receiving tax preparation assistance were also offeredhelp with the FAFSA & aid estimates compared against tuition costsCombined assistance & information increased FAFSA submissionsHigh school seniors whose parents received the treatment went from28%-36% more likely to have completed 2 years of college(Bettinger et al, 2012)

Social Identity

The drive for social inclusionis fundamental, sometimestrumping the drive forphysical sustenance.In his landmark studies,Harry Harlow showed thatinfant monkeys choose tostarve in the arms of a soft,cloth “mother” over havingaccess to milk from a wire“mother.”

Page 39: Comprender la naturaleza humana

Social Identity

Social Identity – Perception of oneness with a group of people – selfconcept extends to include social group.

Stems from:

Cognitive factors: categorization of individuals into groups;and salience of outgroupsMotivational factors: distinctiveness and/or prestige of thegroup; survival

Identifying barriers to adoption of new contraceptiontechnologies

Modern contraception provides unprecedented degree of choicefor women in developed countries, but adoption rates lag indeveloping world

Unmet need estimated at 25% in sub-Saharan Africa

Open question: What is driving the rates of excess fertility?

Assumed to be lack of “access” (availability, suitability,misinformation)

Results

Women given voucher alone:23% more likely to visit a family planning nurse38% more likely to take up a concealable form of contraception57% reduction in unwanted births

...than when they were given the voucher with their husband.

Only when women have greated autonomy to adopt contraceptiondoes it lead to a decrease in unwanted births.

...but is that the whole story?

Threats to the Social Identity

Proinflammatory cytokine activity and cortisol (i.e., stress) andthat these changes occur in concert with shame.

Chronic social self threats and persistent experience ofshame-related cognitive and affective states predictdisease-relevant immunological and health outcomes in HIV.

Neurologically, Social Exclusion = Physical Pain

(Eisengerger, Liberman, & Williams, 2003, Science)

(A) Increased activity in anterior cingulate cortex during exclusionrelative to inclusion. (B) Increased activity in right ventral prefrontalcortex during exclusion relative to inclusion. Both areas are active duringphysical pain.

Prosocial Motivations

In repeated economic experiments, people show a propensityto give up money in order to meet other needs.

Harnessing innovative distribution mechanisms

Female condoms: new technology that can prevent HIV/AIDStransmission and increase women’s contraceptive options – but adifficult technology to learn, need innovative distribution method

Field experiment context

Page 65: Comprender la naturaleza humana

Ashraf, Bandiera and Jack: “No Margin, No Mission? A Field Experiment on

Incentives for Public Service Delivery.” May 2013.

Design and implement a field experiment with SFH Zambia, apublic health organization

1. Census: Survey all salons in Lusaka (~2500)

2. Randomly assign 1200 salons to four treatments

3. Invite to training, learn about incentives

4. Sales and monitoring: collect monthly data on hairdressers forone year.

Alternative rewards

Tie reward (stars) to sales effort (# of stars proportional to social value)

Page 69: Comprender la naturaleza humana

Results

Stars (non-financial rewards) are much more effective thanfinancial incentives in this setting

Seems to be driven by warm glow effect and social comparison

Community Health Workers

Shortages of health workers across sub-Saharan Africaundermine national health systems

3% of health work force in Africa, which has 11% of world’spopulation and 24% of disease burden

In Zambia, 12 million people but only 646 doctorsCHWs a potentially innovative solution to this problemWhat are the optimal recruitment and compensation strategies
