“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

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%

Status Quo Effect vs. Company Tenure
It takes 20 years to overcome the cost of filling a form!
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.”
.
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.
And. . .
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.

Field experiment context
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)
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
