| Field Abstract | Before Reducing racial disparities in health outcomes is a major policy concern in the United States. Although there has been recent progress to close the gap, black men continue to experience earlier morbidity and mortality from preventable and manageable medical conditions, and live on average 3.5 years less than their white male peers. An oft-prescribed solution to close this stubborn gap is to increase the diversity of the healthcare workforce. Another common policy tool to increase take-up of preventative healthcare services is conditional cash transfers (CCTs). In this randomized evaluation, we will estimate the effects of CCTs and a racially concordant physician on the uptake of preventive health services in Oakland, California. | After Reducing racial disparities in health outcomes is a major policy concern in the United States. Although there has been recent progress to close the gap, black men continue to experience earlier morbidity and mortality from preventable and manageable medical conditions, and live on average 4.2 years less than their white male peers. An oft-prescribed solution to close this stubborn gap is to increase the diversity of the healthcare workforce. Another common policy tool to increase take-up of preventative healthcare services is financial incentives. In this randomized evaluation, we will estimate the effects of financial incentives and a racially concordant physician on the uptake of preventive health services in Oakland, California. |

| Field Primary Outcomes (End Points) | Before The primary outcome is the number of preventative care services selected by the participants at our free clinic. Whether subjects elect to receive a flu shot. | After The primary outcome is the number of preventative care services selected by the participants at our free clinic. |
| Field Primary Outcomes (Explanation) | Before | After The preventative services vary from non-invasive to more-invasive - (body mass index, blood pressure, cholesterol screen via fingerprick, diabetes screen via fingerprick and flu shot). |
| Field Experimental Design (Public) | Before We plan to randomly assign doctors to participants and offer a list of preventative care treatments that the participant can avail from the assigned doctor. We will also ask the participant about his medical history and his perceptions/attitudes towards healthcare. The participants will be adult African American males. The primary recruitment site will be barbershops. In addition to barbershops, we will also recruit at flea markets in Oakland and Berkeley. Participants will be told about the study and requested to fill in a baseline survey in exchange for a $25 cash voucher that can be redeemed at the barbershop itself. Participants at flea markets will be offered a $10 bill instead of vouchers. We will request the participants to then visit a study clinic, which we will set up in Oakland, in exchange for $50. Participants will also be offered a free Uber ride to the clinic. At the clinic, the participants will randomly be assigned one of the doctors present. Before they meet the doctor, they will need to fill out a tablet-based clinic survey. The tablet will randomly assign one of three vouchers, of value $0, $5, $10, to the participants for flu shots. The participants will then select the preventative care they want to receive from the doctor. | After The experimental design was as follows: (1) Recruitment: Adult men who self-identified as African American were recruited at community sites in the Oakland, CA area. Most recruitment sites were black-owned barber shops, though some men were recruited from flea markets, churches and schools. Those who chose to enroll in the study completed a baseline survey regarding demographics, health status, history of health care utilization and trust. Survey completion was incentivized by haircut vouchers at the barbershops or $10–$20 in cash, depending on the venue. The participants received coupons for free cardiovascular health screenings to redeem at a clinic that was run on Saturdays specifically for the purposes of the study. It was emphasized that the doctors would not be able to address other health concerns. Uber donated ride-sharing services to transport individuals to and from the clinic. (2) Presentation and ex-ante demand: Subjects who presented at the clinic were randomized to a male study doctor and an incentive amount. After check-in, the subject was placed in a private patient room. At that point, the subject was given an unconditional cash payment for presentation at the clinic ($50). Afterwards, the subject was introduced to their assigned doctor through a tablet device, which included a generic description of the doctor’s background and his actual photo. Subjects were then asked to select which of five preventative health care services they would like to receive from their assigned doctor. One of the services — a flu shot — was a surprise service the subjects learned about on presentation, at which point they were randomly offered a financial incentive ($0, $5, $10) conditional on selecting to receive the vaccination. (3) Ex-post demand: After selecting the desired services, the assigned doctor met with the subject. Study doctors were provided with a list of each subject’s ex-ante demand; however, they were instructed to encourage participants to obtain all of the services. The doctors were informed that, due to restrictions on the malpractice coverage purchased for the study, they were not able to provide services outside those in the screening. The ex-post demand (the demand after interacting with the assigned doctor) was also recorded. Subjects were asked to fill out a satisfaction survey after the encounter. |
