This thesis contains three essays on how access to health care and health information affect health behaviors and health beliefs in developing countries. In the first chapter, I study why rural households in Bangladesh keep seeking health advice from untrained informal providers when mobile health services (MHS) are freely available from qualified public healthcare providers and how they can be nudged to adopt the MHS. Using a randomized controlled trial among 2900 rural households from 580 neighborhoods in Bangladesh, this paper studies whether and how the adoption of mobile health services can be improved. I find that information about the service improves households' awareness by more than 30 percentage points but does not affect the adoption in the following two months. Among the participants who were also encouraged to call at one of the MHS phone numbers to see how the service works, 63% attempted during the intervention and 22% of them used the service in the following two months. The adoption of MHS decreases households' health expenditure, mostly driven by the reduction in medicine consumption. This happened because households, who adopted MHS, also made fewer visits to informal providers who usually overprescribe medicine. The second chapter studies how information can affect people's health risk beliefs and health behaviors. The local prevalence of infections and the severity of its consequences are among the key determinants of the adoption of preventive behaviors for an infectious disease. By conducting a survey among more than 2000 adults in Bangladesh, I find that most people either do not know or underestimate the local prevalence of COVID-19 infections and overestimate its fatality rate. In a randomized experiment, I give the treatment group information about the coronavirus case number in their districts and the case fatality rate in Bangladesh and worldwide. Immediately after receiving the information, the treatment group perceives higher infection risk. Nine to fifteen days after the intervention, those who received information underestimate the local prevalence less and, consequently, still perceive higher infection risk than the control group. The treatment group also updates their belief about the fatality rate downward. Potentially due to this countervailing update of risk beliefs, the information does not have any effect on the self-reported preventive behaviors.In the final chapter, I develop a simple model which illustrates why opposition leaders can be very effective for the COVID-19 vaccination awareness campaign. To test this empirically, I also conduct an experiment in Bangladesh where 3,781 individuals in Bangladesh randomly received information about COVID-19 and its vaccines, the vaccination status of ruling and opposition leaders. While all treatments improved confidence on COVID-19 vaccines, the information about the opposition leaders' vaccination status decreased the perceived side effects. The participants from the opposition treatment are 11 percentage points more likely to intend to get vaccinated than the participants of the information treatment.
