Summary, Etc.  

요약This thesis uses a broad toolbox of empirical econometric methods to study various important questions in health economics and economics of education such as patient provider relationships, vaccine hesitancy and teacher certification requirements. The goal of my thesis is to help policy makers design more informed and sound policies that ultimately improve the health outcomes of patients and academic outcomes of students.In Chapter 1, I study the impacts of a mental health provider's exit on a patient's care utilization and related health outcomes by using Colorado All Payer Claims Database. I estimate that patients on average are 40% less likely to have a monthly mental health visit following a provider's exit. Moreover, this reduction in care utilization is much more pronounced among patients whose providers exit before March 2020 (52%) as opposed to those after March 2020 (24%). The smaller negative effect for post-COVID provider exits could be partly explained by the rapid adoption and expansion of telemedicine which has greatly improved accessibility of care, especially in the more severe provider shortage areas. I also find evidence to suggest that provider exits before COVID result in increased likelihood of emergency room visits among patients in the short run, but not after COVID. These results together suggest that policy makers and insurers need to work together in supporting the use of virtual care to maintain patient access and practice capacity for mental health care delivery.In Chapter 2, together with Brad Larsen, Adam Kapor, and Chuan Yu, I study how increased licensing stringency affects the quality distribution of public school teachers. We offer a theoretical model justifying both reactions. Using data from 1991--2007 on licensing requirements and teacher characteristics, we find that stricter licensing requirements, especially those emphasizing academic coursework, increased the left tail of the distribution of college selectivity among secondary school teachers. We find no evidence of disparate effects for high-minority or high-poverty school districts.In Chapter 3, together with Alexei Dunaway, Kateryna Pitsunova, Nandita Hore, Radwa Hamed, I study what behavioral nudges and media formats could encourage the sharing of true information about COVID and reduce vaccine hesitancy in South Africa. We examined eight different interventions across a participant group of over 3,000 survey respondents on Facebook. We found that focusing on relatable content can increase the probability of sharing vaccine-related messaging by 6.9 p.p. and motion graphics are more effective relative to still images. None of the behavioral nudges is effective in increasing the probability of vaccine take-up; however, motion graphics and videos are effective in increasing the probability of vaccination by 6.3 and 5.8 p.p. respectively compared to still images. We also found huge geographic variation across various treatments, suggesting the importance of micro-targeting based on the geographical locations of social media users.
