I am a Postdoctoral Health Economics Fellow at Stanford University (S-SPIRE).
My areas of research interest include Health Economics, Applied Econometrics, Labor Economics, and Economic Demography. My work aims to understand and analyze the factors relevant to consumers' decisions on healthcare consumption. I am also interested in how health insurance reforms affect both the supply and demand side of healthcare markets.
Working Papers:
1) Reference Pricing - The Case of Screening Colonoscopies
Abstract:
In this analysis, we study the introduction of reference pricing to the California Public Employees' Retirement System. Reference pricing changes the relative price of using a hospital versus an ambulatory surgery center (ASC) for patients receiving a colonoscopy, leading to as good as random variation in patients’ use of ASCs. We find a 10 percentage point increase in the share of patients using an ASC, leading to a $2300 to $1700 reduction in total spending for patients who switch to ASCs. Our results suggest that the use of ASCs has a causal effect on spending and no negative effect on patient health outcomes.
2) Understanding the Distributional Impacts of Health Insurance Reforms: Evidence from a Consumer-Cost Sharing Program
Abstract:
We examine the heterogeneous effects of a health insurance reform on the distribution of spending for the California Public Employees' Retirement System (CalPERS). The reform changes the relative prices faced by CalPERS members between higher-priced and lower-priced healthcare providers. Using medical claims data for CalPERS and an unaffected control group, we estimate the quantile treatment effects of the program. We find large, negative effects at higher quantiles of the spending distribution, with smaller effects at lower quantiles, suggesting a relative right-tail reduction. These effects are not captured by mean estimates but have important policy implications.
