Using these treatment effect estimates, I determine how well physicians matched patients to the appropriate drug. By looking at trends in matching over time, I look for evidence of physician learning. Additionally, using patient-specific treatment effects, I look at geographic variation in a number of measures to better understand variation in quality of care. Lastly, I build a theoretical model to study how the threat of waiving copayments affects the optimal insurance contract between the insurer and the patient and payment contract between the insurer and the provider. I find that the threat of waiving copayments may result in reduced patient welfare.application/pdfen-USCopyright is held by the individual authors.geographic variation; heterogeneity; incentives; person-centered treatment effects; physiciansEconomicseconomicsThesis
