This folder contains links to the data and programs used to generate Tables 1.5
and 1.6 in Mastering Metrics. Table 1.5 presents estimates of the
effects of winning the Oregon Health Plan (OHP) lottery on insurance
coverage and health care utilization. Table 1.6 presents estimates of
the effects of winning the OHP lottery on health indicators and
financial health. Data and programs are available at The Oregon Health Insurance Experiment website (http://www.nber.org/oregon/4.data.html). In order to access the data and code, you will need to use an NBER login. If you do not have one, you can create an account for free at https://www.nber.org/login/.

Code: 
Main programs:
* oregon_hie_qje_replication.do
	- This program replicates Tables III, V, and IX of the QJE paper. Table IV cannot be replicated because the required data is not publicly available. 
* oregon_hie_nejm_replication.do
	- This program replicates Tables S1, S2, and S3 from the NEJM paper.
* oregonhie_science_replication.do
	- This program replicates Table S7 and parts of Table S2 from the Science paper. Other parts of Table S2 cannot be replicated because the required data is not publicly available.

Additional programs are contained in folders named Programs_QJE, Programs_NEJM, and Programs_Science. These programs are called by the main programs above.
