An introduction to econometrics used in RCTs by Alberto Abadie can be found here.

A lecture series on field experiments by Dean Karlan and John list can be found here.

My recommendations are:

In Part 1:

• Failures in field experiments (01:35:00-01:54:00)

• New problems that arise with randomization (02:02:00-02:08:00)

In Part 2:

• List's 14 tips on running experiments (See also List, JEP 2011 )

In Part 3:

• First 30 minutes: Unit of randomization

• Randomization (00:30:00-01:16:00)

• Data collection issues (01:22:00-01:41:00)
