mtemore is the old version of the command mtebinary. mtemore was designed to produce results from Kowalski (NBER 22363, 2016), and mtebinary was designed to produce results from Kowalski (NBER 24647, 2018). mtemore estimates the marginal treatment effect (MTE) function using a binary instrument and a binary endogenous variable. The MTE is defined as the difference between the potential treated outcome and the potential untreated outcome for an individual for whom the net benefit of treatment equals the cost of treatment, i.e., an individual marginal to selecting into treatment.
