Allowing measurement errors widens the bounds on the ATE substantially as can be seen in figures 3 and 4 for a true participation rate of 50% and 70% respectively. The MIV and MTR assumptions still hold substantive identifying power. Even more identifying power lies now in assuming that there are no false positives - especially for a true participation rate of 50%. Assuming this leaves the bounds only slightly larger than the ones without measurement error. Assuming no false positives is less powerful when the true and reported participation rate are further apart.
