Monotonicity is not necessary for the Wald ratio to identify a Local Average Treatment Effect. Under random assignment … "less defiers than compliers" condition is substantially weaker than monotonicity. It has two implications which are … testable from the data, and it is closely related to those testable implications. Similarly, the local monotonicity condition …

Instrumental variables estimators typically must satisfy monotonicity conditions to be interpretable as capturing local … average treatment effects. Building on previous research that suggests monotonicity is unlikely to hold in the context of … impact on monotonicity bias of bandwidth selection in regression discontinuity (RD) designs, finding that "full sample …
