Well over two dozen different terms for identification appear in the econometrics literature, including set identification, causal identification, local identification, generic identification, weak identification, identification at infinity, and many more. This survey: 1. provides a general framework for characterizing identification concepts, 2. summarizes and compares the zooful of different terms for identification that appear in the literature, and 3. discusses concepts closely related to identification, such as observational equivalence, normalizations, and the differences in identification between structural models and randomization based reduced form (causal) models.
