Program evaluation
The field of study concerned with estimating the effect of a program, policy, or some other intervention or treatment. (From web) Program evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, particularly about their effectiveness and efficiency. TERM 2
Causal effect
DEFINITION 2 The expected effect of a given intervention or treatment as measured in an ideal randomized controlled experiment. TERM 3
Treatment effect
DEFINITION 3 The causal effect in an experiment or a quasi-experiment; see causal effect. TERM 4
Differences estimator
DEFINITION 4 An estimator of the causal effect constructed as the difference in the sample average outcomes between the treatment and control groups. TERM 5
Partial compliance
DEFINITION 5 Occurs when some participants fail to follow the treatment protocol in a randomized experiment.
Attrition
The loss of subjects from a study after assignment to the treatment or control group. TERM 7
Hawthorne effect
DEFINITION 7 See experimental effect(From web) The central idea behind the Hawthorne effect, a term used as early as 1950 by Elton Mayo and Fritz Roethlisberger, is that changes in participants' behavior during the course of a study may be "related only to the special social situation and social treatment they received." TERM 8
Differences estimator with additional
regressors
DEFINITION 8 Yi = b0 + b1Xi + b2W1i + + br+1Wri + ui TERM 9
conditional mean independence
DEFINITION 9 The conditional expectation of the regression error ui, given the regressors, depends on some but not all of the regressors. TERM 10
Differences-in-differences estimator
DEFINITION 10 The average change in Y for those in the treatment group, minus the average change in Y for those in the control group.
