Q

randomized trial

A

The ideal type of experiment designed to test causality, whereby a group of individuals is randomly divided into a treatment group, which receives the treatment of interest, and a control group, which does not.

Q

bias

A

Any source of difference between treatment and control groups that is correlated with the treatment but is not due to the treatment.

Q

attrition

A

Reduction in the size of samples over time, which, if not random, can lead to bias estimates

Q

control variables

A

Variables that are included in cross-sectional regression models to account for differences between treatment and control groups that can lead to bias.

Q

quasi-experiments

A

Changes in the economic environment that create nearly identical treatment and control groups for studying the effect of that environmental change, allowing public finance economists to take advantage of randomization created by external forces

16
Q

difference-in-difference estimator

A

The difference between the changes in outcomes for the treatment group that experiences an intervention and the control group that does not.

17
Q

structural estimates

A

Estimates of the features that drive individual decisions, such as income and substitution effects or utility parameters.

18
Q

reduced form estimates

A

Measures of the total impact of an independent variable on a dependent variable, without decomposing the source of that behavior response in terms of underlying utility functions.
