allows the effect of changing one of the binary independent variables to depend on the value of the other binary variable.
A: occurs when a selection process influences the availability of data and that process is related to the dependent variable.
B: is only important for finite sample results.
C: results in the OLS estimator being biased, although it is still consistent.
D: is more important for nonlinear least squares estimation than for OL
