A note on the use of logged variables in interaction terms: why units matter
Article Abstract:
Units of measurement for models with logged variables must be chosen with care to avoid presenting misleading information. For loglinear models the coefficient of the logged variable hinges on another variable, which leads to inferences that are scale dependent. In cointegration tests, testing unit root integration order is not applicable for models with at least one variable that is logarithmized.
