This paper studies the unconditional effects of a general policyintervention, which includes location-scale shifts and simultaneous shifts asspecial cases. The location-scale shift is intended to study a counterfactualpolicy aimed at changing not only the mean or location of a covariate but alsoits dispersion or scale. The simultaneous shift refers to the situation whereshifts in two or more covariates take place simultaneously. For example, ashift in one covariate is compensated at a certain rate by a shift in anothercovariate. Not accounting for these possible scale or simultaneous shifts willresult in an incorrect assessment of the potential policy effects on an outcomevariable of interest. The unconditional policy parameters are estimated withsimple semiparametric estimators, for which asymptotic properties are studied.Monte Carlo simulations are implemented to study their finite sampleperformances. The proposed approach is applied to a Mincer equation to studythe effects of changing years of education on wages and to study the effect ofsmoking during pregnancy on birth weight.
