Testing regression coefficients after model selection through sign restrictions
AbstractFollowing a general-to-specific modelling strategy, empirical economists sometimes delete variables with "wrong" signs from a regression equation. Such an elementary model selection step may affect subsequent inference. We determine the post-model-selection [PMS] effect analytically and numerically.
