“…The stationary price index is then P m = P ( c m , c m h , τ m ) , which evaluates (14) at the cutoffs for each state. 25 Similarly, the domestic component of the price index is P m, h = P h ( c m h ) so its change, P ˆ m, h , depends on changes in the domestic entry cutoff, c ˆ m, h . The import price index is P m, x = P x ( c m , τ m ) and therefore P ˆ m, x depends on the change in the cutoff and also in tariffs if τ m ≠ τ b .…”
