We model and estimate ADRs’ home market pass-through and pricing-to-market using a regime-switching approach, which nests the two regimes in a conditional capital asset pricing model and treats any changes in these two regimes probabilistically. Our results from the 1998 to 2006 data show that the pricing-to-market regime dominates ADRs from China and Japan, whereas the home market pass-through regime dominates ADRs from Argentina and Germany when their respective home markets are volatile.
