 More recently, the discussion has moved to ethical analyses of international surrogacy arrangements. These have typically involved commissioning parents from high-income countries and surrogate mothers from poorer populations in less wealthy countries, including India and Thailand. The vast power differentials between the parties, expanded roles for surrogacy agencies brokering the arrangements, and loose regulatory regimes have made for heightened concern about exploitation and other potential wrongs (Panitch 2013, and see discussion in Purdy 1989, Wilkinson 2016).
