We stipulate a generalized gravity equation model to disentangle the effects of MRLs on the import demand and foreign exporters' supply. Applying the framework to the MRLs on pesticides imposed by high-income Organization for Economic Co-operation and Development countries, we find that the MRLs jointly enhance the import demand and hinder foreign exporters' supply. In addition, exporters from the less and least developed countries are more constrained by the MRLs than their competitors from the developed world. (JEL F14, Q17)
