It is found that a discriminatory tariff policy is inferior to a uniform tariff policy in terms of the social welfare of the importing country or the welfare of the world as a whole if the cost disadvantage of the licensor firm is high. This result is robust even if the licensor firm can engage in R&D investment in the long-run. © 2016 City University of Hong Kong and National Taiwan University.Discriminatory tariffs; international technology licensing; R&D; uniform tariff; welfare[SDGs]SDG1[SDGs]SDG9journal article10.1080/16081625.2016.1188451
