  • Product R&D Investment Policies in an International Duopoly

    Yumiko Taba, Yasunori Ishii

    REVIEW OF DEVELOPMENT ECONOMICS   20 ( 2 ) 574 - 582  2016.05

     View Summary

    This study analyzes the optimal product R&D investment policies of a developed and a developing country in an international Cournot duopoly where firms from these two countries compete through endogenous quality-quantity decisions. We explore a new international trade model by using demand functions derived from utility functions. We find that the optimal product R&D investment policies for both countries are subsidies. This study counters a finding that used Hotelling-type demand functions and it partially modifies another result that adopted the same demand functions but with an international Bertrand duopoly.

  • Export Competition between Landlocked and Coastal Countries: An Analysis of Strategic Export Policies

    Bakar Normizan, Ishii Yasunori

    REVIEW OF DEVELOPMENT ECONOMICS   18 ( 4 ) 804 - 812  2014.11

     View Summary

    This paper analyzes economic rivalry between two firms using an international Cournot duopoly model, where a firm from a landlocked country (LC) and a firm from a coastal country (CC) compete in a third-country market. It is assumed that the landlocked country firm adopts a transport-cost reducing R&D subsidized by its government, while the CC government imposes a toll fee on the LC firm. The findings show since a change in the LC's transport-cost reducing R&D subsidy has a positive effect on its export and a negative effect on the CC's export, both measures have effective strategic export policies.

  • Quality-Price Competition and Product R&D Investment Policies in Developing and Developed Countries

    Yasunori Ishii

    ECONOMIC RECORD   90 ( 289 ) 197 - 206  2014.06

     View Summary

    This study establishes a third-country trade model where firms from developing and developed countries invest into product R&D under their governments' subsidisation policies to analyse firms' quality-price choices and governments' optimal product R&D investment policies. We show that a rise in the developing (developed) country's product R&D subsidy makes firms' quality-price competition more (less) intense and that the governments' optimal product R&D policies, depending on the features of their quality and demand functions, can both be subsidies even under Bertrand price competition, contrary to the findings of previous studies.
