While the importing country has the incentive to impose tariffs on the goods coming from the two exporting countries, the export policies chosen by the exporting countries depend on the tariff regime, whether uniform or discriminatory tariffs are used. With complete information, it is argued that export taxes are chosen by both exporting countries in some cases, and that while the importing country prefers a uniform tariff regime, the exporting countries find a discriminatory tariff regime preferable. We also extend the Brander-Spencer (1985) framework to examine the non-cooperative Nash equilibrium of export subsidy policy under incomplete information when the firms’ costs are unknown to the exporting and importing countries. With the assumptions of linear demand and two types of a firm’s cost, the non-cooperative Nash equilibrium is that both exporting countries use a single pooling export subsidy (tax) under a uniform (discriminatory) tariff regime. Moreover, we find that the importing country would optimally choose a uniform tariff regime. However, both exporting countries prefer a discriminatory tariff regime as long as the expected cost differential between the two firms is small enough.application/pdf42999 bytesapplication/pdfzh-TW國立臺灣大學會計學系暨研究所策略性貿易政策出口補貼/出口稅關稅制度不完全資訊strategic trade policiesexport subsidies/taxestariff regimeincomplete Informationreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/18420/1/922415H002019.pdf
