Research Abstract

We have developed an international trading model in which one importing goods industry and one non-trade goods model exist. A fixed number of firms operate in these two industries and move from one industry to another one. Each firm engages in Cournot competition in each industry. The government in this country can impose a tariff against goods imported. The economic welfare is defined as a sum of producer surplus, consumer surplus and tariff revenue. The optimal tariff rate is defined as the rate at which the economic welfare is maximized. We have established that the optimal tariff rate is smaller when firms can move among industries than when the firms can not move
政府がこの利益を最大にする関税率を最適関税と呼ぶ。国内企業が産業間を移動できる時は襲来の企業が産業を移動できない時に比べて最適関税率が低くなることを示した
