The Swiss Formula is a mathematical formula designed to cut and harmonize tariff rates in international trade. Several countries are pushing for its use in World Trade Organization trade negotiations. It was first introduced by the Swiss Delegation to the WTO during the current round of trade negotiations at the WTO, the Doha Development Round or more simply the Doha Round. Something similar was used in the Tokyo Round.〔(WTO: A simple guide — NAMA Negotiations )〕 The aim was to provide a mechanism where maximum tariffs could be agreed, and where existing low tariff countries would make a commitment to some further reduction. ==Details== The formula is of the form : where : ''A'' is both the maximum tariff which is agreed to apply anywhere and a common coefficient to determine tariff reductions in each country; : ''T''old is the existing tariff rate for a particular country; and : ''T''new is the implied future tariff rate for that country.〔(More Details on the Swiss Formula )〕 So for example, a value ''A'' of 25% might be negotiated. If a very high tariff country has a rate ''T''old of 6000% then its ''T''new rate would be about 24.9%, almost the maximum of 25%. Somewhere with an existing tariff ''T''old of 64% would move to a ''T''new rate of about 18%, rather lower than the maximum; one with a rate ''T''old of 12% would move to a ''T''new rate of about 8.1%, substantially lower than the maximum. A very low tariff country with a rate ''T''old of 2.3% would move to a ''T''new rate of about 2.1%. Mathematically, the Swiss formula has these characteristics: # As ''T''old tends to infinity, ''T''new tends to ''A'', the agreed maximum tariff # As ''T''old tends to 0, ''T''new tends to ''T''old i.e. no change in tariffs as it is already low 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Swiss Formula」の詳細全文を読む スポンサード リンク
