巨无霸汉堡包指数的中文解释

英国《经济学家》杂志编制的一个不是很严谨的指数。 该杂志比较麦当劳巨无霸汉堡包(Bid Mac)在世界各地的价格，作为各国币值是否被低估或高估的指南。其假设是相似的食品无论在哪里销售，其价格应当是相同的，价格有差别意味着币值出现异常情况。例如，一个巨无霸汉堡包在华盛顿的价格为1美元，而在鲁利坦尼亚(Ruritania，假想国)为20比索，那幺，美元兑比索应是1美元等于20比索。如果汇率偏离这一水平，根据购买力平价理论，比索的币值要幺偏低，要幺偏高。购买力平价理论认为，汇率应变动至令相同的商品组合价格一致的水平。批评者认为，巨无霸汉堡包指数忽略了不同国家的税收、利润水平和原材料价格等因素的影响。

Big Mac Index的英文解释

A light-hearted index devised by The Economist magazine which compares the price of McDonald's Big Mac burgers, a fast food stapleavailable around the world, as a guide to whether currencies are overvalued or undervalued. It's based on the assumption that similar goods should cost the same wherever they are purchased. If the prices are different there is an anomaly in the valuation of the local currency. For example, if a Big Mac costs $1 in Washington and 20 pesos in Ruritania then the dollar/peso exchange rate should be 20 pesos to the dollar. If it's out of line then the peso is either overvalued or undervalued on the basis of purchasing-power parity, which says exchange rates should move towards a level which equalizes the price of an identical basket of goods. Critics say the Big Mac index ignores the effects of taxes, profit margins and the price of raw materials in different countries.
