According to Economist Magazine, adding rising labor cost, Chinese Yuan has appreciated by nearly 50% against US dollar since 2005.
A real exchange rate takes account of price movements in each country. If prices rise faster in China than in America, China’s real exchange rate goes up, even if its nominal exchange rate stays the same. That’s because higher prices at home make China’s firms less competitive abroad, just as if their currency had gone up.To calculate the real exchange rate, you need a gauge of prices in each country. Many economists use the consumer-price index (CPI). But the CPI contains lots of goods and services (such as housing rents) that cannot be traded across borders.
Our measure of the real exchange rate, which we will regularly update, offers a more direct measure of competitiveness by looking instead at unit labour costs: the price of labour per widget. These costs go up when wages rise or productivity (widgets per worker) falls. In American manufacturing, unit labour costs have risen by less than 4% since the first quarter of 2005, according to the Bureau of Labour Statistics. In Chinese industry they have risen by 25% over that period, according to our sums.
