Exchange Rate Policy and Welfare

China has been accused of intentionally depressing the value of its currency, the renminbi, to gain unfair advantages in the global market. This paper investigates whether China can benefit from arbitrarily lowering the yuan peg to the dollar in a two-country framework. If China is a small country, a change in the yuan’s peg has no effect on the relative price of China’s exportable good, and hence it does not affect China’s welfare. If China is a large country, China’s optimal policy is yuan appreciation, not devaluation. While producers and consumers behave as price takers in the world market, Chinese government can lower the yuan’s peg to the U.S. dollar, which effectively raises the relative price of China’s exportable good. A numerical example using the Cobb-Douglas utility function illustrates the main proposition.
