May 2006Stabilization of Effective Exchange Rates Under Common Currency Basket Systems
with Junko Shimizu: w12198
We investigate the extent to which a common currency basket peg would stabilize effective exchange rates of East Asian currencies. We use an AMU (Asian Monetary Unit), which is a weighted average of ASEAN10 plus 3 (Japan, China, and Korea) currencies, as a common currency basket to investigate the stabilization effects. We compare our results with another result on stabilization effects of the common G3 currency (the US dollar, the Japanese yen, and the euro) basket in the East Asian countries (Williamson (2005)). We obtained the following results: first, the AMU peg system would be more effective in reducing fluctuations of the effective exchange rates as more countries applied the AMU peg system in East Asia. Second, the AMU peg system would more effectively stabilize the effective excha...
November 2000On the Desirability of a Regional Basket Currency Arrangement
with Takatoshi Ito: w8002
This paper considers a theoretical model to examine an optimal exchange rate regime for (Asian) emerging market economies that export goods to the U.S., Japan, and neighboring countries. The optimality of the exchange rate regime is defined as minimizing the fluctuation of trade balances, in the environment where the yen-dollar exchange rate fluctuates. Since the de facto dollar peg regime is blamed as one of the factors that caused the Asian currency crisis, the question of the optimal exchange rate regime is quite relevant in Asia. The novelty of this paper is to show how an emerging market economy's choice of the exchange rate regime (or weights in the basket) is dependent on the neighboring country's. The dollar weights in the currency baskets of the two countries are determined as a N...
August 1999How Did the Dollar Peg Fail in Asia?
with Takatoshi Ito, Yuri Nagataki Sasaki: w6729
In this paper we have constructed a theoretical model in which Asian firms maximize their profit, competing with Japanese and US firms in their markets. The duopoly model is used to determine export prices and volumes in response to the exchange rate fluctuations vis-…-vis the Japanese yen and the US dollar. Then, the optimal basket weight to minimize the fluctuation of the growth rate of trade balance is derived. These are the novel features of our model. The export price equation and export volume equation are estimated for several Asian countries for the sample period of 1981 to 1996. Results are generally reasonable. The optimal currency weights for the yen and the US dollars are derived and compared with actual weights that had been adopted before the currency crisis of 1997. F...
