This paper examines the conditional heteroscedasticity of the yen±dollar exchange rate. A model is constructed by extending the asymmetric power autoregressive conditional heteroscedasticity model to a process that is fractionally integrated. It is found that, unlike the equity markets, the apprecia

Abstract
The effects of changes in the yen/dollar exchange rate on the Korean economy during the pre‐crisis and the post‐crisis periods are examined using VAR models. The results show that Korean industrial production does not respond significantly to the depreciation of the Japanese yen against the US dollar during the pre‐crisis period, but that it declines substantially and significantly during the post‐crisis period. The forecast error variance decomposition also confirms that the impact of yen/dollar exchange rate shocks in explaining Korean industrial production is negligible during the pre‐crisis period, but substantial in the post‐crisis period. These empirical results are interesting in that the free‐floating exchange rate regime adopted in the post‐crisis period may be inadequate to insulate the Korean economy from external shocks such as fluctuations in the yen/dollar exchange rate.

This paper tests the properties of the zloty-dollar exchange rate for the possible presence of unknown non-linearities. It concludes that there is strong evidence for the presence of an underlying non-linear process which is possibly chaotic. A non-linear model which allows for discrete switching be
