內容介紹：
This paper examines the impact of monetary policy shocks on the exchange rate in the New Zealand context using an event-study approach. Monetary policy shock is considered as the unexpected change in monetary policy. Since March 1999 the Reserve Bank of New Zealand (RBNZ) has adopted Official Cash Rate (OCR) as the monetary policy instrument. Therefore, the present research uses changes in OCR expectations as the measure of monetary policy shock. In view of Zettelmeyer (2004), short-term interest rate changes are sifted to obtain those that are generated by OCR surprises by way of instrumental variable regressions. This implies that short-term interest rates can be the channel for OCR surprises to enter the currency exchange market. Our results indicate that a positive monetary policy shock, measured as an increase in the instrumented short-term interest rates, resulted in a depreciation of the exchange rate during the pre- and post-Global Financial Crisis (GFC) period, which is evidence for the exchange rate puzzle (ERP). During the GFC period, the ERP was absent, which lends support to Dornbusch’s (1976) overshooting hypothesis and uncovered interest parity.
