The main purpose of this paper is to estimate the volatility in global fertilizer prices. The endogenous structural breakpoint unit root test and alternative volatility models, including the generalized autoregressive conditional heteroskedasticity (GARCH) model, Exponential GARCH (EGARCH) model, and GJR model are estimated for six global fertilizer prices and the crude oil price. Weekly data f...

This study employs the asymmetric threshold cointegration test suggested by Enders and Siklos (2001) and creates EC-EGARCH(1, 1)M model to investigate the pass-through of money market rate to banking retail rates in Taiwan and Hong Kong. It further explores the impact of interest volatility on interest rates. Over the period of February 1988 to December 2004, we find that the interest pass-thou...

In this paper we conduct a close examination of the relationship between return shocks and conditional volatility. We do so in a framework where the impact of return shocks on conditional volatility is specified as a general function and estimated nonparametrically using implied volatility data—the Market Volatility Index (VIX). This setup can provide a good description of the impact of return ...
