The ranking of multivariate volatility models is inherently problematic because it requires the use of a proxy for the … unobservable volatility matrix and this substitution may severely affect the ranking.

There is quite an extensive literature documenting the behaviour of stock returns volatility in both developed and … emerging stock markets, but such studies are scanty for the Nigerian Stock Exchange (NSE). Modelling volatility is an important … of stock return volatility of the Nigerian Stock Exchange returns using GARCH (1,1) and the GJR-GARCH(1,1) models …

This article focuses on the volatility of crude oil futures prices on the New York Mercantile Exchange. It aims at … examining whether this market creates excess volatility, which would not be observed in the absence of such a market. In order … process. We show that a significant part of the volatility recorded during exchange trading hours is caused by mispricing …

This paper studies the dynamics of volatility transmission between Central European currencies and euro/dollar foreign … exchange using model-free estimates of daily exchange rate volatility based on intraday data. We formulate a flexible yet … parsimonious parametric model in which the daily realized volatility of a given exchange rate depends both on its own lags as well …

This paper assesses the performance of the core inflation measures calculated by the Brazilian Central Bank (BCB). The evidence shows that they do not meet some key statistical criteria that a good core inflation should have: unbiasedness and the ability to forecast inflation. That performance...

In this article, a multivariate threshold varying conditional correlation (TVCC) model is proposed. The model extends the idea of Engle (2002) and Tse and Tsui (2002) to a threshold framework. This model retains the interpretation of the univariate threshold GARCH model and allows for dynamic...

In this paper we examine the forecasting performance of five nonlinear GARCH(1,1) models. Four of these have recently been proposed in literature, while the fifth model is a new one. All five models allow for switching persistence of shocks, depending on the value and/or sign of recent returns....
