GARCH model has gained popularity during the last two decades, because of their ability to capture non-linear dynamics in the real life data which we often observe especially in financial markets. This paper discuss four common information criteria (AIC, AICc, BIC and HQ) and their ability of correct selection in the presence of GARCH effect, based on their probability of correct selection as a...

Time varying correlations are often estimated with Multivariate Garch models that are linear in squares and cross products of returns. A new class of multivariate models called dynamic conditional correlation (DCC) models is proposed. These have the flexibility of univariate GARCH models coupled with parsimonious parametric models for the correlations. They are not linear but can often be estim...

This study investigates the intraday price and volatility spillover effect between the Japanese market and the Korean market, using a VAR-asymmetric BEKK GARCH model. In particular, the study considers three high-frequency (10-min, 30-min, and 1-hour) intraday datasets of TOPIX and KOSPI200 markets. The empirical results indicate a bi-directional price spillover effect in the 10-min intervals, ...

This paper stresses the importance of assessing the risk-return trade-off faced by environmental industries in financial markets. One of the most widely-used theoretical models in finance is the conditional CAPM, which describes the conditional risk-return tradeoff in financial markets, whereby both the conditional mean return and conditional beta risk are allowed to vary over time. This paper ...

Time varying correlations are often estimated with multivariate generalized autoregressive conditional heteroskedasticity (GARCH) models that are linear in squares and cross products of the data. A new class of multivariate models called dynamic conditional correlation models is proposed. These have the  exibility of univariate GARCH models coupled with parsimonious parametric models for the c...

نوسانات قیمت نفت به عنوان یک متغیر برون­زای قدرتمند، بسیاری از متغیرهای اقتصاد، از جمله شاخص قیمت سهام را می­تواند تحت­تأثیر قرار دهد. در این راستا، مطالعه حاضر در تلاش است با استفاده از مدل­های گارچ چند متغیره شامل مدل بابا، انگل، کرونر و کرافت (GARCH-BEKK) بر پایه روش موجک، اثرات سرریز بین بازارهای نفت و بورس اوراق بهادار تهران را به تفکیک دوران قبل از تحریم، بعد از تحریم و بعد از برجام به صو...
