We study the economic policy spillovers using framework developed by Diebold & Yilmaz (2009). Our main contribution is the analysis of the system of economic policy uncertainty spillovers at different persistence of frequency responses to shocks and to various magnitude of shocks. Mainly the...

Heavy tails and volatility clusters are both stylized facts of financial returns that destabilize markets. The former are extreme events by definition and the latter can accelerate adverse market developments. This work disentangles the two sources and examines which one does the greater damage...

In this paper, we analyzed a dataset of over 2000 crypto-assets to assess their credit risk by computing their probability of death using the daily range. Unlike conventional low-frequency volatility models that only utilize close-to-close prices, the daily range incorporates all the information...

This paper proposes an Exponential HEAVY (EHEAVY) model, which specifies the dynamics of returns and realized measures of volatility in an exponential form. The model ensures positivity of volatility and allows for asymmetric effects without restrictions on parameters, hence is more flexible. A...

This study examines the potential influence of exogenous shocks on time-varying correlations and portfolio strategies between the Asian emerging and other global stock markets including developed and other emerging markets. Using the ARMA-cDCC-FIEGARCH model with and without exogenous shocks,...

This paper examines volatility transmission between the spot and futures bitcoin markets. We use daily series over a sampling period that spans from December 2017 to September 2022. We examine several events that spread severe risk in cryptomarkets, such as the COVID-19 pandemic in 2020,...

Does Indian sovereign yield volatility reflect economic fundamentals, or whether it is a self-generated force flowing through markets with little connection to such fundamentals? To answer the question, this research explores the volatility dynamics and measures the persistence of shocks to the...

The crumble of financial markets due to the recent crises has wobbled precariousness in the stock market and intensified the returns vulnerability of banking indices. Against this backdrop, this study intends to model the volatility of the Indian Bank Nifty returns using a battery of GARCH...

This paper constructs a global tail risk (GTR) index and examines the role of GTR in predicting the volatility of international stock markets. Our empirical results emphasize that GTR contains valuable information to predict the stock volatility of group 7 (G7) countries. In addition, accounting...
