We find new channels for the transmission of shocks in international currencies, by developing a model in which shock propagations evolve from domestic stock markets, liquidity, credit risk and growth channels. We employ symmetric and asymmetric copulas to quantify joint downside risks and...

This paper develops a robust portfolio optimization model based on regime switching R-Vine copulas, where regime switching R-Vine copulas capture asymmetric dependence and regime switching in financial markets. We consider the uncertainty in hidden economic states and define WSCVaR as CVaR in...

Risk management is an important and helpful process for investors, hedge funds, traders and market makers. One of its key points is the appropriate estimation of risk measures which can improve the investment decisions and trading strategies. The high volatility of cryptocurrencies turns them a...
