A Bayesian Markov-Switching Correlation Model for Contagion Analysis on Exchange Rate Markets
用于汇率市场传染分析的贝叶斯马尔可夫切换相关性模型
This article develops a new Markov-switching vector autoregressive (VAR) model with stochastic correlation for contagion analysis on financial markets. The correlation and the log-volatility dynamics are driven by two independent Markov chains, thus allowing for different effects such as volatility spill-overs and correlation shifts with various degrees of intensity. We outline a suitable Bayesian inference procedure based on Markov chain Monte Carlo algorithms. We then…
