周五晚的Happy hour是和同事胡说八道的开心时刻，这次遇到的老板和同事都很好，每天都在哈哈哈之余，也会传授很多过来人的经验给我。还有就是几乎每天都有人请Tea，摸鱼还能有那么好待遇真的会不好意思。回家路上看见餐厅有Steak night，而且价钱还挺便宜就迈不动腿了。[哈哈]最后，最近的stock终于有点起色了，虽然可能是波期到了，Anyway新的一年，还是得搞钱！

This work explores the impact of economic policy uncertainty on stock market uncertainty using empirical analysis during the COVID-19 epidemic. It constructs a GARCH type of model to measure the daily skewness of S&P 500 for the tail risk of the U.S. stock market and measures economic uncertainty using three indices including the EPU (Economic Policy Uncertainty Index), EMU (Equity Market-related Economic Uncertainty Index), and EMI (Equity Market Volatility: Infectious Disease Tracker).
