英文文献摘要：
The economic impacts of food safety events are an ongoing concern for the food industry and policymakers. Animal disease outbreaks can be characterized by prolonged abnormal returns and greater price variability in livestock markets. We investigate the return and volatility patterns in live cattle and lean hog futures following BSE and H1N1 outbreaks by modeling time‐varying volatility and spillover effects between these substitutes. We find that cattle and hog futures markets were affected during these outbreaks with decreasing returns and increasing volatility. Volatility of hogs is found to reduce cattle volatility, providing evidence for price stabilization across linked markets.
