ABSTRACT
We quantified the impact of consumer awareness about beef safety on U.S. beef exports. An index to reflect consumer awareness is constructed based on publicized reports in the media. Results showed a 0.8% reduction in U.S. beef exports arose from foodborne-disease news. In addition, using impulse response functions derived from a panel vector autoregressive model (panel VAR with the system GMM estimator), we found that the negative impact of a shock in food safety news intensified after three quarters and then diminished. Investing in any scheme that minimizes the impact of food safety events, such as quality labeling, is suggested.

4 One noticeable fact is that when a food disease is recognized in an exporting country, although the country may regain its market share over time, it may have to switch from higher value markets to lower value markets. Lower value markets are those that have had food safety issues in the past. Webb, Gibson, and Strutt (Citation2018) provide more numerical details about this issue.
5 To estimate a panel VAR, we are not able to employ a standard fixed effect estimator because lagged endogenous variables lead to bias in panels. This bias can be overcome by using GMM or instrumental-variables estimators (Holtz-Eakin, Newey, and Rosen Citation1988).
