- W2278201820 abstract "Rare earth elements (REEs) have gained increasing attention recently for several key reasons: 1) they are vital to many strategic industries, 2) they are relatively scarce, 3) they frequently exhibit high price fluctuations, 4) China holds a quasi-monopoly on their mining, and 5) China’s REE policy, which was overly restrictive and led to a formal complaint from the U.S., Japan, and the EU at the World Trade Organization (WTO) in 2012. This paper investigates whether the announcement of a WTO dispute resolution case can influence governmental changes in existing policies. We find empirical support for this notion, because REE prices exhibit a structural break around the announcement of a WTO dispute, and show lower variance ratios for all tested REEs afterward. This indicates a tendency toward efficiency, although REE prices still do not follow a random walk. Similarly, we find that the stock price informativeness of companies in the REE industry increases after such an announcement, reflecting more firm-specific than marketwide information and less governmental influence. Finally, we show that the model uncertainty for option pricing models decreases, which we measure by the lower pricing differences among them." @default.
