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...

We compare the suitability of short-memory (ARMA models), long-memory (ARFIMA models), and a GARCH model to describe the volatility of rare earth elements (REEs). We find strong support for the existence of long-memory effects. A simple long-memory ARFIMA(0,𝑑,0) base model shows generally...

Rare earth elements (REEs) have become increasingly important because of their relative scarcity and worldwide increasing demand, as well as China's quasi-monopoly of this market. REEs are virtually not substitutable, and they are essential for a variety of high-tech products and modern key...

Ameriks, Caplin, Leahy & Tyler (2007) study how lack of self-control may lead to overconsumption and low wealth accumulation. For their analysis, the authors calculate difference scores from their survey questions. We review their study and highlight potential issues in the use of difference...
