报告摘要：
This study develops a simple framework of supply for cryptocurrencies to quantify the role of electricity prices by examining cryptocurrency miners’ optimization. Cryptocurrency miners optimally adjust the supply of cryptocurrencies to changes in electricity prices. The optimal condition infers cryptocurrency returns from miners’ exposure to changes in electricity prices. Our empirical analysis confirms the model implications and shows that the rolling–window exposure of cryptocurrency returns to percentage changes in electricity prices (βM) can positively predict the cross–section of future cryptocurrency returns across major exchanges. Further evidence reveals that the predictive power of βM is more pronounced when estimating βM with electricity prices from mining–intensive regions. A global risk–in–mining factor can explain, across different cryptocurrency exchanges, a series of well–documented cryptocurrency anomalies including the ones regarding cryptocurrency market capitalization and momentum.
