We propose a new method for estimating the power-law exponent of a firm size variable, such as annual sales. Our focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. As is well known, a firm size variable follows a power-law distribution...

Intermittent or multifractal behavior has been reported in various markets, and the impact of the COVID-19 pandemic has been investigated. However, the impact of the COVID-19 pandemic on global spot markets for staple foods has not yet been studied. We fill this gap by investigating the grain...
