We study the polytopes of binary n-strings that encode (positive) integers that are not divisible by a partivular positive integer p - the indivisibility polytopes, as well as the more general "clipped cubes". Also, we discuss a potential application to factoring. Finally, we present some...

This study investigates the behaviour of the components of the bid-ask spread around earnings announcements. We find that adverse selection cost component significantly increases surrounding the announcements while the inventory holding and order processing components significantly decline...

Statistical extreme value theory is concerned with the use of asymptotically motivated models to describe the extreme values of a process. A number of commonly used models are valid for observed data that exceed some high threshold. However, in practice a suitable threshold is unknown and must...
