Help within genetically related and unrelated organisms as well as investments of investors holding shares to different degree including charity can be understood within the ensemble concept. In an ensemble transfer of substrate from a source to a sink may result in superadditivity as well as...

A quantization method based on replacement of c-number by c-number parameterized by an unbiased hidden random variable is developed. In contrast to canonical quantization, the replacement has a straightforward physical interpretation as a statistical modification of classical dynamics of an...

In this paper, we test whether labor-hoarding environments with basic and augmented laws of motion provide an adequate explanation for observed business cycle dynamics. The basic law of motion assumes that the information set used by economic agents to forecast future forcing variables includes...
