Purpose – The purpose of this editorial is to consider the existence and implications of epistemological constraints in the field of risk finance arising from statistical inequalities similar to the Cramér-Rao lower bound (CRLB) of statistical estimation theory and the Heisenberg uncertainty...

Purpose – The purpose of this paper is to consider the existence and significance of heavy-tailed – and in particular, infinite-mean – insurance losses. Design/methodology/approach – Three specific questions are addressed in turn. First, how do infinite-mean insurance losses arise in the...
