Convergence speed and diversity of nondominated solutions are two important performance indicators for Multi-Objective Evolutionary Algorithms (MOEAs). In this paper, we propose a Resource Allocation (RA) model based on Game Theory to accelerate the convergence speed of MOEAs, and a novel...

Prior studies on errors in reserve estimation suggest that insurers manage loss reserves to achieve corporate goals, including tax minimisation and income smoothing. Analysing U.S. property and casualty insurance industry data, we find a relationship between reserve errors and the purchase of...

Prior literature has indicated some advantage to physician-directed insurers in the medical malpractice insurance market (Lei and Browne, 2008, and Lei and Schmit, 2008, 2010). We anticipate that these advantages lead to enhanced financial performance, and test that hypothesis. We note, however,...
