Description: This is the abstract of a paper that builds on previous work concerned with measuring equity, and considers the problem of using observed claim data or other information to arrive at premiums which maximize equity. When these optimal premiums are used, it is shown that gathering more information or refining the risk classification must always increase equity.

Description: This abstract introduces the paper which uses credibility theory to analyze policyholder persistency. It is assumed that persistency depends on the difference between the premium charge and anticipated claims.

Description: This is the abstract for the paper on optimal reversible annuities to minimize the probability of lifetime ruin.
