The Laplace transform, density and moments of the time to ruin have been studied by many authors under different risk model assumptions. The Gerber-Shiu function provides an analytic tool in studying these quantities. The main focus of this thesis is to study the moments involving the time to ruin by using the Gerber-Shiu function as the analytic tool.enMomentsTime to ruinInsurance surplus analysisDoctoral ThesisActuarial Science
