Abstract

This paper proposes a new insurance model, called More for Less, as an alternative to (re)insurance. Briefly, the company charges more premiums than necessary from the insured, but it undertakes to reimburse part of them if there has been no claim. Our goal is to compare this model to a (re)insurance model by examining the finite-time ruin probabilities and the expected deficit at ruin. The approach adopted here is based on simple calculations of path integrals and properties of an underlying family of Sheffer polynomials. The main motivation is to offer a different insurance coverage in today’s changing world.
