Description: This model arose from a project to evaluate the cost of a health care access' program to provide comprehensive medical care to uninsureds in Minnesota, for the Minnesota Health Care Access Commission. The project was to provide estimates of the impact on per-person and aggregate costs for various participation percentages in the access program. In order to evaluate those costs, the antiselection model described in this was developed. Of note, this was the ACTUARIAL EDUCATION AND RESEARCH FUND 1991 PRACTITIONERS AWARD WINNER. From Actuarial Research Clearing House 1991, VOL. 2.

Description: This brief article describes an actuarial model of continuing care retirement communities [CCRC] that was developed. The model uses a set of multiple-decrement, multi-life, multi-status functions to describe the population of a CCRC.

Description: There are many investigations probing the relationship between health outcomes [such as mortality rate, fertility rate] and economic variables [such as rise in income] and other variables [such as level of education, availability of clean water]. Usually, these results are demonstrated using data from countries where economic conditions are improving over time along with health outcomes. This paper studies the links between health risks and the current economic conditions in Mexico where general mortality conditions improved during the period 1980-2000 but income fell.

Description: The differences between select and ultimate insurance mortality are usually explained in terms of: 1. deterioration of a person's physical condition which occurs due to aging, and 2. anti-selection which occurs as some policyholders allow their coverage to lapse [i.e., those policyholders who find their health has become poor keep their coverage, while those who remain healthy discontinue their insurance]. This paper explores the differences in mortality between companies related to the differences in lapse rates of the companies.

Description: This report looks at closed form models or 'exact solutions' in which calculus produces 'simple' formulae. The conclusion is that for Gaussian interest rate models we can solve the problem of an American option provided the option holder behaviour can be described by a force of option exercise which is linear or quadratic in the state variables.
