9780792399957 English 0792399951 This book is different from all other books on Life Insurance by at least one of the following characteristics 1-4. 1. The treatment of life insurances at three different levels: time-capital, present value and price level. We call time-capital any distribution of a capital over time: (*) is the time-capital with amounts Cl,, ..., C at moments Tl, T, .., T resp. N 2 N For instance, let (x) be a life at instant 0 with future lifetime X. Then the whole oO oO life insurance A is the time-capital (I, X). The whole life annuity a is the x x time-capital (1,0) + (1,1) + (1,2) + ... + (I, 'X), where 'X is the integer part ofX. The present value at 0 of time-capital (*) is the random variable T1 T TN Cl V + v, + ... + CNV . (**) In particular, the present value ofA 00 and a 00 is x x 0 0 2 A = and a = 1 + v + v + ... + v'X resp. x x The price (or premium) of a time-capital is the expectation of its present value. In particular, the price ofA 00 and ax 00 is x 2 A = E( ) and a = E(I + v + v + ... + v'X) resp., This concise self-contained book on life contingencies is written for students, teachers, researchers and life insurance practitioners. The stochastic model, introduced by Professor De Vylder more than twenty years ago and now widely adopted, is used throughout the monograph. Beyond the classical material of life insurance mathematics, the emphasis lies on variance evaluations of mathematical reserves, allowing the estimation of long term ruin probabilities in life insurance portfolios with varying volume. Other characteristics of the book are its great generality, the inclusion of an axiomatic theory of compound interests, the development of statistical methods for mortality and other estimations, and the introduction of graphs making a clear visualization of multiple decrement models possible. This approach makes the monograph incomparable to other books in the field.
