Jean Lemaire is the Harry J. Loman Professor of Insurance and Risk Management at the Wharton School. He holds a BS in mathematics, a MS in actuarial science, and a Ph.D. in applied mathematics, all obtained at the Free University of Brussels. He joined the Wharton School in 1987 as Director of the Actuarial Science Program.

Jean Lemaire has published over 100 research papers and books in game theory and actuarial science. He has lectured on insurance regulation and actuarial science in over 60 countries. His 1985 book “Automobile Insurance: Actuarial Models” was the insurance book-of-the-year both in Europe and in the US. His books have been translated in French, Spanish, Mandarin, Russian, Japanese, and Korean.

Jean Lemaire is a winner of the 1988 International Prize of the Italian Academy of Science, the most important prize awarded to insurance researchers in terms of amount and prestige. In 2008 he was elected Honorary Chairman of ASTIN, the non-life section of the International Actuarial Association, and received the Wharton School’s Hauck Award for excellence in teaching. His current research interests include the study of merit-rating systems in automobile insurance, the impact of genetic testing on insurance, and the consequences of gun violence.

All Courses

  • BEPP4510 - Fund of Actuarial Sci I

    This course is the usual entry point in the actuarial science program. It is required for students who plan to concentrate or minor in actuarial science. It can also be taken by others interested in the mathematics of personal finance and the use of mortality tables. For future actuaries, it provides the necessary knowledge of compound interest and its applications, and basic life contingencies definition to be used throughout their studies. Non-actuaries will be introduced to practical applications of finance mathematics, such as loan amortization and bond pricing, and premium calculation of typical life insurance contracts. Main topics include annuities, loans and bonds; basic principles of life contingencies and determination of annuity and insurance benefits and premiums. This course may be taken concurrently with the prerequisite with instructor permission.

  • BEPP4530 - Actuarial Statistics

    This course covers models for insurer's losses, and applications of Markov chains. Poisson processes, including extensions such as non-homogeneous, compound, and mixed Poisson processes are studied in detail. The compound model is then used to establish the distribution of losses. An extensive section on Markov chains provides the theory to forecast future states of the process, as well as numerous applications of Markov chains to insurance, finance, and genetics. The course is abundantly illustrated by examples from the insurance and finance literature. While most of the students taking the course are future actuaries, other students interested in applications of statistics may discover in class many fascinating applications of stochastic processes and Markov chains. This course may be taken concurrently with the prerequisite with instructor permission.
