Jan M. Hoem (born 17 April 1939) is a distinguished scientist in population studies. He was born in Kristiansund, Norway, studied actuarial science and mathematical statistics in Oslo, and was awarded a Dr.philos. in 1969. He became a lecturer at the University of Oslo and later moved on to found and head the Socio-Demographic Research Unit at Statistics Norway. From 1974 to 1981 he was Professor at the Laboratory of Insurance Mathematics at the University of Copenhagen, followed by a professorship in Demometry at Stockholm University. In 1999 he was appointed Director of the Max Planck Institute for Demographic Research in Rostock, Germany, a position he held until he retired in 2007.〔(Jan Hoem's Homepage at the Max Planck Institute for Demographic Research )〕 Currently he is working as Professor Emeritus at the Stockholm University Demography Unit〔(Jan Hoem's Homepage at the Stockholm University Demography Unit )〕 Before he took his Dr.philos degree, he published a book called “Basic Concepts of Formal Demography”,〔Oslo University Press (1967)〕 which became the standard introductory text in demography in Norway. His article on Markov chain models 〔Markov Chain Models in life insurance, ''Blätter Deutsch. Gesellsch.Versich.math.'' ()〕 has been named one of the four most significant papers in modern actuarial science. Hoem also made contributions to stochastic stable population theory,〔Stochastic stable population theory with continuous time,(with Niels Keiding). ''Scand. Act. J''. 1976 (3), 150-175 (1976)〕 demographic incidence rates,〔Demographic incidence rates. ''Theor. Popul. Biol''. 14 (3), 329-337. Bibliographic Note, 18 (2), 195 (1978)〕 and the statistical analysis of multiplicative models. He is best known for his work on event-history analysis - contributions that have helped shape demographic methodology.〔Purged and Partial Markov chains.''Scand. Act. J'' 1969 147-155 (1969)〕〔Classical demographic methods of analysis and modern event-history techniques". IUSSP: 22nd International Population Conference, Montreal, Canada, 1993, Volume 3, 281-291 (1993〕〔On Jan Hoem's 65th Birthday, statement by James Vaupel, ''Demographic Research'' ()〕 Later in his career, Hoem turned towards social demography. In his papers on the impact of social policies on fertility, Hoem showed that the stringent application of appropriate methods to individual-level data greatly improve our understanding of the link between public policies, demographic behavior, and demographic outcomes.〔Public policy as the fuel of fertility: effects of a policy reform on the pace of childbearing in Sweden in the 1980s". ''Acta Sociologica'' 36 (1), 19-31 (1993)() 〕〔Social policy and recent fertility change in Sweden". ''Population and Development Review'' 16 (4), 735-748 (1990)〕 In 2006 he was awarded the IUSSP Laureate Award in recognition of his achievements in scientific research.〔(IUSSP Laureate Award )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jan Hoem」の詳細全文を読む スポンサード リンク
