Arthur J. Hosios *82

Arthur Hosios, professor of economics at the University of Toronto, died Nov. 17, 2018, of ALS at age 68.

Hosios earned a bachelor’s and a master’s degree in engineering from McGill University in 1972 and 1975, respectively. He then worked as a computer analyst in Montreal’s Royal Victoria Hospital, and his first eight publications were in the biomedical engineering field.

He began his doctoral studies at Princeton in 1978 and earned a Ph.D. in economics in 1982. He had joined the University of Toronto as a lecturer in 1981 and began publishing in the top journals of economics. Hosios chaired his department for a decade, and the department flourished under him.

His most widely cited paper, published in 1990, yielded the “Hosios Condition,” wherein he laid out the conditions for the efficient matching of workers and firms. This became a start for a still flourishing literature on search models of the labor market.

More recently, he applied himself to a broader range of activities. He was an adviser to communities in significant land-claims cases against the Canadian government. He also worked in quantitative humanities.

Hosios is survived by his wife, Louise; and two children, Ilana and Aaron ’11.
