David Laidler

David Ernest William Laidler FRSC (born 12 August 1938, North Shields, England) is an English/Canadian economist who has been one of the foremost scholars of monetarism. He published major economics journal articles on the topic in the late 1960s and early 1970s. His book, The Demand for Money, was published in four editions from 1969 through 1993 (with slightly altered subtitles), initially setting forth the stability of the relationship between income and the demand for money and later taking into consideration the effects of legal, technological, and institutional changes on the demand for money. The book has been translated into French, Spanish, Italian, Japanese, and Chinese.

His continued work on the demand for money through the 1990s and into the 21st century (with William B. P. Robson) led to his receiving the Donner Prize in 2004 for Two Percent Target: Canadian Monetary Policy Since 1991, published by the C.D. Howe Institute, with which Laidler maintains a close working relationship.

His other major publication, Introduction to Microeconomics, was also published in four editions, from 1974 to 2008. It was translated into Spanish, Polish, Italian, and Bulgarian.

Later in his career, Laidler shifted focus to the history of economic thought. Despite being retired, he is still an active researcher and scholar.
