David Edward Card (born 1956) is a Canadian labour economist and Professor of Economics at the University of California, Berkeley.
Card earned his Bachelor of Arts degree from Queen's University in 1978 and his Ph.D. degree in Economics in 1983 from Princeton University.
From 1988 to 1992, Card was Associate Editor of the Journal of Labor Economics and from 1993 to 1997, he was co-editor of Econometrica. He was the recipient of the 1995 John Bates Clark Medal, awarded to "that American economist under the age of forty who is judged to have made the most significant contribution to economic thought and knowledge." He gave the 2009 Richard T. Ely Lecture of the American Economic Association in San Francisco. Along with N. Gregory Mankiw, he was elected vice president of the American Economic Association for 2014.
In the early 1990s, Card received much attention for his finding, together with his then Princeton University colleague Alan B. Krueger that, contrary to widely accepted beliefs among economists, the minimum wage increase in New Jersey did not result in job reduction of fast food companies in that state. While the methodology (see difference in differences) and its claim has been disputed by some (see minimum wage for discussion), many economists, including Joseph Stiglitz, accept Card and Krueger's findings.
