David Card an HD recipient from the Univeristy of Guelph is one of 3 winners of Nobel prize for economics. 

David Card was born near Guelph and graduated with a BA from Queen’s University in 1978, followed by a PhD from Princeton in 1983. He is a Canadian Citizen, resident in the U.S. He is the Class of 1950 Professor of Economics at the University of California, Berkeley, having held positions at Princeton, Columbia and Chicago. He is the 1995 recipient of the American Economic Association’s ‘John Bates Clark Medal’ ✻ and the 2007 Frisch Medal of the Econometric Society. He is a Fellow of the American Academy of Arts and Sciences, the Econometric Society and the Society of Labor Economists, of which he was President in 2011.

David Card’s work is on empirical labour economics and has addressed some of the most important labour issues, informing both academic discussion and policy debate. He has made important contributions to scholarship and policy on education, minimum wages and the effects of immigration. Many of his findings have challenged the standard predictions of economics. In a widely-­‐cited study Card found no evidence that an increase in the minimum wage in New Jersey led to job losses in the fast-­‐food industry. Card’s work frequently makes use of ‘natural experiments’ where a policy change is made and the consequences observed – often with surprising results.

✻ The John Bates Clark Medal is awarded by the American Economics Association to "that American economist under the age of forty who is adjudged to have made a significant contribution to economic thought and knowledge". Named after the American economist John Bates Clark (1847-1938), it is considered one of the two most prestigious awards in the field of economics, along with the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel. HE NOW HOLDS BOTH AWARDS!
