University of California, Berkeley Prof. Andrea Weber Department of Economics Spring 2008 Applied Exercise #3 – Due Thursday 03/20/08 – This exercise examines the return to education on wages in an instrumental variables framework, using college proximity as an instrument for education. It will be helpful to read the paper by David Card (1995) in the reader as you do this problem set. Feel free to work in groups. Each student must hand in their own solution to the problem set using own words to explain and interpret the results. Data: The data are drawn from the NLS Young Men Cohort. We have a sample of 14-24 year old men for whom the data contains information about family background, living arrangements, and region of residence in 1966. A follow up survey in 1976 provides information on educational attainment and earnings for the same individuals (for details see Card 1995). Access the data on bspace site for Econ C142: problem set 3/ nls.dta (STATA 9 format). The observational unit of the data is the individual. The data set has 3010 observations.
