Spring 2008 UC Berkeley Department of Economics Andrea Weber Applied Exercise #1 – Due Thursday 02/21/08 – The focus of this exercise is on the relationship between educational attainment and earnings. It examines statistics that summarize the relationship between two random variables, the bivariate linear regression model, and the multivariate linear regression model. Feel free to work cooperatively and in groups. However, each student must hand in their own problem set using own words to explain the results. Try to summarize the answers/results concisely. STATA output may be attached to the end of the problem set for partial credit. Data: The data is an extract of a 1992 survey of German workers. It comes from the paper by John DiNardo and Steven Pischke “The returns to computer use revisited: Have pencils changed the wage structure too?" (1997). For more information see the reference to the paper on the reader. Access the data on bspace site for Econ C142: problem set 1/ restricted92.dta (STATA 9 format). The data set has 20,042 observations and 19 variables. The unit of observation is the individual. The key variables for this exercise are: - ed completed years of education - exp and exp2 years of labor market experience and its square (experience²) - female indicator variable equal to 1 if the person is female - mar indicator variable equal to 1 if the person is married - computer indicator variable equal to 1 if the individual uses a computer at work - pencil indicator variable equal to 1 if the individual uses a pencil at work - telefon indicator variable equal to 1 if the individual uses a telefon at work - calc indicator variable equal to 1 if the individual uses a calculator at work - hammer indicator variable equal to 1 if the individual uses a hammer at work - occ 4-digit occupational codes - lnw log of the hourly wage reported by the individual
