|The variable env_con (environmental concern) was accidentally reverse coded in ops2004.dta. Thus the variable has a higher score for people who have less environmental concern. This makes the coefficients on page 270 have a sign that is opposite of what they should have. The remaining portion of the chapter is correct in terms of procedures and Stata code. The interpretation is correct if the coding error is ignored and we assume that higher values of env_con correspond to more environmental concern.|
