Let lnw lnw be the natural log of wage, fem fem be the dummy variable for female, and educ educ be the years of schooling. We estimated the regression lnw=9.140.23fem+0.22educ0.03femeduc+ lnw = 9.14 0.23 fem + 0.22 educ 0.03 fem educ + e where femeduc fem educ represents the product of two variables.
