"Our findings are quite contrary to expectations. We do not find any evidence that left-handed individuals earn less, as might be suggested by the literature referred to above which generally finds that left-handed people tend to suffer more from factors that would reduce labor productivity. On the contrary, we find that left-handed individuals with higher levels of education have higher earnings than right-handed-individuals. More specifically, among the college-educated men in our sample, those who report being left- handed earn 15 percent more than those who report being right-handed. The size of this effect is economically and statistically significant." "...Left-handers have a 3.5 percent greater return to a year of education than right-handers, whose return to a year of education is 4.6 percent; hence left-handers have a return of education of 8.1 percent (= 3.5 + 4.6). We therefore pursue this education difference in detail." "We still estimate a 15.9 percentage point larger increase in wages for left- than right-handed men for completing some college, and a 26 percentage point larger increase for completing college (in both cases compared to completing no college)." "The difference occurs only in the group with 16 or more years of education: of men entering college, those that are left-handed have a return to completing a college education that is 16.4 percentage points higher than the 23.4 percent return received by those that are right-handed."
