dc.description.abstractThis paper examines the relationship between vitamin usage and self-assessed health of United States residents and addresses the issue of endogeneity of vitamin use. First, preliminary OLS regressions are run, which ignore endogeneity. Then two instruments are introduced in two separate bivariate probit models. Finally, a di fference in di fferences probit regression is run using data from years 1986 and 2006. The two data sets used in this paper are the 1986 National Health Interview Survey and the 2006 National Health and Nutrition Examination Survey. Vitamin usage was found to be signi cant in all regressions that do not ignore endogeneity.
