In prior research, the CDR model was invented and computed for cross-country relationships. This paper computes a CDR model based on published US state C, rankings in D, and rankings in R, taking into account the effect of interactions between C, D and R. The CDR model explains per capita real gross state product (GSP) adjusted for purchasing power parity (GSPppp) with three policy variables namely C, D and R. Geographical latitude (L) is also significant. The model is referred to as the CDR model because C, D and R are policy variables that can be changed by policy makers, while geography is outside the control of policy makers. %K CDR Index %K GSPppp %K Capitalism %K Democracy %K Rule of Law %K Entrepreneurship %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=141928
