Adios, Andrew Coulson

Neal McCluskey  and Jason Bedrick mark Andrew Coulson's passing, far too early. Andrew and I corresponded some years ago via email and he  he asked if I would send the statistics I had compiled on the relation between age (start) of compulsory attendance and NAEP test scores (positive. Later is better) and district size and NAEP test scores (negative. Smaller is better). He said that he would pass these to Caroline Hoxby, a far more statistically sophisticated analyst than I. Perhaps she needed a laugh. Coulson's  Market Education makes the historical case that the education industry thrives without State (government, generally) compulsory attendance, subsidy, regulation, or direct operation.
