3 basic criticisms of R. J. Cebula's "Local Government Policies and Migration: An Analysis for SMSA's, 1965-1970" (Public Choice, 1974, 19, Fall, 85-93) are offered: (1) it would have been more logical to use 1965 than 1971 welfare values for the period covered in the analysis, (2) since causality with respect to welfare & migration may run in both directions, migrants who moved over the 1965-70 period may have influenced welfare levels, & (3) since tax & government spending are "rather highly correlated," one of them should have been dropped from the equation or a multiequation model should have been used. A single equation estimation model taking account of these criticisms is presented, with separate results for white & black migrants, calculated for the same time period. R. J. Cebula (Emory U, Atlanta, Ga) in LOCAL GOVERNMENT POLICIES AND MIGRATION: REPLY AND EXTENSION accepts these criticisms & results as interesting & relevant. He offers a simultaneous-equation model which shows: (A) interactive effects between migration & income levels, & (B) property taxes have an effect on migration patterns. He also notes that Kohn's variables (welfare & spending) have "the same signs & essentially the same significance levels" as those in the original paper. J. N. Mayer.
