The apparent fact that interactive effects are more common in policy innovations taking a long time to diffuse among the states, contrary to the presumed effects of interaction, suggests the existence of alternate diffusion mechanisms. Some policies diffuse directly from a federal model, while others diffuse among states via a segmented pattern of emulations. The order of state adoption of fair employment practices legislation is compared with the adoption order for three labor policies and two civil rights policies. Fair employment practice, by this test, is identified as a civil rights policy and not as a labor policy. State minimum wage legislation is discussed as a case of federal influence in the diffusion process. A first wave of diffusion was followed by a period of federally inspired court rescission. Federal legislation in 1938 began another wave of diffusion. In a third wave of innovations, states with existing laws amended those laws by emulating the new federal legislation.
