¹ Beginning with Dawson, Richard E. and Robinson, James A., “Inter-Party Competition, Economic Variables, and Welfare Policies in the American States,” Journal of Politics (05, 1963), 265–289 Google Scholar, there have been numerous articles and books on the subject. The most recent summary is: Fenton, John H. and Chamberlayne, Donald W., “The Literature Dealing with the Relationships Between Political Processes, Socio-economic Conditions and Public Policies in the American States: A Bibliographical Essay,” Polity (Spring, 1969), 388–394 Google Scholar.

⁵ There is a well established body of research on the diffusion of innovations from which I have drawn many insights. For general reviews of this literature see: Rogers, Everett M., Diffusion of Innovations (New York, 1962)Google Scholar, Katz, Elihu, Levin, Martin L., and Hamilton, Herbert, “Traditions of Research in the Diffusion of Innovations,” American Sociological Review (1963), 237–252 Google Scholar.

⁶ For examples see: Steiner, Gary A. (ed.), The Creative Organization (Chicago, 1965)Google Scholar; and Burns, Tom and Stalker, G. M., The Management of Innovation (London, 1961)Google Scholar.

⁷ There is much confusion over this distinction in the literature on diffusion. For an excellent discussion of the problem see: Mohr, Lawrence B., “Determinants of Innovation in Organizations,” this Review (1969), 111–126 Google Scholar.

⁸ Once the mistake was discovered, the Arkansas statute, which reproduced a model prepared by the National Association of Retail Druggists, was copied either verbatim or with minor changes by seventeen states. Grether, Ewald T., Price Control Under Fair Trade Legislation (New York, 1937), pp. 19–20 Google Scholar.

⁹ In later work I will report the results of comparisons of the diffusion patterns of issues from different subject matter areas. Preliminary efforts at such comparisons, however, have not revealed significant variations. There does not seem to be much difference in the diffusion patterns of issues of different types.

¹⁰ For a discussion of this phenomenon see: Edelman, Murray, The Symbolic Uses of Politics (Urbana, 1964), chapters 2 and 9Google Scholar.

¹¹ Lockard, Duane, Toward Equal Opportunity (New York, 1968), p. 23 Google Scholar.

¹² The beginning point for the existence of each state was the date upon which it was officially organized as a territory. Using this system, Oklahoma is the last state to come into being, having been organized in 1890. If a program began its diffusion before a state came into existence, that issue was not included in figuring the innovation score for the state.

¹³ Alaska and Hawaii were omitted from the analysis because data for their years of adoption were often missing.

¹⁷ Regional affects of this kind appear frequently in analyses of data from the American states. In many studies, especially those which involve measures of political participation or party competition, strong relationships appear which are actually only a result of the distinctive nature of the southern states. In order to insure that the correlations in this analysis were not merely a result of the social and political peculiarities of the South, the eleven states of the confederacy were removed from all distributions. Since the Southern states do not cluster at one extreme of the innovation scale, no great changes occurred in correlation coefficients based upon data from the thirty-nine states outside the South. Within the eleven Southern states, however, almost all the relationships were substantially reduced in size. Because only eleven states, are involved, this fact is difficult to interpret, but will be treated more fully in later work. For an example of this problem discussed in another context see: Wolfinger, Raymond and Field, John Osgood, “Political Ethos and the Structure of City Government,” this Review (1966), 306–326 Google Scholar. For a more extensive discussion of the methodological implications see the discussion of “interaction effects” in Forbes, Hugh Donald and Tufte, Edward R., “A Note of Caution in Causal Modelling,” this Review (1968), pp. 1261–1262 Google Scholar; and the communication from Dennis D.

²³ There is one other index in existence which deals with political phenomenon: Rodney Mott's Index of Judicial Prestige. The Mott index measures the degree to which state supreme courts were used as models by the legal profession. It is based on a study of citations in federal Supreme Court decisions and all state supreme court decisions, the number of cases reprinted in standard textbooks, and the opinion of a panel of prominent legal scholars; it covers the period 1900 to 1930. The Mott index and the innovation score from the same time period are correlated at .62. This finding might be interpreted to mean that emulative behavior in the judicial arena is not much different from that in the legislative arena. For details of the Judicial Prestige Index see: Mott, Rodney L., “Judicial Influence,” this Review (1936), 295–315 Google Scholar.

⁴¹ This is not the first study to discover the important role of emulation and competition in the development of public policy. Hofferbert, Richard in: “Ecological Development and Policy Change in the American States,” Midwest Journal of Political Science (1966), p. 485 Google Scholar; and Sharkansky, Ira in: “Regionalism, Economic Status and the Public Policies of American States,” Southwestern Social Science Quarterly (1968)Google Scholar both mention the influence of other states in the calculations of state decision makers. Several earlier students of local government complained that sparsely populated, arid Western states had blindly copied from the heavily populated Eastern states forms of local government which were inappropriately suited for the conditions prevailing in the Great Plains. See: Goodman, A. Bristol, “Westward Movement of Local Government,” The Journal of Land and Public Utility Economics (1944), pp. 20–34 Google Scholar; Walker, Herman Jr. and Hansen, Peter L., “Local Government and Rainfall,” this Review (1946), 1113–1123 Google Scholar.

⁵⁹ A small portion of the difference between the two columns in Table 6 is an artifact of measurement. Since not all the programs in this analysis have been adopted by all forty-eight states, laggard states sometimes remain. As time passes and programs receive widespread acceptance these laggard states slowly fall into line and adopt the programs. Since the programs in the first two time periods have been around longer, they have more likely completed their spread among lhe states and thus, given our scoring procedure; are also more likely to have a longer period of diffusion.
