Why are there liberal & conservative eras in Americans' policy preferences about race? In answering this question, I first develop a time-series measure of aggregate racial policy preferences by compiling multiple indicators of racial policy preferences into a single composite measure. Next, I propose a new model in which shifts in the tenor of media coverage of race -- focusing on the core values of egalitarianism & individualism at different times -- leads the public to prefer more or less active government policies on race. I test the model using data from Newsweek magazine & include appropriate controls for potentially confounding factors, such as generational replacement, policy mood, feedback from the policy process, & economic sentiment. 4 Tables, 3 Figures, 1 Appendix, 28 References.

AbstractIt is understood that ensuring equation balance is a necessary condition for a valid model of times series data. Yet, the definition of balance provided so far has been incomplete and there has not been a consistent understanding of exactly why balance is important or how it can be applied. The discussion to date has focused on the estimates produced by the general error correction model (GECM). In this paper, we go beyond the GECM and beyond model estimates. We treat equation balance as a theoretical matter, not merely an empirical one, and describe how to use the concept of balance to test theoretical propositions before longitudinal data have been gathered. We explain how equation balance can be used to check if your theoretical or empirical model is either wrong or incomplete in a way that will prevent a meaningful interpretation of the model. We also raise the issue of "
$I(0)$
balance" and its importance.

Research has detailed the potential link between exposure to the mass media and the process of developing attitudes. Less examined, however, are the consequences of differing levels of media consumption on the nature of attitudes at both the individual and aggregate levels. This paper assesses the relationship between media consumption and public opinion in the U.S. (expressed through the macro concept of Policy Mood and an analogous micro concept we call policy liberalism). At the individual level, we find that increased levels of newspaper readership reduce variance in opinion, but that increased levels of television viewership do not. At the aggregate level, our results show that the opinions of media-consuming subgroups move in parallel for the most part, with similar causal dynamics. A slight exception to this parallelism lies with those who barely, if ever, read newspapers. Adapted from the source document.
