The distribution of attention across issues is of fundamental importance to the political agenda and outputs of government. This article presents an issue-based theory of the diversity of governing agendas where the core functions of government—defense, international affairs, the economy, government operations, and the rule of law—are prioritized ahead of all other issues. It undertakes comparative analysis of issue diversity of the executive agenda of several European countries and the United States over the postwar period. The results offer strong evidence of the limiting effect of core issues—the economy, government operations, defense, and international affairs—on agenda diversity. This suggests not only that some issues receive more attention than others but also that some issues are attended to only at times when the agenda is more diverse. When core functions of government are high on the agenda, executives pursue a less diverse agenda—focusing the majority of their attention on fewer issues. Some issues are more equal than others in executive agenda setting.

This paper provides the first systematic cross-country analysis of interest group appearances in the news media. The analysis included three countries -the UK, Spain and Denmark -each representing one of Hallin and Mancini's (2004) three overall models of media and politics: the liberal system, the polarized pluralist system and the democratic corporatist system. We find important similarities across countries with high levels of concentration in media coverage of groups, more extensive coverage of economic groups than citizen groups and differential patterns of group appearances across policy areas and between right-leaning and left-leaning papers. However, we also identify country variation, with the highest degree of concentration among group appearances in Spanish newspapers and most attention to economic groups in Danish newspapers.3

Abstract.A growing body of work has examined the relationship between media and politics from an agenda-setting perspective: Is attention for issues initiated by political elites with the media following suit, or is the reverse relation stronger? A long series of single-country studies has suggested a number of general agenda-setting patterns but these have never been confirmed in a comparative approach. In a comparative, longitudinal design including comparable media and politics evidence for seven European countries (Belgium, Denmark, France, Netherlands, Spain, Switzerland and the United Kingdom), this study highlights a number of generic patterns. Additionally, it shows how the political system matters. Overall, the media are a stronger inspirer of political action in countries with single-party governments compared to those with multiple-party governments for opposition parties. But, government parties are more reactive to media under multiparty governments.

This article outlines both the overall structure of the INTEREURO Project (Comparative Research on Interest Group Politics in Europe) and the theoretical foci, research activities and data sets generated by its several modules. We provide this description for two purposes. First, it provides a necessary backdrop for understanding the remaining essays in this special issue. Importantly, we do not believe that the methodological challenges we faced are unique to the INTEREURO Project. Rather, they characterize any large-N research project on interest representation. Thus, we hope that these articles based on the INTEREURO Project are useful to a broad range of scholars. Our second purpose is to describe for the wider community of interest organization scholars the INTEREURO Project and the data generated thereby.
