This paper introduces a new typology for measuring legislative agenda setting power, moving beyond traditional metrics that capture only one aspect.

New Measurement Approach:

The study proposes assessing four distinct outcomes: passing legislation you oppose (a "roll") or defeating legislation you support (an "impeccation") versus your own preferred cases of success and failure in shaping agendas.

Methodology:

Using original data from 85 American state legislative chambers, the Mexican Chamber of Deputies, and the Canadian House of Commons over recent years allows for comprehensive analysis across diverse contexts.

Findings & Implications:

The typology reveals how agenda setters' influence manifests in different ways—both advancing their preferred policies while potentially hindering others they oppose. This nuanced understanding helps political scientists track power dynamics more accurately.
