Crediting Invisible Work: Congress and the Lawmaking Productivity Metric (LawProM)

Congressional observers have long been interested in the distinction between legislative “workhorses” and “showhorses.” However, when scholars operationalize this by measuring legislator productivity, they often neglect many realities of modern lawmaking by focusing on the traditional bill sponsorship and passage process. To better align measurement with practice, we compile widely available data on bill sponsorship, cosponsorship, and amendments; we also use text-as-data methods to credit instances of behind-the-scenes lawmaking via text reuse between bills. We weight achievements from each of these lawmaking methods to create the Lawmaking Productivity Metric for House Members of the 101–113th Congresses. Including methods of lawmaking beyond bill sponsorship provides important insights about who the congressional workhorses are. In particular, we find that traditional measures systematically undercount the legislative successes of women and likely Black Members of Congress because they disproportionately legislate in less visible ways.
