United States

Abstract

This chapter analyzes the trends in speaking behavior in the United States Congress from 1921 to 2010 in the House and Senate. We find that key determinants of political behavior from the existing American and comparative literature (seniority, committee leader, party leadership, ideological extremism, and majority party membership) correspond to more floor speeches by members. Senators deliver more speeches per member than their counterparts in the House, although the determinants of activity are broadly similar. Splitting the results by historical period and examining the relationship by the polarization of the chamber show that the effects of certain variables have changed considerably over time. In the House, in particular, the effects of committee leader, extremism, and majority party status have increased over time while the effect of seniority has noticeably decreased in the post-Gingrich period.
