Logrolling in Congress

Working Paper: CEPR ID: DP18111

Authors: Marco Battaglini; Valerio Leone Sciabolazza; Eleonora Patacchini

Abstract: We study vote trading among U.S. Congress members. By tracking roll-call votes within bills across five legislatures and politicians' personal connections made during the school years, we document a propensity of connected legislators to vote together that depends on how salient the bill is to the politicians' legislative agenda. Although this activity does not seem to enhance U.S. Congress members' legislative effectiveness, vote trading is a strong predictor of future promotions to position of leadership.
