Taking the Measure of Congress: Reply to Chiou and Rothenberg

e-mail: binder{at}gwu.edu Chiou and Rothenberg raise important questions about how tomeasure key concepts in the study of legislative stalemate inthe U.S. Congress. In challenging my choice of measures to capturebicameral differences, Chiou and Rothenberg argue that my findingsare the artifact of measurement error. In this reply, I reviewthe hurdles involved in measuring policy views over time andacross institutions and suggest that the preferred measure ofChiou and Rothenberg falls short for measuring bicameral differences.Second, I assess the extent to which measurement choices affectthe robustness of my findings about the determinants of gridlock.Drawing on new measures and model specifications, I show thatmy results are robust to alternative specifications. I concludewith an assessment of the broader challenges posed by how wemeasure critical concepts in the study of congressional performance.
