The impact of divided government on legislative production

It seems obvious that divided governments should produce less legislation than unified governments. Yet studies have consistently failed to find such an effect. Because almost all existing studies focus on the experience of the U.S. national government, the data have limited analysis to a consideration of executive-legislative division and ignore the impact of division between bicameral chambers. The state-level data set employed in this study is not so limited. The results show that divided legislatures decrease the production of laws by almost 30%. Nonetheless, consistent with previous studies using national-level data, executive-legislative divisions have no impact of legislative production. The reason for this asymmetry is theoretically motivated. Additional hypotheses of interest are also tested, including whether Republican-controlled legislative chambers are more "conservative" than Democratic chambers in the sense of producing fewer laws than their Democratic counterparts.
