In some countries, bicameral discrepancies are solved by the formation of a conference committee. In Chile, conference committees are exclusively and automatically formed when the second chamber rejects a bill passed in the first chamber or when the first chamber rejects the modifications to its original bill made by the second chamber. This article postulates 4 hypotheses for the determinants of conference committee formation. It tests them for the case of Chile’s sequential legislative process (1990–2018) using 2,183 bills that reached the stage where a conference committee could be formed. The 482 conference committees that resulted were more likely to be formed when chambers were controlled by different majorities, when passage required special voting thresholds, when bills were more important for the president, and when the bills had more approved amendments, but they were not more likely if the bill was introduced by legislators rather than the executive.

两院制冲突的决定因素：1990-2018 年智利会议委员会的形成

在一些国家，两院制分歧通过成立会议委员会来解决。在智利，当第二议院否决第一议院通过的法案或第一议院否决第二议院对其原议案的修改时，会议委员会将自动成立。本文对会议委员会形成的决定因素提出了 4 个假设。它使用 2,183 项法案对智利的顺序立法程序（1990-2018 年）进行了测试，这些法案达到了可以成立会议委员会的阶段。当议院由不同的多数控制时，当通过需要特殊投票门槛时，当法案对总统更重要时，更有可能形成所产生的 482 个会议委员会，
