Abstract We re-examine the major tenets of the informational theory of legislative rules, focusing on the informational efficiency of rules with varying degrees of restrictiveness. When committees are heterogeneous, full efficiency is attainable under the unrestrictive open rule as well as the somewhat restrictive modified rule. In contrast, the restrictive closed rule always leads to inefficiencies. When committees are homogeneous, the situation is different.
All equilibria are inefficient regardless of legislative rules.
The closed rule, however, leads to greater informational efficiency than does the open rule. Further, the efficiency gains under the closed rule more than offset distributional losses regardless the degree of preference divergence. We also examine the incentives provided by the different rules for information acquisition and committee specialization. Download PDF file . When types are multi-dimensional the result follows from the Fundamental Theorem of Calculus once sufficient smoothness is assumed.
