Decision Making When Choices Are Complex: A Test of Heiner's Hypothesis
研究了决策者认知能力与决策难度之间的差距（C-D差距），通过统计分析验证了该差距的存在以及决策启发式的使用，并发现复杂性对福利分析有重要影响。
This paper explores Heiner's hypothesis concerning a gap between the cognitive ability of decision makers and the difficulty of decisions (the C-D gap). We discuss the implications of decision heuristics for coefficient estimates when uncertainty is faced by decision makers, where the level of uncertainty varies with complexity. Statistical analysis strongly supports the presence of a C-D gap and provides evidence supporting the use of decision heuristics. The results of both direct and indirect methods suggest that mixed decision strategies may be used. We also find that complexity effects can have important implications for welfare analysis.
