摘要翻译:
我研究那些错误地感知随机序列中跨期相关性的人的内生学习动力学。有偏智能体面临一个最优停止问题。他们对底层分布不确定,并从前人那里学习其参数。当早期抽签“足够好”时,代理停止,所以前人的经验包含负面影响,但没有正面影响。当代理人错误地预期系统逆转(“赌徒谬论”)时,他们低估了连续低于平均水平的抽奖的可能性,对分布的均值收敛到过度悲观的信念,并过早停止。不确定分布方差的代理人高估它的程度取决于前人的停止阈值。我还分析了其他对跨期相关性的误解是如何与内生数据审查相互作用的。

英文摘要:
I study endogenous learning dynamics for people who misperceive intertemporal correlations in random sequences. Biased agents face an optimal-stopping problem. They are uncertain about the underlying distribution and learn its parameters from predecessors. Agents stop when early draws are "good enough," so predecessors' experiences contain negative streaks but not positive streaks. When agents wrongly expect systematic reversals (the "gambler's fallacy"), they understate the likelihood of consecutive below-average draws, converge to over-pessimistic beliefs about the distribution's mean, and stop too early. Agents uncertain about the distribution's variance overestimate it to an extent that depends on predecessors' stopping thresholds. I also analyze how other misperceptions of intertemporal correlation interact with endogenous data censoring.
