摘要

我们使用彭博平台上的一个新的季度汇率预测调查面板数据库,用于以下五种双边汇率:欧元/英镑、欧元/日元、欧元/美元、英镑/美元和美元/日元,时间跨度从2006年第三季度到2011年第四季度。我们发现,预测者平均而言是非理性的,他们无法识别双边汇率的真实数据生成过程,而且通常对过去观察到的信息反应过度。此外,通过对个人业绩的研究,我们可以发现,金融分析师非理性地不去审视他们过去的预测错误,以提高他们后来预测的质量。

Overreaction in Survey Exchange Rates Forecasts
We use a novel database of a panel of quarterly survey of exchange rates forecasts available on the Bloomberg platform, for the following five bilateral exchange rates: EUR/GBP, EUR/JPY, EUR/USD, GBP/USD and USD/JPY, for the timespan ranging from the third quarter 2006 up to the fourth quarter of 2011. We find that forecasters are on average irrational, failing to identify the true data generating process of bilateral exchange rates and generally overreacting to past observed information. Moreover, exploring individual performance, we can state that financial analysts irrationally do not look at their past forecast errors to improve the quality of their later forecasts.
