Quantifying qualitative survey data with panel data
提出一种新方法，利用面板数据中的定量信息（如企业资产负债表）来量化定性调查中的预测，并以希腊制造业企业销售增长预测为例验证其有效性。
We develop a novel methodology to quantify forecasts based on qualitative survey data. The methodology is generally applicable when quantitative information is available on the realization of the forecasted variable, for example from firm balance sheets. The method can be applied to a wide range of panel datasets, including qualitative surveys on firm-level forecasts or household expectations. As an application, we employ a panel of Greek manufacturing firms and quantify firms' forecast errors of own sales growth. In this context, we conduct a variety of exercises to demonstrate the methodology's validity and accuracy.
