Nowcasting euro area GDP with news sentiment: a tale of two crises
ECB 2021.11.30 원문보기
This paper shows that newspaper articles contain timely economic signals that can materially improve nowcasts of real GDP growth for the euro area. Our text data is drawn from ?fteen popular European newspapers, that collectively represent the four largest Euro area economies, and are machine translated into English. Daily sentiment metrics are created from these news articles and we assess their value for nowcasting. By comparing to competitive and rigorous benchmarks, we ?nd that newspaper text is helpful in nowcasting GDP growth especially in the ?rst half of the quarter when other lower-frequency soft indicators are not available. The choice of the sentiment measure matters when tracking economic shocks such as the Great Recession and the Great Lockdown. Non-linear machine learning models can help capture extreme movements in growth, but require su?cient training data in order to be e?ective so become more useful later in our sample.
