Measuring News Sentiment
This paper demonstrates state-of-the-art text sentiment analysis tools while developing a new time-series measure of economic sentiment derived from economic and financial newspaper articles from January 1980 to April 2015. We compare the predictive accuracy of a large set of sentiment analysis models using a sample of articles that have been rated by humans on a positivity/negativity scale. The results highlight the gains from combining existing lexicons and from accounting for negation. We also generate our own sentiment-scoring model, which includes a new lexicon built specifically to ...
Nowcasting Turkish GDP and News Decomposition
Real gross domestic product (GDP) data in Turkey are released with a very long delay compared with other economies, between 10 and 13 weeks after the end of the reference quarter. To infer the current state of the economy, policy makers, media, and market practitioners examine data that are more timely, that are released at higher frequencies than the GDP. In this paper, we propose an econometric model that automatically allows us to read through these more current and higher-frequency data and translate them into nowcasts for the Turkish real GDP. Our model outperforms nowcasts produced by ...
How Expectations About Future Productivity Drive Inventories
To what extent do expectations about future productivity developments drive business cycles? This Economic Brief reviews the state of the literature and discusses how new research by the authors establishes a novel method to answer. We specifically focus on firms' inventories, which stock goods available for future sales. We find that these inventories expand strongly to news about future productivity developments. This confirms that expectations about future productivity are a powerful force behind aggregate fluctuations, a finding with important implications for widely used economic models.
Can the News Drive Inflation Expectations?
How households expect inflation to evolve plays an important role in explaining overall inflation dynamics. Household expectations rose dramatically over the past year or so, much faster than professional forecasters’ inflation expectations. News coverage can explain part of this growing gap. Analyzing the volume and sentiment of daily news articles on inflation suggests that one-fourth of the increased gap between household and professional expectations can be attributed to heightened negative media coverage. These results highlight the important impact of the content and tone of economic ...
