Duration: June 2022 - September 2024
Despite the key influence of news coverage on the financial markets, there has been no large-scale examination of this across different countries. In this project, we use semantic fingerprinting, a novel language processing technology, to translate qualitative description in news articles to quantitative measures. We develop a “news intensity” measure, study its impact on the volatility of stock markets over 24 countries, its relationship with economic policy uncertainty and investors’ attention.
Funder: Fritz-Thyssen Foundation
Duration: May 2008 - April 2011
This project explores the dynamics of current account imbalances and the corresponding saving-investment relationship. We introduce new bounded stationarity tests to assess the sustainability of these imbalances. Our results indicate that current account imbalances follow stochastic trends within their natural bounds. Additionally, we present a novel factor-based bootstrap inference for functional coefficient models. Using this approach, we find that the saving-investment relationship is influenced by key economic variables, including population growth, the age dependency ratio, and economic openness.
