In summary, Chapter 2 of my thesis finds that quantitative information from interim financial earnings disclosures fundamentally improves the earnings forecast accuracy of mechanical models and levels the playing field when comparing model forecasts to analyst forecasts. Similarly, quantitative financial disclosure information is a key input in most bankruptcy prediction models. Using web crawling techniques to aggregate bankruptcy information of German companies, Chapter 3 shows that the reliability of widely used bankruptcy prediction models is determined by the quality of the underlying bankruptcy data. Accordingly, bankruptcy prediction models can be improved by collecting accurate bankruptcy data and discarding incorrect information. Complementary, Chapter 4 applies a new perspective to information provided in corporate disclosures by examining qualitative or textual content. This section introduces a novel framework focusing on analysis of the textual content of annual reports. Using the immediacy of market reactions and investor responses to textual information enables quantifying the qualitative content of financial disclosures.
