Applications should be an invaluable experimental source of information and challenges for AI research. The real world always stretches the limitations of our AI systems, pointing toward new research themes in many areas. In the process of implementing an application, the designer continually makes choices based on (1) the baseline architecture used to implement the application, (2) the charact...

We study how M&As shape analysts’ coverage decisions and whether this process reveals information about the valuation and future performance of the merged firms.

We analyze the benefits in terms of scientific impact deriving from international collaboration, examining both those for a country when it collaborates and also those for the other countries when they are collaborating with the former. The data show the more countries there are involved in the collaboration, the greater the gain in impact. Contrary to what we expected, the scientific impact of...
