Ajay Agrawal, Joshua Gans, Catherine Tucker, and I recently hosted the third NBER Conference in the Economics of Artificial Intelligence in Toronto. The conference provides a place for scholars from different fields of economics to discuss the implications of the rise of AI.

In the New York Times, there is a video opinion piece from Jaron Lanier which makes the case for finding a way for consumers to be paid for their data. I really enjoyed the accessibility of this piece as I think it helped make a clearer case. But I found myself with some big questions …
Nobody knows who organized the attack. It might have come from an angry gamer, or from a rogue spy, or, perhaps, an angry rogue spy playing games. The program hijacked many cameras and home devices, and redirected them to engineer a series of distributed denial of server (DDOS) attacks on a few hours apart, all …
Following a comprehensive report on market structure and antitrust, the Committee for the Study of Digital Platforms (at the Stigler Center at the University of Chicago) has released a report that I was a co-author on, on the media and regulatory options to enhance citizen welfare. Our main policy recommendations are: Introducing some public funding …
Many querulous conversations fan the flames in policy debates about artificial intelligence. Everyone agrees we are transitioning to something, but not on what that will be. Anyone want to venture a guess? It is safe to bet on widespread use of neural networks and deep learning. Anything else? Some futurists also forecast a confrontation between …
If someone had said that I would be writing a blog post to consider a law that might imprison people for conducting statistical analysis on publicly available data, I would have thought that was unlikely because who would ever propose, let alone enact, such a law? The other day we got our answer: France! The …

One of the popular travel options in Toronto is Porter Airlines which operates out of the City Airport and so is just 15 minutes from my University of Toronto office. Because it is a small airport, it is the kind of airport where you can literally leave an hour before your flight with no problems. …

The first issue of AER Insights is out and the very first article is one by Francesco Caselli and Alan Manning on "Robot Arithmetic: New Technologies and Wages." Here is the abstract: Existing economic models show how new technology can cause large changes in relative wages and inequality. But there are also claims, based largely …
