Article analysis:

The article is generally reliable, as it provides evidence for its claims through the use of taxi ride records from New York City to measure private communication between firm managers and sell-side analysts. The study also controls for an extensive set of fixed effects (firm, analyst, year, and firm-broker) and other potential confounding factors, which helps to ensure the accuracy of the results. Furthermore, the article presents both sides of the argument equally by noting that the effects of increased ride volumes around EAD dissipate over longer horizons.

However, there are some potential biases in the article that should be noted. For example, the study only focuses on New York City, so it may not be applicable to other cities or regions. Additionally, while the article does control for a number of factors such as firm, analyst, year, and firm-broker fixed effects, there may still be other factors that could influence the results that have not been taken into account. Finally, while the article does present both sides of the argument equally by noting that effects dissipate over longer horizons, it does not explore any counterarguments or alternative explanations for its findings.
