This study examines the relationship between the value of financial analysts' recommendations and the intensity of firms' research and development (R&D) expenditures. We conduct univariate, portfolio and regression analyses using a sample of 8,620 public firms for the period 1993-2004. The...

We use a proprietary dataset to test the implications of several asymmetric information models on how short-lived private information affects trading strategies and liquidity provision. Our identification rests on information acquisition before analyst recommendations are publically announced....

This study constructs a novel measure that aims to capture face-to-face private communications between firm managers and sell-side analysts by mapping detailed, large-volume taxi trip records from New York City to the GPS coordinates of companies and brokerages. Consistent with earnings releases...

Sell-side research is a common source of corporate fundamental information, but most of the research is exclusively distributed to paying clients. This paper investigates whether the soft information in analyst reports exacerbates the information asymmetry among investors. I document that the...

Initial Coin Offerings (ICOs) provide a clean opportunity and rich data to study the contribution of analysts to the functioning of capital markets. The assessments of freelancing ICO analysts vary in quality and exhibit biases due to the reciprocal interactions of analysts with ICO team...

This paper studies how investors react to public messages that may be optimistically biased. We first construct a communication game between an investor and a (possibly) biased securities analyst. We find an equilibrium characterised by the following properties: first, the investor reacts more...

Freelancing human experts play an important role in Initial Coin Offerings (ICOs). Expert ratings partially reflect the reciprocal network of ICO members and analysts. Ratings predict ICO success, but highly imperfectly so. Favorably rated ICOs tend to fail when more ratings reciprocate prior...

We show that the growth and the burst of a financial bubble stem from positive feedback trading. However, the presence of overconfident traders and the risk aversion...

We use the presence of a Wikipedia article for initial public offering (IPO) firms to test theories of information asymmetry and investor awareness. While we find limited support for the former, our results provide strong support for theories of investor awareness. Specifically, IPO firms with a...
