Speed hierarchy not only motivates fast trading competition on less precise information but also renders slower traders more informative. As a result, endogenous speed acquisition in equilibrium affects how information is produced and spread. When information diffusion is characterized by its...

Countercyclical dispersion of firm outcomes (micro dispersion) is commonly used as a proxy for micro uncertainty. In this paper, we characterize conditions under which micro dispersion and micro uncertainty co-move positively in the context of a large Cournot economy with dispersed information...

Certification by online analysts and early investors can generate excitement among potential token investors, leading to successful initial coin offerings (ICOs). We test the general notion of "wisdom of crowds" using novel data on nearly 3,400 ICOs, including sequential investor subscriptions...

Quarterly earnings conference calls convey fundamental information, as well as manager and analyst opinion about the firm. We examine how market uncertainty regarding firm valuation is affected by conference call tones. Using textual analysis of all publicly available earnings calls (2002-2012)...

This paper provides an up-to-date review and summary of the existing literature on the informational aspects of price processes. A common feature of these models is that prices reflect information that is dispersed among many traders. The paper begins by contrasting the Rational Expectation...

This paper examines how technological innovations drive fast trading investment for both speculators and exchanges and their impact on market. The negative externality of the speed acquisition from fast speculators can result in excessive investment, which is intensified as speculators' speed...

This paper develops a finite-period model of rational bubbles where trade of an asset takes place through a chain of middlemen. We show that there exists a unique equilibrium, and a bubble can occur due to higher-order uncertainty. Under reasonable assumptions, the equilibrium price is...

We propose an information-based theory to explain time variation in liquidity and link it to a variety of patterns in asset markets. In "normal times," the market is fully liquid and gains from trade are realized immediately. However, the equilibrium also involves periods during which liquidity...

This paper shows that firms talking less about the future in their annual reports generate positive abnormal returns of about 5% annually. I measure how much companies talk about the future in their annual 10-K reports by the frequency of the verbs will, shall, and going to. The evidence favors...

There is a continuum of agents, each of whom trades a divisible asset via demand function competition. Individual valuations are determined by multiple idiosyncratic and common shocks, regarding which the agent observes multi-dimensional signals. The only assumptions are that the signals are...
