We examine whether rational investor responses to information uncertainty (IU) explain properties of and returns to several financial anomalies (post-earnings announcement drift, value-glamour, and accruals anomalies). Consistent with a rational learning explanation, we find that: (1) higher IU signals have more muted initial market reactions; (2) extreme anomaly portfolios are characterized by...

I examine whether managerial stock and options holdings influence the propensity of goingpublic firms to manipulate financial information, as measured by the incidence of shareholder class action lawsuits and discretionary accruals. Examining a sample of U.S. firms that went public during the years 1996-2006, I find some evidence that firms in which top managers receive large stock options gran...

We outline a spreadsheet-based system for visualization of real-time financial information. Our system permits the user to define arithmetic and presentation relationships amongst the various cells of the spreadsheet. The cells contain primitives that can be numbers, text, images, functions, and graphics. Presenting financial information in this format allows its intended clients, the financial...

We present a novel synthesis of Fisher information and asset pricing theory that yields a practical method for reconstructing the probability density implicit in security prices. The Fisher information approach to these inverse problems transforms the search for a probability density into the solution of a differential equation for which a substantial collection of numerical methods exist. We i...

Public disclosures can level information asymmetry in financial markets by removing informed traders’ advantage, or can exacerbate asymmetry by further increasing these traders’ knowledge of the firm. This study finds evidence of the latter phenomenon in earnings conference calls, where management releases new information, and financial analysts on the call immediately respond and question mana...

Empirical evidence shows word-of-mouth communication has real effects on trading patterns in financial markets. On top of that, the social network through which the information conveys also plays a crucial role. We propose a framework that allows informed traders to directly and truthfully communicate information in four major social interaction structures represented by circle, tree, star and ...

With Decision X/3, A, paragraph 8(c) "invites parties, relevant organisations and initiatives [...] to submit information concerning innovative financial mechanisms that have potential to generate new and additional financial resources as well as possible problems that could undermine achievement of the Convention's three objectives [...]". This submission focuses on experiences with offset pro...

This paper analyzes the market for financial information and the incentive of institutions, such as Reuters, to provide information to traders in decentralized financial markets. We derive the following results. (i) The optimal selling strategy consists of selling identical information (Reuters’ screen) to all traders. (ii) The traders buy information from the same providers. If the traders may...

BACKGROUND AND OBJECTIVE Accreditation is usually a voluntary program in which trained external peer reviewers evaluate a healthcare organization's compliance and compare it with pre-established performance standards. The aim of this study was to evaluate the impact of accreditation programs on the quality of healthcare services METHODS We did a systematic review of the literature to evaluate...
