In this study we investigate the usefulness of historical accounting reports (10-Ks and 10-Qs) by examining four settings where we expect investors to acquire historical reports in order to obtain qualitative and quantitative information that contextualizes and conditions information released in the current period. Using a novel dataset that tracks user requests for accounting reports stored in the SEC EDGAR database, we find that requests for historic reports during the fiscal year are positively associated with financial reporting complexity and that requests around earnings announcements are positively associated with accounting discretion and negative earnings shocks (particularly for conservative firms). Finally, we find that daily requests for historical reports are positively associated with shocks to firm value (particularly negative shocks). Overall, our evidence suggests that historical reports make up an important component of the information mosaic assembled by investors.

This study examines whether the information content of earnings announcements – abnormal return volatility and abnormal trading volume – increases in countries following mandatory IFRS adoption, and conditions and mechanisms through which increases occur. Findings suggest information content increased in 16 countries that mandated adoption of IFRS relative to 11 that maintained domestic accounting standards, although the effect of mandatory IFRS adoption depends on the strength of legal enforcement in the adopting country. Utilizing a path analysis methodology, we find evidence of three mechanisms through which IFRS adoption increases information content: reducing reporting lag, increasing analyst following, and increasing foreign investment.

Using a novel data set that tracks all web traffic on the SEC 's EDGAR servers from 2008 to 2011, we examine the determinants and capital market consequences of investor information acquisition of SEC filings. The average user employs the database very few times per quarter and most users target specific filing types such as periodic accounting reports; a small subset of users employ EDGAR almost daily and access many filings. EDGAR activity is positively related with corporate events (particularly restatements, earnings announcements, and acquisition announcements), poor stock performance, and the strength of a firm's information environment. EDGAR activity is related to, but distinct from, other proxies of investor interest such as trading volume, business press articles, and Google searches. Finally, information acquisition via EDGAR , both to obtain earnings news and to provide context for it, has a positive influence on market efficiency with respect to earnings news. Overall, our results are important because they provide a unique, user‐based perspective on investor access of mandatory disclosures and its impact on price formation.

The objective of this study is to investigate factors that influence investor information demand around earnings announcements and to provide insights into how variation in information demand impacts the capital market response to earnings. The Internet is one channel through which public information is disseminated to investors and we propose that one way that investors express their demand for public information is via Google searches. We find that abnormal Google search increases about two weeks prior to the earnings announcement, spikes markedly at the announcement, and continues at high levels for a period after the announcement. This finding suggests that information diffusion is not instantaneous with the release of the earnings information, but rather is spread over a period surrounding the announcement. We also find that information demand is positively associated with media attention and news, and is negatively associated with investor distraction. When investors search for more information in the days just prior to the announcement, preannouncement price and volume changes reflect more of the upcoming earnings news and there is less of a price and volume response when the news is announced. This result suggests that, when investors demand more information about a firm, the information content of the earnings announcement is partially preempted.

We examine whether Delaware is a domestic tax haven. We find that taxes play an economically important role in determining whether U.S. firms locate subsidiaries in Delaware and that a Delaware-based state tax avoidance strategy lowers state effective tax rates by between 0.7 and 1.1 percentage points, on average. The tax savings represent a 15–24% decrease in the state income tax burden and translate to an increase in net income of 1.04–1.47%. However, we find that the tax benefits of Delaware tax strategies are diminishing over time in response to initiatives by state governments to limit multistate tax avoidance.

We investigate systematic changes in corporate effective tax rates over the past 25 years and find that effective tax rates have decreased significantly. Contrary to conventional wisdom, the decline in effective tax rates is not concentrated in multinational firms; effective tax rates have declined at approximately the same rate for both multinational and domestic firms. Moreover, within multinational firms, both foreign and domestic effective rates have decreased. Finally, changes in firm characteristics and declining foreign statutory tax rates explain little of the overall decrease in effective rates.

We examine the timing of returns around the publication of anomaly trading signals. Using a database that captures when information is first publicly released, we show that anomaly returns are concentrated in the first month after information release dates, and these returns decay soon thereafter. We also show that the academic convention of forming portfolios in June underestimates predictability because it uses stale information, which makes some anomalies appear insignificant. In contrast, we show many anomalies do predict returns if portfolios are formed immediately after information releases. Finally, we develop guidance on forming portfolios without using stale information.
