Conference calls held in conjunction with an earnings release have become increasingly common in recent years, yet there is little evidence regarding the reasons that these calls are incrementally informative over the accompanying press release. Using a sample of more than 10,000 conference-call transcripts, we examine the information content of both segments of the call—the presentation and the discussion segment. We find that both segments have incremental information content over the accompanying press release. However, discussion periods are relatively more informative than presentation periods, and this greater information content is positively associated with analyst following. We also find that managers provide increased disclosures during the presentation segment when firm performance is poor, but relatively more information is released during discussion periods in these circumstances. Overall, our results are consistent with the notion that active analyst involvement in conference calls increases the information content of the calls, particularly when firm performance is poor.

We investigate a key assumption underlying much of the experimental research in financial accounting that graduate business students are a good proxy for nonprofessional investors. To conduct our investigation, we categorize recent experimental studies in financial accounting, based on the relative level of integrative complexity inherent in each study's task. We then conduct experiments using two tasks, one that is relatively low in integrative complexity and one that is relatively high in integrative complexity, and compare the responses of two groups of M.B.A. students and nonprofessional investors. Our results suggest that using M.B.A. students as a proxy for nonprofessional investors is a valid methodological choice, provided researchers give careful consideration to aligning a task's integrative complexity with the appropriate level of M.B.A. student. M.B.A. students who have completed their core M.B.A. courses and are enrolled in or have completed a financial statement analysis course are a good proxy for nonprofessional investors in tasks that are relatively low in integrative complexity. Though less definitive, the majority of our tests also suggest that these students are a good proxy for nonprofessional investors in tasks that are relatively high in integrative complexity. However, care must be taken when using students in the first-year core financial accounting course. In tasks that are relatively low in integrative complexity, these students perform similarly to nonprofessional investors except when they are asked to make an investment decision. In tasks that are relatively high in integrative complexity, these students acquire information similarly to nonprofessional investors, but they do not appear to integrate the information in a similar manner.

In this study we use a unique dataset to examine whether professional and nonprofessional investors use different online quarterly financial information when making investment decisions, and whether the online information they use depends on whether they are researching a new investment or evaluating a current investment. Our results suggest that professional investors prefer to view PDF-formatted quarterly reports and tend to rely directly on the financial statements compared with nonprofessional investors who prefer to view HTML-formatted reports and have a tendency to rely more on management's discussion of the quarter's results. Our results also suggest that, for nonprofessional investors, investment familiarity (i.e., whether they are evaluating a current investment or researching a new investment) strongly affects the type of financial information they view within a firm's quarterly reports. Our results have implications for the design of experimental studies, and provide information useful to managers, financial report users, standard setters, and researchers as they attempt to better understand the types of information that professional and nonprofessional investors use when making investment decisions.

In this paper, we exploit the open nature of conference calls to explore whether managers withhold information from the investing public. Our evidence suggests that managers regularly leave participants on the conference call in the dark by not answering their questions. We find that the best predictors of such an event are firm size, a CEO's stock price–based incentives, company age, firm performance, litigation risk, and whether analysts are actively involved during the call's Q&A section. Finally, we document strong support for the assumption maintained in the literature that investors interpret silence negatively. That is, investors seem to interpret no news as bad news.
