We investigate the potential historic decline in the information content of earnings announcements. Like Beaver (1968) we focus on the incremental information content of accounting earnings announcements—whether the announcements convey “new news” to the market as evidenced by unusual price movements. We investigate the price reaction to earnings announcements of a broad range of firms over a 23-year time period (1975 through 1997). We find that, on average, the price reaction to earnings announcements has increased over time. However, the robustness of this finding is called into question based on two factors. First, we find that the change in price reaction to earnings varies depending on the size of firms analyzed. Specifically, we find some evidence that small firms exhibit a decreasing price reaction to earnings announcements over time, while larger firms consistently exhibit an increasing price reaction to earnings announcements. Second, we find that a minority of firms drives the observed increase in price reaction indicating that a cross-sectional mean reaction does not imply such a reaction is typical for individual earnings announcements.

Text simplification (TS) reduces the complexity of the text to improve its readability and understandability, while possibly retaining its original information content. Over time, TS has become an essential tool in helping those with low literacy levels, non-native learners, and those struggling with various types of reading comprehension problems. In addition, it is used in a preprocessing stage to enhance other NLP tasks. This survey presents an extensive study of current research studies in the field of TS, as well as covering resources, corpora, and evaluation methods that have been used in those studies.

ABSTRACT            Based on the results of the 63 games played in each of the 32 NCAA Men’s Basketball Tournaments held from 1985 through 2016 it is shown that the information content of the seeding of the 64 teams invited to participate as to the seed of the eventual winner, varies from year to year, but not in any consistent fashion. The paper thus concludes that the Selection Committee’s seeding process has not improved over time, notwithstanding the availability of more sophisticated metrics for evaluating the teams’ regular-season performance. The fact that a 1-seed wins some 60 percent of the time and a top-three-seed wins 88 percent of the time only reflects the fact that the committee is not seeding the teams at random, but rather is exercising a modicum of judgment, aided and abetted by the tournament’s design.
