The Eighth Data Release of the Sloan Digital Sky Survey: First Data from SDSS-III

Abstract: The Sloan Digital Sky Survey (SDSS) started a new phase in 2008 August, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements of the baryon oscillation feature in the clustering of galaxies and the quasar Lyα forest, and a radial velocity search for planets around ~8000 stars. This paper describes the first data release of SDSS-III (and the eighth counting from the beginning of the SDSS). The release includes five-band imaging of roughly 5200 deg2 in the southern Galactic cap, bringing the total footprint of the SDSS imaging to 14,555 deg2, or over a third of the Celestial Sphere. All the imaging data have been reprocessed with an improved sky-subtraction algorithm and a final, self-consistent photometric recalibration and flat-field determination. This release also includes all data from the second phase of the Sloan Extension for Galactic Understanding and Exploration (SEGUE-2), consisting of spectroscopy of approximately 118,000 stars at both high and low Galactic latitudes. All the more than half a million stellar spectra obtained with the SDSS spectrograph have been reprocessed through an improved stellar parameter pipeline, which has better determination of metallicity for high-metallicity stars.

Accrual-Based and Real Earnings Management Activities Around Seasoned Equity Offerings

Abstract: We examine earnings management behavior around SEOs, focusing on both real activities and accrual-based manipulation. Although research has addressed the issues of earnings management around SEOs and earnings management via real activities manipulation, ours is the first paper to put these two issues together. We make three contributions to the literature. First, we document that firms use real, as well as accrual-based, earnings management tools around SEOs. Second, we show how the tendency for firms to tradeoff real versus accrual-based earnings management activities around SEOs varies cross-sectionally. We find that firms choices vary predictably as a function of the firms ability to use accrual management and the costs of doing so. Our model is a first step in examining how firms tradeoff between real versus accrual methods of earnings management. Third, we compare the economic costs of accrual versus real earnings management around SEOs, by examining the effect of each type of earnings management on the firms future performance. We provide the first evidence on this important issue by showing that the costs of real earnings management are likely greater than the costs of accrual earnings management, at least in the SEO context.
