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.

Accuracy of Deception Judgments

Abstract: We analyze the accuracy of deception judgments, synthesizing research results from 206 documents and 24,483 judges. In relevant studies, people attempt to discriminate lies from truths in real time with no special aids or training. In these circumstances, people achieve an average of 54% correct lie-truth judgments, correctly classifying 47% of lies as deceptive and 61% of truths as nondeceptive. Relative to cross-judge differences in accuracy, mean lie-truth discrimination abilities are nontrivial, with a mean accuracy d of roughly .40. This produces an effect that is at roughly the 60th percentile in size, relative to others that have been meta-analyzed by social psychologists. Alternative indexes of lie-truth discrimination accuracy correlate highly with percentage correct, and rates of lie detection vary little from study to study. Our meta-analyses reveal that people are more accurate in judging audible than visible lies, that people appear deceptive when motivated to be believed, and that individuals regard their interaction partners as honest. We propose that people judge others' deceptions more harshly than their own and that this double standard in evaluating deceit can explain much of the accumulated literature.

The Determinants of Corporate Board Size and Composition: An Empirical Analysis

Abstract: Many theories have been proposed to explain how corporate boards are structured. This paper groups these theories into three hypotheses and tests them empirically. We utilize a unique panel dataset that tracks corporate board development from the time of a firm's IPO through 10 years later. The data indicate that: (i) board size and independence increase as firms grow in size and diversify over time; (ii) board size - but not board independence - reflects a trade-off between the firm-specific benefits of monitoring and the costs of such monitoring; and (iii) board independence is negatively related to the manager's influence and positively related to constraints on such influence. These results are consistent with the view that economic considerations - in particular, the specific nature of the firm's competitive environment and managerial team - help explain cross-sectional variation in corporate board size and composition. Nonetheless, much of the variation in board structures remains unexplained even when all three hypotheses are combined, suggesting that idiosyncratic factors affect many individual boards' characteristics.

The Relation between Auditors' Fees for Non-Audit Services and Earnings Management

Abstract: This paper examines whether auditor fees are associated with earnings management and the market reaction to the disclosure of auditor fees. Using data collected from proxy statements, we present evidence that non-audit fees are positively associated with small positive earnings surprises, the magnitude of absolute discretionary accruals, and the magnitude of income-increasing and income-decreasing discretionary accruals. In contrast, audit fees are negatively associated with these earnings management indicators. These results are robust to a variety of alternative variable definitions and model specifications. Specifically, contrary to the claims of Ashbaugh et al. (2002), the results are robust to the use of performance-matched discretionary accruals. Moreover, contrary to the claims of Francis and Ke (2002), the results for small positive earnings surprises are robust regardless of whether the comparison group is all other earnings surprises or small negative earnings surprises. Our final set of results provide evidence of a significant negative association between non-audit fees and share values on the date the fees were disclosed, although the effect is small in economic terms.

Corporate governance in emerging economies: A review of the principal-principal perspective: Review paper

Abstract: Instead of traditional principal–agent conflicts espoused in most research dealing with developed economies, principal–principal conflicts have been identified as a major concern of corporate governance in emerging economies. Principal–principal conflicts between controlling shareholders and minority shareholders result from concentrated ownership, extensive family ownership and control, business group structures, and weak legal protection of minority shareholders. Such principal–principal conflicts alter the dynamics of the corporate governance process and, in turn, require remedies different from those that deal with principal–agent conflicts. This article reviews and synthesizes recent research from strategy, finance, and economics on principal–principal conflicts with an emphasis on their institutional antecedents and organizational consequences. The resulting integration provides a foundation upon which future research can continue to build.
