Ebook Earnings management and investor protection: an international comparison

Submitted by wulan on Thu, 04/29/2010 - 05:50

This paper provides comparative evidence on corporate earnings management across 31 countries. At a descriptive level, we find large international differences across several earnings management measures, including loss avoidance and earnings smoothing. Our descriptive evidence suggests that firms in countries with developed equity markets, dispersed ownership structures, strong investor rights, and legal enforcement engage in less earnings management. We then delve deeper and present an incentives-based explanation for these patterns.

Based on prior research that identifies investor protection as a key institutional factor affecting corporate policy choices (see Shleifer and Vishny, 1997; La Porta, Lopez-de-Silanes, Shleifer, and Vishny, 2000), we focus on investor protection as a significant determinant of earnings management activity around the world. We argue that strong and well-enforced outsider rights limit insiders’ acquisition of private control benefits, and consequently, mitigate insiders’ incentives to manage accounting earnings because they have little to conceal from outsiders. This insight suggests that the pervasiveness of earnings management is increasing in private control benefits and decreasing in outside investor protection. Our empirical results are consistent with this prediction and suggest that investor protection plays an important role in influencing international differences in corporate earnings management.

Ebook Peak Oil and Our Future An Overview and Personal Perspective

Submitted by antoq on Mon, 01/19/2009 - 08:03

This is an essay about Peak Oil, energy depletion, and the effects these issues will have on our lives. The information may come as a rude shock to many of you, and disrupt your sense of comfort and security. I apologize for that up front. The decision to write this was difficult, and it was not easy to compose. I will describe several energy supply trends and possible economic outcomes that I hope will not unfold in dramatic or chaotic ways. But in the end, I feel that the potential for these things happening and their possible consequences are simply too important to not pass on. It is not my intention to scare you or make you feel uncomfortable, but rather provide information and food for thought that you, your family, friends, and community might find helpful.

Aeronautics Ebook: Mixing in gas phase turbulent jets

Submitted by acrobat on Sun, 10/19/2008 - 07:35

This free ebooks is an experimental investigation of the mixing of the nozzle fluid of a round, turbulent jet with the entrained reservoir fluid, using laser-Rayleigh scattering methods. The measurements, at Reynolds numbers of 5,000 and 16,000, cover the axial range from 20 to 90 jet exit diameters and resolve the full range of temporal and spatial concentration scales. The measured mean and rms values of the concentration, and the mean scalar dissipation rate, when estimated from the time derivative of concentration, are consistent with jet similarity laws. Concentration fluctuation power spectra are found to be self-similar along rays emanating from the virtual origin of the jet, and are consistent with the universal form of scalar spectra proposed by Gibson (1968 II). The probability density functions for the concentration, the time derivative of concentration, and the square of the time derivative of concentration, are compiled and are also found to be self-similar along rays. Features of the measured distributions and spectra are consistent with the existence of large-scale structures within the flow that span the local diameter of the jet's turbulent cone. On the centerline of the jet, the scaled probability density function of jet gas concentration is found to be almost independent of the Reynolds number while the local mixing rate in the inner part of jet is not. The usual assumptions concerning isotropy and correlation of derivatives are found to lead to erroneous results for the probablility density function of the scalar dissipation rate.
