Russian Accounting System: Value Relevance of Reported Information and the IFRS Adoption Perspective

In this paper I perform an empirical investigation into the value relevance of information reported by Russian public firms from two distinct perspectives. First, I document that prior to 2011, investors relied on information incorporated in the book value of equity. The value relevance of reported earnings, however, is different for “growth” versus “value” stocks. Second, I document that Russian leading firms listed on the London Stock Exchange that report in accordance with IFRS produce more value-relevant reports compared to their local peers that report under the Russian standards. This suggests that the mandatory IFRS adoption in Russia that will be completed by 2015 is likely to result in improved information quality.     

3D simulation technology as an effective instructional tool for enhancing spatial visualization skills in apparel design

The purpose of this study is to explore the effectiveness of 3D simulation technology for enhancing spatial visualization skills in apparel design education and further to suggest an innovative teaching approach using the technology. Apparel design majors in an introductory patternmaking course, at a large Midwestern University in the United States, participated in this study. Three different teaching methods (lecture, 3D simulation instruments, and paper patternmaking) were employed in consecutive instructional phases, within a single day. A short questionnaire devised to assess students’ visualization abilities and overall evaluation on the three different teaching methods was administered to the students after each of the three phases. Overall, students’ abilities to visualize 2D patterns onto a human body were improved by all three teaching methods. The 3D simulation instruments anchored positive effects of training on spatial visualization abilities between lecture and paper patternmaking practices. The results affirm that 3D simulation technology has positive potential as an efficient instructional tool for improving students’ visualization skills in apparel design.     

Product attributes and models of multiple discreteness

Demand for product characteristics is examined within the context of models that allow for both corner and interior solutions corresponding to zero and non-zero demand. Product attribute information is associated with marginal utility and curvature (satiation) parameters of various utility functions. Empirical applications demonstrate the need for incorporating characteristics in a fairly general way. We also compare our approach to an ideal point and pure Lancasterian versions of our nonlinear utility model. The data support our model over either the ideal point or Lancasterian variants.     

Liquidity, analysts, and institutional ownership

In this paper, we investigate the empirical relationship between institutional ownership, number of analysts following and stock market liquidity. We find that firms with larger number of financial analysts following have wider spreads, lower market quality index, and larger price impact of trades. However, we find that firms with higher institutional ownership have narrower spreads, higher market quality index, and smaller price impact of trades. In addition, we show that changes in our liquidity measures are significantly related to changes in institutional ownership over time. These results suggest that firms may alleviate information asymmetry and improve stock market liquidity by increasing institutional ownership. Our results are remarkably robust to different measures of liquidity and measures of information asymmetry.     

Policy Uncertainty and the Dual Role of Corporate Political Strategies

Firms use active political strategies not only to mitigate uncertainty emanating from legislative activity, but also to enhance their growth opportunities. We find that a firm's systematic risk (beta) can be hedged away by employing various political strategies involving the presence of former politicians on corporate boards of directors, contributions to political campaigns, and corporate lobbying activities. The hedging effect is greater when firms operate in more uncertain industries. In addition, active political strategies are associated with greater firm heterogeneity and make real options more value relevant as potential drivers of competitive advantages in uncertain environments.     

The extent of nonstationarity of beta

This paper investigates the extent of nonstationarity of beta across the firm size and the beta magnitude by suggesting the sequential parameter stationarity model and estimating change-points of betas. The high-beta firm has shorter stationary interval, which means that its beta changes more frequently than do the low-beta firm's. The firm size, however, does not have a monotonic relation with the length of stationary interval. The small and large firms have relatively shorter stationary interval than do the mid-sized firms. The average length of stationary interval is estimated about five years (exactly 54.19 months). This fact could support the currently widely-used arbitrary 5-year assumption of beta stationarity. The fluctuation of the large firm's beta is more severe than the small firm's, and the high- and low-beta firms have the relatively greater fluctuating betas than do the mid-beta firms. The frequency of detected change-points is found to be positively related to market returns. When the market return is high, the systematic risk changes more frequently, and vice versa.

Economic design of one-sided screening procedures based on a correlated variable with all parameters unknown

Summary Economic design of one-sided screening procedures for improving outgoing product quality based on a screening variable is considered for the case with all parameters unknown. It is assumed that the performance and screening variables are jointly normally distributed and that costs are incurred by screening inspection, acceptance of an imperfect item, and disposition of a rejected one. A method for finding optimal cutoff value based on the predictive distribution is presented.
