Vertical price transmission in the Egyptian tomato sector after the Arab Spring

This study assesses price transmission along the Egyptian tomato food marketing chain in the period that followed the Arab Spring, which accentuated economic precariousness in Egypt. Static and time-varying copula methods are used for this purpose. Results suggest a positive link between producer, wholesaler and retailer tomato prices. Such positive dependence is characterized by asymmetries during extreme market events that lead price increases to be transferred more completely along the supply chain than price declines.     

Computer users’ ergonomics and quality of life – evidence from a developing country

This study is aimed at investigating the quality of workplace ergonomics at various Pakistani organizations and quality of life of computer users working in these organizations. Two hundred and thirty-five computer users (only those employees who have to do most of their job tasks on computer or laptop, and at their office) responded by filling the questionnaire covering questions on workplace ergonomics and quality of life. Findings of the study revealed the ergonomics at those organizations was poor and unfavourable. The quality of life (both physical and mental health of the employees) of respondents was poor for employees who had unfavourable ergonomic environment. The findings thus highlight an important issue prevalent at Pakistani work settings.     

Value Added and Corporate Control in the U.S.

This paper examines the ability of value added to assess the differences between target firms and their industries and to explain target firms' abnormal returns during the takeover period. In a sample of 234 completed takeovers over the period 1977 to 1989, takeover targets have lower value added to total assets ratios than other firms in their industries in the year preceding the year in which the takeover is completed. Target firm abnormal returns observed during the takeover period are positively related to the difference between target Firm and average industry value added to total assets. This suggests that while acquired firms are on average underperformers, acquiring firms value the access to, and possibly the ability to redistribute, the resources of target firms.     

Shrinkage estimation of the proportion in randomized response

This article considers the asymptotic estimation theory for the proportion in randomized response survey usinguncertain prior information (UPI) about the true proportion parameter which is assumed to be available on the basis of some sort of realistic conjecture. Three estimators, namely, the unrestricted estimator, the shrinkage restricted estimator and an estimator based on a preliminary test, are proposed. Their asymptotic mean squared errors are derived and compared. The relative dominance picture of the estimators is presented.     

INVESTOR EVALUATION OF OVERFUNDED PENSION PLAN TERMINATIONS

Hundreds of large firms have terminated overfunded pension plans and obtained substantial cash reversions in the past few years. This study reveals a positive and significant market reaction at the time of the termination announcement. The strongest stock price reaction is for firms with large terminations relative to prereversion income. This study demonstrates that real economic gains result from the termination. Specifically, firms terminating overfunded pension plans tend to have tax loss carryforwards that effectively increase the after-tax returns from termination.     

Patient empowerment strategies for a safety net

The Milwaukee County General Assistance Medical Program implemented strategies to improve the delivery of care to its patients that include patient education and a Nurse Telephone Line. The partnership between a county-funded program and an academic health center has been very productive and resulted in improvements to the program that benefit underserved patients. The outcomes of these educational strategies are described.     

Methodological challenges in hip fracture registration: the Harstad Injury Registry

The aim of the study was to evaluate a hospital-based injury recording system on hip fracture registration in elderly persons aged?+?65 years from 1994 through 2008, and to examine the agreement between the number of validated fractures and the number of fractures reported to the Norwegian Patient Registry using three different sources: (1) Medical records, (2) Patient administrative system and (3) The hospital's hip fracture record to the Norwegian Patient Registry from 2002 through 2008. The injury recording system included 582 hip fracture events and 535 (92%) were confirmed through the medical records. Reasons for non-verification were different coding failures. Searching the patient administrative system using ICD codes identified 16 hip fractures not included in the fracture registry between 2002 through 2008. The total number was the same as the number of hip fractures reported to the Norwegian Patient Registry using ICD codes alone for identification. The conclusion is that on well-defined diagnosis like hip fractures, local fracture registries may obtain a high degree of reliability if different sources are available for quality control. Well-functioning patient administrative systems may be used to study numbers of hip fractures.     

Shrinkage estimation for the mean of the inverse Gaussian population

We consider improved estimation strategies for a two-parameter inverse Gaussian distribution and use a shrinkage technique for the estimation of the mean parameter. In this context, two new shrinkage estimators are suggested and demonstrated to dominate the classical estimator under the quadratic risk with realistic conditions. Furthermore, based on our shrinkage strategy, a new estimator is proposed for the common mean of several inverse Gaussian distributions, which uniformly dominates the Graybill–Deal type unbiased estimator. The performance of the suggested estimators is examined by using simulated data and our shrinkage strategies are shown to work well. The estimation methods and results are illustrated by two empirical examples.     

Corporate Social Reporting Practice: Evidence from Listed Companies in Bangladesh

This article presents an empirical investigation into the corporate social reporting practices of listed companies from Bangladesh, where corporate social reporting is a matter of voluntary disclosure. Analysis of annual reports published in 2007 reveals that only 15.45% of listed companies made such disclosures. This article presents an extensive survey of the contents, form, nature, and extent of corporate social reporting practices of listed companies. Analysis over a wide range of industries reveals that companies in the banking sector secure the highest rank in terms of corporate social reporting; three fourths of all disclosures are generalized qualitative statements without any attempt at attestation; more than one half of the disclosures are located in the director's report; and the mean amount of disclosures was less than half a page.
