City of Discontent? The Influence of Perceived Organizational Culture,LMX, and Newcomer Status on Reported Bullying in a Municipal Workplace

Workplace bullying is a counterproductive behavior that has captured the attention of researchers in recent years. The extent of reported bullying behavior in US organizations varies however; it is estimated to affect 15% to 50% of workers with projected annual costs of over $40 billion including direct and indirect costs. Workplace bullying poses a serious ethical challenge by sending messages about appropriate conduct within the organization’s culture. In this study, we focus on environmental factors as predictors of self-reported bullying in a public-sector organization. Specifically, the factors of interest are organizational culture, commitment to change, and leader-member exchange (LMX). We also investigate newcomer status and its relationship to reported bullying. Findings demonstrated perceived stability in the organization and higher levels of LMX showed lower levels of workplace bullying. Further, an organizational culture that emphasizes rewards lead to higher levels of bullying and newcomers are subjected to more bullying than longer service workers.     

Procyclicality of the comovement between dividend growth and consumption growth

Duffee (2005) shows that the amount of consumption risk (i.e., the conditional covariance between market returns and consumption growth) is procyclical. In light of this “Duffee Puzzle,” I empirically demonstrate that the conditional covariance between dividend growth (i.e., the immediate cash flow part of market returns) and consumption growth is (1) procyclical and (2) a consistent source of procyclicality in the puzzle. Moreover, I solve an external habit formation model that incorporates realistic joint dynamics of dividend growth and consumption growth. The procyclical dividend-consumption comovement entails two new procyclical terms in the amount of consumption risk via cash flow and valuation channels, respectively. These two procyclical terms play an important role in generating a realistic magnitude of consumption risk. In contrast to extant habit formation models, the conditional equity premium no longer increases monotonically when a negative consumption shock arrives because it might lower the amount of risk while increasing the price of risk.     

Performance Measures in Dose-Finding Experiments

In the first phase of pharmaceutical development, and assuming that the probability of positive response increases with dose, the main statistical goal is to estimate a percentile of the dose–response function for a given target value $\mathrm{\Gamma }$. We compare the Maximum Likelihood and centred isotonic regression estimators of the target dose and we discuss several performance criteria to assess inferential precision, the amount of toxicity exposure and the trade-off between them for a set of some exemplary adaptive designs. We compare these designs using graphical tools. Several scenarios are considered using simulation, including the use of several start-up rules, the change of slope of the dose-toxicity function at the target dose and also different theoretical models, as logistic, normal or skew-normal distribution functions.     

Influence of acquirer boards on M&A value creation: Evidence from Continental Europe

We examine how the size and the composition of acquirer boards are associated with shareholder abnormal returns for 2,230 M&As made by listed firms in Continental Europe. Although board size proves insignificant, our findings do offer some evidence as to a beneficial effect of board diversity on M&A value creation. Gender diversity appears marginally positively associated with acquirer shareholder abnormal returns. The fraction of foreign directors is in general not significantly positive, unless the rule of law in the acquirer country is weak. Nonetheless, nationality diversity in the board turns out harmful in purely domestic takeovers. The influence of age diversity is marginally positive, yet only in domestic and horizontal takeovers. Next, the fraction of independent directors has a robust positive effect on the acquirer CAR, while directors with multiple board appointments prove valuable especially through preventing firms from pursuing poor takeovers. Finally, CEO duality is detrimental only in industry‐diversifying deals initiated by acquirers that are not controlled by an individual or a family shareholder. Any negative CEO‐duality effect is mitigated when the acquirer‐country rule of law is strong.     

More preventive care, and fewer emergency room visits and prescription drugs--health care utilization in a consumer-driven health plan

Although consumer-driven health plans (CDHPs) have grown dramatically, the question of whether CDHPs have reduced health care costs has not been answered definitively. This article presents what the authors believe to be the first study to analyze a large sample of claims data and to look in detail at different types of utilization among enrollees in a CDHP and those in a traditional comprehensive major medical (CMM) plan. After adjusting for the finding that CDHP enrollees are both younger and healthier than those in CMM plans, the authors found that CDHP enrollees show no consistent or significant utilization differences for measures over which consumers have little control (e.g., inpatient stays); lower utilization for measures over which consumers have greater control (e.g., emergency room visits); and higher utilization of preventive services.     

Evolution of the Infant Health Production Function

Michael Grossman's seminal publication on the demand for health and health production (Grossman 1972) has spawned a substantial body of research focusing on the production of infant health. This article provides a systematic review of the published literature to date on infant health production and how it has evolved over the past 3–4 decades as data have become more available, computing has improved, and econometric methods have become more sophisticated. While empirical research in most fields has expanded in corresponding ways, the infant health production research has become an important part of the broader and inherently multidisciplinary literature on intergenerational health. The strongest and most robust findings are that policies matter for infant health, particularly those affecting access to health care, and that prenatal smoking and other chemical exposures substantially compromise infant health. Promising directions for future research include elucidating relevant pathways, reconciling the largely inconsistent estimated effects of nutrition and education, and exploring the roles of preconceptional and lifetime health care, paternal factors, social support, housing, complementarity and substitutability of inputs, factors that modify effects of inputs, and evolving medical technologies.     

Some Parallels Between Currency and Banking Crises

There is a sizeable literature on the causes of speculative attacks on fixed exchange rates and a large literature on the determinants of bank runs. Surprisingly, these two literatures rarely overlap, even though both types of crises involve attacks on asset price-fixing schemes. This paper draws a number of parallels between the work on currency crises and the work on banking crises and examines some of the new insights that are coming out of a more integrated approach in the aftermath of the Asian financial crises.     

Improved integration of LOPA with HAZOP analyses

Integrating Layer of Protection Analysis (LOPA) with Hazard and Operability Analysis (HAZOP) has many advantages over performing these studies separately. The merits include: fewer actions from the combined effort compared to performing only a HAZOP; team continuity resulting from the combined effort as opposed to two separate teams having possibly differing points of view; and, ultimately, a time and cost savings realized by the combination. This integration defines the risk associated with a given scenario, enabling better decisions that impact business assurance. By using the Center for Chemical Process Safety guidelines to define the independent protection layers upfront, the gray areas can often be reduced or eliminated; thereby enabling a more thorough LOPA. Examples include taking credit if a unit has two independent operators (outside and inside) responding to critical alarms, or taking credit for centralized control rooms that may allow immediate operator interaction and response. This article shows how the guidelines have been used successfully in joint HAZOP/LOPA studies, and describes an initial preparation protocol that can ensure high-quality results. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009     

Antecedents of growth through mergers and acquisitions: Empirical results from Belgium

This paper empirically investigates the antecedents of growth through mergers and acquisitions (M&As) in a typical continental European country, Belgium. The article reports on a study using data on 484 private and listed bidders engaging in 990 M&As during 1997-2007, and matches this sample with companies that did not pursue any external growth. By analyzing firm characteristics, industry, and aggregate financial market variables, the study can also discern the motives that are important in the decision to acquire. The results show that neither the firm's cash position nor its cash-generating abilities influence its choice to grow externally. Yet, intangible assets affect the M&A decision positively, whereas ownership concentration and bank loans have a negative effect. In industries where incumbents are operating at a lower scale and in more highly concentrated industries, the odds of firms participating in M&As are larger. Industry deregulation, industry growth, and financial market conditions have no influence. These findings are largely comparable across listed and private firms. Yet, the data do reveal that the operating scale of industry incumbents and industry concentration matter only in horizontal and domestic takeover decisions.     

Knowledge management enablers in liner shipping

This study empirically identifies crucial knowledge management enablers and examines their impacts on organizational performance using survey data collected from liner shipping firms include shipping companies and agencies. Results indicated that knowledge management enablers such as organizational structure and knowledge management culture are found to have significantly positive effects on the organizational performance aspects of innovativeness, financial performance, and customer service, whereas information technology support is a positive effect on organizational performance aspect of innovativeness. Theoretical and managerial implications of the research findings on knowledge management for liner shipping companies are discussed.
