On quantile residuals in beta regression

Beta regression is often used to model the relationship between a dependent variable that assumes values on the open interval (0, 1) and a set of predictor variables. An important challenge in beta regression is to find residuals whose distribution is well approximated by the standard normal distribution. Two previous works compared residuals in beta regression, but the authors did not include the quantile residual. Using Monte Carlo simulation techniques, this article studies the behavior of certain residuals in beta regression in several scenarios. Overall, the results suggest that the distribution of the quantile residual is better approximated by the standard normal distribution than that of the other residuals in most scenarios. Three applications illustrate the effectiveness of the quantile residual.     

Scale versus specialization: banking strategies after the euro

The euro will transform the competitive landscape of European banking. This paper discusses some of the strategic effects of the euro on banks. In particular, it explores two questions: the rationale behind mergers and acquisitions and the universal banking model. The strategic analysis of the forces for change in banking leads to some conclusions: scale will not be the key success factor in European banking, the euro will increase the role of financial specialists in Europe and the universal banking model will face numerous challenges in the new context.     

An empirical comparison of Canonical Correspondence Analysis and STATICO in the identification of spatio-temporal ecological relationships

The wide-ranging and rapidly evolving nature of ecological studies mean that it is not possible to cover all existing and emerging techniques for analyzing multivariate data. However, two important methods enticed many followers: the Canonical Correspondence Analysis (CCA) and the STATICO analysis. Despite the particular characteristics of each, they have similarities and differences, which when analyzed properly, can, together, provide important complementary results to those that are usually exploited by researchers. If on one hand, the use of CCA is completely generalized and implemented, solving many problems formulated by ecologists, on the other hand, this method has some weaknesses mainly caused by the imposition of the number of variables that is required to be applied (much higher in comparison with samples). Also, the STATICO method has no such restrictions, but requires that the number of variables (species or environment) is the same in each time or space. Yet, the STATICO method presents information that can be more detailed since it allows visualizing the variability within groups (either in time or space). In this study, the data needed for implementing these methods are sketched, as well as the comparison is made showing the advantages and disadvantages of each method. The treated ecological data are a sequence of pairs of ecological tables, where species abundances and environmental variables are measured at different, specified locations, over the course of time.     

Small area estimation of mean price of habitation transaction using time-series and cross-sectional area-level models

In this paper, a new small domain estimator for area-level data is proposed. The proposed estimator is driven by a real problem of estimating the mean price of habitation transaction at a regional level in a European country, using data collected from a longitudinal survey conducted by a national statistical office. At the desired level of inference, it is not possible to provide accurate direct estimates because the sample sizes in these domains are very small. An area-level model with a heterogeneous covariance structure of random effects assists the proposed combined estimator. This model is an extension of a model due to Fay and Herriot [5], but it integrates information across domains and over several periods of time. In addition, a modified method of estimation of variance components for time-series and cross-sectional area-level models is proposed by including the design weights. A Monte Carlo simulation, based on real data, is conducted to investigate the performance of the proposed estimators in comparison with other estimators frequently used in small area estimation problems. In particular, we compare the performance of these estimators with the estimator based on the Rao–Yu model [23]. The simulation study also accesses the performance of the modified variance component estimators in comparison with the traditional ANOVA method. Simulation results show that the estimators proposed perform better than the other estimators in terms of both precision and bias.     

IT'S WHAT YOU SAY,NOT WHAT YOU PAY: AN EXPERIMENTAL STUDY OF MANAGER‐EMPLOYEE RELATIONSHIPS IN OVERCOMING COORDINATION FAILURE

We study manager‐employee interactions in experiments set in a corporate environment where payoffs depend on employees coordinating at high effort levels; the underlying game being played repeatedly by employees is a weak‐link game. In the absence of managerial intervention subjects invariably slip into coordination failure. To overcome a history of coordination failure, managers have two instruments at their disposal: increasing employees' financial incentives to coordinate and communication with employees. Synthesizing methods drawn from psychology and economics, we quantify the impact of specific types of communication on workers' effort levels and manager's profits. This methodology allows us to rigorously compare the efficacy of communication and direct incentives in an environment where both are available. We find that communication is a more effective tool than incentive changes for leading organizations out of performance traps. Examining the content of managers' communication, the most effective communication strategy is quite simple: specifically request a high effort, point out the mutual benefits of high effort, and imply that employees are being paid well.

Investigating Institutional,Economic and Social Determinants of European Regions for Firm Growth Through Employment Generation

This paper examines the influence of the institutional, economic and social characteristics of a region on firm growth through employment generation across 14 European countries for the time period 2010–2013. Theoretically, we utilize the resource‐based view alongside insights from institutional theory to develop a conceptual framework that captures the influence of regional characteristics on firm employment growth. Based on this framework, our empirical results indicate that not only does firm growth depend on the firm‐specific characteristics found in the literature, but regional attributes also significantly impact firm growth in a heterogeneous way for different firm types. In line with the heterogeneous nature of firm growth, our results point to significant differences in the influence of institutional, economic and social characteristics on firm growth in different‐sized groups and across different rates of growth distribution. The implications of our study suggest the importance of managers and policy‐makers realizing which firms are mostly expected to benefit from the external environment, and which in turn can be planned via tailored policy reform by regional governments and firm‐level strategy‐making by managers.     

From Intended to Actual and Beyond: A Cross‐Disciplinary View of (Human Resource Management) Implementation

Despite increasing interest in human resource management (HRM) implementation as an explanation for the association between HRM and firm performance, considerable confusion remains about what implementation means. In order to develop conceptual definitions of HRM implementation and implementation effectiveness, this study builds on three different literatures outside the HRM field (strategy, innovation, and change management), which have addressed this topic extensively. As a result, implementation is characterized as a dynamic process, involving the interaction among multiple actors, starting with the adoption of a new practice and ending with its routinization. This is distinguished from implementation effectiveness as an outcome of that process. The study helps to achieve construct clarity, hence providing a more solid basis for future research and allowing for a better consolidation of findings. The authors also develop an agenda for further research by reviewing a number of theoretical and methodological approaches that have been used in implementation research across fields, including HRM. Overall, the study aims to establish implementation research as a highly relevant academic and practical quest not only in HRM, but also in other management literatures.     

Public relations anthropologies: French theory,anthropology of morality and ethnographic practices

The protagonists of this article are Lucien Matrat and the group of academics he led, known as the “European doctrine (or school) of public relations” (Boiry, 2004, p. 1). These public relations academics and professionals, who were mainly French, represented a body of knowledge which was characterised by an ethical and anthropological approach to public relations. It is this approach that led to Matrat's drafting of the Code of Athens and the creation of a theory of public relations based on human beings. The European doctrine also advocated the application of ethnographic methods to create corporate culture, such as the projet d’entreprise (corporate project). This paper analyzes, from a historical and theoretical viewpoint, this anthropological approach to public relations.
